"While having my siding removed and replaced, decided to insulate the exterior walls. They coordinated with the painter and checked the weather for when the project could be done. Also, the estimate was given several months in advance and was still honored once the project got going. They needed to come out twice to install the insulation because the siding took time to come off the house, but they were more than willing to work with the painter's schedule to make sure things got done in a timely fashion. Friendly folks who take time to answer questions and did excellent work getting the house insulated and now operating efficiently."

"He came in and looked at the air conditioner and the furnace and pulled out the book and calculator. He suggested me all I wanted and he gave me the best quote for it. I am happy with them. They were prompt and the guy was on time for his call. He got down to work and didn’t mess around. He didn’t try to oversell me."

"Prior to calling Bob, we had several guys come in to give us estimates. Bob's estimate was by far the best and the work he did was top quality. He and his guys moved my existing furnace to a new location int he basement and installed a new AC. They also moved the hot water heater. I am very pleased with his service. They were prefessional and respectful. Bob is a straight shooter. Absolutely no BS! I will be using him for ALL of my future HVAC needs. I HIGHLY recommend you call him and have him come give you an estimate if you need service, repair or replacement.

Install Boiler FAQs, answered by experts

Heat pumps are significantly more efficient than boilers, typically providing three to four times the amount of heat for the electricity they consume. While boilers run on fossil fuels, heat pumps use only electricity. This efficiency can lead to long-term savings on operating and maintenance costs. However, heat pumps have a higher upfront installation price compared to boilers. Despite their lower efficiency, boilers remain a popular choice for many homeowners, with 8 million in the United States alone, due to their lower initial cost and less intensive installation process. Ultimately, the best choice depends on your home's infrastructure, your budget, and your personal heating priorities.

Most home boilers will need an expansion tank. That’s because these boilers are closed-loop systems, where the water is trapped. An expansion tank is needed when the boiler heats the water and it expands, allowing air to condense in the tank to make room for the water. Other types of boilers don’t use an expansion tank, such as traditional steam boilers, but these aren’t as common. And hot water tanks may be able to use a pressure release valve instead. When in doubt, call in a pro to take a look.

Boiler installations and replacements cost between $3,600 to $8,400. Expect to pay around $5,900 on average for a new boiler, including installation. Adding new radiators or heaters to the boiler may include separate costs if you are also upgrading those components, so the final price may be higher. To decrease costs, you can look for local energy rebates for using a boiler and wait until installers are offering discounts for a first-time installation.

A furnace is a big unit where gas, heating oil, or electricity heats the air. The warmed air is then pushed back out through ducts and vents. 

A boiler uses electricity, heating oil, or gas to heat water that is pushed into the room through a radiator. This is one of the oldest and most effective ways to heat a house, but radiators can also be unsightly and leave hot and cold spots in the room.

Heat pumps use a refrigerant to move heat from outside into the house and return it to the room through ducts and vents.

Most experts recommend getting three to five HVAC quotes from licensed, insured, reputable local heating and cooling companies. Getting multiple detailed HVAC quotes (but not too many) lets you compare the equipment, services, and prices of several contractors without being overwhelmed by options. It can also let you see if one contractor’s prices are much higher or lower than the others and give you a chance to ask for clarification. That way, you can weed out any contractors who aren’t providing quality services or materials and find the company that best meets your budget, quality requirements, and long-term goals.
