Why should one service their air conditioner regularly?
Homeowners fail to realize that their AC Unit is the most expensive system in their home and because it is a system, it needs annual care to maintain proper functionality. Simple things like changing your filters regularly and hosing down your AC Coils can not only prevent major damage to your air conditioning system but save you money on electricity as well.

Without regular maintenance an air conditioner loses about 5% of its original efficiency for each year of operation. This means that the 14 SEER units that you bought just a few years ago may be functioning like a 9 SEER unit today! The good news is that you can recover most of that lost efficiency through regular maintenance. Studies show that with regular tune-ups a unit will maintain up to 95% of its original efficiency. This means that the cost of an annual tune-up is recovered very quickly in savings on your monthly electric bill and reduced repair costs. A properly serviced air conditioner will also do a better job of dehumidifying your home. Many local air conditioning firms offer special prices at this time of the year. Some even offer annual service programs that insure that you will be reminded of the need to service the unit at the beginning of the cooling and heating seasons.

The service check should include cleaning the condensing unit coils, checking the amp draw of the compressor, oiling the fan motors, checking that belts are well adjusted, and checking the system operating pressures and temperatures against the manufacturer’s specifications. One of the most important items to check is the coolant level (previously known as Freon) in the air conditioner. A system that is only 10% low on coolant will cost about 20% more to operate!

Humidity control was the problem that originally spurred the need for air conditioning. Basically, a person feels the heat more when there is more humidity. Lack of humidity control in hot, humid climates, in particular, can lead to mold growth and other moisture-related problems. High indoor humidifies can lead to health and comfort problems.
Most of the air conditioners of present time dehumidify as they cool, these can be seen from the water drain as the humidity drips away in form of water droplets but this dehumidification is incidental to their main job of controlling temperature. They cannot independently control both temperature and humidity.

In hot, humid climates the incidental dehumidification that occurs may not always be enough to keep the indoor humidity conditions acceptable. Maximum dehumidification happens not at the hot times of the year—when the air conditioner is running a lot—but at mild times of the year when the air conditioner runs very little.

Although there are some leading edge air conditioning systems that promise to independently control humidity, conventional systems may not be able to sufficiently control the problem and can cause comfort or mold problems in certain situations. Some current high-end systems have enhanced dehumidification, but when the existing system cannot sufficiently dehumidify, it may be necessary to buy a stand-alone dehumidifier.

The air conditioner's evaporator coil and condenser coil collect dirt over their months and years of service. A clean filter prevents the evaporator coil from soiling quickly. In time, however, the evaporator coil will still collect dirt. This dirt reduces airflow and insulates the coil, reducing its ability to absorb heat. To avoid this problem, check your evaporator coil every year and clean it as necessary.

Outdoor condenser coils can also become very dirty if the outdoor environment is dusty or if there is foliage nearby. You can easily see the condenser coil and notice if dirt is collecting on its fins.

You should minimize dirt and debris near the condenser unit. Your dryer vents, falling leaves, and lawn mower are all potential sources of dirt and debris. Cleaning the area around the coil, removing any debris, and trimming foliage back at least 2 feet (0.6 meters) allow for adequate airflow around the condenser."

At the start of each cooling season, inspect the seal between the air conditioner and the window frame to ensure it makes contact with the unit's metal case. Moisture can damage this seal, allowing cool air to escape from your house.

In the winter, either covers your room air conditioner or removes and stores it. Covering the outdoor unit of a central air conditioner will protect the unit from winter weather and debris.

When your air conditioner needs more than regular maintenance, hire a professional service technician. A well-trained technician will find and fix problems in your air conditioning system.

The technician should:

Check for correct amount of refrigerant.

Test for refrigerant leaks using a leak detector.

Capture any refrigerant that must be evacuated from the system, instead of illegally releasing it to the atmosphere.

Check for and seal duct leakage in central systems.

Measure airflow through the evaporator coil.

Verify the correct electric control sequence and make sure that the heating system and cooling system cannot operate simultaneously.

Inspect electric terminals, clean and tighten connections, and apply a non-conductive coating if necessary.

Oil motors and checks belts for tightness and wear.

Check the accuracy of the thermostat.
