AC Repairs & Service

Air conditioners are mechanical systems with components that are subject to mechanical failure. These are the compressor, the condenser, the evaporator coil and blower, and the expansion valve or metering device. The rest of the system is mostly composed of air ducts and vents that transport hot air out of the building and disperse cold air throughout the rooms inside the structure. These ducts aren't subject to mechanical failure, but they can be problematic. If the ducts aren't sealed properly, they leak cool air, which wastes energy and can drive the price of operating your air conditioner through the roof.

The compressor is a pump that circulates the refrigerant in a loop between the condenser and the evaporator. It is the essential mechanism of heat transfer that enables the AC to supply cool air to the home or office.

The condenser transfers the unwanted heat out of the refrigerant system and into an outside medium that absorbs the heat and transfers it to a disposal point. The three types of condensers are water-cooled condensers, air-cooled condensers, and evaporative condensers, which use a mixture of air and water as the transfer medium. Most residential air conditioners have air-cooled condensers.

The evaporator coil is a subsystem of an air-and-water condenser. It is composed of a network of refrigerant-filled tubes that remove moisture and heat energy from the AC system. Evaporator coils are also called blower coils, cooling coils, or chilling units.

When an air conditioner breaks down, it's usually because one or more of these parts have failed. Our AC repair service will quickly and accurately diagnose the problem and then get to work replacing the broken part with a new one. If the compressor fails, the refrigerant will no longer circulate, so you'll just feel warm air coming out of the unit. Likewise, if the compressor coils fail, the AC will no longer be able to cool the air and will output room-temperature air, which could be very warm during the summer. If the fan fails, you won't feel anything coming out of the unit.

Another common problem that usually results in wasted money due to decreased efficiency is leaky air ducts, which allow the cool air to escape, thus wasting the energy used to cool that air. Shoring up the ducts and strengthening the insulation will fix that problem, but the strain of overproduction can damage the AC before you notice or are able to correct the problem. This wears down the AC much more quickly than a proper AC delivery system setup, so you may need to replace the AC when you discover significant leakage in the ducts. At very least, you'll probably need a new fan, condenser, or blower, and that's an AC repair we handle all the time.

If you have any questions or would like to schedule an air conditioner repair or inspection, please give us a call. One of our skilled technicians will take care of the problem and return your AC to peak performance quickly and for a reasonable price.
