"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."

"We decided to replace an outdated AC unit and furnace with a brand new heat pump and furnace. After speaking with a Four Seasons sales rep, we knew they were the best choice to go with due to their thorough assessment, knowledge of products, availability of service and overall transparency. And perhaps most importantly, they were not pushy and respect our decisions on what system we felt was best for our home. As with any expenditure of this nature, there will be some ironing out of details and inevitable bumps to get everything completed, but the overall experience amounted to an energy-efficient HVAC system that was installed with care and expediency. Their service technicians are also friendly, thorough, knowledgeable, and available at a moment's notice. We are so glad that we went with Four Seasons."

"Best in the business. Art did quality work at a fair price over several visits for me. I cannot say enough about the honesty and professionalism he exhibited. Discovery is the best HVAV firm I have ever used. This matters. Being a professional woman means nothing to some folks. Some firms see a woman and take advantage. That did not happen here. I am a 30 year homeowner. Like you, I am just looking for an honorable service partner to handle the systems in my home. It is a puzzle until you find a great partner to help you run your systems. HVAC systems can be a matter of life and death. I had Art out after a flooded basement to check the furnace. Fair price, good advice on that event. Later, I had my furnace motor go out. Art came and replaced it in a very professional manner and at a very fair price. Hey, we can all go on line and figure out what a part costs. Discovery and Art were fair and gave me tremendous peace of mind. My heat is on right now and it is perfect. I got a price for my cooling that I will replace in the spring with Discovery. Why? They are fair, professional, knowledgeable, and have shown me a track record excellence. For women who have been ripped off, I would especially recommend this service. Ask for Art. I heartily recommend Art and Discovery for your HVAC needs."
