Did an amazing job on my system. Explained everything that had to be done. Good price for the work. Also very professional and polite. Will use again if I need to.

Oh my God these guys are wonderful. It came out within hours. I found a serious problem out with my furnace and had it replaced and a few more hours. Unbelievable service I was so worried that I was going to have to take off a few days of work. Plus they left the house cleaner than that was when they got here.... Thank you so much Chris for all your help. I will definitely recommend you to friends or family.

Always a great day when Zark shows up to inspect the furnace before the frigid temperatures! Great job as always! 5 Star ⭐️ company!

Woke up to furnace not working. Sent a text around 6AM and Zark answered within 5 minutes. Zach was at my house 30 minutes later. Furnace back up and running in 10 min.
They are honest and do not upsell you on items or services you don’t need.
That’s Zark for ya.
Hands down the best!!!

Very impressed with Zark’s team that they sent out. Dan who was the lead installer took his time on installing the new furnace and A/C system and everything came out looking great and professional. Great experience. Highly recommend!

Zach was thorough and took the time to walk me through what needed to be replaced, which I really appreciated!

Great team. Quick replacement of our furnace. I would recommend Zark to anyone.

Zack was very polite & explained everything very well. Zark Heating & Cooling is very professional & reasonable pricing. Highly recommend.

Rob and Zack just installed a garage heater. Looks great, works great and very clean work. Two very cool guys and I highly recommend. Thank you guys.

They came within an hour of calling on a Sunday morning, we had no heat they fixed it and explained everything. This is the second time we have used them, very happy with the service. Very responsive, very nice.

I had an excellent experience with Zark Heating and Cooling Inc! They were able to fit me in the same day, which was a lifesaver during this heat wave. The technician arrived promptly, quickly diagnosed the issue, and clearly explained what was wrong and how he was going to fix it. He was polite, professional, and clearly knew his stuff. My AC was up and running again in no time. I really appreciated the transparency and efficiency. Highly recommend Zark Heating and Cooling Inc for fast, reliable, and courteous service!

These people are great. Furnace wasn’t working the day after Christmas and the owner showed up 30 minutes later and fixed the furnace promptly. Couldn’t believe it right after a holiday.

Zach provided great service during his visit. And recommended Zark for all my furnace needs

I honestly cannot say enough about Zark. They were here ahead of time however they did wait until the appointment time to ring the doorbell which I extremely appreciate. They were shoe covers and placed drop cloths down from the front door down to my basement. Everything was extremely clean and organized and very professional. I had my entire air conditioner replaced through them and I could not be happier. I will definitely be using them in the future!

We are very grateful to Bill from Zark Heating and cooling today. Our upstairs air conditioner was not working and Bill worked very professionally and productively to get our 20 plus years unit working smoothly. The Zark technicians always do a great job and care four our heating and cooling needs. This is a great company.

They were there when they said they would be. explained everything to me A good experience. Very polite. I felt it was a very reasonable price compared to other places.

Zark was great! Fast emergency service and honest assessment. Always my goto for hvac needs!

I called this morning with furnace issues and Rob was here a couple hours later and had it fixed in no time. Top notch company and technician! I will definitely recommend to anyone needing any hvac service!

A very satisfied customer here! Thank you, Bill J. for another great service, top notch customer service and valuable advice. I really appreciate the booties. I wish every company have their employees wear booties when entering a customer's home. It's common courtesy.

The service was outstanding and the total price was much less than their competitors! I would highly recommend Zark for professional and friendly service. They are truly a family run and owned business!
