"I contracted with Grant Heating & Cooling Inc. to install HVAC system in my home in the spring of 2024. They were very professional and did a very good job. In the winter of 2025 I had a minor problem with one of the Mitsubishi heat pump system units. The company was quick to troubleshoot the situation. The technicians were courteous, knowledgeable about the system and thorough. It required several visits to diagnose the problem and fix it. The manager, Nick was very responsive to the situation which required bringing out an expert from Mitsubishi. All of this work was covered under my warranty. The problem was fixed and I could not speak highly enough about the company’s policies and customer service. I would highly recommend them for all facets of their work and standing behind their installations. I am very happy to be working with them for my continued maintenance. They are an excellent company. Sincerely, Susan Coursey"
