"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."

"Very well. Difficult job. Entire system had shut down. Multiple reasons. David was fabulous in figuring out the various issues, which parts were warenteed, recalled etc. Time consuming, and a few set backs, but David will get the job done!"

Install Boiler questions, answered by experts

On average, you’ll need about two gallons of oil per day to heat your house when it’s 50 degrees Fahrenheit outside. Most oil tank capacity is about 275 gallons, and heating your house with two gallons of oil per day will last about four and a half months. This consumption will vary depending on the climate and average temperature in your location. For example, if the winters are longer and colder where you live, you’ll probably need to refill your oil tank at least once to get through the winter.

Costs depend on issue severity, parts needed, and labor rates.

Always consult your manual for specific pressure numbers. Many expansion tanks come pre-pressurized at a specific PSI range, anywhere from 12 to 40 PSI, designed for a range of home boilers. You should not have to pressurize an expansion tank yourself, only the boiler system. If your system has a tank that needs to be manually pressurized, this is generally a job for professionals and their tools.

You can save money on heating oil through a combination of improving home efficiency and smart purchasing strategies.

Home Efficiency and Usage:

  • Improve Insulation: Ensure your home, especially the basement and attic, is well-insulated and sealed against drafts to prevent heat leakage.

  • Manage Your Thermostat: Use a properly calibrated and programmable thermostat. Lower the temperature by a few degrees, particularly when you are away from home or asleep.

Purchasing Strategies:

  • Buy in the Off-Season: Order heating oil during the summer months when prices are generally at their lowest. This strategy is most effective if you have a large primary tank or a separate storage tank to accommodate bulk deliveries.

  • Consider a Delivery Contract: Some companies offer contracts with a set price for the term. This can lead to savings if market prices for oil increase, but you might pay more if prices drop.

Yes. Boilers need water to run without overheating, also known as dry firing. If you run it without a sufficient volume of water, either because of a burst pipe or a leak, you run the risk of damaging your machine or jeopardizing the safety of your home as a whole. When in doubt, shut off your boiler and repair any plumbing issues before turning it back on. Alternatively, consider installing a low-water cutoff (LWCO) before any issues arise. This gadget will protect your boiler by monitoring water levels and automatically shutting it off if it gets too low.
