Best Heating & Air Conditioning / HVAC In New Lenox

“Great 1st time experience with Zark. I reached out on August 9th to have our AC unit looked at and they were out that following Monday August 12th. Our AC was continously running and not turning off. I explained to our tech Bill the situation and he was able to find the issue fairly quickly. We had a leak on the high side Schrader valve. A new core was installed and the unit was charged with refrigerant. The unit has been working great now. Since the install was done by another company that since has retired, Zark absorbed our account and honored the warranty and there was no charge for service and repair. I will be using you guys for future PM's on our HVAC equipment. Thank you“

“Amazing customer service and quotes were not inflated. Very pleased with the recommendation for my older air conditioner and price for coolant.“

“I just wanted to let you know that your folks did a great job helping me out at the house with our old heat pump that wasn’t working. Given the weather, and I’m sure the volume of issues they were working with, they did a great job of getting back to me right away and coming out to see what was going on so quickly. They were really good and nice people to deal with! What a good job they did, I really appreciate it.“

“I’ve been communicating with Marco for about 4 months he sent a tech out in February to assist with my replacement of my AC unit. My warranty company has been very difficult to communicate with he has contacted them on numerous occasions at times he was more successful than I was but make a long story short we are now in process of Marco and team coming out to install my new AC unit he has been very patient with the process thanks Marco“

“Amazing service. Fast, professional and polite. You really won't find a better service for the price. trust me i've looked.“

“The technician showed up right before the scheduled time. He cared for everything – from furnace duct cleaning to humidifier and furnace maintenance. And the best part? He tidied up before heading out. The process took about 3 and a half hours, and then he was off. I've got to say I'm satisfied with the service!“

“Very happy with the service they provided. Paul was super to deal with, explained everything and gave me options on the repair. Very professional service and would gladly use them again.“

“Jeremy Adams performed an outstanding job diagnosing, ordering and repairing my AC unit. He consistently checked in and urged the Supply House to track our order as it took several weeks to get the correct parts in. He was very professional and courteous through the entire journey. I will continue to use this company and request Jeremy to perform the work. I'm sure everyone else there is great, but I just had really great experience working with Jeremy. Thanks for all your support. Mike“
