How to Avoid Air Conditioning Breakdowns This Summertime



If you have a 1" non reusable filter, it ought to be changed monthly. It runs out sight and out of mind, so it's easy to forget to alter it. Every year we go on service calls where the air conditioner isn't really cooling and the cause is restricted air flow from an exceptionally dirty filter. Dirty filters minimize indoor air quality, make the house less comfortable, and can lead to frozen indoor coils, ultimately resulting in major repairs.

2. Switch Switched off

Some heating and cooling systems have a wall switch at the indoor unit for safety and benefit 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 inspect the condition of this switch prior to calling us.

3. Tripped Breaker

Among the most typical causes of no-cool calls is a tripped breaker. Reset it before calling us. Hopefully, it won't repeat. If it does, call us. Something is triggering the breaker to journey. Often, it's something simple, like a bad breaker, loose wire, or a bad capacitor. If not attended to, some easy problems might lead to far more pricey repairs.

4. Refrigerant Leaks

An air conditioning system is a sealed system. Your air conditioner effectiveness falls and electrical power usage increases. Your air conditioner might not cool.

5. Thermostat

Some thermostats must be switched between heating mode and cooling mode. Your air conditioner won't start if the switch is in the wrong position or breaks. Quality digital thermostats seldom stop working. A few of the low-cost ones readily available from the huge boxes might. What goes wrong? The switch might break; a voltage spike might trigger a breakdown, and so on.

6. Obstructed Drain Line

Air conditioners pull moisture out of humid air while reducing the temperature level. The wetness is normally drained pipes from your house through your pipes system. A drain pan need to exist as a back up with a secondary condensate drain. Algae can grow in these lines, clogging them up. This can cause 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. In some cases the silver covering on a contactor will subside and the contactor will stick, triggering the outside system to run constantly, which is pricey. In some cases ants are drawn in to the electrical energy and get compressed in between the contactors, obstructing them from closing. The outdoors unit won't run when this occurs. Contactors can also stop working electrically. We check these as part of a Cool Care Heating and Air Lexington SC spring tune-up, tidy 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 up or dust and dirt develop will restrict the coil's heat transfer capabilities and decrease system air flow. Dirty coils increase operating cost and reduce the comfort of your home. * Should be done by HEATING AND COOLING Expert

9. Dirty Condenser Coil

The condenser coil is the outdoors portion of your air conditioning system. A filthy or restricted coil is inefficient, increasing electricity usage and reducing system cooling capacity. Keeping it tidy will go along way in reducing energy costs and reducing 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 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 reduce the quantity of air that might be conditioning the rooms you desire to condition. Ineffective ductwork (your air distribution system) is a major energy waster in most houses.


Every year we go on service calls where the air conditioner isn't really cooling and the cause is limited air flow from an exceptionally unclean filter. 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. Air conditioners pull wetness out of damp air while decreasing the temperature level. 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 area 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 lower the quantity of air that might be conditioning the rooms you want to condition.
