"We have central heat, it's like a boiler, and they inspected it and they found that the hot water cut-off part, which is a significant part for operating it safely, was not in good condition. He ordered the part for us, and got it rather quickly, that same week. We like them. They have a provider there, that maintains our type of furnace, which is a Peerless. We like this man, because he knows what our furnace should be like. We've only been dealing with them for, it was last season and the one before. Our previous man had retired and was no longer available. Both times they sent somebody who clearly knows what our furnace should be like, ans when it's operating right."

"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."

"I’ve continued to hired Schavitz for all things A/C and furnace for my home due to their knowledge, honesty, and professionalism. This time met with Craig since he specializes in boiler systems and once again he exceeded my expectations with his knowledge and service. If you want complete transparency and the highest level of service then don’t hesitate to hire Schavitz. Don’t forget to ask about their membership plan.....discounts on annual services, parts, and equipment. Great deal!"

"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."

"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."
