Best boiler installation pros near Saint Charles, IL

"Home Comfort Systems did a fantastic job with the replacement of my furnace (and my A/C five years ago). Steve is a highly reputable person and explains things easily for people not in the Heating & A/C industry. He is very straight-forward with his quote and doesn't try to pressure or scare you into purchasing something you do not need. Their 10-year labor warranty is also very impressive, and they stand behind their work. A couple of weeks prior, they were able to take a look at my old furnace right away despite having tons of calls due to the first cold snap of the year. The furnace install only took about three hours and was smooth as can be. The installer took great care in making sure floors were protected when hauling equipment in and out of the house. He also made sure to repair some ductwork that extended off the furnace. My suggestion is to make sure you call Home Comfort Systems if you need service or replacement of your furnace and/or air conditioning."

"Excellent installation of new furnace and air conditioner. Explained the problem and recommendations to resolve it. Both technicians David and Jimmy, were professional and knowledgeable abd worked efficiently. Although, expensive project quality was worth it."

"Tim came out for an estimate. He was professional and knowledgeable. Not pushy at all. On the day of installation, he and his team were respectful, efficient, and left our home clean. He thoroughly explained everything, and programmed the thermostat for us. We will use them for all future maintenance. Highly recommend."

"Everything went fine , issue with they sent the wrong furnace but came back the next day and fixed it. They did excellent job in the installation."

"The technician that serviced my boiler was Aiman. He was very professional, thorough and informative."
