Lighthouse Mechanical Llc

Lighthouse Mechanical Llc operates out of Seguin, TX and handles HVAC work for homes in the area. They focus on air conditioning repair and replacement along with heating systems including furnace service and installation. The crew also takes care of heat pumps, indoor air quality improvements, whole home generators, tankless water heaters, and geothermal maintenance. Homeowners in Seguin deal with hot summers and occasional cold snaps that put heavy demands on these systems, so the company keeps trucks ready for both emergency fixes and planned upgrades to keep houses comfortable year round.

Technicians handle jobs like getting an AC unit running again on the first hot day after a maintenance visit by tracking down tricky electrical or component issues that others miss. One crew led by Tyler showed up courteous and worked together to sort out cooling problems fast. Keith has stepped in on tough AC breakdowns and had systems back online without dragging things out. Tim and the rest of the team have replaced HVAC equipment and Rinnai tankless water heaters after long vacations left homes without hot water, making sure everything meets manufacturer standards and runs right from the start.

Customers keep coming back because the work gets done right the first time without extra callbacks, prices stay fair for the scope of repairs or replacements, and the crew shows up when promised while keeping folks updated on what needs fixing. Reviews highlight how the team stays professional even on complex jobs and treats every house like their own. That steady record of solid results on speed, quality, and clear communication builds the kind of trust that lasts for years. DIRT Score 4.65 from 102 reviews on Finds.

“I give Lighthouse mechanical a high five Tyler and his tech worker was excellent he's a team player very courteous and also the owner Tim i give him a high five and the staff also ..so if u need air-conditioner Lighthouse mechanical is your person!!!”

“I've been a happy customer for years, but wouldn't you know it, first hot day I wanted AC it didn't come on. And this was shortly after the tech was out here for a maintenance visit. My new best friend Keith had us up and running after diagnosing and fixing a particularly difficult situation.”

“We came home from a 10 day vacation last week and no hot water. We had a Rinnai tankless gas water heater installed in March of last year. The installer, however, is not a Rinnai service pro. Lighthouse Mechanical is the only Rinnai Pro (in Hampton) listed on the website. I had called a couple other places that were listed but they couldn't come for days. Kathy at Lighthouse was able to send a tech within a couple of hours. When the technician arrived he (Charles) was very kind, warm and knowledgeable. He handled the diagnostics and had parts ordered in less than 30 minutes. He also was able to leave our water heater functional while we wait for parts. I plan to use them for any of pur future HVAC or plumbing needs.”

“Had the absolute BEST experience today!!! The crew was beyond professional went ABOVE and BEYOND my expectations for HVAC and water heater replacement!!! Tim and the WHOLE team are knowledgeable and friendly, I can not thank you enough.”

“We have had great service with our HVAC system installed by Lighthouse Mechanical. We decided to have a whole house generator installed. We chose to have a Kohler brand system. The generator has performed reliably. When it came time for routine maintenance on our HVAC system, the technician also did the maintenance on our generator, providing a short run time of powering the house with the generator. Great service. I heartily recommend Lighthouse Mechanical for everyone wanting or needing HVAC or generator services.”
