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 unclean filter. Unclean filters decrease indoor air quality, make the house less comfy, and can result in frozen indoor coils, eventually leading to major repair work.
2. Switch Turned Off
Some heating and a/c systems have a wall switch at the indoor system for safety and convenience that can be puzzled with a light switch. If this is mistakenly switched off or left off throughout mild weather, your air conditioner will not begin. Constantly examine the condition of this switch before calling us.
3. Tripped Breaker
One of the most typical reasons for no-cool calls is a tripped breaker. Reset it before calling us. Hopefully, it will not duplicate. If it does, call us. Something is causing the breaker to journey. Typically, it's something basic, like a bad breaker, loose wire, or a bad capacitor. If not addressed, some simple problems could lead to far more costly repair work.
4. Refrigerant Leaks
A cooling system is a sealed system. It should never leakage refrigerant. When it does, bad things take place. Your air conditioner efficiency falls and electrical power usage increases. Your air conditioner might not cool. The coil may freeze. The compressor could become harmed. Plus, refrigerants are greenhouse gases. We utilize a range of tools to track down refrigerant leaks. Frequently the issue is as basic as a bad Schrader valve or a weakened connection between fitting and refrigerant tubing.
5. Thermostat
Some thermostats must be switched in between heating mode and cooling mode. If the switch remains in the incorrect position or breaks, your air conditioner won't start. Quality digital thermostats hardly ever stop working. A few of the cheap ones offered from the big boxes might. So what goes wrong? The switch might break; a voltage spike may trigger a breakdown, and so on.
6. Obstructed Drain Line
Air conditioning unit pull moisture out of humid air while reducing the temperature level. The wetness is usually drained pipes from your house through your plumbing system. A drain pan should be present as a back up with a secondary condensate drain. Algae can grow in these lines, blocking them up. This can result in water damage in your house. We clear the drain lines as part of our spring a/c tune-up or you can have it done independently, as required.
7. Contactor
A contactor is an electromechanical switch in your air conditioner. In some cases the silver finishing on a contactor will disappear and the contactor will stick, triggering the outdoors system to run continually, which is pricey. Often ants are brought in to the electrical energy and get compressed in between the contactors, obstructing them from closing. The outdoors system will not run when this occurs. Contactors can likewise stop working electrically. We inspect these as part of a spring tune-up, clean the surface of Lexington SC air conditioning repair the contactors if needed, and recommend replacement if failure appears imminent.
8. Dirty Evaporator Coil
The evaporator coil is located inside your house ... Occasionally the coil has to be cleaned up or dust and dirt build up will restrict the coil's heat transfer capabilities and reduce system air circulation. Unclean coils increase running expense and decrease the comfort of your home. * Should be done by HVAC Specialist
9. Unclean Condenser Coil
The condenser coil is the outdoors part of your air conditioning system. A restricted or dirty coil is inefficient, increasing electricity usage and reducing system cooling capability. Keeping it tidy will go along method lowering energy expenses and minimizing the wear and tear on your a/c system.
10. Duct Leaks
With a forced air heating & cooling system you pay to condition air. The ductwork provides the air to the various rooms. 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 minimize the amount of air that could be conditioning the rooms you wish to condition. This triggers longer run times and greater energy expenses. Ineffective ductwork (your air distribution system) is a major energy waster in most homes. I will have more on this in future articles.
Every year we go on service calls where the air conditioner isn't cooling and the cause is restricted air circulation from an exceptionally filthy filter. Some heating and air conditioning systems have a wall switch at the indoor unit for safety and convenience that can be puzzled with a light switch. Air conditioners pull wetness out of humid air while lowering the temperature level. With a forced air heating & cooling system you pay to condition air. If the ductwork that supply's this air is situated 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 desire to condition and decrease the amount of air that could be conditioning the spaces you desire to condition.
