"From first contact to finished installation our experience with this company was perfect, outstanding. We purchased a home and needed a new HVAC system. A new HVAC system sounds like a hassle, but these folks made it easy. Trinity, Jeff, Erik, Colton, and Austin are so professional and just a pleasure to have in your home, they go out of their way to be helpful. If every company was like this one the world would be a better place. Highly recommend. Look no further, use these guys!"

"Pretty good overall, though there was delay in ordering parts and after installation, they had to return the next day to adjust cables in one of the furnaces which had gone out. All works fine now. The bill came in a bit under the estimate and there was no charge for coming out to make the adjustment. (Their initial call out to assess the situation was reasonable, ~$65 w/ tax.)"

"Purchase and installation of heat pump went very well. David came the very next morning after my call for help. He gave me the estimate on the best pump suitable for my needs plus all the equipment and labor to complete the job. The day of installation everyone arrived early. Each person had their specific part and each went right to work. The whole system was completed the same day. Everything was cleaned up and the old unit hauled away. Nick came to do the inspection after a week to see if all was running well. All were so friendly and professional. They did a great job. I have had a maintenance contract with Quality Air for several years and all the guys who come to my home have been friendly and professional."

"Mike's quoted 3 systems; the multi-zone Mitsubishi hyper-heat system was about twice the cost of the Trane single-zone std. heatpump. The quote from a 2nd HVAC installer for a standard Carrier single-zone heatpump system was only $1000 less than Mike's Mitsubishi system. I wasn't originally considering the Mitsubishi because of the cost but the Carrier-system quote changed my mind. It took two days to complete. The installers were efficient, professional and amiable. They did a good job and took the time they needed to install the equipment correctly and make it look good. The condensor unit was delivered to Mike's with a dent; they gave me the option of a price break or getting another unit shipped next-day. The Mitsubishi system they installed operates much differently from the 13 year old standard-heatpump-system it replaces; before they left, the technician took the time to explain what to expect regarding the system's operation and encouraged me to contact Mike's if I had any questions or concerns."

"They were able to come in, configured, and installed properly the water heater and the furnace. They contacted the company and registered me on the agreement. It was a lot better than I anticipated. I made them the contractor of my choice. I was lucky to find them."

Install Boiler questions, answered by experts

The cost to install a steam boiler varies depending on the type, fuel used, and your house size. The average cost to install a boiler is $5,900. You could spend $2,000 for a basic electrical steam boiler or up to $9,000 for a high-efficiency oil-burning steam boiler. Boiler installation is a job that’s best left for professionals to complete, and, in some states, only licensed installers can legally complete the job.

No, there isn’t always water in radiators. In a one-pipe system, water is constantly circulating from the boiler to the radiators and back. In a two-pipe system, water travels through two separate channels: one that goes to your radiators and one that returns back to the boiler so it can heat up again.

The absence of heating or hot water, unusual noises like banging or gurgling, and visible water leakage are key signs. Abnormal boiler pressure, flame irregularities (for gas boilers), or pilot light issues may also signal trouble. Frequent cycling, soot or staining, and unusual odors, particularly gas-like smells, should not be ignored. Modern boilers often display error codes or lockout mode upon detecting issues. Uneven heating across radiators and rising energy bills without increased usage can further point to problems. Prompt attention to these signs is essential to prevent further damage and ensure safety.

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.

Some high-quality steam boilers come with 10-year warranties, but a well-installed, properly maintained model can last at least 20 to 25 years. Learning how to clean a boiler, getting an annual professional service, and keeping up with maintenance and repairs on your heating system are all important for getting the most out of your model.
