It’s very important that your HVAC system is maintained to avoid unwanted problems and costs. A contractor can help you keep your heating and cooling system running at peak performance by doing annual checkups. It’s best to have your heating system checked in the fall and the cooling system in the spring. A good rule of thumb is to have the unit checked when the time changes each spring and fall.
A professional should check the thermostat settings as part of the maintenance checkup. The thermostat settings should work so that the temperature is comfortable when you are home and should save energy when you are away. All electrical connections should be tightened and the voltage measured. The parts should be lubricated. If lubrication is lacking, friction will increase the amount of electricity use. The condensate drain should be inspected when the unit is in cooling mode. If the drain is plugged, water damage can occur and humidity levels can be affected. Making sure that the controls of the system are working properly is also significant.
For cooling specifically, the evaporator and condenser air conditioning coils should be cleaned. The system’s ability to cool is reduced by dirty coils. The refrigerant level should be checked and adjusted if necessary. If the refrigerant is not at the right level, it can cause the system to be less efficient, which increases energy costs and reduces the life of the unit. The blower components should be cleaned and adjusted to provide proper airflow, which will allow for greater levels of comfort. Your systems efficiency can be reduced by up to 15 percent if it has problems with airflow.
When it comes to the heating checkup, a professional should check the gas connections, gas pressure, heat exchanger and burner combustion. If gas connections are operating improperly, fires can occur, and if the burner is dirty or the heat exchanger is cracked, the burner won’t operate correctly. Both can cause the equipment to work less safely and efficiently.
There are some things that a homeowner can do to help ensure that the HVAC system is working properly. It’s a great idea to inspect, clean and change air filters monthly. A contractor can show you how to do this. Most people don’t understand that a dirty filter can damage your equipment and increase energy costs, which can then lead to early failure of the system.
