No Cool Air Coming from Your Air Conditioner

On a hot day in Tacoma, you shouldn’t be stuck with an air conditioner that only blows warm air into your home. While there may be many reasons why your air conditioner fails to blow cool air, some of which are detailed below, a qualified technician can usually identify the issue and offer the repairs you need.

Thermostat Issues

The first place you should always look when your AC is not blowing cool air is the thermostat. Check to make sure the AC is turned on and try lowering the temperature a couple of degrees. There may be a calibration issue, or a sensor may not be able to accurately detect the temperature in your home.

Low Refrigerant

A constant level of refrigerant cycling throughout your system is necessary to keep your home cool. As the refrigerant changes from liquid to gas form, it absorbs the heat from your home, and as it condenses, it dissipates heat outdoors. The refrigerant itself is never supposed to leave your system; if you have low refrigerant levels, it is likely due to a leak somewhere in the refrigerant lines. Only AC technicians are qualified to handle and replace refrigerant, so you should always contact an air conditioning repair service if a leak causes your system to stop cooling.

Frozen or Dirty Coils

The indoor evaporator coil and the outdoor condenser coil are both vital to the refrigeration cycle. The condenser coil is where refrigerant changes from gas to liquid form, giving off heat to the outside air in the process. The evaporator coil is where refrigerant evaporates into a gas, absorbing the heat from the air inside your home. Over time, these coils may become dirty, which can interfere with the cooling capacity of your system. This is why it is necessary to schedule regular maintenance to check for issues such as a dirty coil. Blocked airflow can also cause the evaporator coil to freeze, which could prevent your system from blowing cool air.

Don’t suffer without a working AC any longer than you have to this summer. Call Sound Heating to set up AC service in Tacoma and get your air conditioning system back to normal.
