"We contracted Cencal to install a new HVAC system over the summer based on their strong reputation on Yelp. They went above and beyond exceeding my expectations on everything from planning, to implementation to customer service. This is probably one of the best contractors I have ever worked with. You can be confident in choosing them over competitors for your HVAC needs. I will be using them again for any future HVAC needs."

"Exceptional product and service, Long's Air Heating and Cooling put in a system that is more effective and efficient for my home than was installed previously. They arrived as scheduled and where professional and courteous. Cleaned up everything nicely. I have already recommended them to family and friends and will continue recommending them. P.S. Long's also provides a twice yearly maintenance with the first years maintenance free. Thanks Jordan"

"Jim did a great job. He quickly assessed the problem and then took our unit with him to work on it more. When he got back to us, the fix would have cost more than it was worth. He gave us options for a new or refurbished PC. We felt the refurbished was a good deal and chose that. He came back and set that up and we are very happy with it. He then took a look at my laptop and again took it along. He tuned it up and installed a speed upgrade we wanted. Of course, we paid extra for the new unit and upgrades, but we thought the price was very fair. Jim seemed very knowledgeable and responsive. We will definitely call him again if we need any computer services."

"At first it went well. The technicians were professional. They said the install would take 2 1/2 days. The first two days were fine. They asked if they could change the date to finish the install and we said yes. They came for the final 1/2 day of work which turned into a whole day. Early in the afternoon, one technician said he had to leave early. No problem. The other two technicians said they could finish. It went on and on. The two technicians could not figure out how to wire in the thermostat, and they finally gave up. The heat would turn on, but never turn off by itself. My mom had to keep getting up in the middle of the night to turn the unit on and off again to keep from freezing or sweating like in a sauna. They said they would be back the next day to install a simple thermostat and have everything working correctly. .they did not return. Everytime I called the technicians would tell me they were working on roofing jobs for other customers that had to be finished immediately because it was going to rain. After two weeks of this ********, I put my foot down and said I wanted my parent's job finished. Two technicians came out one more time and installed a new, very simple looking thermostat. I thought everything was great and thanked them, only to find out a year later that the new thermostat had also been wired incorrectly and would not come on or shut off on its own. This was the first time my mother has ever had central heat and air. She didn't realize that the thermostat wasn't working properly, and I didn't find this out for an entire year. My mother had a schedule posted on her bedroom wall reminding her when to turn on and off the unit to keep the temperature comfortable. Needless to say, I was ******. I called and asked the company once again to fix the problem. This time they sent out Amoz Marshsll. He was knowledgeable, professional and polite. He fixed the wiring problem in 15 minutes, apologized for it being done incorrectly the first two times and left. He was amazing. I wish he had installed the original unit."

Install Boiler FAQs, answered by experts

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

The cost to install a steam boiler varies depending on the type, fuel used, and your house size. The average cost to install a boiler is $5,900. You could spend $2,000 for a basic electrical steam boiler or up to $9,000 for a high-efficiency oil-burning steam boiler. Boiler installation is a job that’s best left for professionals to complete, and, in some states, only licensed installers can legally complete the job.

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.

Professionals can recommend efficient layouts or appliances and ensuring regulatory compliance.

The cost of propane and related services varies depending on tank size and location but generally ranges from $500 to $2,500 for installation and initial fill.
