"Never having had to hire someone to fix my AC unit only to install it (and the company was not reputable), I had serious trust issues. Action was the only one to contact me of all the suggested companies. That made me even more suspicious! They were able to fit me in for the next day. Hmm, more hesitation. But I rested in Action's good reviews on HomeAdvisor and kept the appointment. I was so happy I did. Mike was fantastic. He was personable and extremely informative. He knows his AC and heat pumps really well. I look forward to having them back in a couple of weeks to clean my furnace and do some cleaning and troubleshooting on a Hearthstone gas fireplace. When one finds a company one can trust, well, stick with them and get what needs to be done, done. I am so happy to have done something so out of my nature, like trusting HomeAdvisor. Thank you, Action Plumbing, Heating, and Airconditioning!"

"Brady and Casey are an awesome team. They came a long distance when the locals couldn't or wouldn't. They're friendly, extremely knowledgeable and if they were closer, they would be our regular furnace experts!"

"I hired TCC three weeks ago to install a heat pump mini-split systems for my 4 BR home. Their quote was competitive, their install went as planned, and the technicians were super knowledgeable and worked hard to do it right. I am thrilled with the results. I have recommended them to family already and TCC will get more business."

"While we didnt hire them, the company contacted us right away and were available within an appropriate timeline. The coordinator was friendly and reassuring and had we not had someone lined up I would have felt very comfortable moving forward with this group. They were transparent about their pricing and displayed confidence in their capabilities."

"Working with Triumph was an amazing experience. The entire team is professional, knowledgeable, efficient, and well spoken. In New England where heating is an essential service I felt totally confident Triumph would do a superb job installing my new boiler. They even moved their schedule around to install the unit the very next day. I plan to hire them in the future for all my heating, cooling, and plumbing needs."

"We were concerned with a couple of issues and they put our minds at ease.  They were professional and efficient;  George and Joe cleaned up after themselves, were very carefully to always use a drop cloth, and kept us in the loop on the installation.  If we had one area we wished that Lake Sunapee Heating would improve it would be in the area of customer communication.  However, we are more than satisfied with their work and would recommend this business.
Overall assessment:  quality workmanship at a reasonable price.

"Work with Tylor. His quality and customer responsiveness is top notch. I had him install 3 mini splits in our home. I originally wanted Mr Cool.. He coached me into upgrading to Mitsubishi for our area due to it’s significant quality increases vs Mr Cool and he was able to purchase and install faster and significantly cheaper than the “Home Depot” “Mr Cool” 3rd party install pricing company Highly recommend Tylor and his work"

"I called Gregg and he came out to survey the situation within a couple of days. He was hopeful that he might be able to bring the bathroom up to code without ripping out all the fixtures, but couldn't say for sure without actually cutting a hole in the wall in the room next door. About three days later he called to ask if his associate Donny could come out and take a look. I thought he was just going to cut the hole and then let Gregg make a final decision. Instead, Donny got the job done by mid afternoon. Not only that, he didn't leave a speck of dust even though he had to jackhammer into the foundation.
I am very pleased with the result and the price, to say nothing of the speed with which the job got done. I think it was less than two weeks from the initial call to finalizing the work.

Install Boiler questions, answered by experts

A furnace takes in cool air, heats it through the burner and heat exchanger, and sends the air on its way to warm your home. A boiler is a pressurized vessel that produces hot water or steam to heat the home and provide hot water. A boiler may or may not work together with a furnace.

While you’ll pay more upfront for a brand-new HVAC unit, you can save money in the long run. Here’s how to save on your new HVAC system:

  • When purchasing a high-efficiency system, your energy bills will be lower in the future.

  • You may be eligible for special offers from your local energy company.

  • Depending on the system, you may be eligible for HVAC rebates and tax credits.

  • Choose to replace your air conditioning unit and furnace simultaneously to save on labor and installation costs. 

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

If you hear your radiator clanking even when it’s turned off, it’s typically because there’s trapped water or air in the system, causing a pressure buildup. When you hear significant clanking, popping, crackling, or banging in a radiator that’s turned off, you’ll want to bleed the pipes or call in an HVAC specialist to deal with the problem (and prevent it from happening in the future).

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.
