"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!"

"I finally got to build my dream garage to store all my tools and have a cool hangout on Friday nights with the boys n a couple coors. Chris came and did everything from the bathroom and the heating system. I will definitely be calling him back to add a mini split in the future. He was professional, punctual and clean. Very knowledgeable you can tell he cares about his clients."

"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.

"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.

"Jim with North Alabama Technical Services removed some items from my computer so that I could send emails and attend to items I needed to address that day. As planned, the next day he thoroughly cleaned my computer, he also made helpful suggestions while working on my computer. I would call him again if needed and I thought the fee was reasonable."

"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"

Install Boiler questions, answered by experts

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.

Generally, an oil furnace is considered safer than a gas furnace for several reasons. While both types of furnaces can produce carbon monoxide, a leak in an oil furnace is easier to detect due to the smell. Oil furnaces also don't connect to a gas pipeline, which reduces the chance of a fuel leak. Most importantly, heating oil is not combustible, whereas natural gas is highly flammable. This means there is a much lower risk of combustion or explosion with an oil furnace. However, an oil furnace can still pose a fire hazard if it tips over.

Deciding whether or not to replace radiators with a different heating system depends on your personal preferences. Radiators can take longer to heat up than a central heating system, and they take up floor space. However, they can be very efficient at heating, and they keep rooms at a more comfortable humidity level in the winter than forced-air systems.

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).

Boilers are equipped with multiple safety features to ensure safe operation. These include pressure relief valves to prevent overpressure, temperature high-limit switches to avoid overheating, and flame failure safety devices in gas boilers to cut off the gas supply if the flame goes out unexpectedly. Low water cutoffs prevent operation with insufficient water levels, and pressure gauges help monitor pressure levels. Ventilation and flue systems prevent the buildup of harmful gasses. Boilers often feature error code systems for automatic shutdown during malfunctions and gas leak detection for safety. Regular maintenance is crucial to ensure these safety features function correctly.
