"Great experience with Flame Tech. George was knowledgeable and responsive. He provided an accurate estimate over email based on a number of photos and a few phone conversations which streamlined the bid process considerably. They replaced my AC in a few hours for a fair price and educated me on other safety considerations related to my furnace. He also helped me diagnose a rattle in my air ducts that would have given me fits. Good price, know-how, and customer service, I would use Flame Tech again."

"

keep mold from returning.  Since I have respiratory issues, it seemed a necessary expense.  They did not have the proper light on the truck so we had to reschedule the install for a week later and that appointment also had to be rescheduled for the following day.  I was very happy with the work done, though only time will tell if it really was an issue for my health problems and I certainly know it needed to be done.  I would highly recommend this company to anyone and have done so.  I am going to write it up in the condo newsletter as something all should address and have told friends and family who have any respiratory issues about having it done.  I was told they will maintain the light every two years at no expense.  My suggestion would be that when someone is interested in booking there be more information about the possibility of needs to educate the consumers involved.  Once they are in the house doing the job it is too late to compare pricing for the work.

"Contact was made with Jason and he met with me for a free estimate of what work I wanted performed.. Jason and Chris were hired to service the Furnace and to install new H&A ducts underneath the house. Other work performed by the guys was replacing old and leaking waterlines underneath the house, and hauling away all the old ducts. Hauling an old Heating and Air unit on the side of the house, and doing some mason work to cover the hole. Installing a section of chain link fence and gate. Troubleshooting and replacing an electrical switch in the storage shed. Unclogging and replacing a waterline underneath my bathtub and installing a new shower head and fixtures. Also, repairing a leaking toilet bowl and replacing a rotting section of floor underneath..... Overall, the boys were excellent in their knowledge and work performance. They were easy to talk too and their work ethics was superb... I would without a doubt hire them again should and when the need arise..."

"I was told the week before that they would install on Monday or Thursday. On Thursday night, still no install. Friday morning about 7:30 they arrived. It took over 9 hours (not all that time spent onsite). They left 2 small pieces of trash, but it was dark by then. They didn't curse, leave a mound of cigarette butts, or make inappropriate comments that I heard."

Install Boiler FAQs, answered by experts

The primary differences between a heat pump and a boiler are their function and how they produce heat. A heat pump is a versatile system that provides both heating and cooling by moving ambient air and altering its temperature. In contrast, a boiler is solely a heating system, often working with a furnace or AC unit as part of a larger HVAC system. In terms of heat production, a heat pump generates heat more slowly and at a lower temperature, requiring a large convector for distribution. A boiler, however, produces a large amount of high-temperature heat that it emits through smaller radiators.

To figure out if your boiler is worth repairing or if you need to replace your boiler, first figure out how old the unit is. Boilers last 15 to 20 years, so if your unit is 15 years old or older, it may be better to replace the entire thing depending on the severity of the problems. If it’s not quite that old, then it’s probably worth repairing. Another thing to consider is whether your warranty covers any of the repair costs. If so, it may be worthwhile to repair your boiler to keep it running.

An expansion tank must always be installed on the supply side, which is the side where the boiler sends water out to heat the systems. That placement allows the water to push against the air and condense properly as it is heated, then circulated through the system. Professional installers can recommend the best place on the supply side for an expansion tank.

All modern boilers are condensing boilers because they’re the most efficient type. Instead of extra heat leaving through the flue, these boilers trap the heat and use it to heat the house. Whether you choose a combi boiler, system boiler, or regular boiler, you can opt to get a condensing system. If you have an old boiler that’s not a condensing boiler, it’s a good idea to get an upgrade.

Yes, government incentives and programs are available to encourage energy-efficient upgrades in many regions. These incentives may include tax credits, rebates, grants, and low-interest loans for homeowners who invest in energy-efficient improvements such as HVAC system upgrades, insulation, and efficient windows. The availability and specific details of these incentives can vary by location, so check with your local government or utility company to explore your options.
