Every year we go on service calls where the air conditioner isn't really cooling and the cause is limited air flow from a very unclean filter. Dirty filters decrease indoor air quality, make the house less comfortable, and can result in frozen indoor coils, eventually leading to major repair work.
2. Switch Shut off
Some heating and cooling systems have a wall switch at the indoor unit for safety and benefit that can be puzzled with a light switch. If this is unintentionally turned off or ended during mild weather condition, your air conditioner will not begin. Always inspect the condition of this switch prior to calling us.
3. Tripped Breaker
Among the most common causes of no-cool calls is a tripped breaker. Reset it before calling us. Ideally, it will not repeat. If it does, call us. Something is triggering the breaker to journey. Often, it's something simple, like a bad breaker, loose wire, or a bad capacitor. If not dealt with, some easy issues might lead to far more expensive repairs.
4. Refrigerant Leaks
An air conditioning system is a sealed system. Your air conditioner efficiency falls and electrical power usage increases. Your air conditioner might not cool.
5. Thermostat
Some thermostats should be changed in between heating mode and cooling mode. If the switch is in the incorrect position or breaks, your air conditioner won't start. The switch might break; a voltage spike might trigger a breakdown, and so on.
6. Obstructed Drain Line
Air conditioners pull wetness out of damp air while decreasing the temperature level. The wetness is normally drained pipes 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.
7. Contactor
A contactor is an electromechanical switch in your air conditioner. Often the silver finish on a contactor will use off and the contactor will stick, triggering the outdoors system to run continually, which is costly. We inspect 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 Coil
The evaporator coil lies inside your house ... Occasionally the coil has to be cleaned up or Cool Care Heating and Air Lexington SC dust and dirt develop will restrict the coil's heat transfer capabilities and decrease system air flow. Dirty coils increase operating expense 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 limited or unclean 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 rooms. If the ductwork that supply's this air is located outside of the area you desire 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 want to condition. This causes longer run times and greater energy costs. Ineffective ductwork (your air circulation system) is a major energy waster in many 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 flow from an exceptionally unclean filter. 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. Air conditioners pull moisture out of damp 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 area you desire conditioned like basement, crawl area or attic has leakages, you are paying to condition a space that you do not want to condition and reduce the quantity of air that might be conditioning the rooms you want to condition.
