Get matched with top furnace / forced air heating system install or replace pros in Lake Forest, IL

"We recently replaced our Heating & Cooling system with a energy efficient furnace & air-conditioning unit. We knew what we wanted, so I received bids from 4 different suppliers, receiving bids for a apples to apples comparison. All-Temp was by far the best pricing. Our installation process went flawlessly & the installers answered any question that I had. They came back out to our home per my request on a couple more occasions, to adjust the amount of time the 2 stage system ran. Everyone that we have dealt with has been extremely professional, courteous & knowledgeable. We just received a clean & check of our system & Jen our technician met each of those attributes. I would highly recommend All-Temp for any of your heating or cooling needs. Herb Pitzman Huntley, IL"

"All Temp Heating & Air Conditioning crew were timely, professional, and did not try to up sale me more expensive furnace. Work was completed quickly, they cleaned up afterwards, and the new furnace is working perfectly."

"Dwayne from G & R Heating & Air did a very thorough job checking our AC system. He verified everything was in good working order. Dwayne was professional, courteous and friendly. I ended up purchasing the service contract."

"They've put in a new furnace, water heater, AC, etc. They are very reliable, but not inexpensive. Everything they do is quality and they only work with quality people. I had a problem with the air compressor on our AC right after the warranty had expired. Cahill said that they work with that company all the time and that part shouldn't have gone out that quick. They said they would talk to the company and see that it is made right, and they did."

"We decided to replace an outdated AC unit and furnace with a brand new heat pump and furnace.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."

"I hired them to install new combined water heater/ boiler, install new water filtration system and service the ac units.Great service and knowledgeable of what theyâ re doing. Definitely will hire them again."

"Rick was very helpful with selecting my new central air and furnace system. I am still thrilled with the result."

"Bought Amana (Single Stage) HVAC System. Our old American Standard HVAC broke. They came in 2 weeks before and replaced the Gas Valve for $600 and 2 weeks later that broke too because of the electric board. They convinced us that instead of spending more money on parts that may also break later it's better to buy a new HVAC system. They recommended Amana dual stage - Variable system but next day they called that it was a mistake to recommend that because it doesn't exist in 15" size, so now they recommended Single stage and lower the price by $500. Not only that, but they helped us and went out of way to accommodate us with price. Likewise, they fixed it during Thanksgiving weekend."

"Friendly reliable owners and staff. Work was completed when scheduled and professionally. New AC was installed with furnace. Since it was cold out, I was assured They will check outside condenser unit in the spring. Comforting to work with a good company."

"Maintenance and checkup on my furnace. Needed someome fast as I am about to rent out the house. Easy to schedule and price was fair. Would use again."
