How to Prevent Cooling Breakdowns This Summer Season



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 reduce indoor air quality, make the home less comfortable, and can result in frozen indoor coils, ultimately leading to severe repairs.

2. Switch Shut off

Some heating and cooling systems have a wall switch at the indoor system for safety 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 begin. Constantly examine 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 causing the breaker to trip. Frequently, it's something basic, like a bad breaker, loose wire, or a bad capacitor.

4. Refrigerant Leaks

An air conditioning system is a sealed system. It should never ever leak refrigerant. Bad things take place when it does. Your air conditioner performance falls and electrical energy use rises. Your air conditioner may not cool. The coil may freeze. The compressor could become damaged. 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. If the switch is in the wrong position or breaks, your air conditioner won't start. 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 cause a breakdown, and so on.

6. Obstructed Drain Line

Air conditioning unit pull moisture out of humid air while lowering the temperature. The moisture is generally drained from your house through your pipes system. A drain pan ought to exist 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 a/c tune-up or you can have it done individually, as required.

7. Contactor

A contactor is an electromechanical switch in your air conditioner. Often the silver finish on a contactor will use off and the contactor will stick, triggering the outdoors system to run constantly, which is costly. We inspect 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 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 house. * Need to be done by A/C Specialist

9. Unclean Condenser Coil

The condenser coil is the outdoors part of your air conditioning system. A filthy or restricted coil mishandles, increasing ac repair electrical energy use and minimizing system cooling capacity. Keeping it clean will go along way in reducing energy costs and reducing 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 provides the air to the various spaces. If the ductwork that supply's this air lies outside of the area you desire conditioned like basement, crawl space or attic has leakages, you are paying to condition an area that you do not want to condition and reduce the quantity of air that could be conditioning the spaces you wish to condition. This causes longer run times and higher energy bills. Inefficient ductwork (your air distribution system) is a major energy waster in a lot of houses. 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 unclean 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 humid 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 situated outside of the location you desire conditioned like basement, crawl area or attic has leakages, you are paying to condition an area that you do not desire to condition and reduce the amount of air that could be conditioning the rooms you want to condition.
