"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"

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

"Very impressed with their heating and air conditioning maintenance. They explained everything clearly, worked efficiently, and left no mess behind. Our home feels fresher after the air duct cleaning. Definitely a trustworthy team you can rely on."

"The air conditioner is working fine."

"We had a great experience with Four Seasons Heating & Air Conditioning during our recent replacement of our furnace and AC unit. They were very professional and completed the job on time and answered all of my questions. Would recommend them for our Heating, Air Conditioning, Plumbing and Electrical needs."

"When we purchased this house 20 years ago, we hired a different company to replace the furnace and air conditioner. There was very little flow so they replaced several of our runs also. After all that work and expense, we were forced to run two window a/c units along with our central air. Yet our house still would not cool! We were extremely frustrated. When we hired One Hour Heating and Air Conditioning, Phil was sure he could help us. And he did. We cannot believe how wonderful our house cools. Phil was very accommodating, as we had to split the installment dates for the furnace and air conditioner. He always returned our calls, answered all our concerns, was timely, efficient and professional, as was his staff. His service and equipment exceeded our expectations and we give One Hour Heating and A/C our highest recommendation."

"We had five companies come out and look at our house and give us quotes for installing a Spacepak or Unico system in our house. Phoenix gave us the lowest quote (16k less than the highest quote!) and also had the best customer service. Everything was explained to us before, during, and after the installation. The owners seem to have a genuine passion for HVAC, which I wouldn't necessarily expect! Anthony was great with figuring out ways to get air to all the rooms in our 110 year old house with many quirks. Glad to have found this company."

"I used this company before and decided to give them another try. My furnace was blowing cold air. The tech was very nice and made sure I understood the work that was being done. My heat is back on and it didn’t break my pockets!!!! YEEEES!"

"I had the best experience. It was a super hot day and my air conditioner stopped working (it had given me problems in the past and i knew it was time for a new one). Called Keith Lascos heating and cooling; told them the situation and they said they would be out by my house around 5pm. Not only did they show up on time but they completed the installation the very same night. The price was fair and they answered all my questions and ever since I have had no problems with my AC. It was probably the best experience I've ever had with a HVAC company."
