Always read and understand the warranty before signing the installation contract. Most HVAC products, if not installed properly, can lead to inefficiency and premature failure.
Additionally, you will have lots of problems, including constant repairs if not installed correctly. That is especially true for boilers, even with a warranty that can still cost you money. Most HVAC warranties only cover parts and not labor. Therefore, it is crucial to hire a qualified, credible contractor for the installation — someone who knows what they are doing, especially with boilers.

A good, credible contractor will offer you their contractor warranty in addition to the manufacturer’s warranty. These types of warranties typically cover parts and labor for a term of one year. It doesn’t matter whether it is an HVAC contractor or a plumbing contractor; it is crucial to get a qualified boiler installer to do the work. Despite the manufacturer’s warranty, you will have to pay for labor. Finally, some good questions to ask about any warranty will include:

  • Will the warranty transfer to the new owner if I sell the house?
  • Who pays for shipping if the part has to be expedited?
