If your house has a cooling system, regular HVAC maintenance is necessary to prevent operational issues. However, many homeowners aren’t sure how to care for their units. If this is your first time owning a cooling system, use this guide to get informed on how to prevent problems.

What Causes the Need for HVAC Repairs?

1. Faulty Thermostat

A broken thermostat can’t register the indoor temperature correctly, making it challenging to keep the home cool. This issue typically results from running the air conditioner longer than normal. Replacing the thermostat with a newer model will restore the AC’s efficiency and give you more control over its energy usage.

2. Dirty Air Filter

Changing the air filter every three months is an easy HVAC maintenance task; however, it can be easy to forget. Dirty filters cause ACs to overwork themselves and use more energy since they need to push air through the clogged mesh. Additionally, a full filter releases pollutants into your living spaces, diminishing indoor air quality.

3. Frozen Evaporator Coil

If the evaporator coil becomes too cold, the moisture in the air passing over it will freeze and turn into ice on the coils. If your cooling system has been running for a while, shut it off so that the coils have time to defrost.

4. Damaged Condenser

If your system doesn’t run properly or cuts off prematurely, the problem may be with the condenser. This part is the large unit that sits outside and helps cool the air. Since it’s outdoors, it’s exposed to various elements and conditions that can cause damage. Keep the unit clear of leaves, sticks, dirt, and other debris that may impede its function.
