"Williams & Associates replaced an ancient, very large old boiler in my very large house. Bruce calculated the necessary size and found a suitable boiler. He and his crew thoroughly cleared the radiators and lines before removing the old boiler and installing the new one. They checked all the radiators and added new valves as needed during a lengthy checkout. It took several days to do all the work. Throughout, Bruce explained what they were doing and why as well as recommending changes/additions to the original proposal. They were even cheerful about removing the original "Mary Jane" from the basement. I would definitely recommend them to anyone using steam heat. Great job!"

"John was outstanding! He meticulously diagnosed the problem and installed the equipment after tracking it down at 2 local supply houses. He kept us informed every step of the way and worked diligently until the work was completed. This is the second time we've asked Mull Bros. to perform a service at our house. We received excellent service both times. Mull Bros. is a highly professional company that has exceeded our expectations.

"HIGHLY recommend! needed a kitchen faucet replaced. sent in request on home advisor at 730am. got a call at 8am to confirm time table and also a rough quote for the work needed. got a call at 830 from Ed that he was coming in 30min. Work was completed perfectly in less time than quoted and price was under initial quotes which i appreciate. I had a quote from aiello at 7am for over $1000 more than this job. I bought my own faucet for this saving some money, but ultimately saved $1000 paid $220 for visit and work completed. ABSOLUTELY recommend Ed and this company for any needs."

"Juan responded quickly on a Sunday afternoon. He was very knowledgeable and fixed the broken part. Fortunately, Juan had the part in his truck and was able to get my furnace working again. The service was impeccable! However, the weekend rates are expensive the service cost me $699 for installation of a $70 part. The 2-hour service call was $500 ($249 per hour)."

"Tim came out when he said he would, was friendly and courteous.  He diagnosed our problem and proposed a solution.  He patiently answered all our questions and installed the new equipment that very day. In a few short hours we had a functioning water system with much better water pressure than we ever had here before.  We knew the complete price ahead of time. I am extremely satisfied and very glad to have found a good, reliable, and trustworthy plumber who is local.

"I had APEX install ductless mini splits in my house. Ive used them previously on other HVAC work, and I love the knowledge and expertise they bring. One of the main reasons why I continue working with them is their professionalism. Before I discovered them I was using a company out of downtown Hartford that used to send drug atticâ s to my house. With Apex you have nothing to worry about. Quality work, good pricing, and professional."

"Had my gas furnace and whole house air conditioning unit replaced. Took two full days. The installers were proficient and knew what they were doing (especially Rich Fee). They took the time to explain the work and the new system features including new digital thermostats. All in all, I was very pleased with the service and the price."

Install Boiler FAQs, answered by experts

Installation costs range from $4,000 to $12,000, depending on unit size, efficiency rating, and labor.

When winter rolls around, and you turn the heat on for the first time in a year, it’s normal to sense a light odor. This could smell a little like burning because some dust has gathered in the heating unit over the warm months and will fade away shortly after. However, there are some smells you should watch out for and take caution around: an egg-like sulfur smell or an electrical burn odor would indicate there’s something wrong. Turn it off and call a professional for maintenance as soon as possible. 

To figure out if your boiler is worth repairing or if you need to replace your boiler, first figure out how old the unit is. Boilers last 15 to 20 years, so if your unit is 15 years old or older, it may be better to replace the entire thing depending on the severity of the problems. If it’s not quite that old, then it’s probably worth repairing. Another thing to consider is whether your warranty covers any of the repair costs. If so, it may be worthwhile to repair your boiler to keep it running.

If you want to have hot water in your home and part of your plumbing system, you'll need a hot water heater. An alternative may be to heat water as you use it, such as by boiling what you need on the stove. But that's much less efficient and takes considerably longer than hooking up a water heater. Another option is to rely on appliances, such as a dishwasher or washing machine, that heat the water themselves.

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).
