Ways To Avoid Air Conditioning Breakdowns This Summertime



If you have a 1" disposable filter, it must be changed monthly. It's out of sight and out of mind, so it's simple to forget to change it. Yet, every year we go on service calls where the air conditioner isn't really cooling and the cause is restricted air flow from a very filthy filter. Unclean filters reduce indoor air quality, make the house less comfy, and can result in frozen indoor coils, eventually resulting in severe repairs.

2. Change Turned Off

Some heating and a/c 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 ended during mild weather, your air conditioner will not start. 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. Ideally, it will not duplicate. Call us if it does. Something is causing the breaker to trip. Frequently, it's something easy, like a bad breaker, loose wire, or a bad capacitor. If not addressed, some easy problems might lead to far more costly repair work.

4. Refrigerant Leaks

An a/c system is a sealed system. It needs to never ever leak refrigerant. Bad things occur when it does. Your air conditioner performance falls and electrical energy usage increases. Your air conditioner may not cool. The coil may freeze. The compressor might end up being harmed. Plus, refrigerants are greenhouse gases. We utilize a range of tools to locate 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 must be switched between heating mode and cooling mode. Your air conditioner will not begin if the switch is in the incorrect position or breaks. Quality digital thermostats hardly ever stop working. A few of the cheap ones available from the big boxes might. What goes wrong? The switch might break; a voltage spike might cause a breakdown, and so on.

6. Clogged Drain Line

Air conditioners pull moisture out of damp air while lowering the temperature. The moisture is typically drained out of your home through your plumbing system. We clear the drain lines as part of our spring air conditioning tune-up or you can have it done separately, as needed.

7. Contactor

A contactor is an electromechanical switch in your air conditioner. Sometimes the silver covering on a contactor will wear away and the contactor will stick, causing the outside unit to run continuously, which is expensive. Sometimes ants are attracted to the electrical power and get squashed between the contactors, obstructing them from closing. When this occurs, the outdoors system will not run. Contactors can also fail electrically. We check these as part of a spring tune-up, clean the surface of the contactors if needed, and recommend replacement if failure appears impending.

8. Unclean Evaporator Coil

The evaporator coil lies inside your house ... Occasionally the coil has to be cleaned up or dust and dirt build up will restrict the coil's heat transfer capabilities and decrease system air flow. Dirty coils increase operating cost and reduce the convenience of your house. * Must be done by A/C 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 energy use and minimizing system cooling capacity. Keeping it clean will go along way in reducing energy costs and lowering the wear and tear on your cooling 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 location you want conditioned like basement, crawl space 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 could be conditioning the spaces you wish to condition. This causes longer run times and higher energy bills. Ineffective ductwork (your air distribution system) is a major energy waster in most homes. I will have more on this in future posts.


Every year we go on service calls where the air conditioner isn't really cooling and the cause is limited Cool Care Heating and Air Lexington SC air circulation from an incredibly dirty filter. Some heating and air conditioning systems have a wall switch at the indoor unit for security and benefit that can be puzzled with a light switch. Air conditioners pull moisture 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 want conditioned like basement, crawl area or attic has leakages, 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.
