"We were impressed with Besco from the start. We called them to replace a 20-yr old furnace and A/C. Ed came to look over our situation and found that our A/C coils had frozen, causing water to collect in the bottom of the furnace. Ed asked for towels and mopped up the 1” of water himself. The quote for new Trane equipment was reasonable compared to other quotes for similar equipment and contained 3 options. Ed got the permits for us and installation went very well. Installers efficient and explained what we needed to know. In addition to the furnace, they removed old piping from a water softener long gone. They fixed the ducts and cleaned up nicely. We look forward to having Besco maintain the new equipment."

"Our boiler went out over a holiday weekend. All Temp was quick to reply to my inquiry and quick to send someone out. Our boiler was assessed and they replaced the boiler and old pipes within a day. They were the most reasonable in town and they did an excellent job. Everyone we worked with was very professional."

"I’ve continued to hired Schavitz for all things A/C and furnace for my home due to their knowledge, honesty, and professionalism. This time met with Craig since he specializes in boiler systems and once again he exceeded my expectations with his knowledge and service. If you want complete transparency and the highest level of service then don’t hesitate to hire Schavitz. Don’t forget to ask about their membership plan.....discounts on annual services, parts, and equipment. Great deal!"

Install Boiler FAQs, answered by experts

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.

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.

Chilled water HVAC systems use water instead of traditional components and refrigerants. They're more common in commercial settings than residential ones but are slowly being adopted by some homebuilders to cool homes. As the name implies, the system keeps the water chilled at 40 degrees and circulates it through water coils. The water absorbs the heat from your home and drains outdoors. Condo apartments are more likely to have chilled water HVAC than single-family homes because this system is designed to cool several rooms or large areas individually.

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.

The primary differences between a heat pump and a boiler are their function and how they produce heat. A heat pump is a versatile system that provides both heating and cooling by moving ambient air and altering its temperature. In contrast, a boiler is solely a heating system, often working with a furnace or AC unit as part of a larger HVAC system. In terms of heat production, a heat pump generates heat more slowly and at a lower temperature, requiring a large convector for distribution. A boiler, however, produces a large amount of high-temperature heat that it emits through smaller radiators.
