How to Prevent A/c Breakdowns This Summer Season



If you have a 1" disposable filter, it ought to be changed monthly. It runs out sight and out of mind, so it's easy to forget to alter it. Yet, every year we go on service calls where the air conditioner isn't really cooling and the cause is restricted air circulation from an exceptionally dirty filter. Dirty filters decrease indoor air quality, make the house less comfy, and can result in frozen indoor coils, ultimately causing serious repair work.

2. Change Turned Off

Some heating and a/c 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 start if this is accidentally switched off or left off throughout moderate weather. Always inspect the condition of this switch prior to calling us.

3. Tripped Breaker

One of the most common causes of no-cool calls is a tripped breaker. Reset it prior to calling us. Ideally, it won't repeat. Call us if it does. Something is triggering the breaker to journey. Often, it's something easy, like a bad breaker, loose wire, or a bad capacitor. Nevertheless, if not addressed, some simple problems might cause far more costly repair work.

4. Refrigerant Leaks

An air conditioning system is a sealed system. It ought to never ever leakage refrigerant. When it does, bad things take place. Your air conditioner efficiency falls and electrical power usage increases. Your air conditioner may not cool. The coil may freeze. The compressor could become harmed. Plus, refrigerants are greenhouse gases. We utilize a range of tools to track down refrigerant leaks. Frequently the issue is as basic as a bad Schrader valve or a weakened connection in between fitting and refrigerant tubing.

5. Thermostat

Some thermostats must be switched between heating mode and cooling mode. If the switch remains in the incorrect position or breaks, your air conditioner will not start. Quality digital thermostats hardly ever stop working. Some of the cheap ones available from the big boxes might. So what goes wrong? The switch may break; a voltage spike may trigger a breakdown, and so on.

6. Obstructed Drain Line

Air conditioning unit pull moisture out of damp air while reducing the temperature level. The wetness is usually drained pipes from your home through your plumbing system. ac repair A drain pan should be present 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 home. 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. In some cases the silver covering on a contactor will subside and the contactor will stick, triggering the outdoors system to run continually, which is costly. Often ants are brought in to the electrical energy and get compressed in between the contactors, obstructing them from closing. The outdoors system won't run when this happens. 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 imminent.

8. Filthy Evaporator Coil

The evaporator coil lies inside your house ... Regularly the coil needs to be cleaned 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 comfort of your home. * Should be done by HVAC Specialist

9. Unclean Condenser Coil

The condenser coil is the outdoors part of your air conditioning system. A restricted or dirty coil is inefficient, increasing electricity usage and reducing system cooling capacity. Keeping it tidy will go along method lowering energy expenses and minimizing the wear and tear on your a/c system.

10. Duct Leaks

With a forced air heating & cooling system you pay to condition air. The ductwork provides the air to the various rooms. 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 an area that you do not wish to condition and minimize the amount of air that could be conditioning the rooms you want to condition. This causes longer run times and higher energy costs. Ineffective ductwork (your air circulation system) is a significant energy waster in a lot of houses. I will have more on this in future short articles.


Every year we go on service calls where the air conditioner isn't really cooling and the cause is limited air flow from an extremely dirty filter. Some heating and air conditioning systems have a wall switch at the indoor system for security and benefit that can be confused with a light switch. Air conditioners pull moisture out of humid 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 situated outside of the location you desire conditioned like basement, crawl space or attic has leaks, you are paying to condition an area that you do not desire to condition and minimize the amount of air that could be conditioning the rooms you desire to condition.
