Why Your HVAC Unit Isn't Cooling and What You Can Do About It

It's hard to beat that refreshing feeling of walking inside after spending time outside in the summer heat. But what if your air conditioning isn't working properly? An HVAC unit that isn't cooling can be frustrating and uncomfortable, especially during the hot summer months. The good news is that there are several things you can do to troubleshoot the problem and make sure your home stays comfortable during the summer.

Check your thermostat - One of the first things you should do when you notice a problem with your HVAC unit is to check the thermostat. You may think that the problem is with your unit, but it could be as simple as a malfunctioning thermostat. Make sure it's set to the correct temperature, and that it's not in FAN mode or even on HEAT mode instead of COOL mode. If you have a programmable thermostat, make sure the settings are correct.

Check your air filter - Dirty air filters can cause problems with your HVAC unit's cooling ability. A clogged filter will make it difficult for air to flow through the system, leading to problems. Check your filter and change it if it's dirty. This should be done at least once every three months but checked every month.

Check for clogged condenser coils - If your HVAC unit is running but not cooling, the problem may be due to a clogged coil. These coils are responsible for releasing the heat your unit collects from your home. Over time, they can become clogged with dirt and debris, making it difficult for heat to escape. If you suspect this may be the problem, turn off the unit and clean the coils with a garden hose and recommended coil cleaner.

Check for refrigerant leaks - Refrigerant is the substance your HVAC unit uses to cool your home (in this case remove heat). If there's a leak in the system, the unit won't be able to cool your home effectively. Signs of a refrigerant leak include hissing noises coming from the unit, ice forming on the refrigerant line, or warm air blowing from the vents. If you suspect a refrigerant leak, you should call a professional HVAC technician to diagnose and repair the problem.

Consider professional maintenance - Regular maintenance is critical to keeping your HVAC unit running smoothly. It's recommended that you schedule an annual maintenance visit with a professional HVAC technician to ensure your unit is in good working order. During this visit, the technician will clean and inspect your unit, making any necessary repairs and changes.

An HVAC unit that isn't cooling can be a frustrating problem to deal with. Fortunately, there are several things you can do to troubleshoot the issue and maintain optimal performance from your HVAC unit. By keeping your thermostat, air filter, condenser coils, and refrigerant levels in check, you can keep your home comfortable and cool all summer long. And don't forget the importance of professional maintenance to ensure your unit is running at its best. By following these tips, you can keep your HVAC unit functioning properly and enjoy a cool and comfortable summer.
