They are rude and untimely. I wouldn’t be surprised if they go under in less then a year the way they run their business. I got a outside unit with them last year and it has stopped working twice now and the owner just cursed me out over the phone... now I have to take them to small claims court. Thanks L&M!! My whole family used y’all, but I think we r in the market for someone else, because this was the final straw. Wishing the absolute worst for your business! You don’t deserve to work in this field, especially for yourselves.

Critical: Professionalism
Do not trust this man I saw him chase a car almost cause a wreak and sat in the middle of the street cursing and threatening the person while a line of cars were behind him, if he acts like this in his business van with such road rage he clearly isn’t competent or mature enough to run a business

Critical: Professionalism, Quality, Value
Agree with the responders who cite unprofessionalism and rudeness by the staff. Also poor quality work, unit stopped working again 2 days after they came, called them back wanted to charge me again, when I questioned it, the lady was rude and disrespectful.

Have spent over four weeks trying to get someone to come back out to work on my A/C. They came to work on it and said they would be back in three weeks, never came back. Called after four weeks to get an update and no response. Called again and they said they would check with a technician to schedule a visit, never heard anything. Called back one more time and got a text message saying they would contact me next week to schedule a visit. Again, nothing happened. Highly unreliable.

Read reviews before selecting L &M and my family highly recommended them; unfortunatlely my experience was different. The quality of the work maybe fine, but the customer service experience from the front office was awful - lacked responsiveness, condescending and dismissive of customer concerns. Lisa (mother) should learn from her son - as he apologized for his mis-steps and my overall experience, which I appreciated.

Great customer service, came out on short notice after hours and got my house cool. Had the unit fixed the next day. Office staff was great and called to make sure everything was working. They will be my first call from here on out.

Short notice was able to have same day service. Very professional. The 2 technicians were able to answer any questions I had about the unit. They fix the issue with my heating unit in a very short time. I recommend L & M to anyone looking to have AC/Heating work done.

L&M Air Conditioning is the best company I have ever dealt with, they sold us our AC about 8 years ago and if we ever have any problems they are here asap. Very friendly and professional. I would recommend them(and do) to anyone looking into buying a central AC.
