How to Prevent A/c Breakdowns This Summer Season



Every year we go on service calls where the air conditioner isn't really cooling and the cause is restricted air flow from a very dirty filter. Dirty filters minimize indoor air quality, make the house less comfy, and can result in frozen indoor coils, eventually leading to major repair work.

2. Change Turned Off

Some heating and a/c systems have a wall switch at the indoor system for safety and convenience that can be confused with a light switch. Your air conditioner will not start if this is mistakenly switched off or left off during mild weather condition. Constantly check the condition of this switch before calling us.

3. Tripped Breaker

One of the most common causes of no-cool calls is a tripped breaker. Reset it prior to calling us. Ideally, it won't repeat. If it does, call us. Something is triggering the breaker to journey. Often, it's something easy, like a bad breaker, loose wire, or a bad capacitor. Nevertheless, if not dealt with, some easy issues could lead to far more costly repair work.

4. Refrigerant Leaks

An air conditioning system is a sealed system. It ought to never leakage refrigerant. When it does, bad things take place. Your air conditioner efficiency falls and electrical power usage increases. Your air conditioner might not cool. The coil may freeze. The compressor could become harmed. Plus, refrigerants are greenhouse gases. We utilize a variety of tools to track down refrigerant leaks. Frequently the issue is as basic as a bad Schrader valve or a weakened connection in between fitting and refrigerant tubing.

5. Thermostat

Some thermostats must be switched between heating mode and cooling mode. If the switch is in the incorrect position or breaks, your air conditioner will not begin. The switch may break; a voltage spike may trigger a breakdown, and so on.

6. Clogged Drain Line

Air conditioners pull wetness out of damp air while decreasing the temperature level. The wetness is normally drained out of your house through your pipes system. We clear the drain lines as part of our spring air conditioning tune-up or you can have it done independently, as needed.

7. Contactor

A contactor is an electromechanical switch in your air conditioner. Sometimes the silver coating on a contactor will wear away and the contactor will stick, causing the outside unit to run constantly, which is costly. In some cases ants are drawn in to the electrical power and get squashed between the contactors, blocking them from closing. When this occurs, the outside unit won't run. Contactors can also fail electrically. We examine these as part of a spring tune-up, tidy the surface area of the contactors if required, and advise replacement if failure appears impending.

8. Dirty Evaporator Coil

The evaporator coil is located inside your house ... Occasionally the coil has to be cleaned up or dust and dirt build up will restrict the coil's heat transfer capabilities and decrease system air flow. Dirty coils increase operating expense and lower the convenience of your home. * Ought to be done by HVAC Professional

9. Unclean Condenser Coil

The condenser coil is the outdoors part of your air conditioning system. A unclean or limited coil is inefficient, increasing electricity usage and reducing system cooling capability. Keeping it tidy will go along method minimizing energy expenses and minimizing the wear and tear on your a/c system.

10. Duct Leaks

With a forced air heating & cooling system you pay to condition air. The ductwork delivers the air to the different rooms. If the ductwork that supply's this air lies beyond the location you desire conditioned like basement, crawl space or attic has leakages, you are paying to condition a space that you do not want to condition and reduce the quantity of air that could be conditioning the spaces you wish to condition. This triggers longer run times and higher energy bills. Inefficient ductwork (your air distribution system) is a significant energy waster in a lot of homes. I will have more on this in future short articles.


Every year we go on service calls where the air conditioner isn't really cooling and the cause is ac repair limited air circulation from an incredibly dirty filter. Some heating and air conditioning systems have a wall switch at the indoor system for security and convenience that can be confused with a light switch. Air conditioners pull moisture out of damp air while decreasing the temperature level. With a forced air heating & cooling system you pay to condition air. If the ductwork that supply's this air is located outside of the area you desire conditioned like basement, crawl area or attic has leaks, you are paying to condition a space that you do not desire to condition and lower the quantity of air that could be conditioning the rooms you desire to condition.
