How to Prevent Cooling Breakdowns This Summer



Every year we go on service calls where the air conditioner isn't really cooling and the cause is limited air flow from an incredibly filthy filter. Unclean filters decrease indoor air quality, make the house less comfy, and can result in frozen indoor coils, eventually leading to serious repair work.

2. Change Switched off

Some heating and air conditioning systems have a wall switch at the indoor system for security and convenience that can be confused with a light switch. If this is inadvertently turned off or left off during mild weather condition, your air conditioner will not begin. Always 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 triggering 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 electricity use rises. Your air conditioner may not cool.

5. Thermostat

Some thermostats must 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. Clogged Drain Line

Air conditioners pull moisture out of humid air while reducing the temperature. The wetness is usually 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 independently, as required.

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 system to run continually, 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 impending.

8. Filthy Evaporator Coil

The evaporator coil is located inside your home ... Periodically the coil needs to be cleaned up or dust and dirt develop will limit the coil's heat transfer capabilities and decrease system air flow. Dirty coils increase operating expense and lower the convenience of your house. * Must be done by HEATING AND COOLING Expert

9. Filthy Condenser Coil

The condenser coil is the outside portion of your air conditioning system. A dirty or restricted coil mishandles, increasing electrical Cool Care Heating and Air Lexington SC energy use and minimizing system cooling capability. Keeping it tidy will go along way in decreasing 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 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 a space that you do not wish to condition and lower the quantity of air that could be conditioning the spaces you want to condition. This causes longer run times and higher energy costs. Ineffective ductwork (your air circulation system) is a significant energy waster in many 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 an exceptionally filthy filter. Some heating and air conditioning systems have a wall switch at the indoor unit for safety and convenience that can be puzzled with a light switch. Air conditioners pull wetness out of damp air while reducing the temperature. 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 location you desire conditioned like basement, crawl area or attic has leaks, you are paying to condition a space that you do not desire to condition and lower the quantity of air that could be conditioning the rooms you want to condition.
