"Originally had them out for routine maintenance, unfortunately our boiler was misfiring and they tried everything to for it but ended up needing a replacement. Went above and beyond to explain each reason why the 70 year old boiler needed replacement and showed me the deficiencies and wear. Best price and were extremely professional and prompt. Could not recommend them more"

"I have had air systems mechanical install my high efficiency furnace few years ago and recently install my central air. Their prices are lower than the rest. They are always courteous and professional from salesman to office staff. I have nothing negative to say. Always on time for routine furnace tune up appointments. A great company to deal with."

"When I made the first call, the receptionist was friendly and helpful. A repair man was here within 2 hours (amazing!). He was professional, knowledgeable, forthcoming with information and the possible options, and he was very efficient. He was careful to leave no mess: nothing left behind, no foot prints on the floors or rugs. We had Sullivan come back a week later to replace the boiler, and again the experience was excellent. We've met several service people and they have all been friendly, respectful, thorough and very helpful. I give them the highest recommendation possible."

"Would absolutely recommend John Mullen and his company. From the first time I called John he was very responsive and professional. I had called multiple other HVAC companies to install a vent through a brick chimney and were having trouble finding someone who would even come take a look to see if they could tackle the project. John didn't hesitate and came out and talked to us to find the right solution. Once we were ready for the job we were able to schedule him within about two weeks and he called the day of to see if they could come a bit earlier than planned. I truly appreciate the quick and professional communication throughout the whole process. The guys that came with him to do the work were also professional and they got the job done quickly. The price we paid was very reasonable for the length of time they spent and the difficult job of drilling out through brick."

"I had a fifty year old furnace that provided its last breath on the coldest day of the year and John the owner saw to it that I was financed and gave me a very good price. It was flawlessly installed the next day by his courteous staff and they hauled away the old furnace too. Great job! Thank you."

"Everything went wonderfully. After purchasing the offer, I was contacted almost immediately to set up an evaluation. They wanted to send out an employee to make sure that nothing else was needed to complete the project and he was here within a few days. I was then able to schedule the installation and it was a week later. I was contacted to ask if I was ok that the installation was pushed back a few hours due to delay in another job. They did a great job of always keeping me informed of what time they would be here. My installation, by Denny, was done quickly and professionally. He went over everything with me and made sure that I knew how the unit worked. He suggested a few things that I could have done on my furnace as well but didn't push anything on me. I found the whole process to be professional and I would absolutely use them again in the future."

      Totally impressed with this company and its technicians.   A few months ago, we had a new furnace and air condition unit installed by Air Pure.  At the time we were very satisfied with the service.  They came the same day we called and arrived the next day to install the new system.  They recently called and came out to check on the unit and make sure the a/c was working properly before the warmer weather starts, at no additional cost to us!  We will definitely recommend Air Pure. Reliable, knowledgeable, trustworthy and friendly!

Install Boiler questions, answered by experts

Due to fuel line connections and venting complexity, professional installation is required for safety and efficiency.

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.

Some high-quality steam boilers come with 10-year warranties, but a well-installed, properly maintained model can last at least 20 to 25 years. Learning how to clean a boiler, getting an annual professional service, and keeping up with maintenance and repairs on your heating system are all important for getting the most out of your model. 

Coolant and antifreeze are technically not the same thing. The difference between the two is the ratio of water to other chemicals. True antifreeze is mainly made up of either ethylene glycol or propylene glycol, while coolant comprises one part antifreeze and one part water. However, the terms coolant and antifreeze are often used interchangeably, even by pros.

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.
