How to Prevent Air Conditioning Breakdowns August

In today's rough economic times the last thing you need is a surprise air conditioning repair. While all mechanical systems require repairs every so often, many are preventable. In no particular order, here are the ten most common problems we come across every spring as well as what you can do to avoid them.

1. Dirty Filter

For those who have a 1" disposable filter, it must be replaced monthly. It's beyond sight and from mind, so it's very easy to forget to change it. Yet, yearly we go on service calls in which the air conditioner isn't cooling along with the cause is restricted ventilation from an extremely dirty filter. Dirty filters reduce indoor quality of air, make the home less comfortable, and may result in frozen indoor coils, eventually bringing about serious repairs.

2. Switch Powered down

Some heating and air conditioning systems have a wall switch at the indoor unit for safety and convenience that may be confused with a light switch. If this is accidentally switched off or left off during mild weather, your air conditioning equipment will not start. Make sure the condition of this switch before calling us.

3. Tripped Breaker

One of the most common causes of no-cool calls can be a tripped breaker. Reset it before calling us. Hopefully, it's not going to repeat. If it does, call us. Something is causing the breaker to trip. Often, it is something simple, like a bad breaker, loose wire, or even a bad capacitor. However, or else addressed, some simple problems could lead to far more expensive repairs.

4. Refrigerant Leaks

A cloak conditioning system is an enclosed system. It should never leak refrigerant. When it does, bad unexpected things happen. Your air conditioner efficiency falls and electricity use rises. Your air conditioning equipment may not cool. The coil may freeze. The compressor may be damaged. Plus, refrigerants are greenhouse gases. We make use of a variety of tools to acquire refrigerant leaks. Often the dilemma is as simple as a bad Schrader valve or a weakened connection between fitting and refrigerant tubing.

5. Thermostat

Some thermostats has to be switched between heating mode and cooling mode. In the event the switch is in the wrong position or breaks, your air conditioning unit won't start. Quality digital thermostats rarely fail. A number of the cheap ones available from the big boxes might. Precisely what goes wrong? The switch might break; a voltage spike could cause a malfunction, etc.

6. Clogged Drain Line

Air conditioning pull moisture away from humid air while reducing the temperature. The moisture is normally drained out of your home through your plumbing system. A drain pan should be present as a back up with a secondary condensate drain. Algae can grow of these lines, clogging them up. This leads to water damage in your home. We remove the drain lines included in our spring air-con tune-up or you can have it done separately, if required.

7. Contactor

A contactor is an electromechanical switch in your air conditioning equipment. Sometimes the silver coating on the contactor will wear off along with the contactor will stick, resulting in the outside unit to operate continuously, which is expensive. Sometimes ants are fascinated by the electricity and get squashed relating to the contactors, blocking them from closing. When this occurs, the outside unit won't run. Contactors also can fail electrically. We check these included in a spring tune-up, clean the top of the contactors if needed, and recommend replacement if failure appears imminent.

8. Dirty Evaporator Coil

The evaporator coil is located inside your home... Periodically the coil has to be cleaned or dust and dirt build up will restrict the coil's heat transfer capabilities and lower system air flow. Dirty coils increase operating cost minimizing the comfort of your home. * Ought to be done by HVAC Professional

9. Dirty Condenser Coil

The condenser coil may be the outside portion of your air conditioning system. A dirty or restricted coil is inefficient, increasing electricity usage and reducing system cooling capacity. Keeping it clean will go along way in reducing energy costs and minimizing the wear and tear on your air conditioning system.

10. Duct Leaks

Having a forced air heating & cooling system you pay to condition air. The ductwork provides the air to the different rooms. If your ductwork that supply's this air is situated outside of the area you want conditioned like basement, crawl space or attic has leaks, you're paying to condition a place that you do not want to condition minimizing the amount of air that is conditioning the rooms you need to condition. This causes longer run times and energy bills. Inefficient ductwork (your air distribution system) can be a major energy waster in many homes. I will have an overabundance on this in future articles.
