"The technicians performed routine maintenance and repair of two boilers their company installed two years ago. They did a thorough job of flushing the water heating lines, testing the system, and re-installing a low-water shut off valve that had failed last year. I have used this plumbing company for years and will continue to do so, highly recommended to people in the Northeast New Jersey area."

"I don't have enough good things to say about Rob. He was friendly and knowledgeable from first contact. He was able to come out the same day and give an accurate quote. He kept in contact until the day of the install. He arrived on time on the day of the install and finished promptly. He had to climb over the washer and dryer AFTER it was stacked in the closet to complete the install. Rob brought all the tools and pieces necessary and left no mess. Rob was a pleasure to deal with and I would recommend him without reservation. His prices were fair for the amount of work he did and I will definitely use him in the future should we need."

"My air conditioner condensers were struck by a power surge this summer. They were beyond repair, after repair inspections by 3 different firms, including Braido. Since my house is 21 years old, I knew that eventually the furnaces would have to be replaced as well, so I bit the bullet and replaced both the air conditioners and the furnaces for the upstairs and downstairs zones of my home. 
I came across Braido's name from a local community board on Facebook. I checked their ratings out on Angie's List and decided to have them inspect and then provide an estimate.
They were knowledgeable, helpful and reasonable throughout my decision making process. When we finally did decide to go with Braido, we were glad we did. They offered 0% financing on the balance and charged, what I believed. to be a reasonable rate, since I could compare their price to 3 other estimates. 
For the install, they actually came 1 day early to lay the slab for the condensers outside because rain was being forecast. Smart thinking!
Then, what was supposed to be a 3 day install, took only 2. They were timely, professional and tidy. Would definitely recommend!

"Todd called immediately after your service magic appeared and made contact with me via phone. Pleasant discussion with his service type and what he does. Made an appointment to perform service on my hot water heat oil boiler. Did all work professionally and very clean. Discussed various aspects of what is out there for efficiency and rated the condition of my boiler. Had a problem with the boiler a week later and he came out to look at it. did additional cleaning and checking out the system. Diagnosed the possible problem and gave me fair options for possible repair if needed. Todd is fair, reasonable and very good service."

Install Boiler FAQs, answered by experts

The cost to install a steam boiler varies depending on the type, fuel used, and your house size. The average cost to install a boiler is $5,900. You could spend $2,000 for a basic electrical steam boiler or up to $9,000 for a high-efficiency oil-burning steam boiler. Boiler installation is a job that’s best left for professionals to complete, and, in some states, only licensed installers can legally complete the job.

Always consult your manual for specific pressure numbers. Many expansion tanks come pre-pressurized at a specific PSI range, anywhere from 12 to 40 PSI, designed for a range of home boilers. You should not have to pressurize an expansion tank yourself, only the boiler system. If your system has a tank that needs to be manually pressurized, this is generally a job for professionals and their tools.

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.

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.

No, there isn’t always water in radiators. In a one-pipe system, water is constantly circulating from the boiler to the radiators and back. In a two-pipe system, water travels through two separate channels: one that goes to your radiators and one that returns back to the boiler so it can heat up again.
