Is Your Air Conditioner Blowing Warm Air? Here’s What To Do.
It’s the middle of summer and all you want is to stay cool and comfortable in your home. But what do you do when your air conditioner starts blowing out warm air instead of cold air? Don’t panic – there may be a simple fix for the problem. Let’s explore why this is happening and how to solve it.
The Problem Could Be Your Thermostat
One of the most common causes of warm air coming from your AC unit is a malfunctioning thermostat. If you notice that your air conditioner is running constantly, even though you have it set to a cool temperature, it’s likely that the thermostat isn’t working properly. Try adjusting the temperature setting on the thermostat lower than it was before, then wait a few minutes to see if it kicks on again. If not, try replacing the batteries in the thermostat (if needed) and resetting it completely. If that doesn’t work, you may need to replace or repair your thermostat altogether.
Refrigerant Levels May Be Low
Another reason why your AC could be blowing out warm air is low refrigerant levels in your system. Refrigerants are responsible for cooling down air inside of an AC system, so if there isn’t enough refrigerant present, then warm air will blow out instead of cold air. This can happen due to leaks in the system or because too much refrigerant has been released from the unit over time. In this case, you should call an HVAC technician as soon as possible since they will need to test and refill refrigerant levels in order for your AC system to function properly again.
Check For Clogged Air Filters
If none of those solutions seemed to work, another thing you should check before calling an HVAC technician is whether or not your AC has clogged filters that are preventing cold air from coming through properly. Check all of your filters and make sure they aren’t blocked by any debris or dirt build-up – if they are, simply replace them with new air filters. Once that’s done, turn on your AC again and see if cold air begins flowing through once more!
Clogged Condensate Line
Another potential cause of warm air is a blocked condensate line. The condensate line collects moisture from the evaporator coil in order to remove humidity from the home and keep it cool and comfortable. If there’s an obstruction in this line, it will prevent proper drainage and lead to an overall decrease in performance by limiting airflow. You should check your condensate line for any blockages every few months or so and clear them if needed.
If neither of these issues are present, then you may have bigger problems on hand that require professional help—namely, a failed compressor or capacitor. A failed compressor means that coolant isn’t flowing throughout your system correctly, which will lead to warmer than normal temperatures blowing out of the vents. Similarly, if your capacitor has gone bad then it won’t be able to provide enough power for the blower motor or compressor to function properly and could result in warm air being released instead of cold air. In either case, it’s best to call in an HVAC technician who can diagnose and repair these components quickly and safely so that you can enjoy cool temperatures once again!
Keeping cool during hot months can be difficult when problems like warm air coming from an AC unit crop up unexpectedly – but thankfully there are some easy steps homeowners can take in order to troubleshoot these issues at home without having to call an HVAC technician right away!
From checking your thermostat settings and replacing/repairing parts if needed, to checking for clogged filters and making sure refrigerant levels are full – these tips should help get your AC back up and running quickly so you can enjoy a cool summer at home!
