"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."

"He is honest. There's something to be said for honesty. It's a family run business, but he does everything the right way. Some of the other providers give poor customer service or rip people off and can't get business in their local area and are moving into our area. Lennox is good stuff. He went all the way to Philadelphia just to get me a part."

Install Boiler questions, answered by experts

Most home boilers will need an expansion tank. That’s because these boilers are closed-loop systems, where the water is trapped. An expansion tank is needed when the boiler heats the water and it expands, allowing air to condense in the tank to make room for the water. Other types of boilers don’t use an expansion tank, such as traditional steam boilers, but these aren’t as common. And hot water tanks may be able to use a pressure release valve instead. When in doubt, call in a pro to take a look.

The radiators closest in proximity to the boiler heating system will heat up first. Radiators in rooms farther away from the boiler will take longer to heat up and may be the coolest rooms in the house. The radiator unit itself should heat up evenly; otherwise, there may be trapped air inside it.

Using heating oil to heat your home has its advantages, but it also has its disadvantages. 

Consider these drawbacks before installing a heating oil system:

  • Heating oil prices fluctuate frequently

  • Risk of oil spills or leaks

  • Produces more air pollution and soot compared to a gas furnace

  • Regular maintenance required for equipment

  • Need to reorder heating oil consistently to avoid running out

You can replace baseboard heaters with many other types of HVAC systems, including forced-air furnaces, hydronic heating, and heat pumps. Each one has its advantages and disadvantages, so the best choice for you will depend on your budget, preferences, and the design of your house. If you aren’t sure which option is right for you, ask an HVAC pro for guidance.

Overall, heating your home with an oil furnace tends to be less expensive than heating your home with an electric heating system. Oil heating systems stay warm for longer periods of time without drawing a constant electrical current to maintain a temperature. Plus, heating oil systems typically have a longer lifespan and lower price tag than their electrical counterparts, resulting in short- and long-term savings.
