“My AC was not working and my place was feeling 80+.”

My AC was not working and my place was feeling 80+. I had to sleep without any blankets. It was no fun. So I decided to contact Atomatic and within 24 hours of initial contact they had 2 techs come by and everything was fixed and felt amazing in my place. It timed up perfectly as it was right before a 100 degree weekend in Chicagoland. I highly reccomend calling Atomatic if your home AC is not working!

“A new A/C unit was installed during a period of temperature in the 40s.”

A new A/C unit was installed during a period of temperature in the 40s. As the temperature increases a few days later the technician Joe, came out to try and adjust the A/C discharge air. He was willing to return on a Saturday morning to finish the adjustment, we therefore had a working unit, thanks to Joe’s dedication.

“Was amazed how quickly Landmark Heating & Air Conditioning responded to my call of desperation.”

Was amazed how quickly Landmark Heating & Air Conditioning responded to my call of desperation. My furnace went out during the before our Memphis cold weather hit in January 2025. Installers were here the next morning; my new furnace was working that day!! Workers were polite, efficient and professional.

“Have a condo with a building supply heat pump HVAC system.”

Have a condo with a building supply heat pump HVAC system. I was having high pressure faults. Atomatic did a great job in methodically finding and resolving the problem. I appreciated them showing me the issue and the tips on how I could improve the maintenance to reduce future risks. Very personable and methodical. Great service!

“All of my buildings HVAC systems over the last 8 years have been maintained by Atomatic.”

All of my buildings HVAC systems over the last 8 years have been maintained by Atomatic. They have always went above and beyond when called upon. Just yesterday we had a Frequency drive and a 40 horsepower supply fan motor get fried and Atomatic was quick to respond to our medical office building. They assessed the situation on site and sourced parts right away. These guys had my unit back up and running with all new equipment by the evening. I was shocked that they were able to access parts so quickly and come through to save the day. I want to thank Bruce, Alex and the rest of their install team for such a quick turn around. I also would like to recognize Alex our sales rep that had a big part in procuring the parts needed, especially after hours. You guys are great! Thank you all.

“It was an absolute pleasure to work with Atomatic.”

It was an absolute pleasure to work with Atomatic. From the woman who called me to set up the timing of the service call, through completion of the repair we were impressed with how friendly, knowledgable and helpful everyone from Atomatic was. The service technician Adam came out and was impressively helpful. He not only resolved the problem, but did some on-the-fly education so that if the problem arises in the future I don’t shut the power off to the furnace while trying to reset it and making it impossible- to see the trouble code…like I might have done this time. He worked quickly in the face of interruption as he patiently answered loads of questions from me initially and then (no doubt very similar questions) from wife after I left to go to a meeting. He cleaned and tested our furnace, was candid about how old the system was and what needed to be dealt with immediately and the longer term prognosis for the furnace. At no point did I get the feeling I was being “upsold” like one gets with some businesses where you as a customer lack technical knowledge. When he was finished he left the space cleaner than he found it. On his way out he made sure that we had his contact information in the event it failed again in the night. My expectations were thoroughly exceeded. I think “emergency call” and I expect someone to arrive late and to at-best hurriedly fix the issue while dumping my wallet into their tool bag while telling me the whole things needs to be replaced and I need to get a bushel basket of cash, maybe two just in case. All in all I appreciated their help!

“Have used Atomatic for 8 years since I bought my home.”

Have used Atomatic for 8 years since I bought my home. Professional, punctual and very knowledgeable. The service contract is not inexpensive but I have always felt I have gotten what I have paid for. And I trust this company will not gouge me as well.

“I can't say enough good about Atomatic.”

I can't say enough good about Atomatic. Service is par excellence and the technicians are efficient, very competent and personable. They definitely are proficient in their knowledge of the workings and maintenance of HVACS. I have had a maintenance contract with Atomatic for many years and I am more than happy with their service. Atomatic is the best of the best.

“My furnace stopped working on a very cold day.”

My furnace stopped working on a very cold day. I called Atomatic and they said they were booked for the day, but could squeeze me in. Ivan arrived and quickly diagnosed the issue. In very little time, my furnace was up and running again. Ivan even took the time to show me how to program the thermostat to save on my gas bill. Between the lady on the phone squeezing me in and Ivan’s quality work, I highly recommend Atomatic!

“Scheduling was easy to do and handled politely.”

Scheduling was easy to do and handled politely. The tech showed up on time, was thorough, helpful and explained the issues with my A/C. Also, they use mobile devices to quickly communicate pictures, problems, trouble shoot and were able to get me a preliminary quote for a replacement furnace in minutes. I have now used Atomatic for 4-5 years of annual HVAC maintenance on my two units and continue to be pleased with the company's people and service.
