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

"The experience was great. I was referred by a friend. I called and set an appointment. The technician was prompt, and very professional. He checked the furnace and described the problem. A major component had failed. He said I had a choice of either repairing the furnace, or replacement. The repair was not something I was interested in, so I chose to replace it. The replacement was done in a timely, and professional manner. I highly recommend All Temp for their professionalism, and making my furnace replacement a very positive experience."

"Outstanding service from beginning to end. The team arrived right on schedule, worked efficiently, and left everything spotless. Our heating system runs better, and the air feels much cleaner."

"Cahill installed my new furnaces in a professional manner and the units work very well. The annual service is thorough and complete. I am confident that the units are well maintained and not just given a cursory service. Installation of the ducts was done quickly and professionally and their advice helped me make the right decisions. They showed up to perform the work at the agreed time and completed the work efficiently. I didn't have to allocate a block of hours during which they might show up -- as with most service companies. I'm very pleased with this company."

"On Friday, Oct. 2, 2020, three young men came to install my new electric heating/cooling system. (Lennox Air Handler CBA25UH-036 and Lennox 13ACXN-036) They called before they came and came on time, as well. They were friendly and polite and were very respectful of my property and put down floor coverings over my carpeting. They all wore shoe coverings and masks (due to Covid-19). One man worked out on my deck installing the air conditioner, and mainly one other young man worked on installing the furnace with the assistance of one of the men at times. It seemed like one of the three men was in training. Due to the fact that the new furnace was rather large for the small closet area where it needed to fit in to, the young man who was mainly installing the furnace was able to overcome the challenges that he faced with the help of one of the other men and he was able to fit it in. Thankfully they did not need to drill any extra holes into the ceiling or walls to install the furnace and I was very thankful for that! They were there for at least eight hours. I was hoping that I would finally have heat that day, but I was told that the heat exchange part was cracked and they would have to send someone else out to install the new part. Before leaving, they cleaned up everything and did not leave anything at all behind for me to deal with. They also ran the air conditioner for quite some time to make sure that it was working properly, which I was thankful for because it's very important for technicians to make sure that each job is done properly before moving on to the next one. Since the job was not yet completed I only paid a little over half of the price that was due to be paid and would pay the remaining amount when the job was completely done. A woman from Four Seasons Customer Service called me later that day letting me know that someone could come that night between 9p.m. and midnight, but I chose to wait until the next day for someone to come out to install the part. She was very pleasant and helpful. On Saturday, October 3, 2020, technician, Santino M. called to let me know that he would arrive at my home soon to install the part. He was also very respectful of my home and wore shoe coverings (as well as a mask). He was very friendly, kind, and caring and did an excellent job of installing the new part. He carefully read the instructions and checked and rechecked all the wiring to make sure that everything was installed properly. It was a blessing to finally have heat! He made sure that my furnace was working well for me before he left and he also gave me helpful tips, providing me with some information that I needed to make sure that my system would work well for me for many years to come. He provided excellent customer service to me, as well, going above and beyond normal good customer service by taking a few extra minutes and leading me step by step in applying for my Lennox warranty online before he left. I would definitely give Santino M. a five plus star rating on his installation and for his kindness and excellent customer service! Thank you so much, Santino! As a whole I was very satisfied with the service that I received from Four Seasons Heating And Air Conditioning in Chicago. Although I was very concerned at first after reading some of the reviews regarding what some customers experienced dealing with other Four Seasons Heating And Air Conditioning companies in other areas, so far I have found this Chicago based company to be very caring about their customers and they seem to do their very best to provide fair and affordable prices for their customers and very good customer service. (Thank you so much, Keith W.)! I did sign up for the extended 12 year warranty, so if I do have any issues in the future with this company I will update this review to express any concerns that I may have."

"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."

"Phoenix HVAC is the only heating & cooling company I will ever use! They are thorough, professional and explain all options available. I never felt pressured to make a decision to repair or replace, and the final installation is impeccable... the job site was cleaned to a state better than it was before they started! They answered all of my questions and were extremely flexible when scheduling the work. Having the team @ Phoenix perform this work gave me peace of mind on the eve of sub-zero temperatures! Thank you Bob and the rest of the Phoenix team!"

"From the moment I picked up the phone and talked to Nora and Tracy to discuss their services, through Caesar and Manny leaving our home after giving our ducts and vents a much needed cleaning, Mr. Duct was an absolute to work with!  After having our wood floors refinished, it was important to have our vents thoroughly cleaned from the saw dust.  Not to mention, the HVAC system is 12 years old and could've used a cleaning anyway.  Everyone I spoke to or met with in person were polite, courteous, punctual and professional!  They came to me highly recommended and left with their reputation unblemished.
