Mr. Furnace

What Mr. Furnace does

Mr. Furnace is a privately held residential and commercial HVAC service company headquartered in Saint Clair Shores, Michigan, founded in 1983 by Anthony Contrera. The company employs 11-50 people and serves Macomb, Oakland, and Wayne counties across more than 20 cities in Southeast Michigan. Its core offering spans the full HVAC lifecycle — installation, repair, and maintenance of furnaces, air conditioners, heat pumps, boilers, ductless mini-splits, air handlers, water heaters, thermostats, and indoor air quality systems including duct cleaning, humidification, dehumidification, and air purification. The technology layer is non-proprietary: Mr. Furnace installs and services third-party equipment from manufacturers including Trane (as Michigan's premier Trane Comfort Specialist), Carrier, Lennox, American Standard, Bryant, Honeywell, Mitsubishi, Rheem, Goodman, Daikin, and SpacePak, with a customer-facing energy savings calculator as its only in-house software asset.

The business model combines transactional revenue (per-job repair calls and installations), recurring revenue (annual maintenance programs and service agreements), and project-based commercial work (custom design, installation, and ongoing maintenance for restaurants, schools, churches, office buildings, strip malls, and retail outlets). Pricing is primarily quote-based; residential repair tickets typically range $99 to $800, while system installations carry multi-thousand-dollar ticket sizes and are supported by promotional discounts and customer financing. Go-to-market is direct-to-consumer: phone-based scheduling (1-855-MR-FURNACE), a website with online scheduling, and word-of-mouth referrals amplified by Google reviews, with 7-day operating hours and 24/7 emergency availability in select service areas. Customer-retention mechanics include a Satisfaction Guarantee, Lifetime Duct Guarantee, No Lemons Guarantee, and Comfort Guarantee, and the firm reports a 99% Trane installation satisfaction rating alongside multiple regional awards (Best of the Best 2024 Macomb Daily, 2025 Plus of the City, 2026 Best of Business Rate). The company remains founder-controlled with no disclosed outside investors, acquisitions, or funding events.
