"We had a leaking 35 year old oil-fired boiler that needed to be replaced. This was just at the start of the heating season in 2021. We got quotes for price & installation dates from several HVAC companies Clear All HVAC supplied several boiler replacement options and also quoted an earlier delivery date than any other quote. We selected a boiler/indirect water heater combination that was significantly less than competing quotes. Clear All installed the system within a week and responded quickly to any concerns & questions we had. We highly recommend Clear All HVAC for anyone that needs HVAC installations, repairs, service and values good customer service. In our opinion they are outstanding and we will continue to use them as our go to HVAC Services company."

"Highly recommend Joe! 30 yr old boiler died, leaving us with no hot water. Joe quickly came and provided quote for boiler and new Indirect water tank which we wanted replaced. His price was a lot more reasonable than other quotes I got. also was able to get project done the same week as quote where others were scheduling 1 to 2 weeks out. despite the supply house delivering the boiler late ( Joe stayed in contact advising progress) He still was able to complete the work when he said he would. Top notch guy, Fair and honest. finished project looks great and works as advertised! Have more work for him to do"

"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!"

"Kason is truly the best. Not only does he answer every time we call for any issue, but he or Connor, show up the same day which is huge when you run a small business! We needed a walk in freezer repair at our catering business- Kason was there on Wednesday to investigate, called me the same day with an estimate and we had the install on Friday. He is meticulous, precise and very knowledgeable. Kason has checked in the last few days to make sure things are still running smoothly and the freezer is doing its job- where can you find better customer service? I know we are a CRS Mechanical customer for life now."

"East Coast Plumbing and Heating provided us with a great service on a big job of replacing our 30 years old furnace. Dylan was very accommodating and explained the process in a great detail. His estimate for the job was honest and fair. Dylan and his crew did the job in one day and did an excellent work for a reasonable price. We are very happy with this company and we will work with them in the future. I highly recommend East Coast Plumbing and Heating."

"I am writing to express my deep disappointment with the service provided by McGinley & Sons. Despite multiple attempts to resolve this issue, I have yet to receive the promised refund for work that was never completed. As a cancer survivor undergoing surveillance scans, the refund would greatly assist in covering my medical expenses. The lack of response and follow-through has added unnecessary stress during an already difficult time. In addition to this, I had to hire a lawyer to recover my down payment, which cost me additional money. Moreover, he did not offer to compensate me for the extra expenses, including hiring an electrician to install a wire for the heat pump he could not install. Despite repeated attempts to have the deposit returned, I finally received it after engaging legal assistance. I hope this review will encourage McGinley & Sons to address this matter promptly and fairly."

"TCC is as good as it gets. After several issues with our GC and the plumber he used, I insisted that we use ours to fix everything that was messed up and/or flat-out wrong in our house. He agreed and I immediately called TCC. First, Joe is the best when it comes to boilers and plumbing issues. He is extremely knowledgeable and very patient when someone like myself, who knows absolutely nothing about boilers, ask a LOT of dumb questions. He fixed an issue that we've been having since we moved into the house last summer - one that our GC's plumber has been to the house on three different occasions to fix and only made worse. I've recommended TCC to clients who needed boiler repairs, plumbing updates and such in their homes and all have been equally as pleased. Are they cheapest around? No. But I've found that, when it comes to contractors, you get what you pay for and if paying a little more means I'll have good service and it'll be done right the first time, then I'll pay it every time. TCC rocks!"

Install Boiler questions, answered by experts

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.

If you want to have hot water in your home and part of your plumbing system, you'll need a hot water heater. An alternative may be to heat water as you use it, such as by boiling what you need on the stove. But that's much less efficient and takes considerably longer than hooking up a water heater. Another option is to rely on appliances, such as a dishwasher or washing machine, that heat the water themselves.

Since your boiler keeps you warm and provides hot water to your home, you’re likely to notice issues with heating in your living space right away. The most obvious sign that your boiler is breaking is not getting any heat or hot water. You might also hear some odd sounds coming from your boiler during operation, the flame in your gas boiler is not blue, the pressure is inconsistent, or your boiler is using more energy than it should. If you notice any of these signs, be sure to call a pro right away.

When winter rolls around, and you turn the heat on for the first time in a year, it’s normal to sense a light odor. This could smell a little like burning because some dust has gathered in the heating unit over the warm months and will fade away shortly after. However, there are some smells you should watch out for and take caution around: an egg-like sulfur smell or an electrical burn odor would indicate there’s something wrong. Turn it off and call a professional for maintenance as soon as possible. 

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.
