"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 cost-efficiency of baseboard heaters depends on the type and how you use them. Generally, standard electric baseboard heaters can be expensive to run because they use electric resistance heating, which is less energy-efficient than systems like forced-air or heat pumps. However, hydronic and gas versions are typically much cheaper to operate. Hydronic models are more energy-efficient because they heat a liquid that retains warmth longer, preventing the thermostat from turning on and off as often. The overall running cost is also influenced by local electricity rates, your home's insulation, and your usage habits. To increase efficiency, you can use baseboard heaters for zoning, meaning you only heat the specific rooms you are using.

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.

Generally, an oil furnace is considered safer than a gas furnace for several reasons. While both types of furnaces can produce carbon monoxide, a leak in an oil furnace is easier to detect due to the smell. Oil furnaces also don't connect to a gas pipeline, which reduces the chance of a fuel leak. Most importantly, heating oil is not combustible, whereas natural gas is highly flammable. This means there is a much lower risk of combustion or explosion with an oil furnace. However, an oil furnace can still pose a fire hazard if it tips over.

Common problems include leaks, low pressure, and inefficient heating. Regular maintenance prevents many issues.

Using heating oil to heat your home has its advantages, but it also has its disadvantages. 

Consider these drawbacks before installing a heating oil system:

  • Heating oil prices fluctuate frequently

  • Risk of oil spills or leaks

  • Produces more air pollution and soot compared to a gas furnace

  • Regular maintenance required for equipment

  • Need to reorder heating oil consistently to avoid running out
