Thermostat Settings
Start by checking your thermostat settings. While this may seem simple and obvious, sometimes you or someone else in your household may have put it in the wrong setting or improperly programmed it.
When it comes to cooling your home, having clogged air filters and a dirty evaporator coil can be the culprit for why your AC unit does not supply cold air.
Since your air filters are designed to prevent dust, dirt, and other pollutants from circulating in your home, it's important that you regularly change your air filter so that it doesn't get clogged. A clogged air filter obstructs free-flowing air from circulating from the AC unit and into your home, which means that your AC unit can't operate smoothly.
Additionally, depending on a clogged air filter can lead to a dirty or frozen evaporator coil. Evaporator coils are also responsible for cooling your home as they absorb heat. But, when they are dirty, this can cause your coils not to operate normally. You may need professional coil cleaning in addition to filter changeouts, which are typical HVAC maintenance plan benefits.
Compressor Malfunction
A compressor is a system that circulates refrigerant through your AC unit. When your compressor is damaged or malfunctioning, it won't be able to move the refrigerant through your AC unit. This alone can prevent cool air from circulating in your home. A licensed HVAC technician is needed to fix this issue.
Outdoor AC Unit Blocked
For your AC unit to function properly, it's crucial that the space around it is freed up and that nothing majorly obstructs it. If your unit is placed in an area where landscaping is overgrown or where debris could easily clog it, this can impact its normal operation and prevent cold air from being supplied into your home.
In addition to your other household responsibilities, it can be taxing to keep up with ensuring that your outdoor unit is properly maintained and cleaned. Our HVAC Supreme Maintenance Plan, takes care of this for you with a professional cleaning and wax of your outdoor unit.
Refrigerant Leak
Located inside the copper coils of your AC unit, refrigerant is a chemical that is responsible for cooling your home. But if cold air is not blowing out even if you have the right thermostat setting and your coils are clean, this could be an indicator that you may have a refrigerant leak. It's important to get this problem fixed as soon as possible. A refrigerant leak is an environmental, health, and safety concern.
Last but not least, electrical issues can cause your AC unit to blow out warm air. This could be from your outdoor AC unit losing power, which can be caused by a blown fuse or a tripped circuit breaker. Also, it's important that your outdoor AC unit is properly wired so that it can operate properly.
