JLM Heating and Air Conditioning

JLM Heating and Cooling just put in my new furnace, and honestly, I can’t believe how excited I am about it! The whole thing was easy, straightforward, and stress free. I actually had Classic Air Care come out first for an inspection, and they told me I needed a new furnace. Their quote was $1,500 higher for the exact same model I ended up getting, which made me feel like they were trying to take advantage of me. Jozo from JLM gave me a lower price, even slightly better than Rhymes. However, I didn't make my decision solely based on price. Jozo's thoroughness and attention to detail is what sets him apart. Even though I only called him requesting a bid for a new furnace, he did his own inspection, took the time to show me photos, and explained exactly what was wrong. That honesty and attention to detail made me feel completely confident about moving forward. If you need any heating work in St. Louis, I’d definitely recommend JLM!

We were so pleased with the team from JLM heating and air conditioning! They helped us get our ac back up and running on one of the hottest days of the summer! We appreciated the timely response and honest feedback about our options. We ended up replacing our ac, furnace, and water heater and everything in our home is so much more comfortable and working very smoothly. Jozo and his team were timely, worked quietly and cleaned everything up nicely. We are thankful for their help and highly recommend them!!!

It was no fun having to have our furnace replaced...but Andrew and John at JLM eased the pain some. Both of them provided excellent customer service and had smiles on there faces everytime I saw them! They arrived exactly when they said they would and kept me informed of their progress. I couldn't be more impressed with their service!

JLM Heating and Air Conditioning is exactly the kind of locally owned business you want to support. The first company I called tried using sketchy pricing tactics and was clearly driven more by private equity than by customer service... as it turns out quite a few STL based HVAC companies have been acquired by PE. JLM was the complete opposite — straightforward, honest, and professional from the start. Scheduling was easy, they arrived on time, and the technician explained everything clearly. The work was excellent, fairly priced, and they left everything spotless. Couldn’t ask for a better experience. Highly recommend!

We were in the market for a furnace and AC before the Summer season, so I received several quotes from local companies. Usually salesmen will reach out and throw around complex terminology or rush you for a special deal - not JLM. They were the 3rd company I received a quote from and I chose them immediately after Jozo came by for the quote. Jozo was great to work with - fast at replies, explained the benefits and differences of our options, and was available to work with our busy schedule. Him and his crew were in and out in a day and we love our new high-efficiency system. Bonus points for helping us install our water heater as well.

Update (21 October 2025): Received our first "full cycle" electric bill since replacing our HVAC. Added picture from the email Ameren sent us. Total electric bill DECREASE has been over $300/month since replacing the HVAC. ***** Our HVAC was old enough to buy its own booze and make bad decisions. We decided it was time for it to move out and move on with its life. How would it ever meet a nice girl and settle down if it stayed living with us? Anyways, Jozo and his team were referred to us by a friend, and I’m so glad they were. He came out, did some tests and evaluated our old system. Then sat down with us, listened to our complaints (electric bill is super high, cold/hot spots in the house, trouble keeping house cool on very hot days), and gave us his recommendation. He gave us the Goldilocks version of estimates (Good, Better, Best) where every option was a good one. He never pressured us to pick one over another, he just explained the benefits of each and let us decide. Financing was available, and was a quick, easy process we completed over the phone. The work we needed done took two days. We had the new AC online the first day, and noticed immediate improvements in temperature and air flow. Our first electric bill dropped by over $100 and that was just for a partial month with the new unit. We’re looking forward to our next bill (never thought I’d say that!) to see what a full month with the unit looks like. The second day of work involved adding additional air return vents to further improve air flow (especially for max capacity days when it’s super hot or super cold), and installing the furnace and humidifier. It was expectedly loud, and I was glad we sent our dogs to a doggie daycare for the day. They cleaned up everything both days so that I’d barely have known they were here! All in all, it was a great experience, and we will be returning to Jozo and his team if we ever need any further work with our heating and cooling.

Thank you, JLM, for QUICKLY coming out and fixing our air and heating needs. The technician who responded was professional, personal, and knowledgeable. We received a custom service that included tips and tricks for future servicing needs, free of charge! Definitely recommend this company!
