Why is my air conditioner blowing hot air?
My Air Conditioner is Blowing hot air… what’s going on?
Another typical call at Sharp Air Conditioning & Heating is someone calling in to say their air conditioner is blowing hot air. It is even worse. We also offer services of AC repair in Gilbert.
Then if it was not blowing any air at all, especially when it’s hot enough outside without a heater blowing inside too! Below are a few common reasons for this “hot problem” and what you might be able to do to fix it.
Your unit’s refrigerant levels may be low if your air conditioner spews warm air. Unfortunately, this often means that your system has a refrigerant leak! If that’s the case, your air conditioner will keep running and blast heated air to match the thermostat setting.
Sometimes your system can develop a leak in the refrigerant lines and cause a prolonged leak that can reduce the amount of refrigerant in your system. Your AC system needs to have a proper “charge,” or amount, of refrigerant to operate correctly.
A few telltale signs of a refrigerant leak could be ice forming anywhere on your system, or you might even see an oily substance on your outside unit. If you see any of these signs, give Sharp Air Conditioning & Heating a call for heating and cooling Mesa AZ, and we will send a professional out. It is usually an inexpensive repair if your system is low on refrigerant.
A Clogged Air Filter
We will keep saying it repeatedly, but clogged air filters are the number one culprits for many HVAC issues. While a dirty filter might not be the sole reason your air conditioner is blowing hot, it can significantly restrict airflow.
Changing your filters can be one of the most uncomplicated maintenance issues you perform on your home; it’s all about remembering to do so. Changing dirty filters should be at the top of your maintenance list with the dust storms we get in Phoenix and the surrounding Arizona desert. Change those filters! Call us for an air filter change service.
Check Thermostat Settings
Every now and then, we get a call that we fix over the phone. Usually, the root of the problem is someone has unknowingly changed the settings on their thermostat. It can be as simple as forgetting to change over to “cool” in the spring, or the system may just have the fan on. Checking your thermostat settings before calling in an AC issue can save you time and hassle.
Another common issue that we get called out on is that it seems the inside fan is blowing, but the outdoor unit, also known as a condenser, does not seem to be on. The first thing to do, as a homeowner, is to check to see that the unit has power or that a breaker has not been tripped. Simply making sure the breaker is in the “ON” position can fix your issues.
Another easy fix to look for is to clear debris from your condenser. If you can see dirt and leaves and other “stuff” stuck to the sides, this will restrict your system, and it will have a hard time cooling. Again, with the Haboobs that we get here in Phoenix, Mesa, and the entire valley, dirt can build up very quickly, so a quick check can save you discomfort when you need the AC the most.
