Every year we go on service calls where the air conditioner isn't really cooling and the cause is limited air circulation from a very unclean filter. Dirty filters decrease indoor air quality, make the house less comfy, and can result in frozen indoor coils, ultimately leading to serious repairs.
2. Switch Turned Off
Some heating and air conditioning systems have a wall switch at the indoor system for safety and convenience that can be confused with a light switch. If this is mistakenly turned off or left off during moderate weather, your air conditioner will not start. Constantly check the condition of this switch before calling us.
3. Tripped Breaker
One of the most typical causes of no-cool calls is a tripped breaker. Something is triggering the breaker to journey. Often, it's something simple, 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 leak refrigerant. Bad things occur when it does. Your air conditioner effectiveness falls and electrical energy usage increases. Your air conditioner may not cool. The coil might freeze. The compressor might end up being damaged. Plus, refrigerants are greenhouse gases. We use a variety of tools to track down refrigerant leaks. Frequently the issue is as basic as a bad Schrader valve or a weakened connection in between refrigerant and fitting tubing.
5. Thermostat
Some thermostats should be changed in between heating mode and cooling mode. Your air conditioner won't start if the switch is in the wrong position or breaks. Quality digital thermostats rarely fail. Some of the cheap ones available from the big boxes might. So what goes wrong? The switch might break; a voltage spike might cause a malfunction, and so on.
6. Clogged Drain Line
Air conditioning unit pull moisture out of humid air while decreasing the temperature. The wetness is normally drained pipes from your house through your pipes system. A drain pan must 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 home. 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. Often the silver covering on a contactor will wear off and the contactor will stick, triggering the outdoors unit to run continuously, which is pricey. We inspect these as part of a spring tune-up, clean the surface of the contactors if required, and recommend replacement if failure appears impending.
8. Dirty Evaporator Coil
The evaporator coil lies inside your house ... Regularly the coil needs to be cleaned up or dust and dirt build up will restrict the coil's heat transfer abilities and minimize system air flow. Unclean coils increase running cost and reduce the convenience of your home. * Should be done by A/C Expert
9. Dirty Condenser Coil
The condenser coil is the outdoors portion of your air conditioning system. A unclean or limited coil is inefficient, Cool Care Heating and Air Lexington SC increasing electricity use and decreasing system cooling capability. Keeping it tidy will go along way in decreasing energy costs and lowering 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 different spaces. If the ductwork that supply's this air is located beyond the area you desire conditioned like basement, crawl space or attic has leaks, you are paying to condition a space that you do not wish to condition and reduce the quantity of air that could be conditioning the rooms you wish to condition. This causes longer run times and greater energy expenses. Inefficient ductwork (your air circulation system) is a major energy waster in a lot of homes. I will have more on this in future posts.
Every year we go on service calls where the air conditioner isn't really cooling and the cause is restricted air circulation from an incredibly unclean filter. Some heating and air conditioning systems have a wall switch at the indoor unit for security and convenience that can be puzzled with a light switch. Air conditioners pull moisture out of damp air while decreasing the temperature. 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 area you desire conditioned like basement, crawl space or attic has leaks, you are paying to condition an area that you do not want to condition and lower the amount of air that might be conditioning the spaces you want to condition.
