"I had a great experience with this company installing my new boiler. Their pricing was fair compared to other estimates I received. Dave walked me through the entire process and answered all my questions, and his team came in and did a great job with the installation. With so many scammers out there, I truly felt comfortable working with this company and will absolutely use them again in the future."

"Lenny and his crew installed a new Lennox furnace for us. The team is courteous and professional. Lenny found that our old humidifier was installed at the wrong place because of the difficult duct work. He went above and beyond his responsibility and installed the new humidifier at the correct position. I greatly appreciate his honesty and utmost professionalism. It is no wonder that his company gets consistently high reviews."

"Found some water in the basement and was having some slow water drainage issues. I called up Good Tidings late in the day and Kelly was helpful and communicative in terms of expectations for service. She kept me updated throughout the afternoon in regards to availability of a service person to come out to our home. Steve arrived promptly and in the expected time frame provided. We went over the issues our home was experiencing and he clearly communicated the anticipated issue, explained the service to remedy the issue and clearly went over pricing options. He didn't push/oversell, which I appreciated, and based our favorable rapport, I also had our boiler serviced, which was handled by Matt. Both guys were great, personable, and quick with their service. We'll definitely use Good Tidings again."

"John came to my home and did his best to research the problem. He did find the answer and corrected the problem. John was very patient and concentrated on fixing the problem with the thermostat. I was very relieved to have it working again! I would recommend him to anyone needing HVAC issues. Barbara"

Install Boiler FAQs, answered by experts

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.

A furnace takes in cool air, heats it through the burner and heat exchanger, and sends the air on its way to warm your home. A boiler is a pressurized vessel that produces hot water or steam to heat the home and provide hot water. A boiler may or may not work together with a furnace.

An expansion tank must always be installed on the supply side, which is the side where the boiler sends water out to heat the systems. That placement allows the water to push against the air and condense properly as it is heated, then circulated through the system. Professional installers can recommend the best place on the supply side for an expansion tank.

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 right type of HVAC system will depend on several factors, including your climate, budget, preferences, and existing HVAC setup. For example, if you live in an area that experiences extreme weather, then a split system would likely be the best option. Or, if budget is a concern, consider installing a ductless system in just one room.
