The Best Ways 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 limited air circulation from an extremely filthy filter. Unclean filters lower indoor air quality, make the home less comfortable, and can result in frozen indoor coils, ultimately leading to severe repairs.

2. Switch Shut off

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

3. Tripped Breaker

One of the most common causes of no-cool calls is a tripped breaker. Something is causing the breaker to trip. Frequently, 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 efficiency falls and electrical power use rises. Your air conditioner may 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 won't start. The switch might break; a voltage spike might cause a malfunction, and so on.

6. Blocked Drain Line

Air conditioners pull wetness out of damp air while reducing the temperature. The moisture is usually 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 individually, as needed.

7. Contactor

A contactor is an electromechanical switch in your air conditioner. Sometimes the silver coating on a contactor will use off and the contactor will stick, triggering the outdoors system to run continually, which is pricey. We inspect these as part of a spring tune-up, clean the surface of the contactors if needed, and recommend replacement if failure appears imminent.

8. Unclean Evaporator Coil

The evaporator coil lies inside your house ... Occasionally the coil has to be cleaned or dust and dirt build up will restrict the coil's heat transfer capabilities and lower system air circulation. Unclean coils increase running expense and decrease the comfort of your home. * Cool Care Heating and Air Lexington SC Should be done by HVAC Specialist

9. Unclean Condenser Coil

The condenser coil is the outdoors part of your air conditioning system. A restricted or unclean coil mishandles, increasing electrical energy use and decreasing system cooling capacity. Keeping it clean will go along way in lowering 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 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 minimize the amount of air that could be conditioning the rooms you want to condition. This triggers longer run times and greater energy expenses. Inefficient ductwork (your air distribution system) is a major 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 really cooling and the cause is restricted air flow from an extremely unclean filter. Some heating and air conditioning systems have a wall switch at the indoor system for safety and convenience that can be puzzled with a light switch. Air conditioners pull wetness out of humid air while lowering the temperature. 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 location you want 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 might be conditioning the rooms you want to condition.
