When the heat of the summer arrives, you are going to want your air conditioning system to be working properly. You shouldn’t have to be sitting in an oven when you could be cool and comfortable.

Inspect the Thermostat
While it may sound simple, there are many people that call our team when their air conditioning is blowing hot air instead of checking their thermostat. Prior to contacting a licensed technician, we recommend checking your programmable thermostat to ensure it’s not set to a high temperature. If you have a mercury thermostat, sometimes turning the dial all the way to the coldest position and then back to your desired setting will fix the problem. If that doesn’t do it, you might have a faulty thermostat, capacitor or compressor. That is when you call the professionals on our team to receive assistance with an air conditioner that is blowing warm air in your household. We can diagnose the issue with your HVAC system and implement a solution tailored to your needs.
Check For a Tripped Circuit Breaker
If everything is fine with your thermostat, but you cannot hear your air conditioner running, the next step is to take a look at your circuit breaker. Check to see if the breaker is tripped. If so, flip it back on and listen for your air conditioner to kick on.
Use a Cleaning Solution to Remove Dirt & Debris From the Air Conditioner
If your air conditioner is running, but it isn’t producing cold air, go outside and check your air conditioner. If there is an abundance of weeds or tall grass growing around the cooling tower, they could be blocking the air flow and causing your air conditioner to blow warm air. Cut down the weeds and see if this fixes the problem. If you don’t immediately feel cold air coming out of your vents, don’t panic. Remember that you will need to wait for an hour to see if the problem has been resolved. Occasionally, you should gently rinse off the A/C using a mild cleaning agent like Simple Green to clean off any dirt and debris that have collected on your unit over time.
Dirty Air Filter
If you’ve checked the coils outside and they are free of weeds, grass, dirt and debris, a contaminated air filter may be the reason your air conditioning system is blowing hot air. If the air filter is blocked with a lot of dust and particles, the air isn’t getting through into your home. A clean air filter allows air to move into your HVAC system efficiently. It is a good idea to get into the habit of replacing your filter once every 3 months. Good airflow is essential to cooling your home.
