Claim This BusinessMiddleton Heating & Sheet Metal, Inc. has kept Corvallis residents warm since 1949, making it one of the Willamette Valley's longest-operating heating contractors. The family-owned business holds Oregon CCB license number 336, meaning it was only the 336th contractor in the state to register for licensing, a distinction that speaks to its longevity in a field where many companies come and go. With a 4.3-star rating drawn from 49 customer reviews, Middleton balances a heritage spanning more than seven decades with modern HVAC solutions for the Mid-Valley region.
What sets Middleton apart is its in-house sheet metal fabrication department, which has operated continuously since 1949 and handles both custom orders and repairs. As an authorized Lennox dealer, the company installs and services the full range of Lennox furnaces, air conditioners, and heat pumps, including the S40 smart thermostat. Customers also note the team's willingness to service other brands, Fujitsu ductless heat pumps, older systems dating to 1975, and competitor installations that other contractors declined to touch.
Customer stories from the reviews reveal technicians who go beyond standard calls. During a July heat wave with temperatures exceeding 100 degrees, Middleton installers completed a furnace, air conditioner, and water heater replacement in two days flat. Technician Mark earned particular praise for diagnosing a system's performance issues and explaining options to homeowners, while another technician Ian installed a Lennox S40 thermostat and fielded several maintenance questions. One reviewer noted technicians Cody and Cheyenne provided real-time progress updates during a heat pump installation, even helping with a roof vent cover on the same day.
All nine visible reviews award 5 stars, with customers specifically praising competitive bidding, same-day service during extreme heat, and technicians who explain repair options thoroughly. Reviewers name individual team members, Ian, Mark, Cody, Cheyenne, Brett, in ways that suggest consistent, identifiable service quality across calls.
