The following are some things to check when your air conditioner isn't cooling your space. Check and reset the thermostat. Clean the area around the compressor. Another reason why your air conditioner works but doesn't cool down? It has clogged or blocked coils.
If the air conditioner turns on and the thermostat is set correctly, but the system does not cool down, the air condenser may be dirty or blocked. The first step is to check the outdoor unit and clean the surroundings and remove any debris or weeds that are blocking air circulation. A clogged or clogged condenser coil could cause the air conditioner to work but not lower the indoor temperature. The condenser fan brings air to the outdoor device through the condenser coil to extract thermal energy from the house while it works properly. The air conditioning system may include an air filter located inside or around the indoor air treatment unit.
The filter traps dirt, dust and other airborne particles when they enter the air treatment unit. It keeps the components inside the system cleaner and working more efficiently, and it can also help keep the air in your home cleaner. A dirty air filter can block airflow and reduce cooling in your home. In more extreme cases, it can cause the system to shut down completely.
If your air conditioning system has any of the above symptoms or simply smells a lot and you haven't done it before, it's time to turn it off and call a trusted HVAC professional to inspect it. Your central air conditioning system usually requires two separate switches for the interior and exterior parts of your home air conditioner. A heat pump looks the same as an air conditioning unit, with a few different components inside that allow it to cool and heat your home. Depending on its severity, a refrigerant leak can help keep the air conditioning system from blowing cold air, it can operate for longer periods of time without properly cooling the house, or it can cause the compressor to damage or fail and shut down completely. A central air conditioning system that doesn't work properly not only makes your home uncomfortable, it also hurts indoor air quality and wastes tons of energy.
If you made it this far in the article, it's likely that your air conditioner is working but it's not cooling your house. There are several reasons why your air conditioner may be working but not lowering the temperature in your home, from basic problems such as a misconfigured thermostat or a dirty filter to more complicated situations that require replacement of parts. So, if your air conditioner works all the time and blows in enough cold air, but still doesn't cool your house properly, the heat is probably radiating into your home, and insulation and air sealing are part of the solution. If your central air conditioning system isn't working properly and your teenage years are approaching, it's time to prepare to replace it.
In either case, it's best to call an HVAC technician to determine the root cause of the clogged or blocked air conditioning coils. Air conditioning systems are more than just the condensing unit (the air conditioning unit or the heat pump) outside the house. There are several factors involved in sizing a system for your home, including square footage, quality of construction and insulation, local climate and more. And finally, if your air conditioner doesn't cool your house but it's still working and expels cold air through some vents, it could be your ductwork.
It's going to be the hottest day of summer, and no matter how many times you turn down the thermostat, you'll notice that the air conditioner doesn't blow out cool enough air. If your house is hot and uncomfortable, but the air conditioner is working properly, insufficient insulation and air leaks are often the reason why the air conditioner can't cool your home.
