How to Prevent A/c Breakdowns This Summer



Every year we go on service calls where the air conditioner isn't cooling and the cause is restricted air circulation from an extremely filthy filter. Filthy 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 convenience that can be puzzled with a light switch. If this is unintentionally turned off or ended during mild weather condition, your air conditioner will not begin. Constantly examine the condition of this switch before calling us.

3. Tripped Breaker

One of the most common reasons for no-cool calls is a tripped breaker. Reset it prior to calling us. Hopefully, it won't duplicate. Call us if it does. Something is triggering the breaker to trip. Often, it's something easy, like a bad breaker, loose wire, or a bad capacitor. If not addressed, some simple problems could lead to far more costly repair work.

4. Refrigerant Leaks

An a/c system is a sealed system. It must never leakage refrigerant. When it does, bad things take place. Your air conditioner performance falls and electrical energy usage rises. Your air conditioner may not cool. The coil may freeze. The compressor could become damaged. Plus, refrigerants are greenhouse gases. We use a variety of tools to track down refrigerant leaks. Often the problem is as simple as a bad Schrader valve or a weakened connection between fitting and refrigerant tubing.

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 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 damp air while decreasing the temperature level. The wetness is normally drained pipes 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 individually, as needed.

7. Contactor

A contactor is an electromechanical switch in your air conditioner. In some cases the silver covering on a contactor will wear off and the contactor will stick, triggering the outdoors unit to run constantly, which is costly. We check these as part of a spring tune-up, tidy the surface area of the contactors if needed, and advise replacement if failure appears imminent.

8. Unclean Evaporator Coil

The evaporator coil is located inside your house ... Periodically the coil has to be cleaned or dust and dirt develop will limit the coil's heat transfer capabilities and lower system air flow. Unclean coils increase operating expense and reduce the convenience of your home. * Must be done by A/C Professional

9. Filthy Condenser Coil

The condenser coil is the outdoors portion of your air conditioning system. A restricted or unclean coil is inefficient, increasing electrical energy usage and lowering system cooling capacity. Keeping it tidy will go along way in lowering energy costs and lowering the wear and tear on your a/c system.

10. Duct Leaks

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 desire conditioned like basement, crawl space or attic has leakages, you are paying to condition a space that you do not desire to condition and decrease the quantity of air that might be conditioning the rooms you desire to condition. Inefficient ductwork (your air circulation system) is a major energy waster in a lot of homes.


Every year we go on service calls where the air conditioner isn't really cooling and the cause is restricted air circulation from an incredibly unclean filter. Some heating and air conditioning systems have a wall switch at the air conditioning Lexington SC indoor unit for security and convenience that can be confused with a light switch. Air conditioners pull wetness out of damp air while reducing 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 desire conditioned like basement, crawl area or attic has leakages, you are paying to condition a space that you do not want to condition and reduce the amount of air that might be conditioning the rooms you desire to condition.
