"Brady from Maine Way Heating & Cooling. The gentleman came when expected, very pleasant and knowledgeable. His quoted price was very reasonable and less expensive then the company we used last year. He did find that we needed another part to complete the job he was not pushy about selling it and stated we could schedule an appointment. After talking with him we asked him to go ahead and fix it. This gentleman is very professional and very upfront with his price ...We will for sure call him again next year for service and with any emergencies we may have. Thank You Brady!!"

"This business is excellent. We received three quotes from various businesses and D&M was the only reasonable one. The installation was done in a timely manner. The owner did an exceptional job and was both professional and efficient. Based on his service, we have decided that from now on, all service for all boiler will be done by this organization. You cannot go wrong with D&M. I highly recommend him!"

Install Boiler FAQs, answered by experts

Yes, most municipalities require a permit for propane boiler installation to ensure safety and code compliance. Permit fees vary by location and are often included in your installer’s quote, as they’ll handle the permitting process. Ensure that you always check local regulations before starting your project to avoid fines or delays.

Chilled water HVAC systems use water instead of traditional components and refrigerants. They're more common in commercial settings than residential ones but are slowly being adopted by some homebuilders to cool homes. As the name implies, the system keeps the water chilled at 40 degrees and circulates it through water coils. The water absorbs the heat from your home and drains outdoors. Condo apartments are more likely to have chilled water HVAC than single-family homes because this system is designed to cool several rooms or large areas individually.

Unless they are connected to the same system, boilers and water heaters will both need their own expansion tanks. The only case they wouldn’t have separate expansion tanks is if the boiler is pulling double duty and managing a heating system while also supplying hot water for a home. In which case, you may not need a hot water heater.

Always consult your manual for specific pressure numbers. Many expansion tanks come pre-pressurized at a specific PSI range, anywhere from 12 to 40 PSI, designed for a range of home boilers. You should not have to pressurize an expansion tank yourself, only the boiler system. If your system has a tank that needs to be manually pressurized, this is generally a job for professionals and their tools.

It can take anywhere from four hours to three days to replace a boiler with a new one. How long your particular boiler installation takes will depend on whether you need a gas line installed and if you’re switching to a new boiler system. 

Replacing a combination boiler or standard boiler with the same system should only take four to six hours. Meanwhile, switching from a conventional boiler system to a combination boiler system could take a few days.
