“I own a home built early this year that is under warranty. We’ve been experiencing issues with our smart thermostats once they’re connected to WiFi. They’ve come out three times to replace the thermostat, but the problems persist. I contacted Lennox and informed them that it’s a known issue with the S30 thermostat, which has been discontinued for about a year. These individuals are installing discontinued items in brand-new homes. Despite my insistence that the thermostat needs to be replaced with a non-discontinued one, they keep insisting on coming out to fix it.”

“STAY AWAY!!!!!!!! Developers, save your warranty team the misery and making home owners miserable. We bought a home from dr Horton and l&s installed our hvac system. Our brand new home is covered in mold.”

“Christopher Garrett has helped me a few times within my builders warranty. Excellent all around, will be hiring L&S in the future.”

“My A/C stopped working suddenly on a hot June Saturday night. After trying some basic troubleshooting, I called their “emergency” number. No one ever picked up. Left a voicemail — never got a call back. Called again Sunday as the house was becoming unbearable for my kids and dog. Again, absolutely no answer or return call. Keep in mind I pay these people a yearly maintenance fee for exactly this kind of emergency, so you’d think they’d care. Nope. Finally called Monday during business hours to tell them I’d been calling all weekend with ZERO response. They sent a tech Tuesday, took my $120 diagnostic fee — then radio silence for days. No estimate, no repair timeline. Every time I call, whoever answers says, “Someone will call you back,” and then I hear NOTHING. Almost 3 weeks have passed, and they still haven't fixed my A/C. The one time someone did call me back was to say they’re “waiting on a part,” but that was it — no updates, no follow-up. I even asked what part it was so I could try ordering it myself, and the rep refused to give me that information. What a scam — they take your money just to leave you sweating with no repair, no estimate, and zero transparency. Do yourself a favor and RUN from this company. Total waste of time and money.”

“We've had numerous issues with this company. First, the initial A/C install in our new build was done without a crucial part. This caused a leak and subsequently we had to replace part of the ceiling in our laundry room which is under the unit in our attic. The part they didn't install was allegedly on backorder, but it took them 3 months to fix it with me calling once a week as they never even kept me updated or reached out. Even once they had the part it wasn't until I called that the repair was arranged. That was a while ago and I opted not to say anything but now .. Last Friday night our A/C stopped cooling and it was upwards of 82F inside. Our A/C was installed by L&S so we called them first but as it was after hours we had to call the emergency line. I left a message after it said I would get a call back in an hour.... It's now Tuesday the following week (almost 90 hours after the initial call) and still no callback. Fortunately the other company I called that night (after waiting 2 hours for L&S to call) called me back and fixed our AC the next morning. Don't say you have an emergency line if you're not going to use it. It's too hot in Houston for that. I see other reviews with the same issue so I shouldn't be surprised I guess. Just like they never called me I won't be calling L&S ever again and will steer everyone away.”
