"Very please with the install. Vin was very professional and applied due diligence to the project. His oversight and instruction provided the reinsurance that needed. I requested four heating and AC vendors to provide proposals. Tyler was most responsive to my questions and offered me alternatives along with helpful suggestions. My next project is my boiler. I will be turning them in the future."

Install Boiler questions, answered by experts

Most installations take 2-5 days, including old system removal and setup.

Installing a boiler requires training, a specific skill set, and extensive experience. Boiler installation can be extremely dangerous, as it involves working with water lines, gas lines, and electricity. For this reason, it’s strongly recommended that you hire a professional to install your boiler. Some states even consider it illegal to work on a boiler without the proper licensing.

If you have a closed-system boiler that requires an expansion tank, you cannot safely operate it without one, as this risks extensive damage or even explosions. You must find a way to make room for the installation. Options include repositioning the boiler, rerouting the boiler piping to a more open area, or performing minor remodeling to create the necessary space. If you are unsure whether your boiler needs an expansion tank or how to best accommodate one, it's recommended to have a local heating service professional assess the situation. They can confirm the requirement and suggest the most practical solution.

While you’ll pay more upfront for a brand-new HVAC unit, you can save money in the long run. Here’s how to save on your new HVAC system:

  • When purchasing a high-efficiency system, your energy bills will be lower in the future.

  • You may be eligible for special offers from your local energy company.

  • Depending on the system, you may be eligible for HVAC rebates and tax credits.

  • Choose to replace your air conditioning unit and furnace simultaneously to save on labor and installation costs. 

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.
