Just had a new central air unit installed 85* outside! The 2 technicians that did the job were extremely professional and definitely know what they're doing, couldn't be more pleased . Only took a short break and then back on it. My hats off to them. Thanks guys!

On 6/20/2025 Dean Willaredt had this to say:
We have been thrilled with the great service from Steffen's! They have always worked hard to take great care of us, even when their supplier has a delay they work to get things working. They also recently changed out a bad furnace for us at a building at a super good price and very fast. They are friendly, helpful and you can trust what they tell you. Great people!

On 6/12/2025 Whitney Love had this to say:
My air conditioner unit was working too hard trying to cool down my house and not getting the job done... So I put a call into Steffen. They were able to come out the same day And get my system back on track, blowing cold air. They also discussed with me next steps for the next few years about whether or not I would need to upgrade my HVAC and what Freon cost might look like. I appreciate their expertise and willingness to work around my schedule to get the job done! Thank you!
