Customer Testimonials

There’s a reason why Kingdom Air has been able to serve Southwest Indiana for over 35 years—our commitment to honesty, quality, and treating every customer the way we would want to be treated. Many of our customers have trusted us for decades, calling us not just once, but time and again when in need of service. We installed their system decades ago, and when it reached the end of its life, they chose us to do so again.

At Kingdom Air, we believe in doing right by our customers, standing behind our work, and building relationships that last. As Proverbs 22:1 says, “A good name is more desirable than great riches; to be esteemed is better than silver or gold.”

We are honored to serve our community and grateful for the trust our customers place in us. Here’s what they have to say about their experience with Kingdom Air.

Kingdom Air Customer Reviews & Testimonials

"I wanted to take a moment to give a shout out to Chris Wilson. Chris stopped by our home on Friday between 4:00 – 5:00. We can only assume that we were probably his last stop of the day before heading into the weekend.

We were not originally on the schedule that day. We were worked in that afternoon because we were having issues with our thermostat. Knowing we were the last stop of the day (not to mention an add on) we were hopeful that it would be an easy fix for the technician and that he could be on his way.

At the end of the business day (especially on a Friday), one would expect a technician to be less than thrilled to hear that he had an add on at the end of the day and obviously be in a hurry to get in/out. That was not the case with Chris. He was very well mannered, very polite, very patient, very professional, and very thorough from start to finish.

He never once looked at his watch or made us feel like we were an inconvenience at the last minute heading into the weekend. It was a pleasure meeting him and having him in our home.

Please relay our “Thanks” to him once again and please pass this email along to his Supervisor for review. That young man indeed deserves some recognition."

"with propane gas prices soaring, my wife and I started to research alternative and more affordable methods to keep our house warm. We learned that there was a heating/cooling technology called “Geothermal”. After many phone calls to contractors in and around Bloomington we found nobody who could install such a system in our house – but somebody recommended we try Kingdom Air. We were a little hesitant at first since they are more than an hour away from Bloomington. But after a phone call and a visit by Bob Graber to make sure our property would work out we requested a quote.

From that moment on everything went very quickly. In late Summer we had a Geothermal heating/cooling system and it has been a great investment. While this system is fairly maintenance free it requires annual checkups. We had a few emergencies – these things always happen when it’s super cold or scaldingly hot. Every time the problem was solved quickly either via phone, email or personal visit. The one hour drive from Cannelburg was never a problem.

This summer we replaced our 15 year old Geothermal unit by a brand new one, made in Indiana. Again, Kingdom Air came in the morning. Four people worked to put in the new unit and before 4pm everything was done. We are glad that we hired Kingdom Air to install our Geothermal system 16 years ago and the fact that they have been maintaining it and installed the upgrade this year makes it very easy for us to recommend them highly."

"After my furnace started acting up, contacted Kingdom Air, and they quickly had a tech out to diagnosis the problem and for safety reasons, decided to install a new heating and cooling system. They were able to provide affordable financing, and quick installation.

Tyler G. and Chris W. got everything removed, and new unit in place in a professional manner. Made sure to go over all pertinent details, and did a super job."

"The whole crew is great! They got my old unit up and running, scheduled a replacement unit for a few days later, and had my AC unit swapped in half a day. Everyone is very professional and friendly, and the price was great! They’ve earned a repeat customer for any future heating and cooling needs."

"Kingdom Air Heating and Cooling provided exceptional service when our air system stopped working. Logan Smith responded quickly, and after arriving at our building, he efficiently assessed the situation and fixed the issue. He was not only knowledgeable but also friendly, taking the time to explain everything in a way we could easily understand. Logan was patient with all of our questions and made sure we felt comfortable with the process. When he returned to complete the work, he was fast, clean, and efficient. We couldn't be happier with his professionalism and the overall experience. Highly recommend!"
