If you have a 1" non reusable filter, it ought to be changed monthly. It runs out sight and out of mind, so it's easy to forget to alter it. Yet, every year we go on service calls where the air conditioner isn't really cooling and the cause is restricted air flow from a very unclean filter. Dirty filters decrease indoor air quality, make the house less comfy, and can result in frozen indoor coils, eventually resulting in severe repair work.
2. Switch Shut off
Some heating and a/c systems have a wall switch at the indoor system for safety and convenience that can be confused with a light switch. If this is inadvertently turned off or ended throughout mild weather, your air conditioner will not start. Always inspect the condition of this switch prior to calling us.
3. Tripped Breaker
Among the most typical causes of no-cool calls is a tripped breaker. Reset it before calling us. Hopefully, it will not duplicate. Call us if it does. Something is causing the breaker to trip. Frequently, it's something easy, like a bad breaker, loose wire, or a bad capacitor. If not resolved, some basic issues could lead to far more expensive repairs.
4. Refrigerant Leaks
An air conditioning system is a sealed system. It ought to never leak refrigerant. Bad things take place when it does. Your air conditioner performance falls and electrical energy use rises. Your air conditioner may not cool. The coil may freeze. The compressor could become harmed. Plus, refrigerants are greenhouse gases. We utilize a range of tools to locate refrigerant leakages. Typically the problem is as simple as a bad Schrader valve or a weakened connection between fitting and refrigerant tubing.
Some thermostats need to 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. What goes wrong? The switch might break; a voltage spike might cause a malfunction, and so on.
6. Blocked Drain Line
A/c pull wetness from damp air while decreasing the temperature level. The wetness is normally drained pipes from your house through your pipes system. A drain pan need to exist as a back up with a secondary condensate drain. Algae can grow in these lines, obstructing them up. This can cause water damage in your house. We clear the drain lines as part of our spring cooling tune-up or you can have it done independently, as required.
A contactor is an electromechanical switch in your air conditioner. Often the silver finish on a contactor will diminish and the contactor will stick, causing the outdoors system to run continuously, which is pricey. Often ants are brought in to the electrical energy and get compressed in between the contactors, obstructing them from closing. When this takes place, the outdoors system will not run. Contactors can also fail electrically. We check these as part of a spring tune-up, clean the surface of the contactors if needed, and recommend replacement if failure appears imminent.
8. Dirty Evaporator Air Conditioning Repair Lexington SC Coil
The evaporator coil is located inside your home ... Periodically the coil has to be cleaned up or dust and dirt develop will limit the coil's heat transfer capabilities and decrease system air flow. Dirty coils increase operating cost and lower the convenience of your house. * Must be done by HEATING AND COOLING Expert
9. Filthy Condenser Coil
The condenser coil is the outside portion of your air conditioning system. A dirty or restricted coil mishandles, increasing electrical energy use and minimizing 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. If the ductwork that supply's this air lies outside of the area you want conditioned like basement, crawl space or attic has leaks, you are paying to condition a space that you do not wish to condition and lower the quantity of air that could be conditioning the rooms you want to condition. This causes longer run times and greater energy costs. Ineffective ductwork (your air distribution system) is a major energy waster in most homes. I will have more on this in future articles.
