"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."

"Since I moved into my apartment around 20 years ago, I've had problems with the bathroom exhaust fan. When I turned it on, often the circuit breaker would be thrown. Finally it got to the point where it just wouldn't work at all - if I tried to use it, the fuse was blown. I posted the project here and Leonel of Berardi contacted me shortly afterwards. After looking at it he determined that the fan was the wrong kind and wasn't even installed properly. He explained it to me, ordered the correct fan, and had someone come over to install it. Now the fan works perfectly, no more blown fuse, and it's less noisy, too. They could have played this differently, slapped on a bandaid on it and had me call again and again for the same problem, but Berardi did the right thing. I'd recommend them to anybody who needs electrical work done."

"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

In some cases, conversion kits are available, but not all boilers are compatible. Conversion may require significant modifications and should only be performed by a qualified professional. Before making a decision, compare conversion costs to the cost of a complete replacement to determine the most cost-effective and reliable option for your home.

One of the easiest ways to determine which type of furnace will work best for your home is to contact a professional in your area. Many HVAC companies offer free consultations to help potential customers determine if they need a new system and which type would work best for their home and the community’s climate.

The cost-efficiency of baseboard heaters depends on the type and how you use them. Generally, standard electric baseboard heaters can be expensive to run because they use electric resistance heating, which is less energy-efficient than systems like forced-air or heat pumps. However, hydronic and gas versions are typically much cheaper to operate. Hydronic models are more energy-efficient because they heat a liquid that retains warmth longer, preventing the thermostat from turning on and off as often. The overall running cost is also influenced by local electricity rates, your home's insulation, and your usage habits. To increase efficiency, you can use baseboard heaters for zoning, meaning you only heat the specific rooms you are using.

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

Common problems include leaks, low pressure, and inefficient heating. Regular maintenance prevents many issues.
