Hi-Temp Heating & Cooling, Inc.

Hi-Temp Heating & Cooling, Inc. operates from 2500 E M 21 Suite C in Corunna, serving Shiawassee County and the greater Mid Michigan region, including Owosso. The company holds an OSHA 10/30 certification and brings over 70 years of combined industry experience to residential and commercial customers. With a 4.1-star rating drawn from 30 client reviews, the team handles projects ranging from custom ductwork design builds to routine maintenance and emergency repairs. Their standard hours run Monday through Thursday 8 AM to 5 PM, with Friday service ending at 4 PM.

The contractor distinguishes itself through 24/7 emergency availability, a critical differentiator for Mid Michigan homeowners facing sudden heating failures during harsh winters. Their service palette includes both residential installations and commercial HVAC systems, with expertise in LEED-certified commercial projects. The company also offers integrated plumbing services, covering water heater installations and drain clearing, a convenience for homeowners seeking single-vendor solutions. This dual-trade capability reflects their positioning as a hometown heating company with broader mechanical expertise.

Customer experiences reveal mixed outcomes. Pamela Coffey praised technician Tom for same-day response during a frigid January morning, arriving within five hours of her 8:30 AM call with the necessary furnace part already stocked. Heather Papranec commended James for resolving a persistent gas leak across two service visits after an initial installation required removal and reinstallation following basement repairs. However, Heather Soper and Bobbi Fuller cited concerns: multi-week wait times without premium fees, a secondary component damaged during diagnosis, and quoted prices that exceeded alternative contractor estimates by significant margins.
