Leading Causes of Air Conditioner Problems

With summer only a couple short months away, it will soon be time to crank up the air conditioning in your house to escape the heat. Hopefully when you turn down your thermostat, the cool air starts blowing and makes a difference right away. However, sometimes, AC units can have problems, leaving you victim to the sweltering heat of summer.

If you’re experiencing air conditioner problems in Visalia, CA, one of these top causes might be the culprit:

  • Thermostat issues: Your thermostat may not be calibrated correctly, keeping it from communicating accurately with your air conditioner—especially if you have an older thermostat. This problem can typically be fixed by purchasing a new thermostat or recalibrating your existing one. If you have a programmable thermostat and you still seem to be having issues, try checking the manual to make sure it is set correctly.
  • Fan issues: Inside of your unit, two fans ensure that you get the cool air you need—one blows over the evaporator coil to cool the air, and the other blows over the condenser to get rid of the heat that was absorbed. If either of the fans has a faulty motor, worn-out belts, excessive dirt or low lubrication, this can lead to air conditioner problems in Visalia, CA.
  • Leaking ducts: If there are breaks or holes in the ductwork, the cool air might be leaking in to the wall or ceiling instead of your living spaces. This will cause your unit to have to work harder than normal, increasing the cost of energy.
  • Clogged drains: Drain lines help remove the moisture from the air, sending into a pan and down the drain. A clogged drain or line or a full pan can cause the water to back up, potentially damaging the unit. The water could also leak, going in to your walls and ceilings and causing mold growth if it isn’t caught early.
  • Low refrigerant: Refrigerant takes away the heat and humidity from the air in your home or business. If your unit has a leak, there might not be enough refrigerant to cool the air down. You will need to have the holes fixed and the refrigerant replaced.
  • Frozen evaporator coil: This coil absorbs the heat from the air and houses the refrigerant in your system. If the coil gets too cold, ice may form on the outside and the coil, which needs warm air around it, will stop working properly. This will cause either warm air or no air to come through the vents.
  • Dirty condenser coil: This coil gets rid of the heat from the air, expelling it outside. If it gets dirty, the coil cannot work properly, hindering the heat transfer and leading to more wear and tear.
