Did not show up for the first appointment and said they would be back the following day. Didn't show up for that appointment. I wasted a second day waiting for them. I made several calls to set up a third and they kept saying they would call me back. They never did. I decided I can't trust these people.

Our service from All-Temp Heating and Air was perfect. Our tech Marvin was timely, called ten minutes to make us aware he was on his way. Marvin inspected both air conditioners and had them up and running quickly. I would recommend Marvin to any homeowner for excellent service and great workmanship. Well done All-Temp Heating and Air! Thank you Marvin.

There is a reason I have stuck with AllTemp for over 5 years. Their service is impeccable. They put their customers first and listen to not only their concrete HVAC problem, but also the distress that loosing your heat or cooling can cause. They have been there for me to help guide me through difficult installation and insurance issues. They are so great and I have known them for so long I actually know many of them on a first name basis. Bryan is especially amazing! They have been there to help when I really needed it. I usually never write evaluations, but these guys are so great they deserve 10 stars.

My entire family has been using All Temp for all our heating and cooling needs for decades. They recently installed a new high efficiency furnace and AC unit at my home. Great job! They are always prompt, reliable, knowledgeable and always get the job done at a fair price. I highly recommend All Temp for all of your heating and air conditioning needs. Thanks to Robbie & Ricky the owners for all their help! Randy

I had a 13 year old system and had some repairs on it over the years. Finally got down to putting more money into it or replacing which made more sense. They arrived on time wearing masks and boots to protect my wood floors. I had it all replaced. Furnace, ac, electronic air filter, uv light, Bryant thermostat and a auto humidifier. I had it priced out and they gave me the best price on a Bryant system.

Two men did the entire install in one day. They hauled the old system away and cleaned up everything. Newer system is quieter both ac unit and the furnace. We are very happy with the price, system, install and overall operating experience

My experience with All services has always been good. but my reason for taking time to write a review during a very hectic time in my life is to acknowledge a job well done, and also express my gratitude to Jeff, the technician who came out to replace my thermostat earlier today 3/3/2022 not only did Jeff have a great attitude. but he went beyond the call of duty. taking extra time in explaining simple preventive measures I could implement that would help avoid expensive repairs in the future. Thank you.

Recently moved to Del Webb in Huntley and was unhappy with my furnace. I noticed an "All Temp Heating and Air Conditioning" truck in my neighborhood. After talking to my neighbors, who highly recommended this company I called and asked to talk to Rick, the manager. Rick came to my home the next day and gave me a very reasonable quote. The next day he sent 2 of his men, Mathew and Rich, to install my furnace.

Both men were on time, very kind and knowledgeable. They effectively completed my furnace, explaining everything to me. I am very happy with this business and highly recommend them to anyone. Will be having this company install new air conditioning soon. Thanks to all!

Unbelievably great service. AC went out during summer and wasn't repairable. Replacement was done next day at a great price. Technician was very polite and got the work done quickly and was very clean. Also had a humidifier installed on furnace. The unit was faulty and fan ran backwards from manufacturer and didn't work properly. Obviously no fault of technician or All temp. He showed me the problem and explained how the system worked and what the problem was. Replaced the unit and no problems since. I felt that they appreciated my business and would definitely recommend them to anyone needing furnace or AC repair.

Called All Temp Heating and Air installed on New rehabbed second-floor. New heater and air conditioner in the attic. They did a fantastic job. The employees are polite but really know their job. Everything has been working really well. I recently wanted to install new concrete under the air conditioner outside. So I had them disconnect them Off the units, I installed a new concrete, they came back on a day they said they would and we hooked everything up! Everything is working fine I will always use all temp heating and air conditioning service on my home.

I made an appointment with All Temperature to install a new heating and cooling system. They provided me with information and they were very good about keeping me in loop with the process. I was very happy at how clean and efficient they were. The installation was done perfectly and I wish that I could've done this a long time ago. I'm very thankful for the price that I got compared to other companies. I would definitely recommend this company!

When my heat went out I called All Temp for emergency service. I called them on a Saturday morning and Ed arrived at my place in the early afternoon, during the ETA window they gave me. Ed quickly diagnosed my issue as two fold. First he noted that the pilot light on my furnace was out and taught me how to relight it if that happens in the future. But my heat still wasn't kicking on so he took a look at my thermostat and determined the wiring was loose and fixed it.

He also informed me that my furnace (which was installed in the 80's) is pretty inefficient for the size of my apartment and gave me some advice if I were to replace it. I found this very helpful since I've been planning on replacing my furnace and the information he gave me was useful. Additionally, All Temp was upfront about the cost of an emergency visit before they sent anyone out so there were no surprises when it came time to pay the bill.

We had a furnace installed by All Temp 11 years ago. Unfortunately, there was an issue with the heat exchange which was detected by Marvin. Due to Covid the part was back ordered so they were very responsive and replaced our furnace under the No Lemon clause. Jack made sure this was done quickly so we didn't have to worry about operating an unsafe furnace. The installer was professional and did quality work. We will definitely continue to use them for all of our future heating and air conditioning needs!

I called All Temp to fix some issues with a humidifier. Not only did they mis-diagnose the problem (they said the humidistat was broken; it wasn't), but the tech also did not correctly reattach the water hose when he was done. Guess what? A couple days later, I have a giant puddle and a furnace that has stopped working because the gas valve got drenched with water. I had to call a different HVAC company to fix both the furnace and the humidifier, which they did easily. UPDATE: All Temp contacted me after this review posted, and went to great lengths to remedy the issue and compensate me for the extra expenses.

All temp replaced my AC and furnace and also added a whole home humidifier in August 2021. The responsiveness of my concerns and questions have been awesome! They even scheduled someone to come checkout a knocking and hissing noise on a Saturday. Explained and fixed the issues for me right away - techs explanations are great, for someone like me that has no idea about how a furnace and AC work. Great value! Very happy with my install, their support and maintenance.

I spoke with Ed at All Temp and he was extremely knowledgable and helpful. He walked me through the steps needed to deal with my issue over the phone and insisted on doing so to avoid incurring the expense of having them coming out over a simple issue. Very responsive, clear communication, and excellent service. Highly recommended.

On Tuesday, the fire alarm in my basement went off and when I checked our bolier, flames were definitely not where they should be. I immediately called All Temp and they sent out Bryan and Luis within a couple hours to come and take a look. They let me know that it was time to replace this 50 year old boiler, and gave specific and informative details as to why. We scheduled an install for two days later. Turns out they were able to get the new furnace installed the very next day, for which I was delighted. Marlon Galvez and his team came out and did a wonderful job uninstalling the old furnace and installing the new one.

They were professional, polite, and extremely informative. Gave me tips on how to maintain the new furnace going forward. They even stayed a while after installation to make sure everything was working properly. I couldn't be happier with the service from All Temp, and will recommend them to my friends going forward. Thank you so much!

This is my second experience with All Temp. Both times they have been fantastic. Today, on the coldest day of the year, my furnace stopped functioning. I called All Temp and they sent a tech (Naeem) over in an hour. He was professional, masked (important in our pandemic world), and extremely knowledgeable and helpful. He diagnosed and addressed the issue quickly. And gave us valuable tips! My prior experience was also fantastic - it was just a couple of years ago now and I don't recall the tech's name. And I forgot to leave a review that time.

Our bathroom flooded into the basement and directly on top of our boiler. In the middle of winter we were left with no heat. I called this company at 10:15pm, David S called me back within minutes. He arrived within 30 minutes and by 11:15pm the radiators were running again. He was able to dry our wiring and get the system running again in no time. I'm so happy with the service we received and grateful we didn't have to wait until the morning which is what other companies told us. Thank you David for your help!

Very pleased. Needed a new furnace for an addition to a house we recently purchased in Glenview. Mike C. showed up on time for a quote and was able to honor a coupon I received in the mail (small space=small furnace). Julio and Ernesto did the installation. They were fantastic! Super friendly, professional and clean. Very careful not to make a mess. Would recommend this company for fast efficient service. Also, all were cautious with Covid, masks all around.

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.

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.

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.

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.
