"Luckily our heater waited for us to wake up on a Friday morning before conking out. I thought we might be able to make it through the weekend, but when it looked like that wasn't going to happen, they had someone out later that day for us. Fixed the heater, kept the costs down. I could only imagine al the things it _could_ have been. So impressed we signed upt for their regular maintenance plan right there.

"They were very professional in presenting various options for the installation. The time between order and install was then 36 hours, and day of install the crew arrived on time and completed with the scheduled time frame. Mr. Ashby personally did a follow-up visit to ensure our satisfaction. We would without question hire them again."

"There was very little work to do. They came out on time and I was happy for the professionalism, but there was nothing to do because it's a brand new system. The service is free for a year. I could have had them come out in April to check the air conditioning system, but since they just installed the unit in April, I didn't bother, but it would have been free. This fall, when I called him to check the furnace, he thought he was coming out to check the air conditioning, I said, "no, you're here to check the furnace because I'm going to be using the heat this fall". He said, "no problem" and he checked that out, he said, "I feel like I'm not doing anything, I can still check the air conditioner", and I said, "if you want to, but I've been running it all summer and it's been great". I asked him there was a charge and he said, "no, the first year was free"."

Install Boiler FAQs, answered by experts

If you’re looking for a way to heat your home that is lower in cost and higher in efficiency, you should run the numbers to see what it would look like to switch to gas or electric heat. The best choice for how to heat your home depends on your location, budget, and energy priorities.

Yes, most municipalities require a permit for propane boiler installation to ensure safety and code compliance. Permit fees vary by location and are often included in your installer’s quote, as they’ll handle the permitting process. Ensure that you always check local regulations before starting your project to avoid fines or delays.

Some high-quality steam boilers come with 10-year warranties, but a well-installed, properly maintained model can last at least 20 to 25 years. Learning how to clean a boiler, getting an annual professional service, and keeping up with maintenance and repairs on your heating system are all important for getting the most out of your model. 

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.

Yes. In many cases, switching from an old furnace to a high-efficiency boiler can help you save money over time. You can also save money by switching from an electric boiler to a gas boiler, which costs much less compared to the energy bills an electric boil can create. Boilers are often (but not always) more efficient than furnaces, too. Then there are discounts, rebates, and incentives that can help you save on the initial costs.
