What to Do When Your Air Conditioner Isn't Cooling After a Tune Up

When your air conditioner isn't cooling properly after a tune up, there are a few things you can check to try and get the system working again. First, make sure that the filter is clean and that the thermostat is set correctly. If the air conditioner turns on and the thermostat is properly adjusted, but the system does not cool down, the air condenser may be dirty or blocked. Check the outside of the unit and clean it, removing any debris or weeds that are obstructing air circulation.

If your home air conditioner isn't cooling properly, it indicates that there's a deeper problem with the air conditioner that needs to be addressed. Turn it off and have it repaired right away. There are several reasons why your air conditioner might be working but not cooling down. It could be a problem with the thermostat, compressor, or evaporator coils.

Or it could simply be clogged with dust and dirt, preventing it from working properly. If the air conditioner blows cold air but doesn't cool the house, there could be a leak in the house to the outside. Check that all windows and doors are closed. If the air feels colder than room temperature, it may not actually be at the desired temperature and it could just be the fan blowing.

If your air conditioner is turned on and set up properly, but it still doesn't cool your home to your standards, you may have a unit that isn't the right size for your home. One of the first things you should check if you notice that your air conditioner is working but not cooling is the thermostat. Not to mention, dirty air filters can cause air conditioners to smell musty and create extremely poor indoor air conditions. If it's a normal summer day and your air conditioner is still not working, you may have a problem with charging or that the evaporator coil is frozen.

The indoor fan draws hot air into the air conditioning unit, and if it is dirty, it will not be able to bring in enough air to cool the house. If the air conditioner doesn't cool, but you feel that little air is coming out of the vents, there may be a problem with airflow.

When your AC isn't cooling as expected after a tune up, there are several potential causes you should consider before calling an HVAC technician for help. A dirty air filter can restrict airflow through your system and prevent it from cooling effectively. Additionally, if your thermostat isn't set correctly or if there's an issue with your compressor or evaporator coils, these can all lead to an inefficient cooling system. It's also possible that there's a leak in your home or that your AC unit isn't sized correctly for your space.

If you're having trouble getting your AC back up and running after a tune up, DeZiel Heating & AC can help diagnose and repair any issues you're having with your system. An experienced technician can check for any blockages in your condenser unit outside or any other problems that could be preventing your AC from cooling properly. They can also inspect your indoor fan to make sure it's drawing in enough hot air for your system to cool down effectively. An indoor air treatment unit (oven or fan), an evaporator coil, an air filter, a thermostat, and copper tubing (refrigerant lines) connecting indoor and outdoor systems are all common components of split-system air conditioners.

If any of these components aren't functioning correctly or if they're clogged with dust or dirt, they can prevent your AC from cooling as expected after a tune up. When you're dealing with an AC system that isn't cooling properly after a tune up, enlisting professional help from DeZiel Heating & AC can help get your system back up and running quickly so you can enjoy comfortable temperatures in your home again.
