FOR NEARLY 80 YEARS, WE KEEP CHICAGO IN ITS COMFORT ZONE.

The year was 1938. It was the waning years of the Great Depression. New York defeated the Chicago Cubs in the World Series. Franklin Roosevelt was our president. And a young man, Walter Mehrholz, scraped together all his money and opened a business servicing and repairing boilers and heating units, becoming one of the area's first Bryant dealerships, where he had previously worked since 1927. Walter built his business with his hands, a handshake and a promise, and his small company grew and grew. The rest is history.

And thanks to my grandfather, Walter, All Temp Heating & Air Conditioning has become the first choice for tens of thousands of families throughout the Chicago and suburban areas. All Temp remains a family owned and operated company, selling quality furnaces, air conditioning, boilers, air purifiers, humidifiers, ventilation, water heaters... and provides expert equipment installation, tune-up and repair services. Our courteous, fast and friendly staff is here to service all of your needs. We are one of Bryant's highest-rated dealers in the nation. We look forward to being of service to you. SINCERELY, ROBBIE MEHRHOLZ.

My 25 year old air conditioning unit suddenly stopped cooling. Oh, boy, I thought. This is going to cost me $$$$. Marvin came to check the Heating & AC system, which meant getting up on the roof. I was very pleasantly surprised to be told that the problem was a failed capacitor. Capacitor was replaced along with a complete system check and servicing for a couple of hundred bucks. Hey, folks. This a a good honest and competent company. When you find a good company that you can trust, stick with them. And ask for Marvin. The best!

Highly recommend All Temp! We had Erwin come out to service our Furnace and were notified that a few pieces needed to be replaced. The entire process from end to end was very straightforward, efficient and very reasonably priced. Erwin was very professional and walked through the entire process and answered any questions we had. Would definitely recommend Erwin and All Temp to all!

This is my 2nd time having my HVAC system maintained by All Temp. They were here in 2014. I've had OUTSTANDING service both times. Scheduling is easy and the work is efficient. I also appreciate the return customer discount

I really appreciate how awesome Kyle's service was today. He answered ALL of my questions with patience and pragmatism. He offered advice to help me save money in the short term while planning for the future.

Thanks for giving me the confidence I need to enter into the home stretch of another Chicago winter!!

Brian Edminston from All Temp performed an annual clean and check on my furnace. Quick, friendly, arrived ahead of scheduled time (which was great) and offered great advice. All Temp has also helped me in the past when my furnace went down during a -20F day and they've always gone a little extra.

The entire process of getting our new air condition, furnace and water heater was exceptional. The knowledge, expertise, product and installation were TOP NOTCH! John and Cody were great guys. They worked hard to get our project done in two days instead of two and a half because there was snow in the forecast for the third day. We really appreciated how genuine John was. He truly loves his job and it shows! He was honest and he wanted to make sure we got exactly what we wanted. I would highly recommend All Temp and ask for John and Cody

Our furnace went out during one of the coldest winter weekends. We tried several different heating companies, before finding All Temp. The other folks had tried telling us we needed to spend $1,000+ in repairs and would need to wait up to a week to ship in parts. Ed from All Temp came out and quickly diagnosed the issue, found the part locally, and got our heat running again asap. Rich from the office was also very helpful and friendly throughout the process and made sure we knew what was going on at every stage. The repairs ended up costing a fraction of the cost and we have heat now. I totally trust these guys, they seem 10x more knowledgeable and professional than others we've tried, and did not try to take advantage at all. If you're not sure which heating company to go with, call them.

Found them on google and called this morning when our furnace stopped working on the coldest day in forever. Received prompt service on the phone along with a walk
Through to trouble shoot things first. When that didn't work they had a technician come out today. Jamie was very informative, figured out what was wrong straight away and told us how to prevent the problem in future. Heat is restored thank goodness. Now just waiting for the house to warm up again. Prices for an urgent service call were very reasonable. Will definitely use All Temp heating and air conditioning in the future.

This review covers service availability and listening to your customer.

I was out of town when my son came home from work to find the heat at 62 degrees and a service message on the thermostat. Morning temperatures we're predicted to be 14 degrees, so we couldn't wait for service. After calling our usual guys and finding them closed and without an emergency number like they used to have, and making several calls, I called All Temp. The answering service was pleasant and forwarded our call so that All Temp called me back within 15 minutes. She took down all our information, told us how soon the tech could come out, as well as just listening to our story.

The tech was out even sooner than promised and got the furnace running correctly. The next day, I got a call from All Temp making sure things were okay. I appreciated this, as he also knew the details as well.

I do on-call in my job and know how it is, so I appreciate even more how quickly they responded. Thanks!

Customer Testimonials

We have used All Temp for over 15 years. They have been there for new ac and heating units, repairs and service calls. Most recently I had a hot water heater leaking water on a Friday night. Ed came to the rescue first thing Sat morning. As always I received quality service and a smile. Ed is THE BEST!! All Temp will always be my first call.


I have used All Temp in the past few years to maintain both my furnace and air conditioner. In January 2018 I made the decision to replace both my 18 year old units. Mike visited my home and made the best recommendations of what units to purchase. He knew his product well and was patient in answering various questions. I felt very confident that i was getting the best product at a great price. Both units were installed in less than a week. Jaime and Ernesto were very efficient and professional when installing both units. They did an excellent thorough job and left my house more tidy than when they started.

The icing on the cake was when I reached out to Mike to gather some information to fill out rebate applications, he volunteered to fill out the applications for me! What a timesaver! From start to the finish i had an amazing experience with every All Temp employee. I will be a lifetime customer! I highly recommended All Temp for any heating and cooling needs!


All Temp is the best heating and air conditioner business out there today. Their response time is incredible and they are always so curteous. Our old heating unit broke down in the middle of winter and we had a new one, up and running by days end. Robbie and his entire crew are honest and wonderful. It is so nice to use a company whose employees have been there for years, and some from the beginning. Honestly, we have never had a problem with All Temp.


Amazingly fast and WONDERFUL service! We had no heat and within two hours of calling it was like they waved a magic wand and fixed it temporarily! The next day they came and replaced all the parts for a permanent fix! Parts were supposed to take days to get but with All Temp they were delivered and repaired in hours! Friendly staff, honest, caring and helpful! He even rang my doorbell after to remind me to close my garage door for safety! They go above and beyond every time! The best and fastest service!


I moved into the house in my community some 17 years ago and was introduced to All Temp early on, I was told that "one of the guys" lived in the community also, so I thought there might be some benefit in keeping my business "local". As a 1st time homeowner in the area I had no idea on the many things that need to be attended to and having no experience I was desperate to find good service companies to help me get through my homeowner issues.

I recently flew back from Fl and as I was landing after hearing about the brutal cold Chicago had experienced a quick thought popped into my head about would my home be warm when I got there? I also wasn't worried because if it wasn't I knew who I'd call and knew I'd get GREAT service as I always have in the past!! Fortunately I arrived home and the recent prior regular annual maintenance we received from All Temp held it's "promise"and my house was warm :) .

As a now "experienced" home owner I'm grateful for all the years of service, regular or above and beyond that All Temp has provide my family and home.

Thanks guys for always being there for me and making my "issues" your top priority.


I've used ALL TEMP for a number of years. I was without heat during this recent cold snap and called All Temp right away. The office staff was very helpful and a technician came out right away and fixed my furnace. The technicians were very courteous and efficient. I would recommend ALL TEMP to anyone with heating or air conditioning problems. This is a great company.


I found the salesperson I dealt with at All Temp to be straightforward and honest. I had been shopping furnaces and thought that replacing the furnace I had to replace the compressor as well. When talking to the All Temp guy he told me not necessary and refused to sell me one and take my money. Not being in HVAC how would I know? I have found their prices to be more that fair and the service is excellent.


All Temp has help with my real estate clients as well as my own personal home. They're easy to work with and make sure my HVAC is running top notch. I would definitively keep recommending them to everyone. Keep up the great work.


Chicago winters are NO JOKE. I had a few companies on my list to call with some flat-out refusing service. All Temp was the one company that stepped up to the plate and made it happen. I called and within minutes, received a call back from a technician letting me know he's on his way. I did need my equipment replaced, but the team I worked with were so professional and kind throughout the whole process, I would definitely use them again. Just Incredible, I highly recommend them for any of your services. When I arrived my home was 44 degrees, tonight it is a toasty 72 degrees


I absolutely 100% know this company will fix any issues I have. I love having a company I can trust. Their cost is reasonable and their employees are very nice and knowledgeable.


I have to say I had a great experience with All Temp when they came out for no heat. Very fair prices and very professional. My heat was working great after they did the repair. I would definitely recommend these guys!!
