O.K. Heating & Air Conditioning

O.K. Heating & Air Conditioning has kept Warren County comfortable since 1979, earning a 3.9-star rating across 47 customer reviews. Based in McMinnville, the locally owned contractor serves Centertown, Morrison, Viola, and the surrounding Middle Tennessee communities with residential and light commercial HVAC solutions. Their team holds proper licensing, insurance, and certifications, operating Monday through Friday from 7:30 AM to 4 PM.

The company distinguishes itself as an authorized American Standard dealer, offering furnaces, heat pumps, air conditioners, ductless mini-split systems, and indoor air quality products including humidification, dehumidification, and filtration. All installation and service work carries a written guarantee, and technicians commit to meeting or exceeding applicable codes and standards. The business also provides flexible financing options, annual service agreements, and factory-backed extended warranties.

Customer reviews reveal mixed experiences worth noting. Jill Eckert describes a multi-call ordeal for loud furnace fan noise at her business, ultimately receiving the owner's cell phone after five attempts with no callback. Lonnie Frasier recounts a June 2025 visit where technician Mike added half a pound of refrigerant without resolving cooling issues, left without fixing the problem, and billed $115 for nothing. Both reviewers spent thousands with the company previously and express disappointment with how their concerns were handled.
