Family owned and operated since 1969, Grant Heating & Cooling is a knowledgeable and dependable resource for meeting all your comfort needs. Contact us for installation, maintenance or service
"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"

Boiler repairs FAQs
The average cost to install a new water heater is around $1,300, but you can expect to pay between $875 and $1,750, depending on the kind of water heater, the size of the unit, and the professional chosen to complete the work. Tankless water heaters can push your price higher, as installation is more complicated, with prices as high as $3,500. The location and accessibility of your water heater will play a role in the project cost, as those sitting in tight spaces like a crawl space will drive up your labor costs.

It is very difficult and dangerous to install your own water heater, so we strongly recommend against tackling this as a DIY project. Not only will you need to wire your water heater, but you’ll also need to connect plumbing to the intake and outlet. Sweating copper pipes and connecting wiring properly are skills most DIYers don’t have, and even if you do feel confident you can do it, working with water and electricity always leaves the potential for electrocution. Hiring a local water heater installer is well worth the investment.
The average cost to hire a plumber is around $100 an hour but can vary between $45 and $200 an hour depending on the plumber’s experience and the repair that you need. It’s also important to note that these prices can go up on holidays, and emergency plumber rates average $150 per hour, in addition to a flat-rate trip fee of $100 to $350.
