Air Alliance Team

One room in our home is heated with a closed-cycle hot water radiant heating system embedded in the floor. It wasn't heating. Most companies in St. Louis lack expertise in this type of system, but Bill came out and fixed our problem quickly and efficiently.

The team at A's and Sauer really came through with a reasonable price. They added 4 vents and 2 returns in the new basement I am finishing. They also added the bath fan vent to the outside and installed the fan for me. As an extra help they took some time to fix an issue with my furnace as well. No question who I will call next time. It's the local guys from A's and Sauer!

My A/C went out last summer on a Saturday. It was almost 100 degrees outside and I was really worried no one would be able to help until Monday. Air Alliance responded very quickly, they were there with 45 minutes of me calling them. My AC was repaired and for a very reasonable price. I highly recommend their services!

We have been customers of A’s Heating and Cooling, now part of Air Alliance for 25 years! I would never consider using any other company. Steve Aubuchon sets the example for the company through his honesty, knowledge and fairness. I recommend them highly!!

This company does the maintenance for the air conditioner. After their job, four of the air conditioners stopped working. And they come back to to charge service fee with different reasons.

I was told that I needed a part for my furnace that would cost $800 and would not be in for a couple of months so the only thing I could do would be to get a new furnace. After further research I found the part on Amazon for $200 received it the next day and had it installed. I would never use this firm again and can't recommend against them enough.

Twice they have been able to accommodate us for same day AC service and they left us nice and cool on two 90 degree days, one while we had a 6 day old baby at home.

Great service and great rates on repairs and good honest explanations from the techs.

The only guys we call.

Have purchased a furnace, air conditioner and high efficiency hot water heater. Brent always ensured I purchased the right product for my needs, offered a fair price, and excellent service and installation. I would highly recommend them.

We woke up Monday morning and our furnace wasn't working. We called Sauer Cooling and Heating and they were out fast and had us fixed in no time! They were great to work with! I highly recommend them!

Outstanding customer service. Their responsiveness, friendliness, and honestly can not be overstated. Whether routine maintenance, repairs, or equipment replacement, Sauer has been awesome to work with and has earned a committed customer.
