What Goes into Central Air Conditioner Maintenance?

While we have discussed the need for regular air conditioning maintenance and its importance in maintaining the energy efficiency and life of your central air conditioning system, you may be wondering – what exactly does the HVAC technician actually do during a service?

Here are a few of the things done when a technician performs maintenance on your central air conditioner.

Cleaning the Condenser Unit

This involves removing leaves and debris from the outside and inside the unit. The cooling fins are cleaned and any fins that are bent are straightened. The fan motor is also lubricated so that it continues to run smoothly.

Cleaning the Evaporator Drain

The evaporator coils for most central air conditioning units are sealed. They can only be accessed by a licensed technician. The evaporator drain is what carries moisture away from the evaporator coils. If puddles of water appear beneath the coils, then it’s possible that the drain pipe is likely clogged with algae and bacteria.

Changing the Air Filter

This one is easy, and should actually be done by the homeowner at least once a month when the AC is used heavily. A dirty air filter can cause problems for your central air unit. The location of your filter will depend on your system. Sometimes the filter may be located on the condenser, other times it may be found around the evaporator. To change the air filter, you must remove any grilles or housing, makes sure the area is free of dust and debris, and then replace it with another of the exact same type. You can find the filter part number and size dimensions on the old filter.

Air Ducts Inspection and Cleaning

Did you know that a single leak in your ductwork could be costing you as much as 25% of the efficiency of your home’s heating/cooling system? Checking your ducts for leaks is important, as it can reveal energy loss and a potential entryway for contaminants.

Moisture, dust, pollen and other contaminants in your air ducts can create a breeding ground for molds and spores. Potential health effects and symptoms associated with mold exposures include allergic reactions, asthma, and other respiratory complaints. Cleaning the ductwork removes contaminants and increases the airflow efficiency of your ductwork which can save energy.

Coolant Check

The insulation on the lines running from the condenser outside the evaporator to inside the house is checked. If they are worn or damaged,  they will need to be replaced. If the AC system does not contain the proper amount of Freon, your system will provide very little cooling. If the system needs a charge, it will be performed. If you suspect a Freon or coolant problem, call a professional to recharge the system.
