This was my first time using All Temp but will not be my last. I called and left a message and received a prompt professional response in less than 30 minutes. I explained I had just moved into a new home and was hoping someone could come check my HVAC and ensure all was working properly. I was scheduled for a convenient for me time. On the day of the apt the team showed up 30 minutes early which was awesome and wore masks and booties. The two man team did an awesome job and gave me a lot of little helpful tips. The price was very reasonable and I will definitely be using this company for all my HVAC needs!!!

I can't say enough nice things about AllTemp! We had a +20yr inefficient noisy old system that was jammed into its space that didn't even heat the basement! Start to finish, everything was top notch - professionally, cleanly, orderly, and meticulously done.

Plus, Tony is so good he was able to reroute the duct through the ceiling instead of cutting into the original 1920s living room wood floor.

Annnd, Mike even sent back his best electrician to address an unrelated but might be related electrical issue that arose as work was being done (two lights stopped turning on) - all fixed!

My house is as cool as a frozen cucumber after All Temp came by for an inspection. They diagnosed the problem lickety split and the price was so reasonable I had money left over for a banana split. Turns out I'm a bad operator, they set me straight, helped me to remove the training wheels and now I'm cruising down the street on my own like an extra luxe cold front breezing into your zone, chillin and grilliin out the remainder of the summer with Ecco-centric efficiency. Thanks All Temp, you can come back anytime to check out my ducts.

Are A/C unit broke down and a family friend recommended All Temp. They came out and reviewed my setup. They recommended a A/C unit and came out week later and installed it. Their work was clean and fast and they even had to expand my attic entrance since it was smaller than unit up there. Everything went well and we have a great unit and we were very pleased with the results. We would recommend them to anyone.

They had to cancel a scheduled weekday appointment due to an extremely cold day in October and more pressing requests. (Winter in Chicago has started early :(. ). They kindly rescheduled me for a weekend. Jeff came out and was wonderful. He was professional and educated me on the basics of my furnace. I highly recommend this local company. Thank you.

My HVAC system was a comedy of Errors. But All Temp sorted that out professionally and quickly. John, Cody and Charlie were great. I basically had two old furnaces that were configured incorrectly and held together with bubble gum. I also had an air conditioner on a roof that was not flat. No problem John and his crew removed the air conditioner from the roof and relocated it to the ground. They also installed my furnaces and vented them correctly . What a relief!
All Temp is solid and reliable. Thanks again gentlemen.

Customer Testimonials

I have been with All Temp for 4 years now. They have installed a new furnace and air system. These guys are not only very smart and honest, but actually take the time to explain the things that a homeowner likes to know--in simple terms. Their price was unbeatable by a lot. We now use them for annual service to keep things humming. I highly recommend these people. You will be a customer for life.


The heat went out in my father-in-law's home where he lives with his wife and her three children. Temperature was 4 degrees on that Saturday night. The wife called All-Temp and did not tell them that the owner is one of my childhood buddies. All-Temp immediately dispatched a tech on a Saturday night who diagnosed the problem as a blown motor. The unit could not be fixed that night. In order to get the replacement motor, All-Temp had to pay their warehouse to open on a Sunday morning.

They got the motor and fixed the heat all in under 12 hours during the coldest day and night of the winter. All-Temp's owner took the call from my frazzled mother-in-law and calmed her down. Again, on a Saturday night. The owner spoke to the customer with empathy as if he were a doctor soothing an sick patient. Did not matter that I knew the owner--it never came up and it didn't matter. This is kind of service that every business should offer but, regrettably, rarely does. News of this excellent service has and will spread like wildfire. This is the kind of professionalism which weds a client to a business for life.


Before I start this review, it's worth your knowing that the only thing I hate more than the daily maintenance of a household in the 'burbs is the un-daily stuff -- insurance claims, floods, mail delivery problems. You know, that kind of stuff. So when my heat wouldn't run in late March during a cold snap and it got down to the high forties in my house, I was not a happy camper.

I called All Temp and got an after-hours technician in my house (at 10 PM!) and working on my problem that night. The problem was my thermostat, so the technician replaced it, and soon everything was up and running.

But last week when the heat wave came in, I had no A/C, so there I was, back in angry suburban homeownerland. All Temp came out early, early on a Wednesday (7 AM, working around my work schedule, dropping my toddler off at day care, the whole morning shebang) and in less than 10 minutes figured out that a shorted wire connected to my thermostat was the problem. Although the t-stat was fine for the month before, the fact that it was new and that the last technician might have noticed the bad wiring left the company feeling responsible to me, to the tune of a $100 reimbursement of the thermostat's cost.

I still hate dealing with the unexpected, but if I can deal with it with fast service and employees who are willing to take responsibility for a problem they probably didn't even cause, that makes it all a little bit easier. I would definitely call All Temp again.
