Make sure that duct work in your house is not excessively leaky. Leaks in ductwork can draw heat, humidity, dust and pollen into your house from the attic, garage, crawl space or the outside. This is where we can help by performing the duct test and blaster test. The Duct test is a blower door and blaster tests that uses pressure to determine leakage and sufficient air flow. This test shows us where your leakage is happening and weather it can be repaired or in some cases needs to be replaced.
In this case we use a volume meter to measure the air flow coming out of each supply duct. This lets us know if we need to add supply or return air ducts to even out the house.
During the air conditioning season always keep your fan switch in the auto position. The auto position dehumidifies about twice as well as the on position. Do not set the air conditioner thermostats lower than 75 degrees. At least once a year have your air conditioning system serviced by a reputable company. Always use good pleated filters. This will help protect your evaporator coil. Check return filters monthly for dirt. Impacted filters will impair adequate air flow over the evaporator coil and can cause damage.
