“A tech was dispatched very quickly and was able to solve the problem in the same visit, even though Ahrens & Condill did not originally recommend or install the mini-split unit.”

“Easy and quick process.”
Easy and quick process. Tim came out to look at our current equipment and was able to right size to a smaller unit for our square footage. Pricing was reasonable. Installers were pleasant. Overall recommend.

Tom & Sean did a great job with the install of our new main furnace and ac units and I was very pleased with their attention to detail. They also cleaned up well. Tim you have some good people working for you. In the 30+ years that your company has serviced our four HVAC units we've never been disappointed. Thanks

Just wanted to thank the Ahrens and Condill team for their relentless effort to make everything right with our recent installation. They were professional, diligent, timely, polite and courteous. There's a reason they've been around forever, no there's at least six of them.

“These guys are top notch - professional, honest, and quick.”
These guys are top notch - professional, honest, and quick. Our mini-split was leaking due to condensation backing up. But we didn't know what was causing the issue and whether the system would need to be repaired or replaced. A tech was dispatched very quickly and was able to solve the problem in the same visit, even though Ahrens & Condill did not originally recommend or install the mini-split unit. There was no pressure to unnecessarily spend money on a new system when there was a simple repair solution. That gives me the confidence to rely on this company. Thanks!

We had Jake out to service our heater, and he was professional, thorough and extremely knowledgeable. In addition to the heater service, he graciously answered several questions we had about the way our water heater was venting. We were super satisfied and will definitely use Ahrens & Condill again!

“Honest, professional, easy to work with, and they stand by their work.”
Honest, professional, easy to work with, and they stand by their work! I needed a minor change after the fact, so when they came in the spring to charge our AC they made the quick change without charging us. We replaced our AC condenser, furnace, coils, and humidifier. Our home temp and humidity is amazing now and they were a much better value and easier to work with compared to the other consults we had. Would highly recommend.

At every stage of the process of replacing my home's two furnaces and two air-conditioner systems -- from assessing the current HVAC needs, to appraising a variety of replacement ACs and furnaces, to providing and estimation, to installation and follow-up -- the Ahrens & Condill team was professional, courteous and dependable. I highly recommend them.

This is the second time we used them for our 20 year old air conditioner. Thankfully they repaired it instead of replacing it. Quick response and wore his mask even though it was scorching out!

“They promptly rescued our family after my Weil McClain boiler block failed.”
They promptly rescued our family after my Weil McClain boiler block failed. Tim helped with the warranty stuff and Shawn and Tom arrived right on time today; and they worked diligently to replace the block -- we had heat again right after lunch! Both guys were kind and courteous to my wife and I. I am very thankful Ahrens & Condill was there when I needed them!
