Many people perform basic air conditioning maintenance on their own. They change filters, clean around the unit, and vacuum the coils. However, to really keep your HVAC operating at top efficiency and prevent future problems, you need to have professional air conditioning maintenance services performed regularly. Here are just a few items they do during a routine service call.

Calibrate the Thermostat

If the thermostat is not properly calibrated, the AC will run more often than necessary to keep your home cool or won't run enough. The technician will check that this part is not being affected by a heat source, like a bright light or sunbeams. They also make sure that it is accurately measuring the air temperature of the room. They may suggest adding more thermostats in the house that are connected to the system.

Lubrication

There are moving parts that need to move freely like the fan and any bearings. The tech will lubricate them so they do not get stuck. If the fan does not rotate easily, the whole system can not push cooled air into the house.

Amperage

The blower motor and all the capacitors need to be operating with the proper amperage to work efficiently. Technicians will do this and replace any parts that are not right if the part cannot be repaired. They will also make sure the compressor has the proper amperage going to it. 

Refrigerant

The proper amount of refrigerant is vitally important to the efficiency of an AC unit. In fact, if there is not enough the system will only blow hot ait. If there is not enough refrigerant in the system, they will top it off. They may also flush the system and refill it completely if they feel things are gunked up inside the coils. 

Wires and Connectors

Wries and connectors can be affected by weather or pests getting into the system. A good maintenance service will include inspection, repair, or replacement of all wires and connectors in the unit. 

Sometimes you do not notice that the AC is not working as efficiently as it could. When you have professional air conditioning maintenance services work on your system on a regular basis, you can be sure the system is working properly. In addition, they will also be able to see small issues that could turn into bigger problems if left alone. The money you spend on a service call will save you money on your cooling bills and also keep you from needing costly repairs.
