How to Avoid Cooling Breakdowns This Summer



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. Filthy filters minimize indoor air quality, make the house less comfortable, and can result in frozen indoor coils, eventually leading to major repair work.

2. Switch Shut off

Some heating and cooling systems have a wall switch at the indoor system for safety and convenience that can be puzzled with a light switch. Your air conditioner will not begin if this is mistakenly switched off or left off throughout moderate weather condition. Always inspect the condition of this switch prior to calling us.

3. Tripped Breaker

Among the most common causes of no-cool calls is a tripped breaker. Reset it prior to calling us. Ideally, it won't repeat. If it does, call us. Something is triggering the breaker to journey. Typically, it's something simple, like a bad breaker, loose wire, or a bad capacitor. If not dealt with, some easy issues might lead to far more expensive repairs.

4. Refrigerant Leaks

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

5. Thermostat

Some thermostats must be switched in between heating mode and cooling mode. Your air conditioner won't start 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 incorrect? The switch may break; a voltage spike may trigger a malfunction, and so on.

6. Blocked Drain Line

Air conditioners pull wetness out of damp air while decreasing 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. Often the silver coating on a contactor will wear off and the contactor will stick, triggering the outdoors unit to run continually, which is expensive. We inspect these as part of a spring tune-up, clean the surface of the contactors if required, and suggest replacement if failure appears impending.

8. Unclean Evaporator Coil

The evaporator coil is located inside your house ... Periodically the coil has to be cleaned or dust and dirt build up will limit the coil's heat transfer capabilities and minimize system air flow. Filthy coils increase running cost and decrease the convenience of your home. * Must be done by A/C Professional

9. Filthy Condenser Coil

The condenser coil is the outside portion of your air conditioning system. A filthy or limited coil mishandles, increasing electricity usage and minimizing system cooling capability. Keeping it clean will go along method lowering energy costs and decreasing 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 various spaces. If the ductwork that supply's this air is located outside of the area you desire conditioned like basement, crawl space or attic has leakages, you are paying to condition a space that you do not want to condition and minimize the quantity of air that could be conditioning the rooms you want to condition. This triggers longer run times and greater energy costs. Inefficient ductwork (your air distribution system) is a major energy waster in many houses. I will have more on this in future posts.
