"Joe, the AirCo sales representative, was very professional. He actually asked for my feedback on priorities for a new boiler. This was important to me because the boiler sits below our family room, and the noise level of the boiler was as issue. His proposals listed several boiler options, based on heating efficiency, which were competitively priced. The installation was run by Steve, who was able to fit in the installation the next week. Steve, and his crews, were punctual and courteous, and the installation went smoothly. It's only been a week, but I am very pleased with my Bosch boiler, the quality of the work, the price paid, and the timeliness of the installation."

"We've used Atlantic Heating & AC for many years and wouldn't consider any other company. Atlantic is extremely responsive, priced reasonably, and they always do a great job. We've never once had to call them back to resolve any issues associated with their work, and they've done a lot of work over for us over the last 9 years. Recently, our water heater died very suddenly; I came home from my office and water was leaking out of the water heater onto the basement floor. Within minutes, their service manager was guiding me over the phone regarding which valves to turn off etc. and he had me take a few pics to send to him. The very next day, a serviceman was at our house installing a brand new, much better water heater than the house had come with, and we haven't had an issue yet, and this was several months ago. I'm a Realtor and Atlantic has bailed my seller clients out of HVAC issues on a moment's notice, so I will always be grateful for the excellent sales and service that we receive thanks to Atlantic Heating and AC."

Install Boiler FAQs, answered by experts

The cost of propane and related services varies depending on tank size and location but generally ranges from $500 to $2,500 for installation and initial fill.

The most important sign of a boiler problem is something happening unexpectedly, which is why regular boiler maintenance is important. Unexpected problems can include strange smells, new leaks, and unexpected noises that your boiler wasn’t making before. Additionally, if a boiler keeps shutting off or can’t maintain a specific temperature range, it’s time to call in an expert.

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.

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.

One of the easiest ways to determine which type of furnace will work best for your home is to contact a professional in your area. Many HVAC companies offer free consultations to help potential customers determine if they need a new system and which type would work best for their home and the community’s climate.
