Our A/C stopped working on a Sunday and due to health issues, we needed to find a service company available on a Sunday. I called MJB and left a message on their emergency voice mail. Within 10 minutes Tom Buck called me to hear my description of the symptoms. He was just finishing an appointment in Wichita and would be on his way to my home on the south end of Derby. He arrived within 30 minutes! From start to finish he was the perfect example of what you could ever hope for in an HVAC tech and a human being. His evaluation of our system inside and out was as thorough as I could ever imagine and once he was done with the repair, our system is running as well or better than ever. Well worth the price for the evaluation, parts, and labor. Thank you again Tom for an awesome experience.

Our AC went out during the hottest days of the year, and they were out next day! We have been jerked around by a shoddy home warranty for years. We finally had a chance to pick our own repair people, and MJB came highly recommended. I can see why! I was impressed with the honesty and speed at which they fixed our AC unit!

Our commercial building had a lightening/electrical strike and damaged our 20 ton AC unit. No one could find us a new unit before the end of September. Imagining going all of August and September with no AC in Kansas and working inside near 100 degree temps is less than thrilling. Dale and the team at MJB called around and saved the day. They had us a new unit 5 weeks earlier than other could promise and I now have happy employees. The unit is amazingly quiet, super cold and so much more energy efficient. Thank you for being our super hero!

We had a new system installed and I was so impressed with how quick they were in come out and install it, in the middle of a hot summer day. They were so friendly & very professional. I had a small problem with a weird sound and they came over immediately and fixed it. Love them!
