"Fontana Brothers installed my new Bosch HVAC system, and I couldn’t be happier with the experience. Freddie and Shaquille arrived exactly on time, worked efficiently, and left the work area cleaner than it was before they began. Their attention to detail and professionalism were outstanding. As a Realtor for more than 30 years, I’ve dealt with many HVAC companies, and Fontana Brothers continues to be one of the very best. They consistently deliver excellent service to both me and my clients, and their pricing remains highly competitive. I trust them completely with my referrals. Special thanks to Dan Fontana, who heads the service department — always organized, responsive, and helpful — as well as the entire office staff, who are consistently friendly and a pleasure to work with. I will absolutely continue to recommend Fontana Brothers to others seeking HVAC installation, repair, or replacement."

"Excellent. They installed the system 3 months ago. Today the system shut down due to a fluid back up when I was cleaning the drain line. The technician came out within 2 hours and promptly got the system up and running and checked the drain line. He also installed a new end to the drain line outside the house."

"Tim and dan know water and how to treat the issue at hand. Used them about 8 years ago at my previous house (which has had no issues since installation). So had them come out to assess and correct my water issues at my new house. They were very fair, friendly and prompt. I would highly recommend them!"

"Plumber was prompt and arrived when scheduled.  He unclogged my bathroom pool toilet.  He then gave me a price for the installation of a laundry tub.  He came the next day and neatly broke through the garage wall to get to the pipes to be able to install  the laundry tub.  This precise cutting of the sheetrock made it possible for my husband to reinstall it  without any problem.  I would recommend this company and will use them again."

Install Boiler FAQs, answered by experts

To figure out if your boiler is worth repairing or if you need to replace your boiler, first figure out how old the unit is. Boilers last 15 to 20 years, so if your unit is 15 years old or older, it may be better to replace the entire thing depending on the severity of the problems. If it’s not quite that old, then it’s probably worth repairing. Another thing to consider is whether your warranty covers any of the repair costs. If so, it may be worthwhile to repair your boiler to keep it running.

DIY is not recommended due to safety risks and technical expertise required. Hire licensed professionals.

You can use a boiler and a furnace, although it’s not common to use both for whole-house heating. For example, your furnace may take care of HVAC heating through your vents, while a boiler powers your floor-based radiant heating in the bathrooms. Mixing and matching like this gives homeowners a variety of heating possibilities.

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.

The cost of propane and related services varies depending on tank size and location but generally ranges from $500 to $2,500 for installation and initial fill.
