About Colonial Heating & Cooling
Colonial Heating & Cooling has earned a 4.8-star average across 4,683 Google reviews, making it one of the most reviewed and highest-rated HVAC contractors in the Plymouth area. Located in Plymouth, Michigan, the company operates from 8 AM to 10 PM every day, including weekends, a schedule that reflects their commitment to availability for emergency calls. Homeowners throughout the region turn to Colonial when furnaces fail during Michigan winters or AC units quit during summer heat waves, trusting the volume of positive feedback as proof of consistent service.
What distinguishes Colonial Heating & Cooling is their expertise with uncommon equipment and their DTE Energy partnership. One reviewer specifically noted the team's ability to diagnose and repair a Lennox heat pump, a system the customer described as not very common these days, demonstrating technical competency beyond standard installations. The company also handles humidifier repairs with improved drainage solutions, and their office staff walks customers through repair options and upgrade possibilities, including chimney code compliance work.
Reviewers consistently name the technicians who solve their problems. Ronnie arrived early for his appointment and resolved a furnace issue in under 20 minutes. Brandon P responded within two hours of a DTE service request and had a replacement part already en route. The installation team, Mike, Alberto, Shawn, Nick, and Dell, earned praise for their efficiency and for keeping the worksite clean before and after a full system replacement. These named encounters illustrate why thousands of customers have left five-star reviews.
