How to Prevent Cooling Breakdowns This Summer Season



Every year we go on service calls where the air conditioner isn't really cooling and the cause is limited air circulation from an extremely dirty filter. Filthy filters lower indoor air quality, make the home less comfortable, and can result in frozen indoor coils, ultimately leading to serious repairs.

2. Switch Shut off

Some heating and cooling systems have a wall switch at the indoor system for safety and convenience that can be puzzled with a light switch. If this is mistakenly switched off or left off during moderate weather condition, your air conditioner will not start. Always inspect the condition of this switch prior to calling us.

3. Tripped Breaker

One of the most typical causes of no-cool calls is a tripped breaker. Something is causing the breaker to trip. Frequently, it's something basic, like a bad breaker, loose wire, or a bad capacitor.

4. Refrigerant Leaks

An air conditioning system is a sealed system. Your air conditioner efficiency falls and electrical power use increases. Your air conditioner might not cool.

5. Thermostat

Some thermostats need to be changed in between heating mode and cooling mode. Your air conditioner won't begin if the switch is in the incorrect position or breaks. Quality digital thermostats seldom stop working. A few of the low-cost ones readily available from the huge boxes might. So what goes wrong? The switch might break; a voltage spike might cause a breakdown, and so on.

6. Clogged Drain Line

Air conditioners pull moisture out of humid air while lowering the temperature level. The wetness is normally drained out of your home through your plumbing system. We clear the drain lines as part of our spring air conditioning tune-up or you can have it done separately, as needed.

7. Contactor

A contactor is an electromechanical switch in your air conditioner. Sometimes the silver covering on a contactor will subside and the contactor will stick, causing the outside unit to run continuously, which is expensive. In some cases ants are attracted to the electricity and get squashed between the contactors, blocking them from closing. The outdoors system will not run when this occurs. Contactors can likewise stop working electrically. We inspect these as part of a spring tune-up, tidy the surface of the contactors if needed, and suggest replacement if failure appears imminent.

8. Dirty Evaporator Coil

The evaporator coil is located inside your home ... Periodically the coil needs to be cleaned or dust and dirt build up will limit the coil's heat transfer abilities and lower system air circulation. Unclean coils increase running expense and decrease the comfort of your home. * Should be done by HVAC Professional

9. Unclean Condenser Coil

The condenser coil is the outdoors part of your air conditioning system. A restricted or dirty coil is inefficient, increasing electricity use and lowering system cooling capability. Keeping it tidy will go along method minimizing energy expenses and decreasing 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 spaces. If the ductwork that supply's this air lies beyond the area you want conditioned like basement, crawl space or attic has leaks, you are paying to condition an area that you do not wish to condition and decrease the amount of air that could be conditioning the spaces you wish to condition. This triggers longer run times and greater energy bills. Inefficient ductwork (your air distribution system) is a ac repair significant energy waster in the majority of houses. I will have more on this in future short articles.


Every year we go on service calls where the air conditioner isn't cooling and the cause is restricted air circulation from an exceptionally filthy filter. Some heating and air conditioning systems have a wall switch at the indoor unit for safety and benefit that can be puzzled with a light switch. Air conditioners pull wetness out of humid air while lowering the temperature level. With a forced air heating & cooling system you pay to condition air. If the ductwork that supply's this air is situated outside of the area you want conditioned like basement, crawl area or attic has leakages, you are paying to condition an area that you do not want to condition and lower the quantity of air that could be conditioning the rooms you desire to condition.
