Why? Quite simply, because we strive for perfection. If you are hoping we will use cheaper materials, hurry through an installation, or overlook restrictions, P.J. Fitzpatrick, LLC, is not the company for you. We believe that when it comes to your home, the job should be done perfectly and last a lifetime. This might not make us the cheapest company in the area, but we stand behind our work and leave our customers extremely satisfied. So much that they refer friends, family and neighbors without hesitation. If something goes wrong with our installation, it's not your fault, it's ours. Our responsibility doesn't end once we pack up our tools and leave. If something breaks, malfunctions, or just plain doesn't make you happy, we'll fix it - for as long as you live in your home.

"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 Repair questions, answered by experts

It’s not customary to tip HVAC technicians, and most professionals won’t expect it. However, it’s a nice way of showing your appreciation for the work they do, especially if they come out in inclement weather or on a weekend or holiday to fix an emergency issue if your heat or AC goes out in extreme temperatures. A good tip would be between 10% to 20% of the total bill, depending on how above and beyond the tech goes for your repair and on the total cost of your HVAC repair or service. For something like a routine tune-up or scheduled maintenance, tips aren’t expected.

HVAC quotes may be negotiable. It’s important to be upfront about what you need, your budget, and your expectations. However, your contractor must suggest repairs or the system they think is best for you, and those things may not be negotiable. So, when can you negotiate an HVAC quote? When installing a new system, you may not need to replace ductwork or install specialty items such as whole-home air purifiers. If your contractor is bidding on those items or others you don’t need or want, ask them for a quote on only the equipment and services you need.

If your boiler is 20 years old, it’s time to get a new one. Although it may seem to be working fine, it’s likely eating up more fuel than it should. Also, compared to a brand-new boiler, one that’s 20 years old is probably not working as well. When you get your new unit, you’ll notice that your home is heating more quickly, and the heat is consistent throughout all the rooms.

A heating expert will be able to clarify whether it's worth the cost of replacing your radiator based on the cost of repairs. Between parts and labor, you'll pay between $250 and $2,500 for a new radiator depending on the type of unit. If the long-term costs of fixing a radiator are higher than replacement, it's best to update your model.

If you hire a professional to replace your gas furnace’s thermocouple, you’ll usually pay between $150 and $250. Since thermocouples often fail due to a lack of maintenance, you may be able to avoid—or at least delay—a thermocouple replacement by taking good care of your furnace. This means scheduling annual furnace inspections, changing the filters at least once per season, and cleaning the burners occasionally.
