"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

If you go to turn it counterclockwise and it won’t turn anymore, it’s open. Like most other valves, you should be able to turn a radiator valve counterclockwise (to the left) to open it and clockwise (right) to close it. To close a radiator valve, turn it clockwise until you meet some resistance and can’t turn anymore, but do so carefully to avoid breaking the valve.

Yes. In many cases, switching from an old furnace to a high-efficiency boiler can help you save money over time. You can also save money by switching from an electric boiler to a gas boiler, which costs much less compared to the energy bills an electric boil can create. Boilers are often (but not always) more efficient than furnaces, too. Then there are discounts, rebates, and incentives that can help you save on the initial costs.

Yes. Boilers need water to run without overheating, also known as dry firing. If you run it without a sufficient volume of water, either because of a burst pipe or a leak, you run the risk of damaging your machine or jeopardizing the safety of your home as a whole. When in doubt, shut off your boiler and repair any plumbing issues before turning it back on. Alternatively, consider installing a low-water cutoff (LWCO) before any issues arise. This gadget will protect your boiler by monitoring water levels and automatically shutting it off if it gets too low. 

A common HVAC rule is that for every 500 to 600 square feet of living space, you need 1 ton of heating or cooling capacity. Now that you know this common rule, you also need to know that it isn’t very accurate, and a dedicated pro wouldn’t use it for your home. If you talk to a pro who won’t or can’t perform a proper Manual J calculation, consider hiring someone more thorough.

The right type of HVAC system will depend on several factors, including your climate, budget, preferences, and existing HVAC setup. For example, if you live in an area that experiences extreme weather, then a split system would likely be the best option. Or, if budget is a concern, consider installing a ductless system in just one room.
