Oh no! When you switch on your air conditioner only to discover that the air coming out of your vents is hot instead of cold, it’s a frustrating feeling. It’s particularly annoying when you want to cool off on a hot summer day or during a heatwave.

Before you call for Schaumburg AC repair, you can check a few common issues yourself. If you have any questions, or need help, the Schaumburg HVAC experts at On the Mark Heating & Air are just a phone call away!

1) Examine Your Thermostat’s Settings

Did someone unintentionally raise the thermostat’s setting, or worse still, switch it to “Heat” rather than “Cool”? Before you start to worry about your air conditioner, make sure all of your settings are exactly how you want them.

Check that each setting on your programmable thermostat is accurate. If you switched from “AM” to “PM,” this could be the reason your AC is blowing warm air. Verify that someone didn’t simply modify the thermostat settings as a joke or because they weren’t sure what they were doing. If you recently allowed a child to play with your phone, they might have messed up the thermostat settings!

2) Clean Out Your Air Conditioner

Your outdoor air conditioner’s evaporator coils may collect dust and dirt. Remove the lid, then gently wash these. Take the time to thoroughly clean them, then restart your system because it is these coils that actually cool the air in your home. This simple task will have a big impact on how well your air conditioner works and how efficiently it can chill your house. To avoid harming the device, be sure to do this gently, as some components of your air conditioner can be delicate.

3) Check Your Circuit Breaker

Has your circuit breaker accidentally flipped? This may occur occasionally if the circuit is overloaded or the breaker needs to be replaced. In fact, it probably occurs more frequently than you realize! It’s recommended to check your breakers before you call for expert AC repair in Schaumburg because we receive many calls where the breaker is the issue instead of the air conditioner.

4) Change Your System’s Filter

Your system’s whole supply of air must pass through the filter. The system won’t receive enough air if the filter is clogged, and the consequence may feel like heated air is blowing out of your vents. Depending on the specifics of your system and how frequently you use it, most filters need to be changed anywhere from once a month to once every three months. Your A/C will struggle if you wait too long. Read more in our blog post All About Air Filters.
