Ways 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 flow from a very unclean filter. Unclean filters lower indoor air quality, make the house less comfy, and can result in frozen indoor coils, ultimately leading to severe repair work.

2. Switch Turned Off

Some heating and air conditioning systems have a wall switch at the indoor unit for safety and convenience that can be confused with a light switch. If this is inadvertently turned off or ended throughout moderate weather, your air conditioner will not start. Always 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. Something is triggering the breaker to journey. 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 performance falls and electrical energy usage rises. Your air conditioner may not cool.

5. Thermostat

Some thermostats need to be changed in 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 cause 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. A drain pan ought to be present as a back up with a secondary condensate drain. Algae can grow in these lines, blocking them up. This can result in water damage in your house. We clear the drain lines as part of our spring cooling 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 off and the contactor will stick, causing the outside unit to run continuously, which is pricey. We examine these as part of a spring tune-up, tidy the surface area of the contactors if required, and suggest 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 minimize system air circulation. Filthy coils increase running expense and minimize 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 unclean coil mishandles, increasing electrical power use and lowering system cooling capability. Keeping it tidy will go along method minimizing energy expenses 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 different rooms. If the ductwork that supply's this air lies beyond the location you want conditioned like basement, crawl space or attic has leaks, you are paying to condition a space 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 air conditioning Lexington SC 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 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 leaks, you are paying to condition a space that you do not desire to condition and minimize the amount of air that could be conditioning the spaces you desire to condition.
