"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."

"Billy and his crew were an absolutely pleasure to work with. They exceeded my expectation to replace my boiler and hot water heater along with associated piping in record time working in concert with the GC to complete all work in 3 days. The finished work was neat and clean correcting errors with my original installation. All debris was removed each day. He ensured I was satisfied, kept me informed of the progress and what to expect. Upon leaving he made recommendations to have all my air valves replaced in my radiators and encouraged me to call with any questions. I appreciate the care he and his crew took with my home."

"The installation of a new split unit Air conditioner unit was done by Joe. He installed the unit, ran the electrical work to my panel, installed all the lines needed. Joe completed the project with the expertise needed and was sure to address all the indoor and outdoor cosmetic piping and ductwork with a great appearance to meet my expectations. Joe was on time, very attentive to all my questions, emails and text messages and the price was very reasonable. I highly recommend using Joe for your AC unit installation and I will be calling him again for any future projects that I may have! 😊"

Install Boiler questions, answered by experts

When winter rolls around, and you turn the heat on for the first time in a year, it’s normal to sense a light odor. This could smell a little like burning because some dust has gathered in the heating unit over the warm months and will fade away shortly after. However, there are some smells you should watch out for and take caution around: an egg-like sulfur smell or an electrical burn odor would indicate there’s something wrong. Turn it off and call a professional for maintenance as soon as possible. 

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.

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.

Many utility companies and government programs offer rebates or incentives for the installation of high-efficiency propane boilers. These can offset upfront costs and improve your return on investment. Check with your local utility or installer for current offers. Incentives vary by state and provider, so exploring regional programs can help maximize your savings.

Most installations take 2-5 days, including old system removal and setup.
