Educated property owners realize that heating and air conditioning systems need maintenance, but not all home and business owners know exactly what to do or which common problems are easy to fix and which ones require a pro. McDevitt Air wants to be your local source for heating and air conditioning information and we want to be your first call when you need help. Below are a few helpful tips for dealing with common air conditioning problems.

Common Air Conditioning Problems

  • The air is not cold enough: When air is moving through the vents but it isn’t effectively cooling the space, check the filters. Too much dirt and dust restricts airflow, which keeps the system from being able to work efficiently. In some cases, the ductwork might have developed a leak that is allowing cool air to escape. Another possibility is that there may not be enough refrigerant in the unit. This could point to a leak in the system that needs to be repaired before the refrigerant is recharged.
  • The air is not cold at all: Again, this could point to a problem with the level of refrigerant in the unit. There could also be a problem with the condenser. Either way, this situation is best left to a certified technician.
  • The system won’t turn on: Unfortunately, there are many reasons for a system shutdown. Do some investigating to see if you can narrow down the problem before you call for repair. First, make sure the thermostat is working and is set properly. A broken thermostat could prevent the system from coming on. Next, check the electrical panel for a tripped circuit breaker. It’s generally fine to reset a tripped circuit breaker once. If your system trips the circuit a second time, you need to call for professional repair. Don’t tackle electrical problems yourself. If the circuit isn’t the problem, you can also inspect the outdoor unit. It may not come on if it is choked with yard debris such as grass clipping and branches. You can clear away the exterior material, but you should call a pro to do a full cleaning and maintenance check.
  • The AC frequently cycles on and off: If your system has been doing this from the beginning, it may be too powerful for your space. If it’s a new problem, you could have too much dirt in the condenser or evaporator.
  • It’s making unusual noises: Noises from the outer unit can sometimes be resolved simply by clearing away twigs or other debris. Unfortunately, these noises could also point to damaged fan blades, failing parts or other serious issues. Don’t let the situation go on too long as it could lead to even greater problems.
