6 Troubleshooting Steps When Your AC Blows Hot Air
Your air conditioner is working hard for much of the year keeping you cool hopefully no matter how hot it gets in Corpus Christi. But unfortunately, sometimes that demand becomes too much for a home’s system. You might not always catch problems with your AC, but some problems are too obvious to miss.
An air conditioner starting to blow warm air is a major red flag that something is wrong with your home’s HVAC system. It could appear to be sounding like it’s running fine but it has stopped blowing out the cool air it’s supposed to. It doesn’t take long for a Corpus Christi home to start heating up when the AC is no longer cooling.
The good news is that even if an air conditioner is blowing warm air, that doesn’t mean it is an expensive fix. Some minor issue or one that is easy to fix may be the cause of the problem. An AC that has stopped blowing cold air may be repairable. In fact, a professional HVAC technician, like those at Tiger Heating & Air, can likely get your cooling system back up and running in no time.
BEFORE CALLING FOR REPAIR SERVICE: HOMEOWNER TROUBLESHOOTING STEPS
Before even calling for a professional repair, you may want to check out a few things on your own. It is possible that the issue why your AC is not blowing cold air is so simple, you can fix it yourself!
Here at Tiger, we receive calls all the time from people across Corpus Christi in distress over a broken air conditioner. There are times when we go out to service an HVAC system, we find it only required very minor and easy fixes. While we are more than happy to service your broken cooling system, we want to provide you with information that may help you avoid having to pay for a service call altogether.
HOMEOWNER TROUBLESHOOTING STEPS FOR AC BLOWING HOT AIR
#1: CHECK THE THERMOSTAT
Check to make sure that your thermostat is set to COOL. If it is set to only FAN or HEAT, then switch it to COOL.
And check to see if it is set to be COOLER than the current temperature. Perhaps someone changed the setting without you knowing. Just lower the thermostat setting to a number below the current temperature in your home.
#2: CHECK VENTS THROUGHOUT YOUR HOME
Do you see that any of your vents are closed? If so, open them. Closed vents can cause problems with the air flow and cause your AC to blow warm. It’s a common misconception that vents should be closed in room not in use, but that is not correct. While a couple closed vents may be okay, too many can cause a problem.
#3: CHECK THE INDOOR HVAC UNIT
Most HVAC systems have a portion of the air conditioning system (the evaporator) located inside the home often in a closet or the attic. This evaporator absorbs heat from the air and transfers it to your outdoor AC unit (the condenser). This indoor unit has the fan that blows conditioned air through your home, and it does this even if your outside unit is not working. Check to make sure you hear the blower motor running.
#4: CHECK YOUR AIR FILTER
Is your filter dirty or clogged? While you are examining the inside unit, take a look at your air filter. If it is dirty or clogged, that could be the reason why your air conditioner isn’t blowing cold air. Simply changing it out for a clean air filter may get your system working correctly again.
#5: CHECK THE OUTSIDE AC UNIT
Your condenser works to create cool air that the indoor fan circulates in your home. Look at your condenser for problems. Is there frost or ice on it? What about leaves or debris?
If it is frozen or has frost, change the setting on your thermostat from COOL to FAN. Let that run for as much as 12 hours to help your unit thaw. A frozen condenser is often caused by a dirty air filter, which is another reason why making sure you regularly change your filter is so important.
A frozen unit can happen when the coils on your evaporator become dirty or clogged. If that’s the case, clean the coil if you can access it. To get a good clean coil may require the coil is pulled out of the space it is in and Tiger can help you with that.
If you do one of these steps and it only solves your problem temporarily, you may have a more serious issue. If the AC freezes up again, call Tiger Heating & Air for 24/7 emergency AC repair service at (361) 371-7541. A freon leak could be what is causing the problem. We can come out and handle any potential leak, refill the system, and ensure it is back to working properly and safely.
#6: CHECK YOUR HOME’S POWER
If you see that your AC isn’t blowing any air at all, then another thing to check is your home’s power supply. You may have blown a fuse and need to turn a switch back on inside your breaker box.
