A driver in a car with this companies name, on 5/8/25 was driving south on I-43, he was in the left lane holding up traffic swerving back and forth like a drunk driver . He was on his phone.

Best HVAC contractor in south east Wisconsin. If you need to get anything heating or cooling related done, I highly recommend giving them a call. Great employees, great drivers, and great staff!

Their driver nearly crashed into me after illegally lane changing and cutting me off. Their drivers don’t seemed trained to drive properly, be careful around their red vans and van number v7400. I was nearly driven off the freeway by a illegal lane change by van v7400

Excellent service from start to finish. Scheduling the appointment was easy and the technician was knowledgeable and friendly. He diagnosed the issue quickly and fixed it the same day. I really appreciate the honest pricing and quality work.

I have been with first Choice over 30 years. They are an A+++company. Anthony was very informative, experienced, and friendly. Highly recommend.

Anthony is always polite, straight forward and trustworthy. We have a high level of confidence in his work and recommendations.

Cameron was awesome and explained everything thoroughly and in language we could understand. I highly recommend First Choice!!

Justin was great! Great communication, took time to explain things to me. Highly recommend.

I’ve been using 1st Choice for all of my HVAC needs for 20 years. Always punctual, always professional and always priced fair. I highly recommend their service.

Nick L. Was an excellent service technician..I had alot of questions and he took the time to answer all of them.

Nick was our service technician. He took the time to explain what he was doing and why. He was very knowledgeable and courteous and completed the maintenance check in a thorough and prompt manner. But he didn’t bring us lunch🤣😂 JK. We are very pleased with 1st Choice for our furnace and AC needs. We have always had good, reliable service.

I have used First Choice Heating And Cooling for many years, and Justin is truly A professional. He is respectful, prompt, thorough, and honest.

1st Choice was amazing during our furnace issue from start to finish.

We noticed the temperature in the house was 2 degrees cooler than it should have been, and saw the error on the thermostat. It was late (after 6pm) on a Thursday, and within 30 minutes of my call, Tim was here. Tim was great. After a fairly quick investigation, he said "these are the conversations we don't like to have". Our Carrier furnace from 2011 had failed due to a common known issue in the industry. Tim said he could get an advisor here the same night to go over options.

Brandon was here within 30 minutes of Tim leaving, he did some data collection on our set up and then asked what we were interested in. The fix for the furnace was almost the same price as a new furnace. So we selected a new furnace. Brandon respected our choices while advising us, which we appreciated.

The next morning, before 9am, we got a call from the office letting us know we'd get the furnace installed in the afternoon. This is the day we got around 5 inches of snow in late March as well, so our house was getting cold. Everyone we talked to at this point offered to supply us with space heaters too.

Keith and Mitch showed up around 1-2pm on a Friday. They stayed until 7pm to make sure our home had heat. They were open and willing to answer any questions we had. They had to redo our intake and exhaust piping to be to code. Again, they were awesome, walked us through the new thermostat late on a Friday like they were here during normal working hours.

I know temperatures are an inexact science with thermostats, but our old system was usually set at 70 during the day and 68 at night. 68 felt cold in the morning. Sometimes 70 was cold during points while watching tv at night. With this new system, we had it set at 67 and were hot, and we bumped it down to 66 now, and are loving being comfortable again.

The point is, we got a new furnace and it feels like we got a new, better furnace, which is what I want when I make a big purchase.

We appreciate all of the people who helped us from 1st Choice.

Having recently needing an air-conditioning unit, Boiler, and mini split Justin came out and did a good job of trouble shooting and explaining our options. They were able to come out the next week Rob and Chris installed all three units. They were professional did a great job. Definitely will recommend 1st Choice Heating and Cooling

Tim does a great job of explaining the problem and what the best course of action is. We enjoy working with him very much.

1st Choice was super responsive when my AC went out last week! They offered an emergency same-day option, but I scheduled first thing the next morning. The technician was friendly and tried to find a temporary fix for the weekend heat, but the unit was simply too old.

I requested a ballpark replacement quote, which seemed high—and after getting five more quotes, it turned out to be the highest by far, in some cases nearly double other well-known local companies. Great responsiveness, but pricing was not competitive in my experience for a new unit.

Guy that came was great. Very knowledgeable and was happy to show me and explain everything he was doing. Resolved my problem and gave my good guidance going forward.

Anthony Deregowski was very professional & nice. He explained everything very clearly & thoroughly so that we could make informed decisions about our boiler.

Tim was amazing. He made sure to share his findings, including pictures, and explaining the readings in the pictures and what they meant. He made it easy for me to understand what happened to the air conditioner. Plus, when reviewing the repair options he took the initiative to suggest having a rep come out to quote a new unit since cost of repairs were almost the amount of a new unit. He wanted us to know all our options before making a decision. Perfect service.

Nick did a great job of explaining everything he completed, he was very thorough . I especially appreciated his friendliness with our dogs. He took the time to say hello to them. Overall I highly recommend this company.
