"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

The best time to buy home heating oil is in the summer when the demand is lowest, as the prices are usually lower. However, waiting until the summer to buy is often unavoidable unless you install a separate storage tank. If you have the space for a second tank, you can expect to pay between $1,000 and $4,000 for the oil tank replacement or installation, depending on the capacity and location. You could quickly recuperate these costs, though, by stocking up on heating oil in the summer and avoiding deliveries in the winter when prices are highest.

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.

You should get anywhere from three to five quotes for HVAC replacement to get an idea of the average cost of a new unit. Although this quote-collecting process can be time consuming, it allows you to compare what work is required, what type of unit you should install, and how much you should expect to pay for the service.

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.

Many HVAC companies offer free quotes and free estimates for repairs and new HVAC systems. Others offer low-cost quotes or apply the cost of the estimates or diagnostics to your final bill if you hire them. Be aware that some companies advertise free HVAC quotes and recoup the costs by charging more for their services. Free HVAC quotes are never truly free—they cost the company time and effort—so be a good customer. Also understand that you may end up paying for free quotes in another way if you don’t hire a reputable company.
