Why does my AC keep running?

During the hot Phoenix Arizona summers, most people are use to their AC running quite a bit, just to keep up with the 110+ temperatures that we experience here. While it is normal for your AC to be on more than usual when the temperature goes up outside, it shouldn’t be constantly running. Here are a few troubleshooting tips to try before giving Sharp Air Conditioning & Heating a call that can save you some time and money.

  1. Sharp Air Conditioning & Heating, LLCCheck your thermostat – One of the most avoidable issues is to check your thermostat settings. With the more basic thermostats, it can be as simple as forgetting to switch your system from “ON” to “AUTOMATIC”. Having it in the “ON” position will tell your AC system to continue running, even when it satisfies the temperature you have set on your thermostat. With the more complex thermostat options that are on the market now, yours may need a little bit more programming to be set correctly. Check with your owners’ manual, or give us a call and we can try to walk you through some troubleshooting on your thermostat.
  2. Change your filters! – Air flow restrictions caused by dirty filters can greatly affect your AC systems performance. If you AC system does not get enough air flow, it can not blow out cold air and will continue to run since it is not able to satisfy the thermostat setting. Change those filters!
  3. Dirty coils – Check to make sure there is no debris built up on your condenser outside. This is the same as a restriction for your indoor components. Restrictions can cause the system to not cooling correctly, therefore not being able to satisfy the thermostat settings leading to a constantly running AC system.

If you go through the above steps and nothing seems to work, give Sharp Air Conditioning & Heating a call and we can send a certified technician out to assess what may be wrong. Another cause of a constantly running system can be age. Your AC system may just be worn out from years of use. If this is the case, we can work with you to best determine the next steps to take in replacement.

Why is my air conditioner blowing hot air?

My air conditioner is blowing hot air… what’s going on?

Sharp Air Conditioning & Heating, LLCAnother common call we get here at Sharp Air Conditioning & Heating is someone calling in to say their air conditioner is blowing hot air. This would seem to be even worse than if it was simply not blowing any air at all, especially when its 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.

  1. A clogged air filter – We will keep saying it over and over, 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 be a major factor in restricting airflow. Changing your filters can be one of the easiest maintenance issues that you preform on your home, it’s all about remembering to do so. With the dust storms that we get in Phoenix and the surrounding Arizona desert, changing dirty filters should be at the top of your maintenance list. Change those filters!
  2. 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.
  3. Refrigerant Issues – Sometimes your system can develop a leak in the refrigerant lines, and cause a very slow leak that can reduce the amount of refrigerant in your system. Your AC system needs to have a proper “charge”, or amount, of refrigerant in the system to operate correctly. A few tell tale 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, and we will send a professional out. This can usually be an inexpensive repair if your system is simply low on refrigerant.
  4. Condenser/Outdoor Unit – 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. 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 to 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.
