"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."

AWE (Air, Water, Energy) did a great job. The installers arrived on schedule and worked all day to removed the old equipment and installed the new equipment.  When they were finished, everything looked great and the work area was completely cleaned up.  The air conditioner has worked great all summer and kept our house at a comfortable temperature.  I am looking forward to a similar experience with the new furnace, also.  After the system was installed, AWE sent an inspector to our house to make sure the job was completed satisfactorily (which it was) and take pictures of the equipment to make sure it was installed correctly (which it was).

FYI, we have been a customer of AWE for over twenty years because of the great service they have always provided.  This was the 2nd furnace and air conditioner we have purchased from them.  They also installed our current water heater.  The technicians are always very knowledgeable and friendly.  They always arrive when they say they will arrive, and do what they promise.  The services provided have always met or exceeding our expectations.  I would recommend AWE to everyone.

"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."

"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."

"Keith and his partner were very good. The price for the humidifier and installation was very competitive compared to others. I highly recommend them for your next HVAC repair or project."
