Common Summer AC Problems and Their Solutions

Living in the North texas means living in summer heat that often surpasses 100 degrees. With high temperatures outside, keeping cool inside your home is essential. But, sometimes, high outdoor temperatures cause your HVAC systems to strain, leading to system breakdowns. Unfortunately, many homeowners experience issues with their comfort system during the hottest months of the year, leaving you extremely uncomfortable inside your home. Read on for common summer AC problems and their solutions.

The Unit Won’t Stay on

If your comfort system turns on, only to switch off, your system may be short-cycling, which could be an easy fix. If it’s caused by something like dirty condenser coils, evaporator coils, or air filters, all you need to do is a little maintenance.  It can also be cased by a drain line that is clogged up.  There is an emergency float switch installed on most cooling systems to automatically shut down a system that is not draining  properly. This is done to protect from water draining through a ceiling or damaging a home.   These conditions should indicate the need for immediate maintenance, and give us a call to check your entire system and determine what the causing  the system to cycle off.  (Maintenance Agreements with 2 two ups per year, will generally prevent these situations from happening.)


Frozen Unit

If your comfort system is blowing warm air, or not blowing any air at all, it could be due to frozen evaporator coils. If the air around the evaporator coils gets too cold in humid outdoor conditions, ice can form on the coils.  This ice can also be located on the outside coil or the Freon  lines both outside the unit or on the inside unit.  If you suspect frozen evaporator coils, or see any ice present on your system,  turn the entire system off, leave it off until all the ice melts.  Give our offices a call to check your system to determine the best course of action to repair your system.  Common Causes of frozen up systems can be, dirty filters, poor air flow in your coils both on the inside unit or the outside unit, freon leaks in your system.  These are closed systems, they should never leak or require large amounts of Freon to be added or removed.  Over time and age and weather, coil leaks can occur, causing Freon loss.  Those leaks can be identified and repaired in some cases.   Low charged or over charged systems can also cause ice build up.  (Maintenance Agreements with 2 two ups per year, will generally prevent these situations from happening.)

Noisy AC System

If there is more noise than usual coming from any portion of your comfort system, it’s best to call in the professionals at ProTemp DFW. Our technicians are trained to locate the source of the problem and can usually have it fixed in the same day. A noisy comfort system could be caused by a buildup of dust and debris that’s putting unnecessary pressure on your system’s components. Loud noises could also indicate damaged outdoor equipment or refrigerant leaks. All of the scenarios are best handled by an experienced professional.

Damaged Ductwork

If your comfort system is working hard but your home is still warm, it could be due to damaged ductwork. If there are any holes in your air ducts, the cool air your system is producing won’t fully make it into your house. This wastes energy and forces your comfort system to work overtime trying to cool your home. This unnecessary strain could lead to premature system failure or the need for costly emergency repairs. summer AC problems

Ductwork is very fragile and can be easily installed incorrectly if the technician is inexperienced or unsure of what he or she is doing. Call in the professionals at ProTemp DFW to ensure your ductwork is installed correctly and efficiently. You’ll save money and hassle in the short run and the long run.

Low Insulation

If your home’s insulation is over 10 years old, it has likely settled and been moved around to the point where it isn’t effective anymore. Without proper insulation, your comfort system will continue struggling to cool your home. If your attic insulation is looking flat, ProTemp DFW can help. Our technicians are happy to measure your insulation levels and give a free estimate for any insulation that is needed.
