Zark Heating & Cooling Inc.

Rob is by far the most professional person in this industry that I’ve ever known. I was shopping around for different quotes and things I wanted for a new furnace and AC unit, and I wasn’t having a lot of good experiences with people and their professionalism. So, I gave Rob a call and had him come out to give me a quote, and I had a bunch of questions, and he answered every single one. Over the year that I have learned different things about these systems, and HVAC altogether, there were a few instances where I could’ve been screwed, but Rob did not. Everything was top-notch, 100%. He really cares about his profession and wants the customer to have the best experience possible. The installation was awesome. A few weeks later, there was an issue in the furnace (NOT Zark’s fault), Rob was able to quickly diagnose and find it and fix it within minutes. A year later, I got my first annual service on the equipment and inspection and everything is the day it was installed. In a world that is unrecognizable today, it is nice to see honesty and passion and kindness. His prices are also very competitive I believe they’re really is nowhere else to go in the area for HVAC. So thank you for this.

Alex and Luis installed a furnace in our home and they were amazing!! Very professional yet friendly, knowledgeable, and quick! They are the best! I will recommend Zark Heating & Cooling to everyone!

I use ZARK for maintenance on my heating and cooling unit. I have had 2 separate instances where my furnace wasn’t working and it was cold out. I called and spoke to Kristy who had a repair tech come out that day to fix my heat. I was so thankful that someone could come out so fast and fix my unit. I would also like to say that I am a single mom and their fees are affordable. I signed up for a yearly maintenance plan so this way ZARK comes out and checks my furnace to make sure everything is running well for the upcoming seasons. The techs are professional and very nice. The service is great and so are the employees. I highly recommend ZARK for your heating and cooling guys!!!

Zark is fantastic! We are always very satisfied with our service from them. Dan was out yesterday to check on an issue with our furnace and we were so happy with the work he provided. We ended up needing a new furnace, and they were able to get us in the next day. Everything today with the install went great and was done very quickly to get our house warmed quickly. They’re always very professional and offer great, honest advice.

We recently had our control board replaced by Zark. Bill and his associate did a fantastic job at diagnosing and fixing the problem. I appreciated their thorough explanation as to the problem and felt they were 100% honest. We found Zark on the New Lenox what's happening Facebook site and they came highly recommended. I would definitely recommend them as well.

Zark Heating and Cooling has maintained my furnace and AC for a number of years and have been able to update my water heater when it started to leak. By handling my furnace maintenance they were able to foresee when I was in need of a new furnace and humidifier. I recommend them to my family and friends. Their associates are friendly and knowledgeable.

Zark heating will be my new furnace and air conditioner check yearly and repair service company! Rob was very knowledgeable and I was very pleased with his work! I never write reviews but I wrote this one because it is hard to find a company like this one!!! Very Pleased! Will refer to friends and family!

I had a great experience using Zark. They were knowledgeable and honest when it came to my repairs and why it made sense to replace my a/c unit after refilling the coolant didn't work. Price was very fair and significantly less than the major HVAC company in the area.

Very happy with our recent installation of a whole home humidifier. Dan and his crew were very polite and on-time for the job. The installation was quick and tidy, and Dan did a great job explaining the unit after he was finished. I would definitely use them again for any HVAC related issues I have in the future.
Thanks again guys!

I had a unit with the furnace (which is about a 20 year old unit) not functioning properly on the coldest day of the year. I called Zark and they were out there within 3 hours. They fixed the issue and it has run like a dream since. Would highly recommend.
