There are many reasons your AC might not be cooling your home properly. The solution could be as easy as flipping a switch on your thermostat, cleaning a dirty air filter, or clearing debris away from your outdoor unit. There are also more complex problems that may need the help of a professional. Here are a few ways you can troubleshoot the problem.


When the summer months hit, it can be a relief to have your air conditioner working properly—but this relief is quickly ruined when you turn on your AC unit only to find that it’s not blowing cold air. While this problem may seem like a major headache, there are actually several reasons why your air conditioner isn’t blowing cold air and with just a little bit of troubleshooting you should be able to figure out why yours is not working correctly. In this article, we’ll cover some of the most common causes of an AC unit not blowing cold air so that you can get yours back up and running in no time!

It could be:

-The thermostat is set too high

-The compressor or fan motor is not working properly

-The condenser coil is obstructed by dirt or debris

-Refrigerant levels are too low

-Duct work is leaking air

The first thing to check if your AC unit is not blowing cold air is the thermostat. If your thermostat is set too high then it won’t tell the AC unit when to turn on, preventing it from delivering any cool air. Make sure that your thermostat is set at a temperature below room temperature and see if this helps resolve the issue.

If the thermostat isn’t the issue then another possible cause could be that your compressor or fan motor isn’t working properly. A compressor motor keeps refrigerant flowing through your system while fan motors help circulate airflow; so if either of these components fails then you won’t get any cool air coming out of your vents. Fortunately, both are relatively simple to inspect and replace yourself as long as you know what you’re doing—though if in doubt then don’t hesitate to call an HVAC professional for help before attempting any repairs!

A third possible explanation for why your AC isn’t blowing cold air could be an obstructed condenser coil. The condenser coil is responsible for helping convert warm outgoing air into cold incoming air; however, if it becomes covered in dirt or debris then it won’t be able to do its job and will cause hot & humid conditions in your home instead. To fix this problem simply remove all obstructions and clean off any dirt/debris using a garden hose or pressure washer (depending on how severe blockage may be). This should restore normal operation within minutes!

Finally, one last explanation might have something to do with low levels of refrigerant inside of your system (also known as Freon). Refrigerant helps transfer heat away from inside of your home so naturally when levels become too low efficiency drops and weaker temperatures result—no matter what setting you have selected on the thermostat itself! Unfortunately recharging refrigerant requires an HVAC technician since their specialized tools & knowledge are required; but once done they should be able to address any underlying issues causing leakage so that everything runs smoothly again shortly after.

In conclusion, there are many potential explanations for why an AC unit isn’t producing cool temperatures—from faulty thermostats all the way up through dirty condenser coils requiring maintenance & recharging refrigerant leaks requiring professional attention! Hopefully though now with information gathered here today readers should have a better idea about how best go about resolving their own personal cooling issues without having resorting expensive service calls every single time something doesn’t seem quite right…
