"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."

"After buying a new refrigerator, Home Depot told me I needed a plumber to run a new water line to the refrigerator. I was not happy with the Home Depot tech that called me. The plumber, Dave, arrived soon after I called Harris and did a phenomenal job! He was friendly, professional and worked quickly. Thank you, Dave, and Harris Plumbing!!"

"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

Always consult your manual for specific pressure numbers. Many expansion tanks come pre-pressurized at a specific PSI range, anywhere from 12 to 40 PSI, designed for a range of home boilers. You should not have to pressurize an expansion tank yourself, only the boiler system. If your system has a tank that needs to be manually pressurized, this is generally a job for professionals and their tools.

No, boilers and water heaters are not interchangeable because they serve different primary functions. Boilers are used for central heating systems, providing hot water or steam to heat your home. In contrast, a water heater's purpose is to supply hot water for daily household use, such as for faucets and showers. A water heater alone cannot supply the warm water or steam needed for a central heating system.

While they are not interchangeable, it is common to have both a boiler and a water heater. In fact, a conventional boiler often works best when a water heater system is already in place. The two systems can be combined to provide both heating and hot water, either by pairing a boiler with an indirect water heater or by installing a premade combination boiler-water heater unit. For home heating, some homeowners may also opt for a furnace instead of a boiler.

Many HVAC companies offer free quotes and free estimates for repairs and new HVAC systems. Others offer low-cost quotes or apply the cost of the estimates or diagnostics to your final bill if you hire them. Be aware that some companies advertise free HVAC quotes and recoup the costs by charging more for their services. Free HVAC quotes are never truly free—they cost the company time and effort—so be a good customer. Also understand that you may end up paying for free quotes in another way if you don’t hire a reputable company.

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.

Most propane boilers last 15 to 20 years with regular maintenance and proper care. The lifespan depends on the quality of the unit, proper installation, and the level of maintenance. Investing in annual service can maximize longevity and efficiency. Routine inspections and timely repairs prevent early breakdown, ensuring your boiler heats your home for years to come.
