The Best Ways To Prevent Air Conditioning Breakdowns This Summertime



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

2. Switch Shut off

Some heating and a/c systems have a wall switch at the indoor unit for security and benefit that can be confused with a light switch. If this is unintentionally turned off or ended during mild weather, your air conditioner will not begin. Constantly check the condition of this switch before 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. Often, it's something easy, like a bad breaker, loose wire, or a bad capacitor.

4. Refrigerant Leaks

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

5. Thermostat

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

6. Obstructed Drain Line

Air conditioners pull moisture out of humid air while lowering the temperature. The moisture is generally 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. Often the silver finish on a contactor will use off and the contactor will stick, triggering the outdoors system to Cool Care Heating and Air Lexington SC run continually, which is costly. We inspect these as part of a spring tune-up, clean the surface of the contactors if needed, and recommend replacement if failure appears impending.

8. Unclean Evaporator Coil

The evaporator coil lies inside your house ... Regularly the coil needs to be cleaned or dust and dirt build up will restrict the coil's heat transfer abilities and lower system air circulation. Filthy coils increase operating cost and decrease the comfort of your home. * Need to be done by A/C Specialist

9. Filthy Condenser Coil

The condenser coil is the outside portion of your air conditioning system. A limited or unclean coil mishandles, increasing electrical power usage and reducing system cooling capacity. Keeping it tidy will go along method minimizing energy costs and decreasing the wear and tear on your air conditioning system.

10. Duct Leaks

With a forced air heating & cooling system you pay to condition air. The ductwork delivers the air to the various spaces. If the ductwork that supply's this air lies outside of the area you want conditioned like basement, crawl space or attic has leakages, you are paying to condition an area that you do not want to condition and decrease the amount 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 circulation system) is a significant energy waster in a lot of homes. I will have more on this in future articles.


Every year we go on service calls where the air conditioner isn't cooling and the cause is restricted air circulation from a very filthy filter. Some heating and air conditioning systems have a wall switch at the indoor unit for security and benefit that can be puzzled with a light switch. Air conditioners pull moisture out of humid 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 want conditioned like basement, crawl area or attic has leaks, you are paying to condition a space that you do not desire to condition and reduce the quantity of air that might be conditioning the rooms you want to condition.
