"I was very happy with my experience using this company. In the middle of a heat wave, right before the July 4th holiday, my AC stopped working. The man who installed it and had been servicing it was too busy to come for a week. I called MSD and was given an appointment for 8 AM the next morning. They were prompt and courteous, fixed my problem, and were reasonably priced. I will be calling them in the future."

"Kevin was great! The rest of the company not so much. Kevin diagnosed the problem immediately as the thermostat, had a replacement in the truck, and completed the installation of the new unit quickly. He showed me how to program the updated version, and everything seemed to be fine - until the next morning. Turned out the replacement was defective. When I called, I was told that they might not be able to get back to me that day, but Kevin interrupted his schedule to come back and put in a new (and working) unit at no charge."

"Extremely satisfied & pleased with the work performed by Elm. Eric, Rob & Jesse were great on the installation – on time, neat, careful to show us the status as they went through the job. Have already recommended Elm to neighbors who expressed interest. Scott was great on the initial review & estimate & Cathy in the office was extremely helpful as well. Thank you to the whole Elm Team!"

"Repairman, Andrew, came and located the problem. The ignitor had burned out, so the burners would not light. Andrew did not have the part in his truck but was able to fit in a used part from another furnace to give me heat until he got the other part. I got a call the next day and scheduled a time to put in the exact part. Again, repairman was within the stated time window. Heat working well."

"Ken did an outstanding job installing our new furnace and chimney liner. Ken had previously done several smaller plumbing jobs for us, giving us great confidence that he?d do a great job installing our new furnace and liner. He didn?t disappoint us. You can tell that Ken takes great pride in his work, and we felt that at every turn, he went above and beyond for us. He carefully thought out what needed to be done, and he patiently explained his plan to us. Ken worked well into the evening to get our heat on as soon as possible. He kept us up-to-date on the progress, and when the installation was complete, he took the time to explain how the new system works. Ken is a pro. He is personable, knowledgeable, hardworking, even-tempered, responsive, and dependable. We will continue working with Ken, and without any reservation we highly recommend him.

Install Boiler FAQs, answered by experts

Deciding whether or not to replace radiators with a different heating system depends on your personal preferences. Radiators can take longer to heat up than a central heating system, and they take up floor space. However, they can be very efficient at heating, and they keep rooms at a more comfortable humidity level in the winter than forced-air systems.

You can use a boiler and a furnace, although it’s not common to use both for whole-house heating. For example, your furnace may take care of HVAC heating through your vents, while a boiler powers your floor-based radiant heating in the bathrooms. Mixing and matching like this gives homeowners a variety of heating possibilities.

The average cost to replace or install a new HVAC system is around $7,500. However, the price can range from $5,000 to $12,500, depending on factors like the size of your home, the type and brand of the unit, and your specific heating and cooling needs. If you only need to replace certain components, the cost will be lower; for example, a new AC unit can cost between $2,200 and $5,500, while a new furnace costs $3,200 to $6,000. If additional work like new ductwork is required, the total cost could be as high as $22,000. It's best to contact a local HVAC company for an accurate quote.

The cost to install a steam boiler varies depending on the type, fuel used, and your house size. The average cost to install a boiler is $5,900. You could spend $2,000 for a basic electrical steam boiler or up to $9,000 for a high-efficiency oil-burning steam boiler. Boiler installation is a job that’s best left for professionals to complete, and, in some states, only licensed installers can legally complete the job.

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.
