"During the installation my wife had to run errand, plus make a slight diversion to the hardware store. Mo was nice enough to talk on the phone to the person in the store and explain in detail what part my wife needed for the installation. I would highly recommend the quality of his work, professionalism and patience."

"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!

"We needed a new high-efficiency boiler to replace our old one that broke down after seventeen years (of inefficiency). Ed was great to deal with from start to finish. We shopped around, but Ed was the most communicative (with text and calls) and offered the fairest price. Will definitely use Orange County Mechanical again!"

"The owner, Frank, was excellent and professional. Also his guys were very efficient by doing the job. They installed a brand new furnace and the job was immaculately done. they came to do the job when promised and finished in a timely fashion. The owner, himself, stayed at the job site after installation to make sure the equipment function good. they also call back after certain time to make sure that everything was good with the system. This is a company that do the job and do not disappear. They care about their customers. I recommend them and will keep using them."

"In each and every instance, the plumbing technicians that have done the work have always been very professional in their approach. Meeting them at the door and the technician is putting on booties so as not to scratch or damage the floors, was the first sign that the company cared about its customers. After an assessment of the work requested was completed and a price was determined, the work proceeded. It was also just the beginning as in each and every case the technician demonstrated expert technical skill, in a deliberate and cautious manner. Drop cloths were placed down; tools and equipment were carefully located so they would be accessible yet out of harm’s way. The work was completed with great attention to detail. I especially noticed this when the double vanity work was being done. The technician, Mike, noticed immediately that both waste lines were, somehow back pitched. He advised me and agreed to go deeper into the project to correct the issue. Once completed, measuring for the new cabinets was critical for where the waste lines and supply lines had to go through the cabinets. He measured and re-measured to make sure they were correct and they absolutely were. The cabinets fit perfectly! The professionalism continued when it came time for the toilet installation. A new flange had to be installed because the old one was rusted out. Not problem. Then he got out the plaster and buckets to install the toilet. I asked why the plaster and he stated that it was company policy to mount the toilet in plaster to avoid any floor water from getting to the flange and to also stabilize the toilet. This was way and above what I expected. When he finished, the toilet was perfectly installed and with the plaster around the base, it looked nicely finished and was steady as a rock. The clean up for all the jobs was excellent. As you can infer from this review, I would highly recommend O’Brien Plumbing and Heating to anyone. The price is fair and competitive with other full service companies and knowing and seeing how professional and caring the technicians are, is a direct reflection on the owner and how he runs his company. I would never hesitate to hire them again and again."

Install Boiler FAQs, answered by experts

On average, you’ll need about two gallons of oil per day to heat your house when it’s 50 degrees Fahrenheit outside. Most oil tank capacity is about 275 gallons, and heating your house with two gallons of oil per day will last about four and a half months. This consumption will vary depending on the climate and average temperature in your location. For example, if the winters are longer and colder where you live, you’ll probably need to refill your oil tank at least once to get through the winter.

It can take anywhere from four hours to three days to replace a boiler with a new one. How long your particular boiler installation takes will depend on whether you need a gas line installed and if you’re switching to a new boiler system. 

Replacing a combination boiler or standard boiler with the same system should only take four to six hours. Meanwhile, switching from a conventional boiler system to a combination boiler system could take a few days.

An expansion tank must always be installed on the supply side, which is the side where the boiler sends water out to heat the systems. That placement allows the water to push against the air and condense properly as it is heated, then circulated through the system. Professional installers can recommend the best place on the supply side for an expansion tank.

If you hear your radiator clanking even when it’s turned off, it’s typically because there’s trapped water or air in the system, causing a pressure buildup. When you hear significant clanking, popping, crackling, or banging in a radiator that’s turned off, you’ll want to bleed the pipes or call in an HVAC specialist to deal with the problem (and prevent it from happening in the future).

The best way to compare HVAC quotes is getting a few detailed quotes from local companies with good reputations. Then, go over the quotes line by line. Protect yourself by insisting on in-person estimates that include equipment manufacturer names, model numbers, SEER ratings, amounts and numbers of materials, details of warranties on equipment and labor, and other specifics. 

Knowing the exact equipment and materials is the only way that you can fairly compare quotes. Quotes that are much lower than others can be a sign that the company isn’t providing the best quality service or materials.
