Lantz’s combination of speed, fairness, and genuine customer care is why they continue to earn my loyalty! Aug 15, 2025

I am consistently impressed with Lantz's Home Services! My AC went out yesterday afternoon, and when I woke up this morning to find it still not cooling, I submitted a service request online at 6 AM (I love their user-friendly platform online!). Within an hour, I received a call to confirm my needs, and by 9 AM, Darren was at my door. Within minutes, he identified the problem and had it fixed just as quickly. Darren was fantastic! Personable, professional, and easy to talk to (just like everyone I’ve met from Lantz). Their pricing is incredibly fair, and I especially appreciated that Darren treated me with respect and as an equal. Unfortunately, it’s not uncommon for men to talk down to women in these situations, but Darren explained everything clearly and professionally without a hint of talking down to me. Lantz’s combination of speed, fairness, and genuine customer care is why they continue to earn my loyalty! Thank you from a now less sweaty customer.... !

You’ll be in great hands, you’ll get top-notch service from start to finish! Aug 12, 2025

Lantz is an excellent company, and Darren T.—who works for Lantz—was fantastic! Darren came out to check our AC and was prompt, professional, and incredibly thorough. He took the time to explain what he was doing and made sure everything was running perfectly before he left. It’s rare to find someone who combines skill, honesty, and genuine care for their customers, but Darren truly delivers all three. I would highly recommend Lantz and Darren T. to anyone needing AC service—you’ll be in great hands, you’ll get top-notch service from start to finish! We also had some plumbing work done, and again, the service was outstanding. Again I must state, I highly recommend Lantz—wouldn’t have anyone else service my home for A/C, plumbing, and/or electrical needs!

Lantz did a quick turnaround Aug 7, 2025

We had a leak in our evaporator coil. Lantz did a quick turnaround and had our AC working before the coolant ran out. Big thanks to Derek and his crew.

They exceeded all my expectations! Apr 18, 2025

I commend Derek J., the technician, for his excellent job fixing my air conditioner. He was very friendly, professional, and knowledgeable. After troubleshooting the unit, he thoroughly explained the issue and was able to repair it on the spot. His skill and attention to detail were impressive. I highly recommend Lantz Lakeside Plumbing and AC Services to family, friends, and everyone. They exceeded all my expectations! Keep up the excellent work! New Lifetime Member, Cleo

He was able to get our AC back on that day. Apr 17, 2025

Our AC failed to come on in mid-April with company heading our way. Lantz's Plumbing sent out Derek J. the same day we called, and he was able to get our AC back on that day. Thanks!

Darren Is 10/10 Mar 18, 2025

I have had 3 great experiences working with this crew! Darren is 10/10. I really enjoyed working with him while he fixed my expansion valve and helped my home get its A/C back before summer comes. Darren was very personable, knowledgeable, and kind! I will continue working with Lantz for any AC or plumbing issues and I appreciate the help!

Kalyn Calhoun

That’s great, fast service! Jan 19, 2025

Our AC broke while we were on vacation, so we walked into a very hot house! I called Lantz the next morning. Eduardo D. was here at 10 a.m. and the AC motor was replaced and we had a cool house again by 3 p.m.! That’s great, fast service! We are very satisfied with him and this company. Have done business with them before for emergency plumbing and they were there the same day!

He is by far the most reliable and professional Nov 6, 2024

Greg and companion came over to fix my AC unit. As usual, they did an awesome job. I used Greg’s service before and he is by far the most reliable and professional person I have ever had working on my units and for a good price. He is a great guy and great to work with! Would recommend Lantz to everyone who needs AC work done!

He did a great job and fixed my issue quickly Oct 29, 2024

I called Lantz for an issue I was having with my AC. They said they could come out the same day and were very punctual. Steve was my tech; he was knowledgeable, honest, and very communicative. He did a great job and fixed my issue quickly, checking my entire system before he left to make sure I was good for the coming winter. Payment was quick and easy at a fair price. I’ll be using Lantz from now on.

I highly recommend them - 100% Integrity. Oct 28, 2024

***** Five stars for Lantz's Lakeside P & A/C. They are super quick to come to your aid. First, my sewer pump electrical contactor was out; the guy came that day and checked it out and got it to pump. Second, they came out the same day for my A/C, which froze on the old unit, and got it working again. I highly recommend them - 100% integrity.

Lantz’s is fantastic to work with! Oct 11, 2024

Very friendly, helpful, professional, and thorough – Eduardo explained everything and got our AC back in working shape. We HIGHLY recommend Lantz’s!! Update: we had a compressor die and Darren was awesome. He came out within 45 minutes of us calling in, he diagnosed the problem, researched our warranty possibilities, gave us options, and got us fixed up really quickly. He was super friendly, knowledgeable, and helpful at all times. Lantz’s is fantastic to work with!

Extremely satisfied with the level of quality & competency. Oct 8, 2024

We called Lantz's to troubleshoot an A/C issue as it was not cooling to the desired temperature. By request, Steve came out since he was familiar with our HVAC system. He identified that the refrigerant level was low. When I told him that the refrigerant was refilled only about a year ago, he had the professional sense to check the evaporator coils for leaks. His hunch was correct. He demonstrated how his tool was detecting moisture. We gave him the go-ahead to replace it. He made sure to cover our hardwood floor. He kept me informed throughout the entire process. He even showed me the 'leaking' coil. The visible signs of 'wear & tear' validated the decision to replace the part. Prior to completing the job, he did thorough tests to ensure the HVAC system was working properly. He even did us a solid by taping an exposed area in the air handler. Highly recommend Lantz's & Steve for A/C maintenance & repairs. Extremely satisfied with the level of quality & competency.

They were genuinely concerned about my family. Aug 22, 2024

I wanted to thank Lantz’s Plumbing for the great work and employees that work there. I want to thank Darren and Josh who came out to assist my family with an AC problem. They were genuinely concerned about my family being at home with no AC. Lance is lucky to have you both. Keep up the great work. For Lago Vista, you need Lantz’s Plumbing.

Lantz's Plumbing is top quality. Aug 9, 2024

Lantz's Plumbing is top quality. They explained our A/C unit on time and at a fair price. We will be using them many times in the future.

Everything was fixed in less than 24 hours. Jul 17, 2024

This is the second time in about 7 weeks we've had AC issues. The first time we called several places and none of them could come same day even though their websites advertise 24/7 service. We called Lantz's and they were at our house in less than 30 minutes. So when our AC wasn't cooling this week (a different issue from last time) we didn't waste time calling anyone else and called Lantz's. It was after hours, but he still showed up within 30 minutes of our call. He did what he could to help us get through the night and first thing the next morning he was calling with an update on the part and when he could be back to install. He just finished installation and all is well. Everything was fixed in less than 24 hours. Both times Darren has come out and he's been very nice, professional, and super helpful with information. We plan to sign up for their annual maintenance service because they have been a great company to work with and they actually do what they say they are going to do and get it done.

They Did Not Disappoint Jun 20, 2024

Professional, courteous, responsive, and hardworking. Everything from dispatch, assessment to completion of our AC repair was done well. Our real estate agent who grew up in Lago recommended Lantz’s, and they did not disappoint.

Felix Barnhart

Incredibly responsive, professional, and just great people Jun 7, 2024

Incredibly responsive, professional, and just great people... had my broken A/C running within a couple of hours of my call. I will definitely be using them again, thank you!

Steve had it up and running by noon May 28, 2024

Yesterday our A/C broke down during the night so we called them as soon as they opened. Their tech was out on other calls but was informed it would be after 1 p.m. Steve, their tech, showed up around 11:30 and had it up and running by noon (he had the parts needed in his truck). Steve was very good at explaining what was wrong and the price was very reasonable.

Connie Gonzalez

Lantz’s AC is the best. May 19, 2024

Lantz’s AC is the best. I had to call several local companies; they were all closed on the weekends. Steve fixed my AC in a timely manner. He also rerouted some wires and vacuumed all the water.

C Barrera

Got me cooling again in a hurry. May 16, 2024

Hot house and one of the hottest days of the year so far. A/C system just outside warranty period. Steve took the time to explain my system to me. Got me cooling again in a hurry. Made some great future recommendations for my system as well! Hot house call Lantz!

Travis Carfer

Great service and great experience!! Apr 2, 2024

I currently used Lantz for the apartment complex that I managed and let me tell you. I got notified that my tech was coming with ample time to prepare! Then Darren came in and introduced himself and listened to me ramble about my A/C woes (poor thing). He was attentive and informative and reassuring. He went and checked out the system and took videos and pictures and explained everything very thoroughly! Great service and great experience!!
