Costly Air Conditioning Repair Bills Can Be Prevented

In today’s rough economic times the last thing you need is a surprise air conditioning repair. While all mechanical systems require repairs from time to time, many are preventable. In no particular order, here are the ten most common problems we encounter every spring and what you can do to avoid them.

1. Dirty Filter

Every year we go on service calls where the air conditioner isn’t cooling and the cause is restricted air flow from an extremely dirty filter. Dirty filters reduce indoor air quality, make the home less comfortable, and can result in frozen indoor coils, eventually leading to serious repairs.

2. Switch Turned Off

Some heating and air conditioning systems have a wall switch at the indoor unit for safety and convenience that can be confused with a light switch. Your air conditioner will not start if this is accidentally switched off or left off during mild weather. Always check the condition of this switch before calling us.

3. Tripped Breaker

One of the most common causes of no-cool calls is a tripped breaker. Reset it before calling us. Often, it’s something simple, like a bad breaker, loose wire, or a bad capacitor.

 

4. Refrigerant Leaks

An air conditioning system is a sealed system. Your air conditioner efficiency falls and electricity use rises. Your air conditioner may not cool.

 

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. The switch might break; a voltage spike might cause a malfunction, and so on.

6. Clogged Drain Line

Air conditioners pull moisture out of humid 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 coating on a contactor will wear off and the contactor will stick, causing the outside unit to run continuously, which is expensive. 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. Dirty Evaporator Coil

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

9. Dirty Condenser Coil

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