Every year we go on service calls where the air conditioner isn't really cooling and the cause is limited air flow from an incredibly filthy filter. Dirty filters reduce indoor air quality, make the home less comfortable, and can result in frozen indoor coils, ultimately leading to severe repairs.
2. Switch Turned Off
Some heating and a/c systems have a wall switch at the indoor unit for security and benefit that can be puzzled with a light switch. Your air conditioner will not begin if this is inadvertently switched off or left off throughout mild weather. Constantly inspect 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 trip. Often, it's something basic, like a bad breaker, loose wire, or a bad capacitor.
4. Refrigerant Leaks
An air conditioning system is a sealed system. Your air conditioner performance falls and electrical energy usage rises. Your air conditioner may not cool.
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 begin. Quality digital thermostats rarely fail. Some of the inexpensive ones readily available from the huge boxes might. What goes incorrect? The switch may break; a voltage spike may cause a malfunction, and so on.
6. Clogged Drain Line
Air conditioners pull moisture out of humid air while reducing the temperature. The moisture is generally 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 individually, as needed.
A contactor is an electromechanical switch in your air conditioner. In some cases the silver finishing on a contactor will wear off and the contactor will stick, triggering the outside unit to run continuously, which is expensive. 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. Unclean Evaporator Coil
The evaporator coil lies inside your house ... Regularly the coil has to be cleaned up or dust and dirt build up will restrict the coil's heat transfer abilities and reduce system air flow. Filthy coils increase running expense and reduce the convenience of your house. * Need to be done by HVAC Expert
9. Dirty Condenser Coil
The condenser coil is the outdoors portion of your air conditioning system. A limited or filthy coil is inefficient, increasing electrical power usage and lowering system cooling capacity. Keeping it tidy will go along way in lowering energy costs and lowering the wear and tear on air conditioning Lexington SC your a/c system.
10. Duct Leaks
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 location you desire conditioned like basement, crawl space or attic has leakages, you are paying to condition a space that you do not desire to condition and decrease the quantity of air that could be conditioning the spaces you desire to condition. Inefficient ductwork (your air circulation system) is a major energy waster in a lot of homes.
Every year we go on service calls where the air conditioner isn't cooling and the cause is limited air circulation from an extremely filthy filter. Some heating and air conditioning systems have a wall switch at the indoor unit for safety and benefit that can be confused with a light switch. Air conditioners pull wetness out of humid air while reducing 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 location you want conditioned like basement, crawl space or attic has leakages, you are paying to condition an area that you do not want to condition and decrease the quantity of air that might be conditioning the spaces you want to condition.
