If you have a 1" non reusable filter, it must be changed monthly. It's out of sight and out of mind, so it's simple to forget to change it. Every year we go on service calls where the air conditioner isn't cooling and the cause is restricted air circulation from an exceptionally dirty filter. Filthy filters minimize indoor air quality, make the house less comfortable, and can result in frozen indoor coils, ultimately causing serious repair work.
2. Switch Shut off
Some heating and cooling systems have a wall switch at the indoor unit for safety and convenience that can be puzzled with a light switch. Your air conditioner will not begin if this is accidentally switched off or left off throughout moderate weather. Always inspect the condition of this switch prior to calling us.
3. Tripped Breaker
One of the most common causes of no-cool calls is a tripped breaker. Reset it prior to calling us. Ideally, it won't repeat. Call us if it does. Something is triggering the breaker to journey. Often, it's something easy, like a bad breaker, loose wire, or a bad capacitor. Nevertheless, if not addressed, some simple issues might cause far more costly repair work.
4. Refrigerant Leaks
An a/c system is a sealed system. It must never ever leakage refrigerant. When it does, bad things happen. Your air conditioner effectiveness falls and electrical energy use rises. 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 find refrigerant leakages. Typically the problem is as simple as a bad Schrader valve or a weakened connection between refrigerant and fitting tubing.
Some thermostats should be changed in between heating mode and cooling mode. If the switch is in the wrong position or breaks, your air conditioner won't start. Quality digital thermostats hardly ever stop working. A few of the cheap ones available from the big boxes might. So what goes wrong? The switch may break; a voltage spike may trigger a malfunction, and so on.
6. Clogged Drain Line
Ac system pull moisture out of humid air while reducing the temperature level. The wetness is usually drained pipes from your house through your pipes system. A drain pan need to be present as a back up with a secondary condensate drain. Algae can grow in these lines, clogging them up. This can lead to 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 required.
A contactor is an electromechanical switch in your air conditioner. Sometimes the silver coating on a contactor will wear away 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, blocking them from closing. When this happens, the outdoors system will not run. Contactors can likewise stop working electrically. We inspect these as part of a spring tune-up, clean the surface of the contactors if needed, and suggest replacement if failure appears imminent.
8. Unclean Evaporator Coil
The evaporator coil lies inside your house ... Regularly the coil needs 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 minimize the comfort of your home. * Ought to be done by HVAC Professional
9. Dirty Condenser Coil
The condenser coil is the outside part of your air conditioning system. A unclean or limited coil mishandles, increasing electrical power usage and reducing system cooling capacity. Keeping it tidy will go along method lowering energy expenses and minimizing 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 rooms. If the ductwork that supply's this air is located outside of the location you desire conditioned like basement, crawl space or attic has leakages, you are paying to condition an area that you do not want to condition and decrease the amount of air that could be conditioning the rooms you want to condition. This triggers longer run times and greater energy expenses. Inefficient ductwork (your air distribution system) is a major energy waster in most houses. I will have more on this in future posts.
Every year we go on service Lexington SC air conditioning repair calls where the air conditioner isn't cooling and the cause is limited air circulation from an incredibly dirty filter. Some heating and air conditioning systems have a wall switch at the indoor unit for security and benefit that can be puzzled with a light switch. Air conditioners pull moisture out of humid air while lowering the temperature level. 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 leakages, 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.
