"Williams & Associates installed a Buderus oil-fired boiler and stainless-steel chimney liner. Bruce's design was a significant upgrade over my 35-year-old boiler system. He clearly explained the process and installation, and he was receptive to my questions. Bruce is knowledgeable, straightforward, and responsive. The price was very fair, considering the quality of the work and other estimates I had gotten. I would not hesitate to recommend Williams & Associates."

"Mull Brothers gave us an estimate on installation of central air conditioner in our old home.  Their price was slightly higher than some competitors (although not by very much), so we didn't end up using them.  However, I was very impressed with Mr. Mull's visit.  He was knowledgeable and thorough, and gave me great information without using any high-pressure sales tactics.  I will probably contact them again in the future for my next project.

"Pete, Jake and Jeremy and a couple of other workers from Cool Heat Mechanical did a great job on installing 3 central air conditioners and air handlers at my house over a 3 day period. They were neat, clean, on-time and did an excellent job installing the American Standard A/C and air handlers. The units are running great and improved my energy efficiency tremendously over my older units. Pete is extremely knowledgeable with his profession of installing A/C and heating systems. His pricing is excellent as well. We are also using them to install a new heating system within the next few weeks. We initially met with Dave who reviewed their products and gave us the pricing for the job. Dave made an excellent presentation of all their products and did not use any high pressure selling tactics. He offered some nice financing options through EnergizeCT that I was not aware of as well. I did have multiple vendors competing for the job and found that Cool Heat Mechanical was the most knowledgeable and had the best products and pricing in my area. I did a fair amount of research and this company is the one to use for your heating and cooling needs. I highly recommend Cool Heat Mechanical for your HVAC requirements."

"Juan responded quickly on a Sunday afternoon. He was very knowledgeable and fixed the broken part. Fortunately, Juan had the part in his truck and was able to get my furnace working again. The service was impeccable! However, the weekend rates are expensive the service cost me $699 for installation of a $70 part. The 2-hour service call was $500 ($249 per hour)."

"HARP sent a rep to the house, he did the evaluation for sizing, which was in line with the sizing tools I used. The solution he offered was just about what I had picked out, and I went with his recommendation. The install went fine. They did have to be reminded to retape some ducts, but we're happy to take care of it."

"Prompt during sales call and install. Low pressure sales that made me feel very confortable that an expert was giving me the estimate, and not just a sales person with limited knowledge of heating systems.Very competetive price and products. They did a very neat job and I love the new boiler. I would not hesitate to hire them if you need a boiler. In fact I have already told a neighbor who will be replacing a boiler soon."

Install Boiler FAQs, 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.

Common problems include leaks, low pressure, and inefficient heating. Regular maintenance prevents many issues.

The average lifespan of a boiler is typically between 15 and 20 years, though some may last for as little as 10 years while others can reach 30. A boiler's longevity is influenced by several factors, including the quality of the unit, proper installation, and consistent professional maintenance.

The material also plays a significant role. Older boilers made from durable cast iron can last for over 20 years, with some functioning for up to 50 years. However, it's important to consider their lower efficiency, which can lead to higher utility bills. Modern boilers, often made from steel alloys, are designed to withstand high pressure and temperatures and have an average lifespan of about 20 years.

To maximize your boiler's lifespan, ensure it is installed correctly, have it professionally maintained each year, and address any necessary repairs immediately.

DIY is not recommended due to safety risks and technical expertise required. Hire licensed professionals.

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.
