ZNF Heating and Cooling

At ZNF Heating and Cooling, we specialize in heating, cooling, and geothermal work in Northern Michigan. We are licensed, insured, and EPA 608 certified, and we provide service around the clock. Our geographic focus includes Otsego, Montmorency, Charlevoix, Emmett, Kalkaska, Oscoda, and Crawford counties. We also provide free estimates for equipment replacements and new installations.

Our heating work includes furnace service, with a particular focus on Armstrong furnaces. We can also help with other furnace brands. For boiler systems, we work with both high-efficiency and cast-iron equipment, including Bosch high-efficiency boilers and Utica cast-iron boilers. We are Bosch and Utica certified and assist with boiler concerns such as water leaks, unusual smells or sounds, loss of heat, and loss of hot water.

We also provide central air-conditioning service, from routine checkups and repairs to complete system replacements. When a new system is needed, we help homeowners choose air-conditioning equipment suited to the size and needs of the home. For spaces where conventional equipment may not be the right fit, we offer LG single-zone and multi-zone mini-split systems, including options that support separate temperature zones while using limited interior space.

Our approach is based on each homeowner’s indoor-air-quality and comfort-control needs. We aim to recommend appropriate solutions rather than push equipment that is not needed, and we place importance on careful workmanship without cutting corners. Across our heating, boiler, cooling, mini-split, and geothermal work, we want our service to reflect the values we emphasize: fairness, honesty, dependability, high standards, and professional service.
