Heating and Cooling for Hazel Green Homes
Hazel Green has newer subdivisions alongside older homes and country properties, so we see everything from new heat pumps to older furnaces and packaged units. Each setup has its own maintenance needs, and we know what to check on all of them.
Winter cold snaps are when a heat pump leans hardest on its backup heat and a furnace runs its longest cycles. A tune-up in early fall helps make sure your system is ready before the first hard freeze.

Local Notes for Hazel Green
Hazel Green was settled in the early 1800s, when farmers from Georgia, Tennessee and the Carolinas came for its rich soil, and it was briefly incorporated in 1821. One story says the name comes from hazelnut bushes that turned a bright green each spring. Today farmland is giving way to new subdivisions, and Hazel Green High School serves students from here and Meridianville.
Permits in Hazel Green
Hazel Green is not incorporated, so permits for homes here come from the Madison County Building Inspection Department. The county requires a permit to install or replace a heating or cooling system. When your job needs one, we file it and schedule the inspection.
Nearby, we also serve Meridianville, New Market, Huntsville, Harvest and Toney.

Hazel Green HVAC FAQs
My heat pump has ice on it. Is that normal?
A light layer of frost in cold, damp weather is normal, and the defrost cycle should clear it. If the whole unit stays covered in ice for hours, call us. Do not chip the ice off, since that can damage the coil.
When should I schedule a heating tune-up?
Early fall is best, before the first cold night. That gives time to fix anything we find before you need the heat.
Do you service packaged units?
Yes. We repair, maintain and replace packaged units, along with split systems, heat pumps and furnaces.
Does Hazel Green require a permit for a new HVAC system?
Yes. Hazel Green is in unincorporated Madison County, and the county Building Inspection Department permits new and replacement heating and cooling systems. We handle the permit and inspection.
