Why Is My AC Blowing Hot Air?
We are truly in the heart of the summer in New Castle when the floor fans and the open windows just don’t cut it anymore. You head over to your thermostat and select “air conditioner” and wait for that refreshing icy air to start blowing out of your vents. When you check a few minutes later, you feel only hot air. Why?
Many reasons can cause an air conditioner to malfunction, resulting in warm or hot air blowing through your vents. Our Burns & McBride professionals want to help you diagnose those problems quickly and then get them fixed, so you can cool down your family and your home.
Start at the Thermostat
The thermostat controls when your heating, ventilation and air conditioning (HVAC) system turns on and off, depending on what temperatures you have designated. When your air conditioning system blows hot air, start by checking your thermostat.
Be sure it’s set correctly and not set to heat. You need to set your thermostat to cool, being sure you’re not only setting the fan function. If you are sure you have it set correctly, there may be an issue with how your thermostat is sending messages to your HVAC system or some other problem. Call us to come out and fix the issue for you.
Lack of Air Circulation
Air conditioners need plenty of air circulation to operate correctly. Start by checking your air filter and being sure it’s clean. Clean air filters can not only improve your air conditioner’s performance but can help save significant amounts of energy.
Make sure that all of the registers are open. Many homeowners think that it they close registers in the rooms that are not being used that this will help cool the rooms they DO use. Not True. The ductwork is designed to act as a system and choking down parts of it reduces the airflow and can cause problems
Then, head on outside and be sure your unit is not buried under leaves, grass, weeds or other yard debris. If there are things blocking the outside unit, take the time to clear them away. Once that’s taken care of, check the inside unit for any blockages or clogs that may be restricting airflow there.
Too Much Ice
Sometimes restricted airflow and dirty condenser coils can cause a buildup of ice on the outside portion of your air conditioning system. If too much ice builds up, it can cause your air conditioner to malfunction and blow only hot air.
If a great deal of ice exists, you may need to turn off your entire system and allow it to defrost. Once the ice melts, clean the condenser coils, and turn your system back on to see if it functions properly. If it doesn’t, call one of our professionals to help.
If you the steps above didn’t help – it’s time to call a professional
