"HARP sent a rep to the house, he did the evaluation for sizing, which was in line with the sizing tools I used. The solution he offered was just about what I had picked out, and I went with his recommendation. The install went fine. They did have to be reminded to retape some ducts, but we're happy to take care of it."

"great. Jesse was super smart, friendly, conscientious and knowledgable. he spotted a few things the previous tech didnt (including inefficiencies which were likely costing us money in propane costs). our boiler was super dirty and he got it looking and working as good as new (better actually as it wasn't set up correctly by the original home owner!). he put our mind at ease with his clear articulate explanation of what was needed and how he solved the problem. hopefully we get jesse again for next year's service. looking forward to a warm, cozy, efficient home this winter. thank you Jesse and Beacon!"

Install Boiler questions, answered by experts

Boiler installations and replacements cost between $3,600 to $8,400. Expect to pay around $5,900 on average for a new boiler, including installation. Adding new radiators or heaters to the boiler may include separate costs if you are also upgrading those components, so the final price may be higher. To decrease costs, you can look for local energy rebates for using a boiler and wait until installers are offering discounts for a first-time installation.

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. 

Most experts recommend getting three to five HVAC quotes from licensed, insured, reputable local heating and cooling companies. Getting multiple detailed HVAC quotes (but not too many) lets you compare the equipment, services, and prices of several contractors without being overwhelmed by options. It can also let you see if one contractor’s prices are much higher or lower than the others and give you a chance to ask for clarification. That way, you can weed out any contractors who aren’t providing quality services or materials and find the company that best meets your budget, quality requirements, and long-term goals.

In some cases, conversion kits are available, but not all boilers are compatible. Conversion may require significant modifications and should only be performed by a qualified professional. Before making a decision, compare conversion costs to the cost of a complete replacement to determine the most cost-effective and reliable option for your home.

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