If you have a 1" disposable filter, it must be changed monthly. It's out of sight and out of mind, so it's simple to forget to change it. Yet, 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 unclean filter. Dirty filters decrease indoor air quality, make the house less comfy, and can result in frozen indoor coils, eventually causing severe repairs.
2. Change Turned Off
Some heating and air conditioning systems have a wall switch at the indoor unit for security and benefit that can be confused with a light switch. If this is inadvertently turned off or left off 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 prior to calling us. Ideally, it will not duplicate. If it does, call us. Something is causing the breaker to trip. Typically, it's something basic, like a bad breaker, loose wire, or a bad capacitor. If not dealt with, some easy issues could lead to far more expensive repairs.
4. Refrigerant Leaks
An a/c system is a sealed system. It must never ever leakage refrigerant. Bad things happen when it does. Your air conditioner effectiveness falls and electrical energy usage increases. Your air conditioner may not cool. The coil may freeze. The compressor could become damaged. Plus, refrigerants are greenhouse gases. We use a range of tools to find refrigerant leakages. Typically the issue is as basic as a bad Schrader valve or a weakened connection in between refrigerant and fitting tubing.
Some thermostats must be switched between heating mode and cooling mode. Your air conditioner will not begin if the switch is in the incorrect position or breaks. Quality digital thermostats hardly ever stop working. A few of the low-cost ones readily 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 unit pull wetness from damp air while reducing the temperature level. The wetness is usually drained pipes from your home through your plumbing system. A drain pan ought to 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 a/c 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 covering on a contactor will subside and the contactor will stick, causing the outside unit to run continuously, which is expensive. Sometimes ants are attracted to the electricity and get squashed between the contactors, obstructing them from closing. When this takes place, the outdoors system will not run. Contactors can also stop working electrically. We examine these as part of a spring tune-up, tidy the surface area of the contactors if required, and suggest replacement if failure appears imminent.
8. Dirty Evaporator Coil
The evaporator coil is located inside your house ... Occasionally the coil has to be cleaned 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 A/C Specialist
9. Unclean Condenser Coil
The condenser coil is the outdoors portion of your air conditioning system. A dirty or restricted coil mishandles, increasing electrical power usage and reducing system cooling capacity. Keeping it tidy will go along method minimizing energy costs and decreasing the wear and tear on your air conditioning 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 area you desire conditioned like basement, crawl area or attic has leakages, you are paying to condition a space Cool Care Heating and Air Lexington SC that you do not want to condition and minimize the amount of air that could be conditioning the spaces you desire to condition. Inefficient ductwork (your air distribution system) is a significant energy waster in the majority of houses.
Every year we go on service calls where the air conditioner isn't cooling and the cause is restricted air circulation from a very filthy filter. Some heating and air conditioning systems have a wall switch at the indoor unit for safety and benefit that can be puzzled with a light switch. Air conditioners pull moisture out of humid air while decreasing 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 desire conditioned like basement, crawl space or attic has leaks, you are paying to condition an area that you do not desire to condition and decrease the amount of air that might be conditioning the rooms you want to condition.
