"While having my siding removed and replaced, decided to insulate the exterior walls. They coordinated with the painter and checked the weather for when the project could be done. Also, the estimate was given several months in advance and was still honored once the project got going. They needed to come out twice to install the insulation because the siding took time to come off the house, but they were more than willing to work with the painter's schedule to make sure things got done in a timely fashion. Friendly folks who take time to answer questions and did excellent work getting the house insulated and now operating efficiently."

"He came in and looked at the air conditioner and the furnace and pulled out the book and calculator. He suggested me all I wanted and he gave me the best quote for it. I am happy with them. They were prompt and the guy was on time for his call. He got down to work and didn’t mess around. He didn’t try to oversell me."

"Bob and his crew arrived right on time the morning of the appointment. A couple of them began dismantling the old furnace in the basement of the house, sweeping the floor and preparing the site for the new one, while a couple others did the same with the old AC unit outside in the backyard. Only when it occurred to me that I hadn't taken the old, broken water heater into account that I asked him if he could also install a new one fo those while he was there. He gave me a fair price quote, voiced no objections about messin gup his schedule or anything, and promptly went to obtain a water heater while his workers continued with their tasks. Everything was done in a matter of a few hours and the house was cleaned up better when they left than it was before they came!  I will call Bob for each of the next houses I plan to buy and rehab, knowing that he will do just as good a job on each one as he would on his own home or my own. Bob cares about the quality of his work and it is reflected in how he does business.

"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."

"Fantastic company!!! Mammoth removed my conventional HVAC and all ductwork while upgrading my home to an energy efficient split system.... which is amazing! My entire house is comfortable, the system is great and our overall energy bills have dropped! The Mammoth team were on top of their game and I couldn’t be happier with their service."

Install Boiler FAQs, answered by experts

Unless they are connected to the same system, boilers and water heaters will both need their own expansion tanks. The only case they wouldn’t have separate expansion tanks is if the boiler is pulling double duty and managing a heating system while also supplying hot water for a home. In which case, you may not need a hot water heater.

The most important sign of a boiler problem is something happening unexpectedly, which is why regular boiler maintenance is important. Unexpected problems can include strange smells, new leaks, and unexpected noises that your boiler wasn’t making before. Additionally, if a boiler keeps shutting off or can’t maintain a specific temperature range, it’s time to call in an expert.

Coolant and antifreeze are technically not the same thing. The difference between the two is the ratio of water to other chemicals. True antifreeze is mainly made up of either ethylene glycol or propylene glycol, while coolant comprises one part antifreeze and one part water. However, the terms coolant and antifreeze are often used interchangeably, even by pros.

Oil boilers provide reliable heating, efficiency, and long-term cost savings compared to electric options.

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.
