"I couldn’t be more pleased that I chose Gen3 to replace my “very old gas boiler/heater” Large purchases always make me nervous but Nicole Curran went above and beyond in explaining everything from start to finish in layman’s terms, to help ease my anxiety. Both Nicole & Travis were prompt, professional & friendly throughout the install. My many questions were met with quick response from the office staff, both Lauren and Heather are pleasure to work with. Do not hesitate to call Gen3 for your heating or cooling service needs."

"Overestimated the time to complete an 9 hr job by scheduling a 16 hr window (2 guys x 8 hrs) and charged for 16 hrs regardless. I'd imagine they did the same for the materials, 60 feet of duct needed but they quoted 200. Got the job done, but probably twice the price of what it should have been."

Customers say: Quick response

"I have a maintenance contract. Today Fabian came out. He was very thorough. He spent two hours at my condo performing all kinds of tests. Before he left he went over things I could do to get better performance from my heater. I appreciate the fact that he did not try to pressure me into picking something. He emailed me (while in the truck) options and also explained different ways to pay for it. He noticed the oxygen in my home. My husband had CHF and COPD so I was specifically interested in the ways I can help his breathing better. I believe in todayâ s environment itâ s difficult for companies to get really good employees. This young man , 20, had a great work ethic and a bright future. Very pleased with the service I have received. Thank you Harris."

"We were delighted with our generator project. Everyone from Sunrise Comfort Solutions was so genuinely focused on making certain that our selection, installation, and generator operation exceeded our expectations. Covid protocols were practiced. Selection of a properly sized generator is the key to your satisfaction when it's needed. Your sale exec will conduct a thorough evaluation of tour home systems. Installation is a complex process; done with expertise. Testing and homeowner in- service were a cinch. Service does not end with the installation. The contractor followed up to ensure our questions were all answered. Communications were excellent throughout the process. I look forward to working with Sunrise Comfort on future projects at our home."

Install Boiler FAQs, answered by experts

Costs range from $3,000 to $7,500, depending on system size and efficiency.

The cost of heating oil fluctuates rapidly based on supply and demand, but the average price is between $4.00 and $4.50 per gallon, which means filling a standard 275-gallon tank would cost between $1,100 and $1,240. Much like automotive gasoline, the price of home heating oil changes constantly, so the only way to get an accurate and current price per gallon is to contact a heating oil delivery company. Some companies also offer contracts with a set price that should be an average cost over the contract term.

Yes, you can build a sunroom addition to your home despite living in a cold climate. Make sure to use high-quality insulation and windows and to supplement with sufficient heating from your HVAC system. The windows in the sunroom allow enough natural light into the room to help heat it most times without having to use the furnace. Even a small electric fireplace can heat the sunroom well enough.

It can take anywhere from four hours to three days to replace a boiler with a new one. How long your particular boiler installation takes will depend on whether you need a gas line installed and if you’re switching to a new boiler system. 

Replacing a combination boiler or standard boiler with the same system should only take four to six hours. Meanwhile, switching from a conventional boiler system to a combination boiler system could take a few days.

Overall, heating your home with an oil furnace tends to be less expensive than heating your home with an electric heating system. Oil heating systems stay warm for longer periods of time without drawing a constant electrical current to maintain a temperature. Plus, heating oil systems typically have a longer lifespan and lower price tag than their electrical counterparts, resulting in short- and long-term savings.
