"Everything done exactly right, on schedule (ahead of what I was expecting). AJB quoted a Columbia boiler, which cost a little more than the others, but I believe will be worth it. Worked almost 13 hours the first day and a couple more the next day to get the job done. Cleaned the area and ensured everything was operating properly."

"This company came highly recommended, as many of today's technicians cannot service traditional "steam" boiler systems. Ever since last year's "furnace emergency", this "Old House" here found "its rescue match" with Pohlman Plumbing & CJ, a highly skilled specialist, who tweaked the boiler back to "steam". Explaining why my Amish-built "Oldie-Goldie" was here to last, CJ enjoyed "challenges" & was not trying to "up-sell". This positive experience of transparency & trust convinced us that we'd found "the" company for all our "Old House" future HVAC & plumbing needs, thx!"

"I had a good experience with Mr Lowery. He was on time to fix our heater, performed the service with clear expertise, explained everything in detail and gave a ton of advice on both AC and heater maintenance. Following his visit the heater performed much better. Very satisfied with the service. Would recommend Lowery Heating any day."

"This review should probably be three separate reviews, but I think it shows my trust in Vernon using him multiple times. He came out to give me a quote on a new gas water heater and relocating it about 8 feet over in the basement. The price was reasonable and he provided me the water heater information so I could see it's reviews beforehand. While installing my water heater, my tenant called and said the AC was not working. So, after completing the install and his other stops that day, Vernon went over later that day to take a look. The repair required a new part, so a few days later he repaired the AC and I had him replace a leaking pressure valve while he was there. About a month later, a house I renovated needed some repair work on a leaky drain before settlement (he was not the initial installer). Vernon went into that crawlspace and repaired the pipe and provided the appropriate documentation so we could get to settlement in time. I had Hamilton Plumbing and HVAC do work at my home, my rental, and then my house flip. I plan to have Vernon come back to run a gas line when I install a gas fireplace and again when I do my basement bathroom."

"Don (the owner of Aqua) was in the area at the time I called and was able to stop by within 60-90 minutes of my call. He checked operation of the boiler, and diagnosed the problem with the help of the boiler manufacturer tech support. I needed a new ignition control module; the problem was that the boiler flame would not stay lit. He tried to get the old one working again, and seemed to succeed, but I called him back the next morning to report it started acting up again. He ordered the part and returned after it arrived in a few days to install it. The part appeared to resolve the issue and I was good to go. The boiler is over 25 years old and my previous HVAC contractor had said it needed to be replaced. Don looked at me like I was nuts when I told him that. He genuinely believed in repairing rather than replacing if at all possible, and I could not agree more."

Install Boiler FAQs, answered by experts

Professional HVAC installation requires licensed expertise in several areas, including electrical- and plumbing-related work. An HVAC team must know how to safely handle regulated refrigerant chemicals and the gas, oil, or propane used in furnaces and boilers. A proper HVAC installation protects your home from energy loss, fires, and even carbon monoxide leaks.

It takes about five to 10 minutes for heat to reach a radiator, then about one hour until the radiator fully heats up a room. The exact duration depends on the size of the room and how far away the radiator is from the boiler heating system. Heating up an entire house could take up to two hours.

Many HVAC companies offer free quotes and free estimates for repairs and new HVAC systems. Others offer low-cost quotes or apply the cost of the estimates or diagnostics to your final bill if you hire them. Be aware that some companies advertise free HVAC quotes and recoup the costs by charging more for their services. Free HVAC quotes are never truly free—they cost the company time and effort—so be a good customer. Also understand that you may end up paying for free quotes in another way if you don’t hire a reputable company.

Heat pumps are significantly more efficient than boilers, typically providing three to four times the amount of heat for the electricity they consume. While boilers run on fossil fuels, heat pumps use only electricity. This efficiency can lead to long-term savings on operating and maintenance costs. However, heat pumps have a higher upfront installation price compared to boilers. Despite their lower efficiency, boilers remain a popular choice for many homeowners, with 8 million in the United States alone, due to their lower initial cost and less intensive installation process. Ultimately, the best choice depends on your home's infrastructure, your budget, and your personal heating priorities.

There are several types of home radiators, and the most common are steam heat radiators, electric radiators, and dual-fuel radiators. Steam heat radiators are connected to a boiler. Electric radiators can operate without being connected to anything else—they just need an electrical outlet. If you have a dual-fuel radiator, you’ll see a valve at the bottom of the system with a wire coming out of it and going into a wall. These are often your towel radiators in the bathroom. The type of radiator you have will impact how you turn it on.
