When homeowners want to test their indoor air quality in Colonia, NJ, they call Sam's Air Control HVAC company. Our team offers air quality testing, which the Environmental Protection Agency (EPA) advises doing every other year. This is primarily because radon, a colorless, odorless, tasteless gas, can appear suddenly. Radon is the second-leading cause of lung cancer in the U.S. and is found in about 10% of homes in New Jersey.
