The last thing that Florida homeowners want to discover is their AC blowing hot air. Whether you prefer a cool, comfortable home or need the air conditioning to fend off allergies, a working system is a must. If you find your AC blowing hot air, try these troubleshooting steps first.
What to Do When Your AC Is Blowing Hot Air:
1. Check the Thermostat
It might seem too obvious to miss, but be sure that your thermostat is set to “cool” and that the temperature is set low enough. From curious kids to simple mistakes, discovering that the fix is as simple as pushing a couple of buttons would be a tremendous relief so the momentary embarrassment will pass.
2. Check the Breaker Switch
Many AC systems use a combination of an outdoor unit and an indoor unit. If the indoor unit is running properly but the outdoor unit has lost power, the result will be the AC blowing hot air. If you discover a tripped breaker, switch it back to the “on” position, and allow the AC to run for a few minutes. If the breaker trips again, you’ll need to contact a professional for repair.
3. Check the Filter
This is another quick fix if you find your AC blowing hot air. A clogged, dirty air filter can reduce the internal air flow to your AC unit. Without enough internal air flow, not only will your unit work harder to cool your home and drive up energy expenses, but it also will not function very well. Dirty filters can also make your home uncomfortable by circulating air that’s full of dust, allergens, and other pollutants. During peak cooling season, it’s important to replace the filter at least once per month.
4. Check the Outdoor Unit for Ice
If you discover your AC unit has ice on any area, turn the system off. If you have not already changed the air filter, check it now to be sure it’s not the source of the problem. Allow the ice to melt completely, checking from the outdoor unit to any indoor components. Depending on outdoor temperatures, this may take several hours. It’s important to resist the urge to pick or chip at the ice to speed up the process, as this could damage some of the components.
Once the ice is melted and you’ve installed a fresh filter, turn on the air conditioning again, and let it run for a few minutes. If this does not resolve the problem, it’s time to call in the pros. Be sure to turn the system back off again; continuing to operate a damaged AC unit could cause further damage.
5. Check the Outdoor Unit for Debris
Dirt, leaves, and other debris can build up on and around your outdoor unit and could result in your AC blowing hot air. Luckily, the fix for this is simple. Use a stiff broom to sweep any debris off and away from your unit, and be sure that tall grass, shrubs, and weeds are trimmed away.
Keeping Your Air Conditioner Running Smoothly
A Florida home with a well-running AC system is a happy home. Not only will your home be more comfortable, but your energy bills will be lower, too. For the best results, we recommend:
- Regular Maintenance. Scheduling a cleaning and inspection every spring will help catch small problems before they become big ones. You’ll also have some time to make repairs before the heavy summer heat arrives.
- ENERGY STAR Certified Appliances. ENERGY STAR appliances are designed to use less energy to keep your home cool, which is perfect for your budget.
- Boost Your Insulation. Insulation helps keep the cooled air inside where it belongs. The best type of insulation for most applications is spray foam because it can be added to existing structures. Spray foam also provides an airtight seal to keep your entire home more comfortable.
