"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."

"Did a really great job fixing my boiler. Went completely out of his way to get the part I needed so I can have restored hot water the day of service. Super nice and informative guy too. I would hire this company for anything."

"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!"

"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."

"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."

"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 questions, answered by experts

It takes about five to 10 minutes for heat to reach a radiator, then about one hour until the radiator fully heats up a room. The exact duration depends on the size of the room and how far away the radiator is from the boiler heating system. Heating up an entire house could take up to two hours.

Most home boilers will need an expansion tank. That’s because these boilers are closed-loop systems, where the water is trapped. An expansion tank is needed when the boiler heats the water and it expands, allowing air to condense in the tank to make room for the water. Other types of boilers don’t use an expansion tank, such as traditional steam boilers, but these aren’t as common. And hot water tanks may be able to use a pressure release valve instead. When in doubt, call in a pro to take a look.

A furnace is a big unit where gas, heating oil, or electricity heats the air. The warmed air is then pushed back out through ducts and vents. 

A boiler uses electricity, heating oil, or gas to heat water that is pushed into the room through a radiator. This is one of the oldest and most effective ways to heat a house, but radiators can also be unsightly and leave hot and cold spots in the room.

Heat pumps use a refrigerant to move heat from outside into the house and return it to the room through ducts and vents.

While you’ll pay more upfront for a brand-new HVAC unit, you can save money in the long run. Here’s how to save on your new HVAC system:

  • When purchasing a high-efficiency system, your energy bills will be lower in the future.

  • You may be eligible for special offers from your local energy company.

  • Depending on the system, you may be eligible for HVAC rebates and tax credits.

  • Choose to replace your air conditioning unit and furnace simultaneously to save on labor and installation costs. 

The absence of heating or hot water, unusual noises like banging or gurgling, and visible water leakage are key signs. Abnormal boiler pressure, flame irregularities (for gas boilers), or pilot light issues may also signal trouble. Frequent cycling, soot or staining, and unusual odors, particularly gas-like smells, should not be ignored. Modern boilers often display error codes or lockout mode upon detecting issues. Uneven heating across radiators and rising energy bills without increased usage can further point to problems. Prompt attention to these signs is essential to prevent further damage and ensure safety.
