"We had our old boiler removed and a new 250,000 BTU Weil-McLain installed. The experience was great. The price was really fair, especially for the quality of work. They showed up right on time, got straight to work, and you could tell they knew exactly what they were doing. Everything was done in a very organized and professional way, but still felt easy and stress-free on our end. What I appreciated most was how clean and quick they were—no mess left behind, and the job was done faster than expected without rushing anything. Overall, just solid, reliable service. Would definitely recommend them to anyone needing boiler work."

"Great experience from the first time I made a request on HomeAdvisor. Leo called me within 5 minutes to inquire about my service. He came within 2 hours that same day to give me a free estimate and determine what work including all the permits needed to be done. I picked a relatively short turn around time to complete the work which included upgrading from 100 amps to 200 amps and taking out and installing new box and outside circuitry. Leo gave me a written estimate, itemized and emailed it to me and work was done within a week. When his team arrived they were on time with all of the necessary supplies and started working. One of the most details I saw in his work was that he was there at the work site the entire time making sure his crew was doing everything right and completing the work on time. It was about 7-8 hour job and Leo was there the entire time. I was impressed with what I saw I decided to ask for another task which included another light fixture in front of the garage because I knew he would do a good job. Leo and his workers are good, honest and dependable."

"Alfonso, Dave and Al were outstanding!!! Professional, courteous and simply nice individuals! I meet with Alfonso last Tuesday to discuss my boiler problems and what needed to be done. I can honestly state after talking with him I knew I had chosen the right company even if, it cost more than I had anticipated. I trusted him and did not feel pushed into something. On the day of installation any questions I had were answered, they cleaned up everything and I am 100% satisfied with everything! (The Unit installed, timeliness, workmanship, cleanup and the individuals themselves!) I would highly recommend this company without any reservations, and yes their manager Mr. Gil Karni was a man of his word, from whom he sent to do the job and taking into account my personal needs with the time of day I had available for all."

Install Boiler questions, answered by experts

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.

Unless they are connected to the same system, boilers and water heaters will both need their own expansion tanks. The only case they wouldn’t have separate expansion tanks is if the boiler is pulling double duty and managing a heating system while also supplying hot water for a home. In which case, you may not need a hot water heater.

Most experts recommend getting three to five HVAC quotes from licensed, insured, reputable local heating and cooling companies. Getting multiple detailed HVAC quotes (but not too many) lets you compare the equipment, services, and prices of several contractors without being overwhelmed by options. It can also let you see if one contractor’s prices are much higher or lower than the others and give you a chance to ask for clarification. That way, you can weed out any contractors who aren’t providing quality services or materials and find the company that best meets your budget, quality requirements, and long-term goals.

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.

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.
