Get matched with top furnace / forced air heating system install or replace pros in Highland Park, 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"

"Nathan was our technician and he was great. He did a thourough job while being sure to explain what he was doing and why he was doing it so that I would be able to better care for the system in between services. He arrived exactly when he was supposed to and was done in a very reasonable amount of time."

"The best heating/ cooling company I've used. My furnace problem was quickly & accurately diagnosed & repaired. The repairman even took the time to show me the 2 possible problems with my furnace. A little pricier than other companies but well worth it."

"I purchased a new furnace and air conditioner from All Temp this past summer. They exceeded my expectations. Their quote was very competitive and we liked the Bryant equipment. The job was scheduled within a couple of days. Danny and Cody were prompt and courteous, wore appropriate PPE and left our furnace room spotless when finished. Great Job All Temp and Thank You!"

"HVAC 34 years old - furnace died in January (very cold spell) - needed emergency repair/replacement - G&R came out on emergency - checked furnace (unrepairable) - got quote - they replaced furnace and air conditioner (air conditioner at my request due to cost of freon charging) - they did all within 4 hours from my initial call - great work."

"On a Cold and Snowy 2nd day of Spring 2020, my heating system went out and got really cold in the house. Called Four Seasons to come out for an immediate repair. Four Seasons was able to come out within 2 hours. Technician was very knowledgeable and fixed the the problem right away and my furnace was up and running before the freezing night came. Thanks, Four Seasons!"

"Carlos called me the next morning, and sent 2 technicians over. At several points during their stay, they were video call with Carlos discussing the situation. They found a solution and explained to me carefully what they were doing, what the next step is if this step would prove inefficient. Their price was reasonable. Carlos called me several days later to check on the system, and gave me additional advice. I would hire them again."

"Very well. The technician seemed well trained. He went through all vents and registers meticulously. Cleaned the furnace base unit thoroughly. Showed all the filters which needed to be cleaned, dried and re-installed."

"i had new furnace put in by them, there was a small gas leak from the shut off valve in the furnace, even though it was 3 weeks after one year warranty, they were very prompt in replacing the part, and did not charge for the part and service, i find this quality rare now a days."
