"I called Mehmet based on the Angie's list recommendation and the terrific reviews. Mehmet worked around my work schedule and came after 5. He identified the problem and installed a new capasitor. He was in and out of here in 30 mins. A week earlier a rip/off big company (Varsity) claimed the unit could not be fixed for under $3500 and recommended I install a whole new system for $11,000. Mehmet's skill, reasonable price and honesty were well appreciated here."

"Rob and his team arrived in time. They were very professional, personable and cleaned the place in detail. They made it spotless. Contractors had left the bathroom in a bad condition and Rob's team made it clean and shiny like a hotel's bathroom. The windows were left from contractors full of dry cement which no one could remove before. I did not expect them to be able to remove the cement but thought I should ask. They were able to make them like new again and saved me from buying new windows!"

"I called in the late morning and the friendly office person took down all my information and gave me a window of time between 2-4 PM. She later called and said that the serviceman got done early with his morning job and would like to know if he can come earlier. The repairman, Andrew, was professional and knowledgeable. He opened the heating system access doors and found an error code. He promptly fixed the issue and also cleaned another part, which he said could give problems in the future. He took the time to explain why the problem occurred and what he did to fix it. He also took down the make/model of the heating system in case it needs more work in the future. Since there were not parts required, I was only charged the minimum service fee. The heat is working solidly now."

"Ken did an outstanding job installing our new furnace and chimney liner. Ken had previously done several smaller plumbing jobs for us, giving us great confidence that he?d do a great job installing our new furnace and liner. He didn?t disappoint us. You can tell that Ken takes great pride in his work, and we felt that at every turn, he went above and beyond for us. He carefully thought out what needed to be done, and he patiently explained his plan to us. Ken worked well into the evening to get our heat on as soon as possible. He kept us up-to-date on the progress, and when the installation was complete, he took the time to explain how the new system works. Ken is a pro. He is personable, knowledgeable, hardworking, even-tempered, responsive, and dependable. We will continue working with Ken, and without any reservation we highly recommend him.

"Anthony and his crew were awesome! Always available, punctual and professional. Nice clean work and fast. They're pricing was better than most and am very happy with the service. They installed a ductless ac unit with 2 heads in my basement. From start to finish they were great. I would recommend them to anyone."

"The installation of my Hvac system could not have gone any better. Joe was on top of everything from contacting me when he couldnt make the original installation date, to following up and waiting on me to have the electrical upgrade, was on time and punctual both days its took to do the work and made sure he explained everything and I had a clear understanding of everything. I would definately recommend and hire again for any Hvac needs"

Install Boiler FAQs, answered by experts

Boilers provide even heating, energy efficiency, and a quiet operation compared to forced air systems.

Steam boilers require flushing at least every six to 12 months to keep them operating effectively for as long as possible. Depending on your water quality and frequency of use, you might need to do this more frequently. The flushing process helps to remove problematic buildup of sediments. While a boiler contractor near you can perform a thorough annual flush, learning how to drain the system yourself means you can do this monthly if you experience speedy mineral accumulation because of hard water. 

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.

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.

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.
