The whole record
Not every review is five stars
On October 27, 2026, Google showed 441 reviews for A-1: 426 five-star, 6 four-star, 1 three-star, none at two stars and 8 one-star. Two of the one-star ratings include a written review, and both report a missed appointment. One is below, word for word, with Mike’s reply; the other is on Google with the reply posted to it.
1 out of 5 stars
“Set up an appointment for an estimate, nobody showed up”
Cory M. · 1 of 5 stars · Google review
Reply from Mike Vinca, on Google: Cory, I could not find an appointment under your name. A missed estimate with no call is not how we operate, so if you booked with us, call me at 414-595-5175 with the date and I will find out what happened and make it right.
Why the reviews read the way they do
Most of them mention the same three things: the phone got answered, the price was the price, and the problem got fixed. That is the whole business model. When you call A-1 you get Mike, the owner, not a call center; you get a flat-rate price before any work starts; and you get an honest answer about repair versus replace with the reasoning on paper.
If we ever get it wrong, tell us. Mike reads every review and would rather fix a problem than argue about it.
Emergency right now? Call or text 414-595-5175, any hour.
Request service or a free replacement estimate
We call you back during business hours. You get a flat-rate price before any work begins, and repairs are guaranteed for one year, parts and labor.
Rather pick a time yourself? Book a tune-up, free estimate or repair visit online, any time of day.

Why Milwaukee calls A-1
Big-company standards. Local-shop accountability.
Flat-rate pricing, quoted first
You approve the number before a tool comes off the truck. No hourly surprises, no upselling.
24/7, and no call center
After-hours calls ring Mike’s cell, not a call center. If he is on another call, text or leave a message and you hear back quickly.
Authorized Lennox and Rheem dealer
Factory-backed equipment and warranties, and we service every brand you already own: Carrier, Trane, Goodman, York, Bosch, Mitsubishi and more.
Repairs guaranteed 1 year, installs 10
Every repair is guaranteed for one year, parts and labor. New Lennox and Rheem installs registered with the manufacturer carry a 10-year parts and labor warranty, with limited lifetime heat exchanger coverage on select models.
