About National Heating & Cooling Inc
National Heating & Cooling has operated from a Grand River Avenue location in northwest Detroit for more than 60 years, which makes it the longest-tenured company in this ranking by a wide margin. It is a Carrier Factory Authorized Dealer, meaning its installers go through Carrier's own training program, and its technicians carry NATE certification alongside a Better Business Bureau rating.
The service list covers furnace repair, replacement, and maintenance, boiler service, heat pump work, central air conditioning repair and replacement, ductless mini-split systems, and indoor air quality improvements. Maintenance plans are available for customers who want scheduled seasonal checkups, and the company offers financing through Wells Fargo and Microf's rent-to-own program for customers who do not qualify for traditional financing.
Reviewer Michael Adams describes technician Ricardo troubleshooting a furnace that kept shutting off after ten minutes, calling it "another great service" after repeat visits, and reviewer Rui Chen's account, though eight years old, still describes fair pricing and a two-year labor warranty on a past job. The company's service area reaches more than 40 Michigan cities beyond Detroit, including Livonia, Farmington, Northville, Troy, and Warren.
The website offers a contact form rather than a direct email address, and specific license numbers are not published, though the Carrier authorization and NATE certification are clearly stated credentials.
National Heating & Cooling suits homeowners who value decades of local tenure and manufacturer-backed training over a newer company's marketing. It suits less well someone who wants to email the company directly rather than fill out a web form. Ask for the technician's Michigan mechanical contractor license number and confirm current warranty terms before a major installation.
