broiler / hydronics

Hydronics, in simple terms, refers to a central heating system that utilizes hot water to heat your residential or commercial location. It is the most comfortable, versatile, economical and effective heating option available. These systems are used extensively in Europe where the high cost and limited availability of fuel require owners to seek the most economical and effective heating options. The installation of hydronic heating systems is increasing dramatically in North America, as owners here realize how comfortable and cost-efficient they can be.

indoor air quality

Having a comfortable home goes way beyond temperature settings. The quality of the air inside yourhouse greatly affects your comfort and health. Tiny particles like mold, bacteria and moisture can cause serious respiratory problems, while others like pet dander, pollen and dust can be irritating. Advanced products such as air purifiers and cleaners, working together with a Lennox heating and cooling system, help reduce concentrations of allergens and other contaminants in the air.

“Everyone At Postma is very professional and offers wonderful and prompt service. They have helped us out of two jams one a plumbing emergency and today when our furnace in a rental unit broke and the temperature dropped to 49 degrees they came out right away and got us up and running… I can’t thank them enough and will turn to them again the next time we need something…”

Would definitely recommend Mark and Postma

“Had some leaking/flooding from an unknown source, Postma was able to schedule a plumber to come out the same day. Even though the plumber, Mark, was running behind with his other emergency calls after the cold snap he fit us in at the end of his day. Mark was kind, thorough and accurate in diagnosing the issue. Would definitely recommend Mark and Postma to anyone with a plumbing issue.”
