Success Stories

Our customers are our best advocates. Explore their success stories and see how Arnold Air and More has made a difference in the St. Louis community:

The person I worked with was great! He came as scheduled, on time, and professional, and provided us an estimate that same day for our new A/C and Heating install. I had several questions which he answered immediately. The quote was detailed and reasonable. I liked that he did not try to upsell me. He listened to what was important to us: noise level, air filtering and energy efficiency, and, of course, cost. The installation was completed in one day and everyone was very professional. Highly recommend!

Becky B.

We have used Arnold Air for a few years for repairs and maintenance on our old system to the newly purchased HVAC system and humidifier this year. We have been impressed with every experience. Prices are reasonable, technicians are friendly and professional, the company is responsive and helpful! I definitely recommend Arnold Air.

Denise W.

On the hottest weekend of the year my A/C went out. I went home to meet the repair guy and he was right on time. He turned my unit on and diagnosed the problem immediately. It was my condenser. He had the part with him and in 5 minutes my unit was fixed! He was very thorough and fast. I highly recommend this company. They are prompt and professional and prices are competitive. If anything goes wrong in the future, they will be my first call.
