How to Prevent Air Conditioning Breakdowns This Summer

Heating

In today's rough economic times the very last thing you need is a surprise ac repair. While all mechanical systems require repairs every now and then, many are preventable. In no particular order, allow me to share the ten most common problems we encounter every spring along with what you can do to avoid them.


Springhill

1. Dirty Filter

For those who have a 1" disposable filter, it needs to be replaced monthly. It's beyond sight and out of mind, so it's easy to forget to change it. Yet, each year we go on service calls the location where the air conditioner isn't cooling and also the cause is restricted air-flow 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 leading to serious repairs.

2. Switch Turned Off

Some heating and air conditioning systems use a wall switch at the indoor unit for safety and convenience that could be confused with a light switch. If this describes accidentally switched off or left off during mild weather, your ac 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 is a tripped breaker. Reset it before calling us. Hopefully, it won't repeat. If it does, contact us. Something is causing the breaker to trip. Often, it is something simple, like a bad breaker, loose wire, or a bad capacitor. However, if not addressed, some simple problems might lead to far more expensive repairs.

4. Refrigerant Leaks

A cloak conditioning system is a sealed system. It should never leak refrigerant. If this does, bad unexpected things happen. Your air conditioner efficiency falls and electricity use rises. Your air conditioner may not cool. The coil may freeze. The compressor turn into damaged. Plus, refrigerants are greenhouse gases. We use a variety of tools to find refrigerant leaks. Often the dilemma is as simple as a bad Schrader valve or perhaps a weakened connection between fitting and refrigerant tubing.

5. Thermostat

Some thermostats must be switched between heating mode and cooling mode. In the event the switch is in the wrong position or breaks, your ac won't start. Quality digital thermostats rarely fail. A few of the cheap ones provided by the big boxes might. What exactly goes wrong? The switch might break; a voltage spike might cause a malfunction, and the like.

6. Clogged Drain Line

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

7. Contactor

A contactor is an electromechanical switch in your ac. Sometimes the silver coating with a contactor will wear off as well as the contactor will stick, inducing the outside unit to run 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 may also fail electrically. We check these within a spring tune-up, clean the top 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 dirt and dust 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. * Should be carried out by HVAC Professional

9. Dirty Condenser Coil

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

10. Duct Leaks

Which has a forced air heating & cooling system you pay to condition air. The ductwork delivers the air to the different rooms. If your ductwork that supply's this air is located outside of the area you desire conditioned like basement, crawl space or attic has leaks, you might be paying to condition a space that you do not want to condition reducing the amount of air that might be conditioning the rooms you wish to condition. This causes longer run times and higher energy bills. Inefficient ductwork (your air distribution system) is a major energy waster generally in most homes. I will have an overabundance of on this in future articles.
