“We needed a new dang a/c in the burning miserable heat of summer. Other companies gave us the run around if they even got back to us at all. Airpro came out immediately, were incredibly nice and friendly to deal with. They had an entire new a/c and coil installed in no time. Back to happy life. Other companies said they couldn’t get to us or get the unit we needed. Airpro was really great to work with. Pretty sure my wife is going to make out with me more often now because she’s so grateful for conditioned air again. I credit Airpro. Melissa, Dan, and the install team were all wonderful people. Highly recommend.Service: Installation“

“We have used Kirkwood Hog & Cooling for 12 years. We have had consistent, fair, professional and knowledgeable service. Our A/C froze this week in the extreme heat. Our technical, Ricky A, was great. It proved to be more difficult than just a frozen system- of course. He went to get a part , found out it was back ordered 45 days so took our old part to the shop and worked on it to make it usable. He didn't have to do that. We appreciate his time and talents.
We also have a very old boiler which we are nursing along with the help of Gary. He is our 'boiler whisperer'. WE don't want anyone else touching it.
Kirkwood should be your first call, they will do right by you!“

“Outstanding service - our renters AC went out on a 100 degree St. Louis day. They went out after hours to review the situation and within 24 hours had parts delivered and service completed. Very happy tenants. Highly recommend“

“Work was done on time and all. Issues were resolved.
Technician was thorough and courteous“

“I called Tim last Fri afternoon because my furnace was making an unusual noise and I hadn't had it serviced in a couple yrs... he was here within about an hour. My furnace was very old, so I was prepared for the worst... and, of course, that's what I got!! Tim took interior pictures that showed so much rust and erosion that it obviously needed replaced. What I did not expect was that Tim would find several install mistakes with my 2yo second furnace. One of which, was an improper intake vent that was actually pulling carbon monoxide from the other furnace and feeding it into our bedrooms!! This explained our ongoing and recent health issues, so I immediately shut that furnace down!! Tim and his crew were back Monday morning and replaced my older furnace. They returned Tuesday morning to properly rework my second furnace. Tim and his crew were very courteous, clean and worked efficiently. And, in my mind, he may have saved our lives.... so, I highly recommend Gordon's Heating & Cooling.“

“Confirmation of appointment by text and included a picture of the technician. Punctual. Appropriately covered with shoe shields and mask. Polite and inquisitive about my experience with the furnaces/AC's. Gave me some advice. I am confident that I received great service. Highly recommended.“

“Chuck was amazing! Honest guy and best price. We are very happy with the work him and his crew did“

“Our 18 year old air conditioner died at the end of spring, Merten's responded to us very quickly and came out with a very competitive quote for a new HVAC system. Upon walking through our 115 year old home they also provided good recommendations on home improvements we could make to increase the efficiency of our system. On installation day they were on time and very respectful of our home, and were always very friendly. Highly recommended“
