This is one of the most dreaded things to happen during the summer — your air conditioner kicks on, you can hear the whir of the blower going, but your home never gets any cooler. Then, all you have to show for it is an overheated house and a higher energy bill. Ugh! So what causes this issue to happen? Here’s what you need to know if your A/C is on but not blowing cold air.
Check the Basics First
Before you start worrying about expensive air conditioning repair, take a step back and check the basics first. The reason your A/C is struggling to blow out cold air could be as simple as a dirty filter. If enough dirt and dust build up on your filter, it could inhibit airflow, meaning you won’t feel the rewards from your A/C’s hard work. Check the filter, and if it’s dirty, swap it for a clean one. Also, check the type of filter you have. In some systems, the super-filtering options, like allergy or HEPA filters, can inhibit airflow. Try replacing it with a standard filter to see if that helps.
The other issue could be that your fan is on, even when the A/C isn’t cooling. Check your thermostat and verify that your A/C and fan are both set to “auto” instead of “on.” This will help ensure that your system can take a break when your home cools to the appropriate temperature. If you’re looking to keep things cool, try stationing some fans around your home to move cool air to any spaces that struggle to get as cool as the main living areas.
Check Your Condenser
The big, whirring unit of your HVAC system that lives outside your home is the condenser. This is the portion of your air conditioner that clears away the hot air that gets produced when your A/C is running. Basically, it makes sure that your air conditioner doesn’t have to work even harder to provide you with cool air. If your A/C is struggling to produce cold air, that might be because the condenser is dirty, and the debris is trapping hot air around the evaporator unit inside. If the outside unit is gunked up, rinse it off with a hose, but make sure you use a gentle setting so the condenser’s fins don’t get bent.
Call For HVAC Repair
At this point, if your A/C system still isn’t producing cool air, it’s time to call for professional air conditioning repair services. The following issues will all need the help of a professional to assess and fix.
While you’re checking the filter, take a moment to look around your A/C unit. If you see signs of frost on any of the pipes, it’s important to turn your system off right away. This could be a sign of a refrigerant leak, and if your system is left to run with low or no refrigerant, it could do permanent (and expensive) damage to your compressor. Also, if you hear bubbling/hissing noises from your system, or if your A/C cools at night or on cool days but struggles on hot days, these can also be signs of low/no refrigerant.
The other common reasons your A/C doesn’t blow cold air could be because of the condenser itself, or a problem with the condenser fan. In either case, you’ll need a professional A/C repair technician to diagnose and repair the issue.
