Thermostat settings: Operator error is actually the top reason that air conditioner blows warm air. You may have inadvertently set your thermostat to the heat setting, and now the furnace has kicked in. Before you panic and think you need AC repair in Visalia, CA, check to see if your thermostat is actually set to cool. It may also be set to have the fan cycle on, which circulates the air in your home but doesn’t introduce cool air into the space.

Clogged air filter: When was the last time you changed your air filter? A dirty air filter could be the reason behind why your air conditioning system is pushing warm air into your home. When your air filter is dirty, it clogs the passage of airflow and won’t let the cool air produced flow into your home. Change your filter regularly to ensure you don’t have to experience this issue when you’re trying to stay cool this summer.

Dirty coils: Without staying up to date on proper maintenance of your air conditioning system, your condenser coils can fail to operate correctly. Dirt can get trapped in and around them, making them less effective at their operation. Having regular maintenance checks by an HVAC company can ensure your air conditioning coils stay clean and operational all summer long.
