Most people feel hot and uncomfortable when the temperature reaches 80 degrees Fahrenheit. Thankfully, air conditioners (AC) can keep people cool and comfortable.
Nothing is more frustrating than when your AC stops blowing cold air, especially on a hot summer day. If this unfortunate event happens to you, there are some different issues you can check. Keep reading to learn the common reasons your AC is not blowing cold air and what you can do to get it up and running again.
Issues With the Thermostat
Start by checking the thermostat settings. You want to make sure you have it set to “cool” and nothing else.
Check the temperature in the room and look to see that the AC temperature is set to a lower degree. Sometimes, a simple reset of the thermostat is all it takes to fix your AC problems.
Dirty Air Filter
One of the most common AC problems is that the air filter on the AC is clogged with dust and debris. If this happens, the airflow coming out of the AC can be restricted.
Check your air filters and replace them if they appear dirty. Replacing the air filter can improve your AC’s performance. Checking and replacing the air filter should be on your AC maintenance checklist so you can keep your AC in its best shape.
Refrigerant Leaks
One of the more common air conditioner repairs focuses on refrigerant, which is the key ingredient to keeping you cool. Low refrigerant levels can keep your AC from getting cold enough to dispel cool air.
If you think you have a refrigerant leak, it’s important to call a professional. This is one problem that requires specialized skills and equipment to diagnose and fix.
Frozen Evaporator Coil
The evaporator coil is a device inside the AC system that pushes refrigerants through the unit to absorb humidity and heat. If your AC has low refrigerant levels or is dirty, the evaporator coil in the AC unit can freeze.
If this is what’s wrong, you’ll have to turn the AC unit off and give it time to thaw. If thawing and cleaning the evaporator coil doesn’t do the trick, it’s time to call in the professionals.
Preventative Maintenance Tips
One of the best ways to keep your air conditioner in its best working order is to stay on top of its maintenance.
- Schedule regular maintenance checks
- Keep the condenser outside clean
- Remove debris from the condenser
- Check refrigerant levels
- Check the air filter
If anything looks amiss or if you have any other HVAC system issues, it’s time for an AC check-up. Professionals can diagnose and fix the problem.
