"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."

"Mo is an up and coming Plumber but knows as much as someone whoâ s been in the industry for 30+ years. I had an old boiler that was 30 years old and While other plumbers tried to swindle me into purchasing a new boiler, Mo was â more than happy to take on a challenge.â To my surprise, he took on that challenge at very short notice and completed the work that same day. Some plumbers might claim that they canâ t work on the electrical part of the boiler but Mo can do both. I couldnâ t be happier. Thank you Mo!"

"Frank Green provided me an estimate for the installation of a mini-split single unit at my parentâ s home in Farmingdale. His two employees did a professional job. My parents are seniors who live with a full-time aide. They were respectful and accommodating. A day or two after the unit was installed, I reached out to Frank with questions on how to operate the unit and possibly moving it several feet. That same day, he had his employee return to my parentâ s home to discuss the matter further and to drop off another manual considered to be more user friendly which solved our issue. I would definitely recommend Just Chillinâ to other consumers."

"This team installed an oil fired boiler last month. I didn't want to give a review until our oil company said it passed their inspection which it did. They came promptly. It took all day to install. They got it working. We did have a hiccup but they came and took care of it. I was nervous to use them but so glad we chose them. Roberto and his team were great. They know their stuff. So yes I highly recommend them. See the old and new."

"Excellent Plumbing was fantastic - he installed a new faucet, vanity, and water filter for me. Super punctual, really professional, very communicative, and paid close attention to detail. Everything's working great. What really stood out was Joe's dedication. He came back to check on the work and found an unrelated issue with my kitchen sink (which was already there). He gave me some great tips on how to fix it. I highly recommend Joe and Excellent Plumbing & Heating for any plumbing work. He's super skilled and has awesome customer service."

"We were fortunate enough that we had Mike, who assisted in completing the installation of an ACiQ HVAC system that had been attempted but failed by another business. He was able in getting this highly automated, fully computerized, next-generation modell ACiQ HVAC system up and running. Iâ d like to emphasize that multiple companies refused the installation claiming that this system was too complex and they have no experience. Mike took the time to look into it, understand it and make it work. Excellent job, I would highly recommend him."

Install Boiler FAQs, answered by experts

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.

Costs depend on system size, efficiency rating, and additional features like zoning or smart controls.

Depending on the size of your home and system, as well as any upgrades or add-ons you choose, it may take between three and five days to completely replace an existing HVAC system from start to finish. Your contractor should be able to give you an estimate before they begin the actual replacement.

The best way to compare HVAC quotes is getting a few detailed quotes from local companies with good reputations. Then, go over the quotes line by line. Protect yourself by insisting on in-person estimates that include equipment manufacturer names, model numbers, SEER ratings, amounts and numbers of materials, details of warranties on equipment and labor, and other specifics. 

Knowing the exact equipment and materials is the only way that you can fairly compare quotes. Quotes that are much lower than others can be a sign that the company isn’t providing the best quality service or materials.

No, boilers and water heaters are not interchangeable because they serve different primary functions. Boilers are used for central heating systems, providing hot water or steam to heat your home. In contrast, a water heater's purpose is to supply hot water for daily household use, such as for faucets and showers. A water heater alone cannot supply the warm water or steam needed for a central heating system.

While they are not interchangeable, it is common to have both a boiler and a water heater. In fact, a conventional boiler often works best when a water heater system is already in place. The two systems can be combined to provide both heating and hot water, either by pairing a boiler with an indirect water heater or by installing a premade combination boiler-water heater unit. For home heating, some homeowners may also opt for a furnace instead of a boiler.
