Common AC Problem: Inadequate Cooling

September 26, 2018

During the summer, your air conditioner (AC) works harder and longer. That high demand may cause a problem to rear its ugly head.  In this multi-part post, we’ll take a look at some of the most common AC problems, talk about the possible causes, and provide suggestions for tackling each problem.

Inadequate Cooling

If your system is working fine (no leaks or noises, etc.), but it is not able to maintain the desired temperature you set on the thermostat, especially during the hottest part of the day, it could be that your unit is under-sized for your house. Perhaps you added space on to the house since it was built or removed trees near the house that were providing shade. When excessive demand is being made on the unit and it can’t keep up, you may need a larger unit. To delay having to get another system, you can add extra insulation – especially in the attic – and get double or triple paned windows with low E glass, to help improve your system’s performance. Getting regular tune-ups in spring and fall also helps to maintain your system’s efficiency so it will operate at peak performance. Other reasons for inadequate cooling include:

  • A dirty condenser or evaporator coil
  • A blocked condenser
  • Clogged drain lines
  • A lack of system refrigerant

Avoid AC Problems

Summer can be the best time of the year, so don’t let air conditioning problems hinder you from enjoying it.  Be sure to get annual AC maintenance visits, so it will run efficiently and be ready for the high demand of the summer’s heat.  If you live in the Nashville area and experience any heating or cooling problems, call on Interstate AC Service at (615) 832-8500.
