What Fort Bend County homeowners say about us.

Great service. Came the same day. Fixed the problem immediately . Easy to work with.

Nathan Lazarine did an excellent job diagnosing and repairing my A/C system. He was professional, knowledgeable, and took the time to explain the issue and the repair. Everything is working great now, and I really appreciate his attention to detail and his excellent customer service. I highly recommend him!

They came out and fixed what was broken without pushing an entirely new system. Extremely efficient and professional. We will continue to utilize their services for our home in Sienna.

Wonderful service. . Have called them before and received great service.

Amazing customer service from Nathan Lazarine. My condenser units were not working, just blowing hot air and he guided me to resolved the issue without even coming out. No hassle!

Had a new AC put in my home in September 2025. Excellent service. Nathan is a great guy and will take care of things right away. The only AC company I will use… Thanks.

Nathan and his team are extremely professional and courteous. Service is always responsive and reasonably priced. High-level trust. Would highly recommend.

Nathan attended to our need with professionalism and urgency and had us up and running again in no time at all.

Nathan and his team always ready to help with a very little time between my call and kept my AC units functional and replaced two of them when they finally gave up after over 15 years. I Highly recommend them if you’re looking for honest service

When both AC systems are down at once, don’t rely on your warranty to fix it anytime soon. That’s what happened to me after the recent storm. Thankfully, I found Nathan, who attended to the problem immediately and restore the system ASAP.

Nathan and his team provided excellent service. They were very professional, responsive, and completed the job quickly. I truly appreciate their efficiency and would definitely recommend their company to others.

Nathan did a great job replacing my AC system. Very happy with his team and work.

Excellent service and very quick. We had an issue with our AC unit and the next day they came and sorted it all out.

Quick response and communication! Explains your options clearly and doesn't try to make you get something you don't need.

Adam and Nick were efficient, worked quickly and did a great job on the electrical work. Highly recommend these guys.

Weekend AC issue..if course 🙄. Nathan had had soneobe here diagnosed issue Soon as fan motor was obtainable had repair done asap. Adam and Nick were professional and friendly. Appreciate all!!

Just want to give a big shout-out to Nathan and his crew from Lazarine A/C Heat & Electric! They replaced my evaporator coil and replaced the thermal expansion valve that had a Freon leak - all while saving me nearly $7K from what another company quoted. Highly recommend these guys for honest and reliable work!

I was so relieved when Nathan’s team found the issue with my A/C was just the outside unit motor. They were honest, professional, and didn’t try to upsell me on replacing the whole system. They fixed what was actually broken and had everything running again in 30 minutes. Highly recommend them!

The techs, Adam and Nick, were clean, thorough and quick. Adam answered all of my questions and even had a few suggestions on options for us. The price for the visit and cleaning of our HVAC unit is more than fair and the techs were professional. I will definitely be using Nathan’s again and can’t recommend enough. Thanks!

Sending out a big Kudos to the best A/C repair team our area. I texted him Saturday and was ready to send his team out even though it wasn’t an urgent need. They came in timely today (Monday) and got the job done to get our A/C back in good working order. God bless them!

I highly recommend Nathan Lazarine AC and Electrical. The service was exceptional. He came out quickly as promised and fixed our AC for a fair and reasonable price. He definitely earned us as a client going forward. Thanks Nathan!

Used Lazarene once again (3 years ago, and this time the other unit). Replaced an old evaporator coil which was the actual problem. Instead of starting the day at 73 degrees and ending up at 77 by 2p.m., we were sitting at 72 degrees at 4:55p.m. about 5 hours after they left. Reliable every time! And my dogs apparently like them too.

Incredibly prompt service. Reasonably priced. Great neighborhood business!

I’ve used Nathan Lazarine’s HVAC service several times and have always been satisfied with his communication and work. His team responds quickly and provide quality service for Sienna. Highly recommend.

Great service!

These guys were great. They got me scheduled and serviced asap. Adam came out and didn't rest until he found the problem. These guys really knew their stuff and didn't inflate their quotes. We will call then back again, the last time was 7 years ago and the service is still great. They even installed a new WiFi thermostat for us while they were here. They were really accommodating.

I recently had my entire AC unit replaced by Nathan Lazarine AC Heat and Electric and I couldn’t be more pleased with their service! They were quick, professional, knowledgeable, and incredibly efficient. The installation was seamless and when they were done you couldn’t tell they had even been here working. I highly recommend Nathan and his team! True professionals!!

We have been consistently pleased with the HVAC and electrical maintenance and repairs performed by Nathan’s team. They helped us remediate multiple issues in the deficient electrical system and sub par components installed by the builder. The owner is very involved and ensures the work is complete to the homeowners satisfaction. We strongly recommend Nathan Lazarine A/C heat and electric.

It was easy to schedule an appointment, Nathan explained everything he was planning to do and further explained all of the work as he completed it. He was highly recommended by several neighbors.

Nathan was able to promptly evaluate our HVAC issue with not cooling the upstairs, pinpointed the problem and replaced our capacitor immediately. Recommend!

Nathan Lazarine A/C Heat & Electric to the rescue again! We've been with his team for years and they always help us out! Had an issue with our upstairs AC unit and they came out the next day to look at it. Thankfully nothing too serious but they diagnosed and fixed that day. Fair pricing...Great guys!!! Highly recommend!

And once again, they show up and they take care of the problem. i think I've bee a client for 20+ years with the same top-notch service. Thanks Nathan!

Awesome service. Quick response to my call for service. The technicians answered my questions before I even asked.

AC quit working overnight. Texted Nathan this morning and he had a crew out in about an hour. The guys determined the issue, found a fix and got it taken care of quickly and at no cost to me as it was a faulty part from the manufacturer. Highly recommend Nathan and his guys.

Nathan was quick, responsive & efficient. Very knowledgeable and friendly. Great company to do business with.

Great work as usual. I called them late on Wednesday and they were able to get us in the next day. Open communication and not pushing services. We are limping a total AC replacement along for another summer and they came thru as usual.

Quick Service, very reliable and pleasant to work with. Found our new heating cooling people!

We’ve called on Nathan Lazarine Heating, A/C & Electrical more than once—and especially in tight situations, like during the last hurricane. Nathan is always on the spot, dependable, and honest to the core. What I respect most is that he gives it to you straight. No fluff, no false promises—just fair pricing, professional service, and the truth, even if it’s not what you want to hear. In an emergency, you won’t get a BS “we’ll be there in an hour” if that’s not realistic. His team is always professional, and the company reflects the strength and integrity of its leader. Highly recommend

We’ve called Nathan and his team to help with our AC a few times over the past 10 years. We have always received great service and good advice on different options for the repair.

Not my first time reaching out to, and using, Nathan Lazarine A/C Heat & Electric. Always great service, and makes an effort to assist at the earliest convenience to the customer. Had an issue with our A/C after a storm, and leaving town the next day. Nathan came out quickly after my call for help, and got us squared away so that we didn't have to worry about no air circulation in the hot summer heat while we were away. I would certainly recommend his company if you're in need of A/C repair. Dependable and responsive.

Nathan and his team are the best!

Nathan and his team did a great job diagnosing the “real” problem my AC was having (two others had misdiagnosed the issue and quoted me high repair cost) saving me at least $2k. Great job and good folks to work with.

Nathan and his team are the best! I called Thursday night because one of our AC wasn’t working in the main part of the house. He came Friday morning and diagnose the problem. It was the motor to our blower in the attic. On his own, he looked it up and saw that we were under warranty for another four months. I just got to Lenox to pick it up. They came as soon as possible and fixed it quickly. I should also mention that he came to my house, but I was out and he Waited in his car until I got home.

Always ready and available when we need him. Fast and reliable work. He also has a great work crew. 👍🏽👍🏽

He did what he said he was going to do and my ac works great now.

Nathan arrived early and completed my job promptly! He’s always pleasant and lets you know what the problem is and the cost before he does the work. Glad he’s in the area!

Nathan Lazarine is our go-to AC/Heating company! Fast communication, trusted and competent service.

Excellent service!! Thoroughly explained the work was done. Very impressed.

We have used Nathan and his team over the years and they continue to provide top notch service. Today he was here within minutes to help unclog 2 drain lines. Thank you for your help!

Called Nathan Nazarene A/C because my A/C system was not keeping my house cool. This company obviously gave my service call a very high priority because they sent one of their technicians to address the problem to my A/C within 24 hours. The work was completed to my satisfaction and in a very timely and professional manner.

Prompt and friendly service. Nathan and his crew took the time to help get my AC up and running after it turned off in the middle of the night and I couldn't get it back up and running. They took the time to explain what maintenance I could do to minimize the problem and walked me through each of the steps they did to diagnose and fix the problem. I would highly recommend them if you want someone local, with fair prices, and really knows what they're doing.

Responsive, transparent, and no upselling! He was able to diagnose our AC’s issue and provided solution options that we can understand. Best was I contacted him yesterday, was in our home today as promised, and already has our AC running cold before he even left.

If you’re looking for fast, reliable AC service without breaking the bank, this is your guy. He showed up on time, diagnosed the issue quickly, and had my AC blowing cold air again in no time. Super professional, honest pricing, and no upselling just straightforward, quality work. Definitely keeping his number saved for next time!

Great communication, on time, and great work. You can tell that this team has the customers best interests in mind.

Love these guys! Hard working crew. They’ve come out to my house a few times for AC issues and, most recently, electrical issues. They have diagnosed my problems within 5 mins every time. One truly notable experience- we have an AC unit on its last leg upstairs. Nathan could have told us we needed to buy a new unit, and we would have been none the wiser. But instead he replaced our compressor- A HUGE difference in price. You won’t find more honest guys, and I doubt you can find better prices. Always reasonable, always honest.

We had a great experience with their service. They were able to diagnose a what seemed like a very tricky problem with our damper system. Problem was diagnosed and resolved within an hour and for a very fair price. I also love that their internal policy is to prioritize customers with zero A/C over any other calls. This meant it took a few days for them to come out, but I did not mind as I know that they care about how best to serve the community.

Nathan went out of his way to alter his daily schedule to get my AC unit back running! He was able to diagnose and fix the issue quickly! Highly recommend!
