"I called Mehmet based on the Angie's list recommendation and the terrific reviews. Mehmet worked around my work schedule and came after 5. He identified the problem and installed a new capasitor. He was in and out of here in 30 mins. A week earlier a rip/off big company (Varsity) claimed the unit could not be fixed for under $3500 and recommended I install a whole new system for $11,000. Mehmet's skill, reasonable price and honesty were well appreciated here."

"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."

"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."

Install Boiler questions, answered by experts

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.

Boilers provide even heating, energy efficiency, and a quiet operation compared to forced air systems.

The best time of year to purchase or replace an HVAC system, including components like an air conditioner or furnace, is during the off-season—spring and fall. During these periods, HVAC professionals are less busy than in summer and winter, when extreme temperatures create urgent demand. Shopping during the off-season can lead to savings of 10% to 15% on an AC unit and allows you more time to find the best deal and other cost-saving incentives. Typically, air conditioning units go on sale in the fall after demand drops, while furnace prices tend to decrease in the spring.

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.

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.
