Every year we go on service calls where the air conditioner isn't really cooling and the cause is restricted air flow from an incredibly filthy filter. Unclean filters lower indoor air quality, make the home less comfortable, and can result in frozen indoor coils, ultimately leading to severe repair work.
2. Switch Shut off
Some heating and a/c systems have a wall switch at the indoor system for security and convenience that can be confused with a light switch. Your air conditioner will not begin if this is mistakenly changed off or left off during mild weather. Constantly examine the condition of this switch prior to calling us.
3. Tripped Breaker
One of the most typical causes of no-cool calls is a tripped breaker. Something is causing the breaker to journey. Often, it's something easy, like a bad breaker, loose wire, or a bad capacitor.
4. Refrigerant Leaks
An a/c system is a sealed system. It must never ever leakage refrigerant. When it does, bad things happen. Your air conditioner effectiveness falls and electrical power usage increases. Your air conditioner may not cool. The coil may freeze. The compressor could become damaged. Plus, refrigerants are greenhouse gases. We use a range of tools to locate refrigerant leakages. Often the problem is as simple as a bad Schrader valve or a weakened connection between fitting and refrigerant tubing.
Some thermostats must be switched between heating mode and cooling mode. Your air conditioner will not begin if the switch is in the incorrect position or breaks. Quality digital thermostats hardly ever stop working. Some of the cheap ones available from the big boxes might. So what fails? The switch may break; a voltage spike may trigger a breakdown, and so on.
6. Blocked Drain Line
Air conditioners pull wetness out of damp air while decreasing the temperature level. The wetness is usually drained pipes out of your house through your pipes system. We clear the drain lines as part of our spring air conditioning tune-up or you can have it done independently, as required.
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 system to run continually, which is pricey. We examine these as part of a spring tune-up, tidy the surface area of the contactors if required, and advise replacement if failure appears impending.
8. Filthy 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 lower system air circulation. Unclean coils increase running expense and minimize the comfort of your home. * Ought to be done by HEATING AND COOLING Expert
9. Filthy Condenser Coil
The condenser coil is the outside portion of your air conditioning system. A limited or unclean coil mishandles, increasing electrical power use and decreasing system cooling capacity. Keeping it clean will go along way in reducing energy expenses and lowering 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 provides the air to the various spaces. ac repair If the ductwork that supply's this air is located outside of the area you want conditioned like basement, crawl space or attic has leakages, you are paying to condition an area that you do not wish to condition and decrease the amount of air that could be conditioning the rooms you wish to condition. This triggers longer run times and greater energy expenses. Inefficient ductwork (your air distribution system) is a major energy waster in the majority of houses. I will have more on this in future posts.
Every year we go on service calls where the air conditioner isn't cooling and the cause is restricted air flow from an exceptionally unclean filter. Some heating and air conditioning systems have a wall switch at the indoor system for security and convenience that can be confused with a light switch. Air conditioners pull moisture out of damp 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 located outside of the area you desire conditioned like basement, crawl area or attic has leaks, you are paying to condition a space that you do not desire to condition and minimize the quantity of air that could be conditioning the rooms you desire to condition.
