If you have a 1" disposable filter, it must be replaced monthly. It's out of sight and from mind, so it's simple to forget to change it. Yet, every year we go on service calls where the air conditioner isn't cooling and the cause is limited air circulation from an extremely filthy filter. Unclean filters reduce indoor air quality, make the home less comfy, and can result in frozen indoor coils, ultimately resulting in serious repair work.
2. Change Turned Off
Some heating and a/c systems have a wall switch at the indoor system for security and convenience 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
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 easy, like a bad breaker, loose wire, or a bad capacitor.
4. Refrigerant Leaks
A cooling system is a sealed system. It needs to never leak refrigerant. Bad things occur when it does. Your air conditioner performance falls and electricity use rises. Your air conditioner might not cool. The coil might freeze. The compressor might become damaged. Plus, refrigerants are greenhouse gases. We use a variety of tools to find refrigerant leakages. Typically the problem is as simple as a bad Schrader valve or a weakened connection between refrigerant and fitting tubing.
5. Thermostat
Some thermostats should be switched in between heating mode and cooling mode. Your air conditioner won't begin if the switch is in the wrong position or breaks. Quality digital thermostats hardly ever stop working. Some of the low-cost ones offered from the big boxes might. What goes wrong? The switch may break; a voltage spike might trigger a malfunction, and so on.
6. Blocked Drain Line
Air conditioners pull moisture out of damp air while reducing the temperature level. The moisture is usually drained out of your home through your pipes system. We clear the drain lines as part of our spring air conditioning tune-up or you can have it done separately, as required.
7. Contactor
A contactor is an electromechanical switch in your air conditioner. In some cases the silver coating on a contactor will subside and the contactor will stick, causing the outside system to run constantly, which is expensive. Often ants are drawn in to the electrical energy and get squashed in between the contactors, obstructing them from closing. When this occurs, the outdoors unit won't run. Contactors can also stop working air conditioning Lexington SC electrically. We check these as part of a spring tune-up, tidy the surface area of the contactors if needed, and suggest replacement if failure appears impending.
8. Unclean Evaporator Coil
The evaporator coil is located inside your house ... Periodically the coil has to be cleaned up or dust and dirt build up will limit the coil's heat transfer capabilities and minimize system air circulation. Filthy coils increase running cost and lower the comfort of your home. * Need to be done by A/C Professional
9. Dirty Condenser Coil
The condenser coil is the outside part of your air conditioning system. A unclean or limited coil is inefficient, increasing electrical power usage and reducing system cooling capability. Keeping it tidy will go along method minimizing energy expenses 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 situated outside of the location you want 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 could be conditioning the spaces you desire to condition. Inefficient ductwork (your air distribution system) is a major energy waster in the majority of houses.
Every year we go on service calls where the air conditioner isn't really 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 puzzled with a light switch. Air conditioners pull wetness out of damp air while reducing 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 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 minimize the amount of air that could be conditioning the spaces you desire to condition.
