"Brandon came out on a Sunday and looked over the job site for details needed to present an estimate. Within a day I had the estimate with 3 options from low to high, all of which were reasonable the only difference being what equipment I wanted to install. Option #1 and #2 were lower end brands that were less expensive but since the difference in price betwee Option #1 and Option #3 was about $1400, I went to Option #3 which was their top tier brand, Carrier that clearly is an industry leader and trusted brand for longevity. I was installing a SINGLE ductless to cool a standard bedroom size room with a 18,000 BTU unit. The job took a total of about 5 hours since they were mounting the unit in a second floor bedroom and they needed to run the power/refrigerant lines two stories down to the compressor mounted on the wall. Everyone from Office Staff Jim to installers were absolutely wonderful to deal with. You can trust this company."

"Setting up the appointment was easy. They offered to come out the next day but I needed to wait until Friday, my day off. Mike showed up on time. Did a good professional job removing and installing a new 50 gallon water heater. Mike also tested my water pressure and noted it was too high. For an agreed upon small additional charge he replaced my pressure regulator and a shut off valve."

Thermostat screen went blank-furnace and A/C wouldn't come on

Chris arrived within 1 hour of my call and checked the furnace first. He found a blown fuse and no power to low voltage wires inside the unit. He then checked the thermostat and found it was no longer working. Chris replaced the fuses and the thermostat with a similar unit and tested the entire system. He then checked my A/C unit for Freon levels and found and repaired a wire that had come loose.

Chris was very pleasant to work with and explained what he was checking and why as he went along. He explained how the new thermostat worked and provided me with both the installation and operating manuals. Great service!

"The access panel on the unit was slightly bent as was the unit. Instead of repairing the installers taped it up with duct tape. The panel fell off and I had to call for another service man to come out and correct the problem. The second technician did a much better job."

"Evening of Valentine's Day we learned our water heater had broken.
Called Bob & Marc the next morning and had an appointment of 3 pm. They were available earlier, but I could not get out of work any earlier.
Spencer was on time and got right to work. He was very professional, careful and friendly.
He assessed that the water heater was broken, drained and removed the old one and installed the new one.
He made sure that the TPM piping was exact, fit and would last. He was very helpful in explaining what he was doing and was even very helpful in providing advice on how to extend the life of this new water heater.
He cleaned up and all that was left was a professionally installed water heater that has been working great.
Thanks for the quick, friendly service (also be sure to use the 10% off coupon found on their  Angie's list page).

"Our wonderful remodeling job was done by Best builders group & their awesome team. After shopping around for more than few months for a good home improvement company, we got to Best builders group. The project manager was easygoing, skilled, honest and perfectionist!! For sure there was no pressure of any kind which caused us to feel very comfortable with him. We decided to remodel our kitchen & the backyard. The work included the installation of artificial turf, plants/flowers while the kitchen was completely updated. They installed new cabinets (upper and lower), countertops, backsplash tiles, lights, paint and more... the new kitchen absolutely looks gorgeous and the house is like a new one. All of our friends and family always amazed when they come to visit. They took extra care of everything and the crew and staff was very nice and polite all the time. We definitely recommend Best builders group to everyone!"

Install Boiler FAQs, answered by experts

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.

If you’re looking for a way to heat your home that is lower in cost and higher in efficiency, you should run the numbers to see what it would look like to switch to gas or electric heat. The best choice for how to heat your home depends on your location, budget, and energy priorities.

If you have a closed-system boiler that requires an expansion tank, you cannot safely operate it without one, as this risks extensive damage or even explosions. You must find a way to make room for the installation. Options include repositioning the boiler, rerouting the boiler piping to a more open area, or performing minor remodeling to create the necessary space. If you are unsure whether your boiler needs an expansion tank or how to best accommodate one, it's recommended to have a local heating service professional assess the situation. They can confirm the requirement and suggest the most practical solution.

Yes, most municipalities require a permit for propane boiler installation to ensure safety and code compliance. Permit fees vary by location and are often included in your installer’s quote, as they’ll handle the permitting process. Ensure that you always check local regulations before starting your project to avoid fines or delays.

In some cases, conversion kits are available, but not all boilers are compatible. Conversion may require significant modifications and should only be performed by a qualified professional. Before making a decision, compare conversion costs to the cost of a complete replacement to determine the most cost-effective and reliable option for your home.
