Claim This BusinessZimmer Heating & Cooling has kept Cincinnati comfortable for over 80 years, operating as a third-generation family business since 1946. Based in the Clifton area, the company holds master and journeyman licenses in both Ohio and Kentucky, maintains BBB accreditation dating back to 1977, and maintains an exceptional 4.9-star rating across 734 customer reviews. Their service territory spans the full Tristate Area, including Cincinnati, Dayton, and Northern Kentucky communities.
What distinguishes Zimmer from regional competitors is their manufacturer certifications and diversified expertise. They operate as a Carrier factory authorized dealer and hold Mitsubishi Elite Diamond Dealer status, placing them among a select network of contractors qualified to install and service high-performance ductless mini-split systems. Their team includes NATE-certified technicians and BPI-certified energy auditors capable of performing Manual-J heat load calculations, a detail that separates thorough contractors from those offering only basic sizing. The company also maintains light commercial design-build capabilities, serving small businesses beyond residential properties.
Homeowners who called Zimmer during emergencies mention specific technicians by name. Daniel H. praised Dan for performing a Manual-J calculation, only two of six companies he consulted offered this level of detail, before installing a Mitsubishi hyper-heat system with remade plenums. Kris I. noted Dan completed installation within days of quoting, while the crew took time explaining procedures in understandable terms. Peggie J. highlighted technicians Mose, Ziggy, and Sparkman for their clean work and respect for her home during a Carrier Infinity system installation.
734 customer reviews yield a 4.9-star average, with multiple five-star reviews praising technicians Dan and Sam for transparent quoting without upsell pressure. Customers consistently mention respectful property treatment and thorough cleanup, phrases appearing across both positive reviews and critical ones.
