Mast Heating & Cooling

Mast Heating & Cooling has kept West Michigan comfortable since 1956, making it one of the oldest continuously operating HVAC contractors in the Ottawa and Allegan County region. Based in Zeeland, the company holds a 4.9-star rating from 345 reviews, a volume of feedback that speaks to sustained quality over nearly seven decades. Their service area spans over 40 communities including Grand Rapids, Holland, Grand Haven, and Zeeland itself, with 24/7 emergency availability for both residential and commercial clients. The company reports completing over 800 installations and 3,000 annual maintenance visits, plus more than 7,500 comfort restoration projects.

What distinguishes Mast from regional competitors is their dual expertise in both traditional residential HVAC and marine systems, a relatively rare combination in West Michigan. Their website confirms Trane as a carried brand, and customer reviews reference both Trane air conditioning and heat pump installations. The company also offers radiant heating services including heated driveways, a niche that requires specialized equipment and training. This diversification beyond standard furnace and AC work positions them as a single source for both conventional and innovative climate solutions.

Customer reviews reveal specific technicians who have earned strong praise. Justin handled an emergency furnace no-heat call in February, arriving the same morning and restoring warmth by noon, a response time reviewers specifically called out. For a commercial project on a 55,000 square foot building, Jim Potter and his team worked through sub-zero temperatures with minimal disruption to operations. Another reviewer noted their willingness to handle a challenging mobile home furnace replacement that other contractors declined, with follow-up service when a thermostat issue emerged post-install.
