Air Conditioning

Should I have regular preventative maintenance on my unit?
Yes.  Professional maintenance goes beyond what a typical homeowner is equipped to deal with, including things like checking your refrigerant level and cleaning the evaporator coil.  Having a professional examine your air conditioner once or twice a year will also help catch problems while they’re still small and manageable.
Indoor Humidity

The optimum indoor range is around 35% relative humidity, but 30% to 40% tends to work best for many homes. If you go above this level, condensation on the windows can occur, breeding mold that leads to allergy and respiratory problems.

Dust mites, the leading cause of allergies, thrive in as little as 50% relative humidity. Allergens like molds thrive in relative humidity conditions above 60%, leading to a variety of aliments including asthma, allergies and respiratory infections.

Too little humidity can lead to dry nose and throat, dry skin, and static electricity, which can also ruin electronic devices such as computers, VCR’s, and DVD players.

Maintaining proper and consistent humidity is also important for the wood inside your home; flooring, doors, and even pianos can shrink, crack, and warp if not properly humidified.

How do I maximize my air conditioner’s energy efficiency?
There are several ways to increase the efficiency of your air conditioner, including leaving all air vents unblocked, installing a programmable thermostat, doing regular maintenance on your system, and using ceiling fans to help keep rooms feeling cooler so you can comfortably turn the thermostat up.
