Testimonials

On 4/10/2025 Blake Retzer had this to say:
Mike has helped me a number of times in the past both on my rental property at my personal home. Always responsive, quick to fix, and fair. Doesn't hurt that he is fun to talk to. Charlie is a great guy as well...both very knowledgable! Testimonial written by Blake Retzer on this site.

On 6/10/2024 Dan V (djv) had this to say:
Great guy, great service. Had to have my unit replaced. The unit was replaced the next day after the very reasonable quote. Install was professional and quick. Job was done in just a few hours. The Technicians that did the job were friendly and thorough. We are very satisfied with the job.

On 10/4/2023 Heather had this to say:
I had looked around 4 years ago when I needed a new furnace and AC unit. I went with A+ The Fix, since then I have called them twice when the AC was not working well. The first time, the outside of the unit just needed to be cleaned off (forehead slap); Mike was so nice and did not charge me. The second time was this morning and he again provided great service, he replaced the capacitor and did not charge me (I assume it was under warranty). Testimonial written by Heather on this site.

On 6/23/2023 Marissa A. had this to say:
I was having issues with my AC unit not turning out cold air anymore and called Mike at A+ The Fix Monday morning explaining that I needed my unit to be looked at. It was looking to be one of the hottest weeks of the year. He came out only a couple of hours later and found that my coil had completely eroded, thanks to my dog using it as a toilet. Mike quoted me on the spot, called and found me a unit and installed the next morning. Not only was he fast, friendly and super knowledgeable, but he beat the prices of any other servicer in the area; including Kettle Moraine air and heating. He even bought and installed a small little fence to put around the unit to deter my dog from peeing on it again. He went above and beyond! 10/10 would recommend to anyone in need of air or heating services!

On 11/18/2022 Terry Klubertanz had this to say:
Furnace went out Friday night. Saturday I left messages with several HVAC places that claim emergency service and got no response. Sunday morning I left a message for Mike, he got back to me with an hour and tried to talk us thru a few quick fixes over the phone. When nothing worked he showed up an hour later. Turns out we needed a new furnace. He gave a quote and left with no charge. He said to consider it a free estimate for a new furnace. He then spent time on the phone Sunday night answering all of my husbands questions. New furnace installed Tuesday at the quoted price and working great. Will definitely be my first call from now on.

FAQ

What devices do you repair?

We fix phones, tablets, laptops, and other electronics—most major brands and models.

Do you offer free diagnostics?

Yes, we’ll take a look at your device and let you know what’s wrong before any repairs begin.

How long do repairs take?

Most repairs are done same-day, depending on the issue and parts availability.

Do you work on both residential and commercial systems?

Yes. A+ The Fix services residential heating and air conditioning systems as well as commercial refrigeration equipment. Whether it’s keeping a home comfortable or ensuring business-critical refrigeration stays at proper temperatures, our team has the experience to handle both.

How do I know if my furnace or AC needs repair or replacement?

If your system is struggling to maintain temperature, making unusual noises, cycling frequently, or causing rising energy bills, it may need repair. Older systems that require frequent fixes or no longer operate efficiently may benefit from replacement. Our technicians provide honest recommendations based on system condition, efficiency, and long-term value.

How often should I schedule maintenance for my HVAC system?

HVAC systems should be professionally maintained at least once a year. Furnaces are best serviced before the heating season, and air conditioners before summer. Regular maintenance helps prevent breakdowns, improves efficiency, and extends the life of your equipment.

What should I do if my heating, cooling, or refrigeration system stops working?

If your system unexpectedly stops working, it’s best to turn it off and contact A+ The Fix right away. Continuing to run a malfunctioning system can cause further damage. Our technicians will assess the issue and recommend the safest and most efficient solution.

Do you help with energy-efficient upgrades?

Absolutely. We can recommend energy-efficient heating and cooling systems that improve comfort while helping reduce utility costs. If you’re considering an upgrade, we’ll help you choose an option that fits your home or business needs and budget.
