What people say

I have one rental property in Deerfield. As soon as the tenants noted the air conditioning was not blowing cool air, I made a service appointment with Atomatic, the only heating and a/c company that we use for our homes for over a decade. Due to the heat wave, the soonest available appointment was Friday, May 13. I booked the appointment yet continued to receive urgent requests for assistance from my tenants. The condo is on the 2nd floor above garages and reached over 90* during the day.

After calling the emergency after hours line at nearly 8 PM, Joe, the technician on call, returned my call within four minutes. This was the first example of how Joe exceeded my expectations for exceptional customer service. Not only was he friendly and personable, Joe went out of his way to ensure my tenants were able to get some relief in a cool and comfortable environment after a blistering day. Further, with the tenant's permission, I candidly let Joe know that the tenants had a positive COVID diagnosis 10 days ago. Taking into account the long hours, the heat, the late hour of day (I believe it was nearly 10:30 PM when Joe was able to make it to Deerfield) and the info about the tenants, Joe still made the trip to check out the air conditioning, while taking health and safety precautions, and refill the coolant.

Atomatic has been in my life for over 20 years for furnace and A/C services. Each of the service engineers who has come to my home has always been professional, courteous, kind and knowledgeable to include Bill Jacobs who was my initial service engineer for a number of years. Joe Kovalcik has been coming to my home for these past three + years, possibly more, unsure of the time frame; but, again Joe has maintained the exemplary work expected of Atomatic professionals. These service engineers are down to earth and know what customer service is all about. Just want you to know their representation of your company and themselves is noticed and much appreciated. I also appreciate the folks in the back office who support the other side of the business. I couldn't pick Mary Warner out of a crowd of one, but she is a gift!!!!
