  • Median: $14,900
  • High: $20,000

What factors affect the cost of a boiler install?

The price of a boiler install varies based on three main factors: the system purchased, the need for home renovations and the contractor you hire to perform the work.

  • Boiler cost: The cost of a boiler can vary by hundreds or even thousands of dollars based on its heat output (measured in BTUs), efficiency rating (measured by its AFUE rating) fuel type (gas, oil, propane, etc.) and other factors. Even near-identical systems from two different manufacturers will share different pricing. All of this can be confusing, but an Aiello comfort consultant can help you find the perfect system for your budget in no time.
  • Home renovations: Home renovations aren't always necessary during an install. But when they are, they can add to the price. Alterations or modifications to the home's heating pipes, gas lines, oil lines or electrical system may be necessary before the boiler can be installed. For oil boilers, it may be necessary to replace an old oil tank with a new one.
  • The contractor you hire: Pricing for boiler installations vary from contractor to contractor. These rates are based on a contractor's experience, skill level, training and other factors. An improper boiler install can increase your energy bills, decrease the lifespan of your system and lead to frequent breakdowns. That's why going with a company you know will get the job done right is always the best choice.

“Thank you again for such quality work...”

“We recently had our boiler replaced. I couldn’t have asked for a better team. They were hard working from the time they arrived until they left. They worked neatly and did an excellent job on everything. We also purchased their service partner agreement. Lastly I can only say that if you want quality work and people who know what they are doing call Aiello. No matter what the job is they have the right team. Thank you again for such quality work.”
