Get matched with top boiler installation pros in Chicago, IL

"They did good work. I have a boiler and their boiler man was excellent. I will call them in the fall again. I did not compare prices because I wanted this particular company. He was very professional. I had a problem with the wording of the coupon, it didn't mean what I thought it did. I thought a furnace cleaning would be considered a service call. A service call is for a repair."

"Pros all the way. Your experience starts with Adam in the office who handles the front end to the installers. From beginning to end the experience is painless & trouble free. It took a few hours & done. Haul away & clean up. Thanks to all Pam in Cresthill il"

"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."

"Within 5 minutes after Roy walked in, I knew I was speaking with an expert. He talked me out of wasting money on what I wanted (getting rid of boiler and replying on furnace) telling me about how everyone in the city during -40 degree nights was will freeze and if I keep the boiler I'll be comfy. He also talked me out of choosing a heat pump, saying in Chicago it will cause problems in the dead of winter and then I'll be out of luck. Initial estimate was only to replace the 60 year oil leaky boiler and 40 year old loud AC and furnace. Came in, did the work quickly, and when we were doing final inspection he pointed out where my last remaining original furnace was having problems. Gave me a great price to just get the the last furnace and AC done (AC was 40 years old). I know they won't be the cheapest but if you want someone you can trust who will guide you with his 30 years of experience and teach you the finer details of heating and cooling while delivering quality work, go with Porterhouse. I won't trust anyone else."

"Technician came after hours to give us a 2nd opinion on our old boiler. I was told by another company that the draft wasn’t working properly and had the potential to leak CO2. Technician, Craig, was very thorough checked everything and taught us a lot about how it works. It was expensive because it was after hours but that’s expected. I definitely will be using them again."

"Jon showed up at 7:00 am on the dot, exactly 2 days after his initial visit to install my new 2 stage carrier furnace. The price included the materials to raise the unit, the necessary metal work for the ducts, and a new thermostat. The people who installed the first thermostat installed an incorrect one not suited for a 2 stage furnace. He removed and disposed of the old furnace and installed the new one without incident. Jon took the time to walk me through the use of a programmable thermostat and where to place the filters. My basement was left immaculate."

"They came on time the appointment was scheduled, found out exactly what the problem was and went right to work to repair my boiler. They knew exactly what to do without a lot of guess work. I was very impressed with their professionalism, honest and frank analysis of what the problem was. I will definitely recommend them to close family, friends and neighbors."

"Tim came out promptly, made a diagnosis and explained it so that I could understand, and arranged for a replacement the following day. David and David arrived the following day on time and, unfortunately there was 3 feet of snow blocking their path to getting my boiler out and the heavy cast iron boiler in. They worked together to shovel a path, and then worked continuously through the day until the job was done. David did a great job of explaining the workings of the boiler and left the place mess-free."

"The boiler had needed some replacement pipes as well as the solution to the slight smell of gas when near the boiler itself. Prior to calling for service for these issues, I had removed the majority of the damaged piping and purchased all new of what I was able to remove. I couldn't remove the bushing that attaches directly to the boiler or the nipple that attached to that bushing to save my life. On the night prior to the day of my appointment, there was a snow storm and time moved ahead. I had forgotten to move my clocks ahead that resulted in my arriving about 20 minutes late. The repairman was kind enough to not only wait for my arrival, but to shovel part of the snow from my walkway that leads to the basement. This guy is just great. He removed the fused together bushing and nipple in no time flat. It was amazing for me to watch. I had to pick up a couple more pieces of pipe for my job to be completed and we scheduled to continue after I did so. Luckily, The pipe I needed was in stock and he was able to return the very next day, he removed my bushing and nipple, installed ALL of my pipes, and provided and replaced my leaking gas line. MY BUILDING NOW HAS HEAT AND I COULDN'T BE HAPPIER!!! Now I have to have the other parts of the building repaired that were damaged from when the boiler had stopped working and a pipe had burst. You won't be disappointed if you hire Discovery Heating and Cooling. If I have another related job in the future, I will definitely call Discovery. Thanks again Discovery."
