What Causes an Air Conditioner to Freeze Up?

When your AC unit freezes up it can be both inconvenient and expensive. The most common reason for this problem is lack of airflow, generally caused by a dirty air filter. Without the free flow of warm air through the AC and over the evaporator coils, these coils can become cold, ultimately freezing and icing over. If a dirty filter is the cause, then replacing it will help solve the problem. However, in some cases, an AC system freezing up can also be linked to low refrigerant levels, damaged ductwork, a malfunctioning blower fan or motor, or a clogged condensate drain - in which case you’ll need to contact our Alexandria AC repair pros to get your system running again.

While an air conditioner freezing up is a common indication of a problem with your system, it is not the only sign you should watch out for that could point to a repair being needed.

What Are the Signs Your AC Needs Repair?


Why Does My Furnace Keep Turning Off?

While furnaces are an integral part to your home’s comfort during the cold winter months, they can unexpectantly shut off without warning. The reasons why this happens can vary, but some of the most common culprits include a clogged air filter, a faulty thermostat, blocked vents, a damaged motor, or a dirty flame sensor. If your furnace is frequently turning on and then off in quick bursts, then you might be dealing with short cycling which is often the result of an incorrectly sized furnace, an overheated system, or some of the same issues detailed above.

However, a furnace that keeps turning off or short cycling is not the only potential problem you could face with your heating system. 

Common Furnace Problems:


  • Worn blower belt and bearings
  • Cracked or damaged heat exchanger
  • Faulty limit switch
  • Malfunctioning pilot light or ignition 
  • Damaged capacitor
  • Neglected maintenance
  • General wear-and-tear

If you are experiencing any of the above problems, you should reach out to the qualified Alexandria furnace repair pros at Air Treatment Company. We can help identify and resolve these issues before they become more severe, resulting in further damage.
