"I thought they were on the high side. The only problem that I've had with their delivery is, they brought oil when I didn't think I needed it. If I have a full tank in April, I don't them to come out until the fall. I don't have to be here when they deliver the oil, they show up on the day. I don't have an appointment."

"B.A.R. responded to my call right away and was able to come out the next morning. Henry was professional and great to work with. He was able to give me a good product recommendation and stayed after the product had been installed to answer any questions and make sure everything was working correctly."

"Our technician Earl was very knowledgeable. When he came back to install our 80 gallon, commercial, "Bradford White" hot water heater Norbert and another younger technician were very helpful in removing the old tank with no mess at all and taking the tank away. All 3 worked very well together to complete the install. The total time to uninstall the old and install the new was only 2 1/2 hours. Thanks to all 3 technicians, you did a GREAT job!"

"Dana was prompt and professional after I called for a quote. He was at my house within a day. The price was reasonable and he even gave a military discount! I wanted one-stop shopping, including removal of my old oil boiler and tanks including 500 gallons of heating oil, and they answered the call after another company I talked to refused to dispose of my old equipment. The installation tech, Brian W. was the consummate professional by treating my home with respect and picking up after himself by taking all garbage with him every day! The Navien Boiler install is like a work of art hanging on the basement wall and i'll proudly show it off to family and friends. The two gentlemen that came to remove my old equipment laid tarps down to keep the floors clean and didn't scratch any walls while taking out the large and heavy tanks/boiler."

Install Boiler FAQs, answered by experts

To figure out if your boiler is worth repairing or if you need to replace your boiler, first figure out how old the unit is. Boilers last 15 to 20 years, so if your unit is 15 years old or older, it may be better to replace the entire thing depending on the severity of the problems. If it’s not quite that old, then it’s probably worth repairing. Another thing to consider is whether your warranty covers any of the repair costs. If so, it may be worthwhile to repair your boiler to keep it running.

If you're often struggling with radiator issues like chilly spots, leaks, or annoying noises, those are common indications that your radiator may need to be replaced. Corrosion, uneven heating, and persistent hissing sounds are common issues as well. When repairs become a regular chore and your home’s energy bills start to rise, a new radiator will bring the comfort and savings you need.

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

If you hear your radiator clanking even when it’s turned off, it’s typically because there’s trapped water or air in the system, causing a pressure buildup. When you hear significant clanking, popping, crackling, or banging in a radiator that’s turned off, you’ll want to bleed the pipes or call in an HVAC specialist to deal with the problem (and prevent it from happening in the future).

DIY is not recommended due to safety risks and technical expertise required. Hire licensed professionals.
