"Excellent service all around. Called, answered promptly, got a fixed-price quote for cleaning our 3000 sq ft two-zone heated home built in 1959 and likely not cleaned since it was built. Competitors were much more vague about services and pricing and generally were "we can come out and charge you depending on the setup...". They explained clearly what they were going to do, how long it would take, and what results we could expect. Called ahead to check that we were home and suggested clearance of area around vents to ensure no breakage. Arrived promptly and on schedule. Put on booties before entering home. Were clear about work to be done, rough timing, and access needed. Set up large vacuum unit in backyard and large hoses through basement window, along with several agitator lines to clean each vent. Removed all vents (supply and return, about 30), cleaned them all, replaced them all correctly. Cut two access holes in ducts where necessary due to our ducting setup and patched. Vacuumed around all work areas. Cleaned out vents, which they informed us had gravel and tile (!) in them from a previous renovation. Promised four hours, took 3.5. Was noisy but not unreasonable given work performed. Outstanding and professional service. $500 total for a complex job, billed as promised. Would recommend highly."

"Had a major problem with my rug. The vacuum cleaner belt broke and melted. I had black spots all over my rug. He came over on a Saturday spent a lot of time and did a great job."

"In May of 2021, CR Mechanical replaced our HVAC equipment (furnace and AC), and installed a new air scrubber and an ecobee thermostat. We were very satisfied with their work (exceeded expectations), and Craig is an excellent installer (that was most important to us). The ecobee was defective out of the box, and he reinstalled our old thermostat and was back the next day (as promised) to install a replacement ecobee. Everything works great."

"I called them for central A/C repair and furnace servicing, and they exceeded my expectations. The team quickly diagnosed the issues and fixed everything without delay. Their professionalism and attention to detail really stood out. Highly recommended for any HVAC needs."

"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"

"I had the most positive experience working with Bob and Anthony on a full Furnace/AC installation. Both systems were approaching 15 yrs old needing repairs that would not have made sense to continue putting money into. Bob came onsite for a free consultation and very clearly communicated detail on my options, even making recommendations for further cost-saving improvements. They fit me in right away and worked diligently with the installation. I couldn't be happier with the end result...should have called these guys months ago!"

"Excellent service from start to finish. The technician handled our thermostat installation and central A/C repair quickly and professionally. Everything is working perfectly now and the whole process was explained clearly. Very reliable team and highly recommended."

"Very responsive and offered options for financing. The Legendary Service Team has a thorough understanding of regulations and offers environmentally friendly suggestions for your HVAC needs. They did a furnace/AC replacement in my home. Their scehduling system texts you when they are in route to your home. The install went seamlessly. They kept all work areas covered and clean. I will use them for all future maintenance needs."

"Went okay. Based on some of my past tuneups, I felt like the tech could have done a little more. For example, tech had no vacuum to clean the bottom of inside the furnace. I am not sure he did any cleaning of the INSIDE of my central air unit either, but he did a great job using the hose to clean the side vents, etc., with the garden hose. Also not sure if he ever used that device with the hoses and gauge usually used to check pressure or is it Freon? For $89.95 for each (central air and furnace), I expect a super thorough job. I can’t get around these tuneups or I will void my warranty. I want to feel uber confident I am getting my moneys worth. Tech was super nice and very professional!"

"Phil was everything you could ask for as a furnace repair person, knowledgeable, courteous, answered all of my questions without reserve and went out of way to check all systems in the furnace beside the repair that was needed, parts were a little pricey, but fair!"
