Whether your HVAC system is a few years old or new, regular maintenance is necessary to ensure that it operates efficiently. Scheduling routine professional checks can improve your indoor air quality and overall comfort. However, there are also a few maintenance tasks that you can do to avoid costly repairs.

Changing HVAC Filters

One of the biggest maintenance tasks that will keep your air conditioner running smoothly is to change the HVAC filters. Every system has an air filter, and it’s usually located in a blower compartment or return air duct.

Before you replace the filter, though, make sure that you turn off the unit. Leaving it running allows the dust and dirt that the filter usually catches to enter the system, which can damage the evaporator coil. Make sure that you use the right filter size and type for your unit too. You can find this information on the current filter.

Note the date of the replacement so that you know when to change the filter again, which should be every month or two. Call a professional if the unit doesn’t turn on afterward.

Checking the Condensation Line

While your air conditioner is running, the air that passes over the evaporator coil in the indoor unit creates condensation. The moisture goes into a drain pan and through the condensation line to the outdoors. It’s important to make sure that this line isn’t clogged because it can overflow the drain pan and cause water damage in your home.

The condensation line is usually a white CPVC pipe, and water should drip from the outdoor part of the pipe when the AC is turned on. You could also slowly pour some water down the drain to test if the line is clear. If the water builds up, then you need to call an HVAC specialist to unclog it


Looking for Obvious Problems

With your AC running, check the indoor vents for proper airflow. You can check for signs of water leakage around the indoor unit as well. On the outdoor unit, you can check that the fan is turning and the compressor is making a low hum. If you notice airflow issues, water leakage, an idle fan or strange noises, it’s time to call for repairs.

In addition, there’s a refrigerant line on both the indoor and outdoor units. You should see condensation forming underneath the insulation around the pipes, and they should be cold to the touch. If you see frost or ice around them, though, don’t touch them. This is a problem that requires professional attention.
