When your Knoxville air conditioner starts malfunctioning unexpectedly, it can be a cause for concern. It can be difficult to know when to call your local HVAC company. Here are the following air conditioning repair issues you may encounter:

1. Clogged Air Filter

A filthy filter obstructs airflow and can make your AC freeze up. Dirt from the filter can get into your AC and damage sensitive parts. Your air conditioner will overwork if it has to push cool air through a clogged filter. The constant stress on the system can, over time, make the motor overheat and cause damage to the compressor. Eventually, the ongoing strain will reduce the lifespan of the unit.

2. Spotty AC Maintenance

Numerous studies show that poor AC maintenance is responsible for up to 95 percent of air conditioning repairs. Leaks, electrical problems, operational issues, faulty thermostats, weak airflow and poor performance are all likely outcomes without seasonal tune-ups. Poorly maintained air conditioners are energy hogs. They require more repairs, and their service lives are short.

3. Blocked Drain Line

The condensate line drains the moisture that your air conditioner removes from indoor air. That line can get clogged with dirt and algae. Water can back up into your system, and the cooling coil could freeze up. An obstructed drain line can cause corrosion, mold, mildew, puddles on the floor and serious property damage. It can also create a fire hazard if leaking water splashes on the electrical components

4. Leaking Refrigerant

Puddles around your air conditioner can also mean a refrigerant leak. Without refrigerant, your air conditioner can’t cool your home. Airflow may be negligible. The unit might freeze up, and a frozen cooling coil could damage the compressor.
