"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."

"I had a great experience with this company installing my new boiler. Their pricing was fair compared to other estimates I received. Dave walked me through the entire process and answered all my questions, and his team came in and did a great job with the installation. With so many scammers out there, I truly felt comfortable working with this company and will absolutely use them again in the future."

"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."

"Mo was a very able, responsive and professional technician who installed our furnace in one day and our new boiler two days later. He patiently answered my many questions, walked me through why we needed two new units (instead of repairing our old ones) and worked well and efficiently. It was painful to have to pay that much money at once for a furnace and a boiler, but Mo made it as positive an experience as it could have been. I am grateful to him and his assistant for their work and professionalism."

"se  Rob is a dream come true. As a single woman running my own home and being very particular.....it is extremely important to be able to discuss the job, hear all the details, and employ someone who is honest, honorable, well qualified, neat, and highly informed. I first hired Rob for the drain problem. He accomplished that efficiently and neatly at a reasonable price. We discussed options for a back up for the sump pump. Having a finished basement, I am always concerned about water. I have never lost electricity during a rain storm....but the possibility always takes up space in my brain. I have a portable generator....but I have to be home to start it. Today Rob arrived on time and installed the back up for me. It took the whole morning as he predicted. He explained how it all worked and it is a beautiful thing. I so appreciate knowledgable and personable service. I highly recommend Easy Flow Drain and Mechanical LLC for any plumbing needs. Oh....one more thing...he noticed a leak in my fairly new furnace exhaust piping. He pointed it out and gave me several possible reasons for the leak so I could intelligently discuss it with the company that installed the new energy efficient furnace. What else could you want from a plumber? I was extremely satisfied and impressed with his service. I'm also grateful for Angie's List!!!!

"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!"

Install Boiler questions, answered by experts

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.

The best time of year to purchase or replace an HVAC system, including components like an air conditioner or furnace, is during the off-season—spring and fall. During these periods, HVAC professionals are less busy than in summer and winter, when extreme temperatures create urgent demand. Shopping during the off-season can lead to savings of 10% to 15% on an AC unit and allows you more time to find the best deal and other cost-saving incentives. Typically, air conditioning units go on sale in the fall after demand drops, while furnace prices tend to decrease in the spring.

Installing a boiler requires training, a specific skill set, and extensive experience. Boiler installation can be extremely dangerous, as it involves working with water lines, gas lines, and electricity. For this reason, it’s strongly recommended that you hire a professional to install your boiler. Some states even consider it illegal to work on a boiler without the proper licensing.

The radiators closest in proximity to the boiler heating system will heat up first. Radiators in rooms farther away from the boiler will take longer to heat up and may be the coolest rooms in the house. The radiator unit itself should heat up evenly; otherwise, there may be trapped air inside it.

It takes about five to 10 minutes for heat to reach a radiator, then about one hour until the radiator fully heats up a room. The exact duration depends on the size of the room and how far away the radiator is from the boiler heating system. Heating up an entire house could take up to two hours.
