I have been a customer of STRAMOWSKI for over 30 years. All the technicians that have come to give our furnace/air conditioner unit a winter/summer tuneup are wonderful. They inform us of issues or no issues. I recommend them for all your furnace/ air conditioning needs.

After three different companies taking a look at our AC, Stramowski Heating was able to identify the issue, and fix it in less than a few hours. Profesional, proactive, and gives you detailed work summary.

Hottest day of 2023 is when Stramowski Heating really shined. Called in the morning. Brad was there to fix the problem in the afternoon. Better service than Amazon! Amazing.

So many companies take their time getting back to your inquiry, or don't respond at all. Not Stramowski... I heard back the next day. Tyler was here on the scheduled date, on time; was very personable, professional, and thorough. He even went the extra mile to clean up water from my basement floor (not in his way, not affecting his work on my AC unit), and did not charge me for it. I had such a good experience with Stramowski, and am thankful for a company with integrity, that I can trust. I highly recommend them!

I have been consistently impressed with the service that Brad offers. He is clear about the state of our heating and cooling systems, clear about any necessary or recommended repairs and their costs, and is an altogether pleasant person.

Service technician Tyler consistently provides exceptional professionalism, punctuality, and leaves the working areas impeccably clean. I cannot stress enough how grateful I am for Tyler's ability to establish a friendly bond with our colossal dog, who typically barks incessantly at unfamiliar faces, causing quite the commotion. Stramowski Heating undoubtedly boasts a team of remarkable employees!

Called Stramowski after the guys at A-1 Milwaukee heating and cool wanted to replace unnecessary components in my A/C that had stopped working. Kyle was able to diagnose what the issue was within a couple minutes and, took the time to show me on the testing equipment why the components that needed replacing were failing. He even took my hose and showed me how to properly clean the fins on the unit. 10/10 for service and overall value.

From the first phone call I knew Stramowski Heating was going to take care of my emergency furnace needs. They came that same day and gave a quote. The next day I had a new furnace, AC and water heater. Great service and installation. This is place to call if you're in need of service or an entire new unit(s).

Have used this company for years for my annual service on furnace & AC unit. Technicians are always on time, friendly, knowledgeable and address any concerns I have. They never try selling me anything and take the time to review services done and ways to keep my units running properly.

We have used Stramowski for several years. They are always prompt, responsive and skilled at what they do. Nothing has ever required a call back to finish or fix what was supposed to have been fixed before. Good people, solid work, consistently excellent results. Very simple: use them. Very pleased.

The tech showed up and installed a new zoning system and dampers due to failure of our old system. They put drop cloths down over our machines, kept everything super clean and were quick. The workmanship was superior, I would recommend using Stramowski.

Came home after a long, hot day and our house was 80F inside. Sent a note to Stramowski Heating at 12:30 am. Kyle arrived this morning and showed me some maintenance tricks, changed out our fuses and capacitor. I couldn’t imagine a better experience and I’ll will happily recommend them to anyone in the Milwaukee area.

Great professional service. Very thorough, and made improvements to the installation when replacing my current HVAC system. Follow up service was equally professional.

Had our ac go out and got service in a timely manor on a very hot day. The service technician was friendly and helpful, explaining how and why the issue happened, and showed us how to maintain our equipment properly.

Working with Stramowski is great! We are on their annual maintenance plan where they contact us to schedule PM service on our furnace and ac. This is great because with busy schedules, we tend to forget. The technicians are experienced. We could not be happier. We are fairly new customers of Stramowski but will be long time customers.

The technician was very responsive and honest with the assessment of the issue. They were quick on the true part repair as well. We have a boiler so not only without heat but also without hot water as well.

Contacted Stramowski at 3:00pm on a Friday with temps in the single digits and falling. We had no heat and Kim, who answered the phone, was very kind and reassuring. She said a technician would call when on his way and it would be no later than 6:00 pm. The tech came at 4:30, he was friendly, polite, and got right to work. He had our furnace fixed and was out the door by 6:00pm! Could not be happier with the friendly and competent service we received.
