Air duct

It is undeniable that air conditioners are the most favorite cooling appliances at this time. They are popular all around the world. They are one of basic home appliances, particularly during the summer months when usually the peak heat air temperature of the hottest days around us. There are available several types of them, and basically they are consisted of three favorite types; central ac units, window ac units and portable air conditioning units. The big drawback of using these units is the unexpected high energy bill that you should pay for each month. The high energy utilities to operate them are influenced by some crucial factors, but basically depends on three main factors; the extreme weather situation of your local area, how users operate them, and the efficiency technology of the unit itself.

Like other commonly appliances, there are also some frequently problems of air conditioners that should be anticipated by homeowners as well. Those problems are usually closely related to the proper maintenance and the age of the unit itself. The older units usually tend to fail easier than the newer units. Those problems is varies from the minor problems that could be solved by yourself to the heavy problems that probably you have to hire a professional service. In addition, by understanding the warning signs of a potential matter with your air conditioner device are so helpful that could save your money and your time in the future. Therefore, why are you not to recognize your unit closer?

Ok, below is helpful guide and information about some frequently problems of air conditioning units:

1. The unit cannot cool the room optimally. It is usually caused by the wrong size, low on Freon, or the dirty air filter. Duct cleaning is also recommended and helpful to keep unit work powerfully.
2. The leaking water, basically it is common effect of condensation process when the unit is beating the heat. One general reason suggestion to analyze this case is perhaps the ice is already formed on the unit. The ice formed could be cause by the improper operation of thermostat controller or unit is forced to cool the air at too lowest temperature.
3. If you use portable or window ac models then usually you will hear the unfriendly noise from them when running. Both models cannot work as silently as like central ac types. In fact, there are times when the noise could increase louder than it is! The amount dirt that is accumulated on compressor could be the reason of the louder noise.
4. The other common problem is the loss of refrigerant. It is not simply case and require high skill to fix it out. Therefore, by hiring a professional technician is not too bad idea.
5. Next, the electrical problems. It is familiar but could make the unit turn off completely. It could be caused by the bad performance of Freon mechanism (leaking) and the poor performance of fan motor.
6. The unit seems working properly but in the end of the month you get the unexpected high energy bill. It means the unit is no longer at its maximum efficiency performance. There are some helpful DIY maintenance recommendations to keep unit works efficiently such as; cleaning or replacing the air conditioner filter properly and periodically, cleaning the coil, etc.
7. The last, the proper maintenance should be obeyed. And usually, we can find the further information about it in the manufacture’s instructions of the unit.

A chemical that is used in refrigeration systems (like air conditioning units) is usually called as refrigerant. This chemical has crucial function to help air conditioners to remove or beat the heat and relocate the heat on the outside of the indoor rooms. The other applications that use it are industrial cooling machines, automobile or car air conditioners, etc. Its phase usually from liquids to gases and finally back to the liquids again. When it is changing to gas from liquid (evaporating process) then it will absorb the amount heat of the nearby area and eventually this process leads to the cooling effect of heat transfer.

There are available some types of refrigerants and usually to distinguish those types, they usually are named with “R-variable” in the HVAC (Heating, Ventilation, & Air Conditioning) industry. Some popular of them at this time are R134a, R-22, R-505, etc. Each type has unique characteristics and the variety of chemical make-ups and different properties. Therefore, we can fins some types of them that only can work in low pressures while other types could work in high pressures. In addition, according to ‘Montreal Protocol’ in the 1987, the use of R-22 (CFC-s or chlorofluorocarbons) will be significantly limited due to its bad effect that can deplete the ozone layer. Therefore, the use of this type is ideally only allowed for special servicing existing applications in the future. And some types that are purposed to replace the R-22 refrigerant 9 which theoretically friendlier to the environment) are R134a (for residential and automotive air conditioning units), R-11 refrigerant is for commercial purposes, and ammonia that usually for industrial equipments.

# R-22

Like mentioned before, this refrigerant is also familiar known as HCFC-22. It has been used for more than forty years. Unfortunately it can be categorized as greenhouse gas that also result HFC-23 (by-product) that can significantly contribute bad-effect of ozone depletion and global warming processes. Therefore there are many countries (including the U.S) all around world have agreement to reduce the domination of R-22 completely in 2010 (according to Montreal Protocol)!

# R410a

It is the bright future of refrigerant technology that not only prioritizes friendly to our environment (like written before) but also (in line with technological development) it is also trusted can provide the greater efficiency performance that eventually so helpful to cut the energy consumption for each year. Sometimes the new technology is accompanied with some doubts! Therefore, there are some doubt questions and points that should be anticipated or answered as well to guarantee a new technology can be successfully accepted, such as; reliable or not, stability or not, how about the economical value, etc.

#Challenges of making R410a more popular than R-22!

Unfortunately the new eco-friendly technology of R410a air conditioning refrigerant also has cons that should be addressed quickly by engineers. It has higher pressure while operating at normal temperatures! Therefore the refrigerant system must be buffed up! It also requires different oils that make it cannot be combined with the existing of R-22 air conditioner. Its oil tends absorb the moisture easily. This is one of reasons why a technician or HVAC contractor perform evacuation when dong the installation of a new unit.

# The conclusion

Overall, R410a air conditioning refrigerant is more recommended if you want to get the better investment in the future. They offer green alternative technology that not contain chlorine or non CFC refrigerant, energy bill saving in long term, and can work or cool your room quickly or even faster than R-22! In addition, although their initial costs could two to three times higher than the older R-22 models at this time, but this situation could change in the early of the phase out period in 2010! And the last, the successful buying is always choose the product that is not destined to get shopworn, isn’t it?

Free standing swamp cooler

Swamp coolers are the alternative solution, if you don’t like to the performance of air conditioners because of their Freon mechanism that can damage the ozone layer. They can be categorized as eco-friendly technology that can work with the evaporation principle. The costs that you must pay when using these systems are lower than then energy bill of air conditioning units. Unfortunately, their performance will optimum or not is closely influenced by the level of humidity and the outside temperature. They can work optimally if the environment humidity in you local area is not too high. Therefore, they are not recommended to any area geographically. They are perfect choice for areas that have dry climate. Several popular types of them that currently available are portable models, window mounted types, roof-mounted units, etc.

Like air conditioners or other home cooling appliances, swamp coolers also require the proper maintenance to ensure they keep working excellently. If you have adequate budget, why not to get a sign contract with a qualified HVAC contractor in your local area for the maintenance, at least once a year. However, fortunately you can also do a little DIY maintenance to your unit. There are some parts or components that should be checked and maintained regularly with DIY option, particularly if those parts don’t get the serious damage. The further information about the proper maintenance procedures usually can be found in the manufacture’s instructions. Overall, the swamp cooler maintenance needs a little more than conventional AC. Let’s explore more detail about it below!

(1). Clean the outside of unit! It is easily procedure that helpful to prolog the lifetime of the unit and will make it looks clean at the first glance. Make ensure the unit is not in use (in turn off mode) then you can use the down cloth to wipe it down. Note; as possible to avoid using detergents or other harsh chemicals!

(2). Then, ensure the evaporative cooling pads are still in good condition or not. The pads are usually made from materials that resistant to mildew like the aspen wood shavings! It is so recommended to replace the pads minimum once in two seasons. The ideal time to replace them is usually at the beginning of on-season (summer season). Pads could be damage because several factors like poor quality of water. In addition, replacing the pads is usually one package with removing or cleaning the belts. Ensure they are free from crack and wear!

(3). Next is water tank cleaning. It is important procedure especially if your local area has hard-water! In necessary, you can use the mild shop to make the cleaning process can be finished easier. Check the normal water lever when the unit working, make ensure it is not too low or too much water. If you see it is not normal you can make it normal by adjusting the float valve. Low water level will make the unit cannot work maximum and on other hand too much water is too risky to stimulate some leakages problem.

(4) Make ensure your room has adequate ventilation for air circulation. It is important in order to keep the continuous supply of humidity and outside temperature for the unit. And during the DIY maintenance, please ensure everything is put back into the proper place and no-visible gaps!

(5). Storage suggestions! The pads and air filter should be removed before you store the unit. Remove the water in the tank and drain it completely! Choose the location that dry and far away from the foot traffic. You can use the original box or a cover to protect the unit and its all parts securely during off-season.

Air conditioning compressor

Well, compressor is important part of air conditioner unit. It is placed outdoor of the room and usually together with outdoor components like condenser. It is also usually sealed into a single unit. Motor is important component of compressor and has important function to move refrigerant gas through evaporator coil and ducts from indoors of the house. The other component is cylindrical piston. On the down stoke, it has function to direct the refrigerant gas and then compress it on the upstroke with its moves down and up performance. Overall, the function principle of compressor either in AC for residential houses/ buildings or in cars is the same!

The proper performance of air conditioner compressor gives the drastic contribution to the performance of the unit. Therefore, the regular maintenance (minimal once a year) is so recommended to keep it on its best performance. If you find it has already worn out then replacing is the option that cannot be compromised. It usually has specific serial number that basically to help a homeowner to find the new one easily. And if you get this problem and your compressor has not yet expired on its warranty period then you can contact the manufacture of your AC unit is the best solution. You can give the detail information of the compressor that you require to them, and then they usually shall likely replace it free. In addition, most of manufactures usually provide around 4 to 10 years lifetime warranty on their air conditioning compressor products.

Well, the procedures on how to remove or replace the air conditioner compressor are not easy, particularly if you don’t have the adequate skill (beginner). And this process could take more than twenty hours. Hmmm… below are some basic procedures that may be helpful for you and finally you find the answer why it is difficult to be finished quickly:

1. First, preventing the unwanted electrical incidents, make ensure the electrical disconnect box of the unit is in turn off mode.
2. Next, you need the refrigerant recovery machine to recover all refrigerant. This process usually will always need the refrigerant hose connection between port and machine and recovery tank. Getting more detail information, you can read in the manufacture’s instructions of the recovery machine.
3. Open the cover of electrical service box by using the nut driver to remove the screws. It is required because there are available some modes that share the compressor access with this box.
4. Then try to access the compressor! Maybe you will need to remove the fan and also its shroud, and once again it depends on the model of the compressor. In addition, there are also available some models that use metal-flat panel. It is usually installed on the side of the box next to the condensing unit. Be careful to the wires when removing the fan or panel, some of them may remain connected.
5. The insulation cover is usually installed around compressor. It is purposed to enhance the efficiency performance of air conditioning unit. Therefore, you should remove it before finally remove the cover. As additional information, the insulation is usually made from plastic material and designed with snap buttons in order to keep it on its place properly.
6. Next, take apart the electrical connection in the compressor’s cover. You can make it easily by using the flat screwdriver. Then find the thin slot and depress it with the flat-head of your screwdriver when fetching the cover away.
7. Then, 3 wires that connect to the electrical terminal must be disconnected.
8. Use the wrench to unbolt some bolts of compressor from the floor of outdoor condensing unit.
9. Use the acetylene or O2 torch to heat the solder joint to the bottom of refrigeration line with the result that solder drips or melts. Do with the same procedure when heating the top refrigeration line! Don’t forget to use pliers when taking the refrigeration line. As additional tip, by removing the bottom refrigeration line first is so helpful to minimize or avoid the accident risk of skin burns.
10. Then you can use the wet rap to cool the solder connections faster but better you let them cool down naturally.
11. And finally, now you can try to lift the air conditioner compressor properly from the unit!

Central air conditioning

Central air conditioner maintenance should be done minimum two times a year, particularly in the early of on-season (spring) and in the end of on-season (autumn). Both periods are the best time for the maintenance in order to ensure your unit is ready to work efficiently and properly during hottest summer months. As additional tips, if you have a plan to hire a service company, make ensure you get the deal with a credible company and the ideal price. There are many ads that offer unreasonable cheap cost service in order to lure consumers such as the maintenance cost only $39.00 (it is so different if we compare to the normal cost). Be careful to it, maybe there are available hidden costs for you!

Well, like other home appliances, central air conditioners also require the periodically maintenance. There are two popular options of it; DIY maintenance and by choosing to hire a professional man. DIY option is recommended if your unit only need simply maintenance procedures. It is free cost but so helpful to ensure the unit keep working properly and optimally. On other hand, if your unit gets complicated problems or requires difficult maintenance procedures then by using a service company (although you have to pay extra cost) is not too bad idea to ensure your unit get the best service and back to its optimal performance should be. Some parts of the unit that usually must to be checked or cleaned periodically are compressor, condenser, condensate drain, drain-ways, air filter, etc.

The first thing that you should understand clearly is about central air composition. It is usually divided into two main categories; indoor unit (motor, thermostat, and evaporator) and outdoor unit (condenser & compressor). What the functions of those parts? The component that has function to push the air from inside to outside (outdoor unit) is motor. Evaporator usually has function to remove and control the moisture, it is important to make unit can cool the air easier and quickly. Then condenser and compressor have crucial function to release the amount heat to outside of the room from the house. Both are also important to control the cycle mechanism of the fresh air from outside into the room. Well, below are some simply DIY-maintenances that may helpful for you:

#The inside-maintenance procedures:

The evaporator coil and drain line of condensate are usually will become the focus attention of these procedures. As well, we know that drain usually become the favorite place for the moistures. Therefore ensure it clean and there are no leaks!

The evaporator coils are also should be kept clean, why? Because dirty coils that usually due to debris will cause the airflow mechanism process that across over the coils run hardly. This situation could cause the unit works not-efficiently that eventually will result high energy bill in the end of the month. Occasionally, the evaporator coils cleaning maintenance is not easy, depends on the condition of the coil itself. Therefore if you feel not-expert about it, better you discuss about it to a professional repair man first.

There are some methods to clean evaporator coils: (1) Using fin cleaners and foam HVAC coil. Some experts say that this option require the low costs and also not too bad choice that not only clean the fin and coils but also so helpful to disappear odors. (2) By using compressed air mechanism! It is simpler and quickly method. (3) The third option is condenser coil removal. It is not too popular than the previous methods.

#The outside maintenance procedures:

You can use light brush and a hose to remove the dirt from compressor and condenser. How to clean the compressor? Below are simply guides that may helpful:

1. First, ensure the compressor unit is not in use! Next, any noticeable debris must be cleaned from the exterior of the unit.
2. The screws usually are used to bind the grill cover with the external compressor. Open the grill by unscrewing the bolts carefully and make ensure there are no any wires-disconnect.
3. Next, try to clean any leaves and debris by using wear gloves manually and carefully.
4. If there are remaining debris that difficult to be removed then by using spray nozzle on the hose is not too bad idea. Don’t forget to ensure there is no water that accumulating in the vent by attaching the spray nozzle on the top of pipe.
5. The last, ensure the unit is dry completely before screwing the grill back on.

Next… How about air conditioner condenser coils cleaning?

1. The first step, you have to remove the unwanted dirt around of the exterior of condenser.
2. Then to make the cleaning process easier and effectively you can buy and use a commercial coil cleaner product in your local area.
3. Soft brush is so recommended to clean the fins! Please be careful when removing the protective grille. There are available some tools that to straight the fins, such as “Fin Comb”.
4. As possible please keep the level of condenser not-vertical or horizontal during cleaning process. It is helpful to minimize the risk of unwanted incidents that could damage the other condenser’s components.
5. For further information, usually you can find the perfect guides on the manufacture’s instructions of your AC system.

Well, if you find some problems that make your central air conditioning system cannot work properly, below are three simple check lists that so recommended to check your AC unit smartly before calling a service company:

1. The vent is so familiar and requires simply work principle when working but has significant contribution to decide your AC unit work well or not. But unfortunately there are still many homeowners ignore it. It is usually placed inside of the house. Open and check the return vent, particularly the air conditioner filter. Ensure it is still feasible to use (not dirty). Bad performance of dirty filter will cause the system to freeze up. This situation eventually will make the system works hardly and consume larger amount energy than the normal should be.
2. The next common reason for AC will not work properly is the bad performance of condenser coil. Therefore better you clean it regularly, how? Like mentioned before!
3. If both indications cannot solve the problem, try to shut down the system for several hours. It is so helpful if your AC is being froze-up. But if all those recommendation still cannot solve the problem, by hiring a repair man or HVAC contractor is so advisable!

portable air conditioning unit

The air conditioner checking maintenance is important procedure that so useful to ensure your ac unit keeps working efficiently and properly when the weather hottest months come into your house. This procedure is also helpful to make the unit has the high probability of getting longer lifetime in over long term. Well, there are some tips that you can complete by yourself, to inspect if you able to solve the problem DIY before contacting a professional repair man. The DIY maintenance procedures are usually simply and free-cost but so helpful to give significant contribution to the performance of the unit.

The maintenance ac procedures are dependent on the specification of the unit. And basically, the information about it can be found in the manufacture’s instructions. The difficulty level procedure of large size central air conditioner usually is more difficult than the smaller units such as window ac models or portable air conditioning units. Generally, some parts that require periodically checking are thermostat, filter, condenser coils, compressor, and still many more! The performance of thermostat is crucial to set the temperature level when unit in use. Bad thermostat will make user cannot set the temperature as accurate as his/her desire. And this situation could result unexpected energy bill in the end of the month.

As well, we know that portable ac appliances usually require non-permanent installation (can be installed or reinstalled so easily). They can be moved practically and easily as obvious as their portable nickname. Therefore, their minimum set-up procedure (indirectly) causes the simpler maintenance. Below are some basic recommendations on how to maintain the free-standing ac units properly:

1. Portable ac units are usually designed not only superior to beat the heat but also as dehumidifier. Improving the quality of cooling process, the moisture from the air is required. And the rest of water condensation (excess water) must be removed from the unit. Drainage house is usually required to collect the rest of excess water. It must be kept not overflow or the unit will shut down automatically. The frequently overflow that usually due to user negligence is not too good for the lifetime of the unit. The units that are designed with self-evaporating model (can remove the excess water automatically and continuously) is so advisable if you don’t like the drainage pump technology.
2. The other part that you should check periodically is air conditioner filter. The frequency of cleaning or replacing for the filter is dependent on the quality (or type of filter itself) and the outside air environment of the local area where you live.
3. Don’t forget to clean the space area where the appliance is housed and the outside bottom of the unit. Both are simply maintenances but so helpful to make unit keep operating powerfully and even will make it gets longer lifetime.
4. The last, consider about the proper storage procedures if the winter months (off season) comes. The unit should be storage properly, it is important to ensure your appliance will remain in good condition to face the next summer season. The proper steps of storing are: Unplug the unit as well => Make ensure that all water is ready drained completely (use the fan mode!) => Check the filter is clean! => Don’t miss to secure the hoses and cord as well! => Choose the storage location that dry and clean. => The last, by using ac cover is perfect choice and so recommended!

Air conditioning condenser coils

There is important unit of AC that has function to release the amount heat to the outside of the room that is air conditioner condenser! It is usually placed in the outside of the house (side or back yard of the house). Supporting its function to push out the high air temperature, it is usually equipped with large or medium fan. This fan has function to draw the air across over the coil elements. Ensuring this unit keeps working properly then 6 inches clearance to the wall is the minimum value of the distance that so recommended to install it! It is purposed to provide adequate space while it is running. Make ensure that it is not covered while in use.

Well, copper and aluminum are the primer materials of the coils (in order to make the coils are capable to reduce the thermal (dissipate heat) then usually the cooper material is designed with sleeves-metal attached to the fins-metal). Getting the proper cleaning maintenance to your air conditioning condenser, you need some maintenance’s equipments such as water source, garden hose, nozzle-spray, etc. Those tools are usually dependent to the amount dirt level, location of the components that will be cleaned and type. Some people have opinion that using extra chemical substances is helpful to make the cleaning process will run easily and quickly. This opinion is not wrong absolutely, but if you are not master to do it or don’t have experience to do this option before, then better you avoid it! Because basically chemical is not needed and even wrong composition or wrong chemical substances may destruct the materials of condenser’s components.

Choosing to use water or hot water is safest. Don’t miss to ensure the air conditioner condenser is in turn off position. It is important procedure because of two main reasons; (1) not all active electronic components are supported to react to water as well, it could result electrical short circuiting incident, (2) and when the condenser’s fan in use then this situation will blow water up and eventually you will get trouble to focus the water direction to remove the dust. Don’t miss to check flattened-large section of fins! If you find them, you can get them normally straiten by using a flat screwdriver. It is simply procedure but also important to help and enhance the air-flow process.

Bad or good performance of condenser coils will influence significantly to the efficiency performance of the air conditioners. Without it, the AC units will not run optimally and properly that finally also will bring the unexpected high cost of monthly high energy bill! Even if the coil is too dirty then eventually will affect of resulting the AC unit break down. Because most of coils are usually designed to surround the compressor unit then they usually will gather dirt quickly and easily. Therefore homeowners should clean them periodically to keep the AC unit keeps running efficiently and properly in the over long term.

If you rare to do the maintenance, then the condenser’s components are perhaps getting the serious problems of dirty and rusty! For this situation, you may need extra proper chemical substance for the cleaning maintenance. There are available many types of chemical cleaner. And your important big task is about choosing the best one of them that compatible with the specification material that coils and other components of condenser are made out of! Usually, you can find the further information about it more detail in the manufacture’s guidelines of your air conditioning unit.

Geothermal heating and cooling system

Well, in line with the increasing awareness of using eco-friendly technology is safer to help and keep the environment balance then the popularity of heat pump air conditioners is also increasing day by day. They not only environmentally option but also can provide fresh cool air into the room powerfully and even more efficiently. They usually are designed as HVAC system that also superior to heat your house during coldest winter months. Like other common air cooling systems, basically they cool the house by moving the heat from one area to other location. This principle has been amply utilized in many types of commercial industries. And basically it is the basic principle of Thermodynamic Law.

If you familiar and understand about how the common air conditioning systems work clearly, then you will able to learn how the heat pump systems work easily because basically both have the similar of the work principle. Most of heat pump units usually are identical with a system that utilizes not too large amount of energy to replace or move the heat (as like written before). The heating and cooling system are constructed into one system. It means the separate mechanism to cool and heat the air is not required (the effective design). Although they need fuel to result much less energy that will be used to move the heat, but they usually only use simply transfer heat. Therefore, it is not surprising if they call as real efficient eco-friendly technology that so recommended at this time.

Unfortunately, geographically some experts have opinion that heat pump HVAC systems cannot work optimally in any areas. The moderate climate areas are the ideal geographic locations where they can run in their best performance. Their initial cost (installation cost) is relatively higher or expensive! But there are many testimonials or reviews on internet that say you will get the return-cost around five years with their great efficient performance (lower energy bill). The proper installation is super important factor that can influence their performance while running. Therefore by contacting or hiring a qualified HVAC contractor is the best option so far to ensure the system will work properly and optimally. You can also ask to HVAC contractor about is you local area qualified to use them or not!

Choosing to use heat pump air conditioners (non-Freon systems) is not only helpful to reduce your expenditure finance of paying the high monthly utilities’ energy costs but also you can participate to minimize or decrease the global warming process. Because according to the trusted studies reveal that they are so helpful and useful to cut and reduce the carbon gas emission. In line with the technological developments, now most of them come with lightweight and effective design that so helpful to make them can operate more and more efficient (more than 30-40 percent or more).

Even if we compare to the conventional air conditioners, geothermal heat pumps can provide the electric energy savings up to seventy percent or more (source: EPA). Although they will involve higher initial cost (around $8,000) but they can save your money around $1,400 for each year and reduce the Carbon Dioxide gas production up to 5 tones / year (source: energy saving trust)!
