Most appliances call for maintenance once per calendar year. Heating and cooling systems have more needs than your other appliances, so they need to be serviced more frequently. There are a lot of HVAC maintenance tasks the average homeowner can do themselves.
The maintenance tasks performed on an HVAC unit keep it working efficiently. Some tasks should not be performed by a homeowner. They should be performed by a licensed HVAC specialist. By following a recommended maintenance schedule, you can ensure that minor problems are repaired and do not cost you more later.

Developing Your Maintenance Checklist
There is never an appropriate time for an HVAC unit to fail. But they always choose to malfunction at a time you need them the most. By performing your maintenance tasks regularly, you can reduce the risk of a minor problem shutting down the entire unit.
Frequent Maintenance Through the Year
The area around your HVAC unit should be kept clear of debris, and your grass should be trimmed away from it. There should be nothing within three feet of the unit. You should visually inspect your HVAC system for problems and visible debris. You should have a professional check for dirty evaporator coils, dirty condenser coils, frozen coils, damage to fins, and whether the system sounds like it should.
There are several tasks that should be performed every three months to ensure that your HVAC unit remains fully functional. Change the air filters in your HVAC unit at least once every three months. This ensures that they do not become clogged and that proper air flow is maintained. In some regions, the air filter should be changed monthly during warmer months.
Test your thermostat regularly to ensure the temperature reading is correct. An incorrect reading could be the first sign of a damaged thermostat or wire. Make sure to check all of your electrical connections and replace any wires or connectors that appear worn.
Fall and Winter
In the fall, you should have your heating system inspected by a licensed technician. They will check every aspect of the system to ensure that it is functioning properly. Check your carbon monoxide detector and make sure to replace the batteries. Replace your heater’s humidifier wick and turn the water on so you have time to check for leaks in the water supply. Make sure that you dust off your outdoor HVAC unit frequently during snow. A small amount of ice is normal during the winter, but if your unit is developing sheets of ice, call a technician.
Spring and Summer
Before the last snowfall in spring, have specialist inspect the A/C portion of your unit. They will check all the components to ensure that they are not worn and they will function properly. Your technician will also inspect the refrigerant lines and electrical connections as well.
During the spring and summer, inspect your refrigerant lines regularly. The larger line should feel cold and be covered with condensation. If it does not feel cold to the touch, your unit may be low on refrigerant. Call a technician to service it before it becomes problematic.
