911 Heating & Air, LLC

Just had my fan capacitor replaced for my central air unit. Service was great. Driver stated he’d be at my residence within
30-45 minutes in which he was there way before. Tech was very fast and friendly. I’d recommend these services to anyone I know that may be having any heating or cooling issues. Thanks 911 heating and cooling.

I have known Alex of 911 heating & Air, LLC for two years now and all I can say is I wish all businesses were run this way. Honest, reliable and affordable. Alex is not just book smart but can actually trouble shoot and work with his hands. He cares about his work and his customers. I am a retired electronic technician and electrician of 36 years and HVAC electrician of 4 years and I an totally impressed with Alex's work and ethics.

I called 911 heating and air for a 2nd opinion on my furnace after the 1st company I called told me my furnace was junk and unfixable because the 2ndary heat exchanger is not changeable due to it being welded in. 911 informed me of my unit being on recall and that they were able to fix/change the heat exchanger under recall. Alex was honest and very professional on updating the current status of my furnace. I highly recommend to anyone who is looking for a honest reliable professional company to fix there furnace or ac unit. 911 heating and air will have my business for now on!!

repaired our unique radiant heating system after two other contractors gave up.
Alex was patient, professional and very knowledgeable about what our options were to repair this system.
I would highly recommend 911 heating.

These guys are the BEST! They responded to my emergency situation (furnace dying the Friday night before New Years - when my former HVAC company was closed and the answering service was turned off). Jefferson and Alex got on it right away - tracked down a new unit and spent New Years Eve at my house making sure that it was up and running for heat in the New Year!!!! At the same time I quizzed them about central air for my late 19th Century house and they evaluated my situation and offered me a package that was too good NOT to include, along with flexibility in scheduling the installation. With the arrival of Spring, (and COVID-19), I put off the A/C install for awhile, but when I was ready, so were they. We were able to schedule the installation within a few days, and it was all handled with great professionalism and respect for my time. They took the time to answer my questions - even the dumb ones - with clarity and patience, and made me feel like having my furnace die at the end of last year might just have been the LUCKIEST thing to happen to me (they even got me a discount on the compressor unit because there was a ding in the metal housing). For the first time in I can be anywhere in my house even on the hottest and coldest days, and I know that if anything ever comes up with the unit, they will be there for me. Honest. Dependable. Trustworthy. Skilled. Client-focused. Pick the sterling adjective and these guys will be your "go-to" for your HVAC needs. Thanks again Jefferson, Alex (and brother Andrew).

Called 911 yesterday for an A/C repair. They were over in 2 hours; all the while communicating arrival time! They were fast, friendly, thorough, and above all honest! I was given the facts in terms that were easy to understand and then given some realistic options...no pressure! Really pleased and would highly recommend 911! Plenty of big name options in and around Milwaukee; never again, 911 has earned all my business in the future!

Our first great experience, was as new homeowners on the hottest day of the year. It was July 3rd, just before the holiday, and the A/C was weak and the outside unit covered in frost. We called 911 heating and air, and they were able to diagnose straight away over the phone. They came out the next day on July 4th to help us out, and we were cool again within the hour. They were kind and courteous, very professional, explaining what they did and why (as I am a curious person).

When we decided to instal a mini-split (ductless system in our upstairs attic conversion), they were the first to call. We were thorough and obtained a couple bids for the job, but 911 again was most courteous, and took time to explain the options without speaking poorly of the competition, and beat the price of their competitors. We had them out for the install, done in a day, and again were impressed.

This man saved us several hundreds of dollars. A different hvac service had misdiagnosed the heat exchanger of our furnace as being damaged and needing to be replaced. Then they immediately wanted to sell us a new furnace. Because we were suspicious, we wanted a second opinion. 911 Heating and Air came to our home on a Sunday during a Packer game. The man took the heat exchanger out and verified that it was, in fact, still quite good. He also gave us further advice about good filter replacement and how to protect ourselves from carbon monoxide poisoning. We were very grateful for their service. We will be calling them the next time we need help.

6 stars if I could... Absolutely amazing company! When I moved into my current apartment, the entire AC system (13 years old) desperately needed an overhaul. I found 911 on Craigslist and decided to make the call. I’m a man of limited means, so I was looking for something within budget, but with the same quality guarantee that other “big companies” have a reputation for. Honestly, the price quote I was given made me think “ok, what’s the catch?” But Alex & Erik performed better than I could ask of ANY of the better known HVAC companies of the area (I.E. Action, Capital, etc). Their commitment to premium quality work, reasonable pricing, sheer efficiency, and excellent customer service are just a few of the many things which stuck with me, and what has made me refer ALL of my friends to them for HVAC service. Recently, my best friend Kyle was stuck without heat on Thanksgiving day and these folks came out to replace his furnace ON A HOLIDAY!!! In and out in less than 4 hours, did a perfect job, and at a price which would still put other companies to shame. Can’t say anything else about them except, if you haven’t used them yet you’ve been making a big mistake. 911 Heating & Air is the ONLY place I will go for my HVAC needs. Thank you for everything, Erik and Alex!

Perfect. Alex and the team fixed our heater and installed a perfect AC system for our house. Would recommend without hesitation.
