The last thing you want is to get back home from a long day out only to find your AC malfunctioning. With extreme weather conditions, you need to know how to diagnose your system, which gets you a step closer to getting it running again. The following are the most common reasons why your AC is not blowing cold air.
Dirty Air Filter
When was the last time you had your filters changed? Dirt accumulating can interfere with the free flow of air and, in extreme cases, damage parts of the system, leading to malfunctions like the AC failing to blow cold air. That’s why experts recommend that you change your filters at least once every 30–90 days.
Wrongly Calibrated or Malfunctioning Thermostat
Another explanation for why your AC unit is not blowing cold air is because of the thermostat. Have you set it correctly? Maybe the settings are not right, or sometimes, the thermostat may be malfunctioning due to electrical issues. Our HVAC company in Dupage County will check that for you, diagnose it for power issues or damages, and help you set it up correctly.
Wrong AC Sizing
Did you know that the size of your AC affects its performance? If too large or too small for your house, you will likely run into issues like failure to blow cold air. Your system will either overwork or struggle to provide a comfortable temperature for your home. Before installation, experts first size your home and recommend the best AC that will work perfectly. Otherwise, you will have to replace it.
There Is a Leak in Your Ductwork
Your home AC may not be blowing cold air because your ductwork is leaking. That means that you may be losing the cold air to the attic or walls, but it never reaches the space it intended to. This prevents the air from reaching you and also affects the efficiency of the system. So, it will have to work harder, which takes a toll on its performance.
AC Is Due For Maintenance
If you want your AC to last and work efficiently through its service life, remember to schedule regular maintenance. This way, you avoid costly repairs and other malfunctions while your system stays energy-efficient and works optimally.
