How to Avoid A/c Breakdowns This Summertime



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

2. Switch Turned Off

Some heating and air conditioning systems have a wall switch at the indoor unit for safety and benefit that can be puzzled with a light switch. Your air conditioner will not start if this is accidentally switched off or left off throughout moderate weather. 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 causing the breaker to trip. Typically, it's something basic, like a bad breaker, loose wire, or a bad capacitor.

4. Refrigerant Leaks

A cooling system is a sealed system. It needs to never ever leakage refrigerant. When it does, bad things occur. Your air conditioner efficiency falls and electricity usage increases. Your air conditioner may not cool. The coil might freeze. The compressor might become damaged. Plus, refrigerants are greenhouse gases. We use a variety of tools to locate refrigerant leakages. Frequently the problem is as simple as a bad Schrader valve or a weakened connection in between refrigerant and fitting tubing.

5. Thermostat

Some thermostats must be changed between heating mode and cooling mode. If the switch is in the wrong position or breaks, your air conditioner will not start. The switch might break; a voltage spike might trigger a malfunction, and so on.

6. Clogged Drain Line

Air conditioners pull wetness from humid air while decreasing the temperature level. The moisture is usually drained out of your home through your pipes system. A drain pan ought to be present as a back up with a secondary condensate drain. Algae can grow in these lines, obstructing them up. This can result in water damage in your home. We clear the drain lines as part of our spring cooling tune-up or you can have it done separately, Air Conditioning Repair Lexington SC as required.

7. Contactor

A contactor is an electromechanical switch in your air conditioner. Often the silver covering on a contactor will use off and the contactor will stick, causing the outdoors unit to run continuously, which is costly. We check these as part of a spring tune-up, tidy the surface of the contactors if required, and recommend replacement if failure appears impending.

8. Dirty Evaporator Coil

The evaporator coil lies inside your house ... Regularly the coil needs to be cleaned up or dust and dirt build up will limit the coil's heat transfer abilities and minimize system air circulation.

9. Filthy Condenser Coil

The condenser coil is the outside portion of your air conditioning system. A limited or dirty coil mishandles, increasing electrical energy use and reducing system cooling capability. Keeping it tidy will go along way in lowering energy costs and minimizing 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 provides the air to the different rooms. If the ductwork that supply's this air lies outside of the location 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 minimize the amount of air that could be conditioning the rooms you wish to condition. This causes longer run times and higher energy expenses. Inefficient ductwork (your air circulation system) is a major energy waster in many houses. I will have more on this in future articles.


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 dirty filter. Some heating and air conditioning systems have a wall switch at the indoor unit for safety and benefit that can be puzzled with a light switch. Air conditioners pull wetness out of damp 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 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 want to condition and decrease the amount of air that might be conditioning the spaces you desire to condition.
