“This excellent company has been a problem solver and repair and maintenance WIZ for our home and a big house (I am a caretaker for) at least 7 years. They are the best. I highly recommend them.“

“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“

“I recently had an urgent plumbing issue, and Tim from TJP Plumbing was the only plumber in the area to respond to my emergency service request. He arrived first thing the next morning and quickly diagnosed the problem. While we initially thought it was a leaky pipe in the wall, Tim discovered it was actually a clogged waste line. His thorough investigation also revealed that our cesspools were full and needed pumping. Thanks to Tim's prompt and professional service, the issue was resolved efficiently. Highly recommend TJP Plumbing for any plumbing needs!“
