"I enthusiastically recommend this company. Mehmet was always prompt for appointments and texted to let you know he was on his way. His crew worked from 7 am to 7 pm and got our new central A/C system installed in one day during a heat wave. Very professional outfit, polite and cheerful to have around."

"We had an older Heatmaker combination unit boiler that was 32 years old that needed to be replaced. We started out with several estimates and first decided what could be used in our space constrained garage. We decided on a Navien combination unit and focused a obtained a couple more estimates. Dawson in fact was one of the last estimates we obtained. While Dave from Dawson had the benefit of us being well along the learning curve, he was able to answer all of our questions about the new unit and how best to solve the condensate dilemma. He even was spot on with regards to treating our well water to minimize scale buildup in our new boiler. We knew we had reached that point where we felt we had found the best installer in Dave. Dave verified his condensate solution with the local township inspector and we scheduled the install date in two weeks. Carlos and Pablo showed up on time and dismantled the old unit and piping and did a first rate and well thought out installation job. Carlos had extensive experience installing these Navien units and it really showed. They managed to work in a tight space that PSE&G’s installers would not have with relocating a well tank. After all the plumbing was done, Ricky did the electrical work and adjusted some final dip switch settings before firing up the new boiler. Dave and his crew really are top notch. His front office staff (Wanda and Ondrea) made the PSE&G interest free financing and permitting approval process seemless. We are looking forward to the operation and efficiency of our new high efficiency boiler for years to come. If you are installing a Navien high efficiency combo unit, we highly recommend using Dawson Mechanical!"

"Kevin was great! The rest of the company not so much. Kevin diagnosed the problem immediately as the thermostat, had a replacement in the truck, and completed the installation of the new unit quickly. He showed me how to program the updated version, and everything seemed to be fine - until the next morning. Turned out the replacement was defective. When I called, I was told that they might not be able to get back to me that day, but Kevin interrupted his schedule to come back and put in a new (and working) unit at no charge."

"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."

"The unit I had purchased from Home Depot had a piece missing, this was noticed by Easy Flow and I returned it to store for a new one. Once again, Easy Flow inspected the new unit and recommended I return it as it seemed the unit was previously installed and removed before being returned to the store. I finally picked up the third unit with a Home Depot employee verifying that it was brand new and Easy Flow installed it. I appreciate that Easy Flow remained while I went through the return process.

"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!

"Keith and his crew are extremely professional and knowledgeable, and did an outstanding job installing a heat pump and brand new ductwork into a difficult old house. They notified me of arrival times, were prompt, neat, and did the work efficiently and quickly. I highly recommend this company and will be using them again for future projects!"

"I needed to install a water powered sump pump. Tom gave an estimate and actually charged me less because the digging didn't take him as much effort as he had estimated. He made sure I got the equipment in order and he returned an earlier delivery since he wasnt satisfied with its float assembly. The job was completed professionally and on time. On top of that he is a very nice person to deal with and fixed a couple of minor issues with my other faucets at no extra cost. Well recommended an I will call him again if I need any plumbing work done."

Install Boiler questions, answered by experts

Using heating oil to heat your home has its advantages, but it also has its disadvantages. 

Consider these drawbacks before installing a heating oil system:

  • Heating oil prices fluctuate frequently

  • Risk of oil spills or leaks

  • Produces more air pollution and soot compared to a gas furnace

  • Regular maintenance required for equipment

  • Need to reorder heating oil consistently to avoid running out

Propane is more cost-efficient than natural gas on a per-unit basis because it produces twice as much heat energy as an equivalent amount of natural gas. But propane is not ideal if you already have a gas line installed. The best choice for your home depends on the efficiency of your appliances and the amount of installation required of your fuel choice.

If you go to turn it counterclockwise and it won’t turn anymore, it’s open. Like most other valves, you should be able to turn a radiator valve counterclockwise (to the left) to open it and clockwise (right) to close it. To close a radiator valve, turn it clockwise until you meet some resistance and can’t turn anymore, but do so carefully to avoid breaking the valve.

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.

Professional HVAC installation requires licensed expertise in several areas, including electrical- and plumbing-related work. An HVAC team must know how to safely handle regulated refrigerant chemicals and the gas, oil, or propane used in furnaces and boilers. A proper HVAC installation protects your home from energy loss, fires, and even carbon monoxide leaks.
