J & L Mechanical Services

J & L Mechanical Services operates as an HVAC outfit based in San Antonio, Texas. The city sees long stretches of intense summer heat that push air conditioning units and ventilation systems hard, while winter cold fronts can demand reliable heating and boiler setups. Homeowners and local buildings often need repairs or replacements to keep indoor conditions steady through those swings. The company sends technicians out for ventilation work, exhaust fan installs, and boiler troubleshooting on both residential and commercial properties where systems break down from constant use or age.

Technicians handle specific tasks such as removing worn exhaust fans and building new frames to fit replacements, especially when working around fire suppression equipment at sites like Bethel Lutheran Church. Gary and Joe managed one of those jobs by knowing the layout and completing the swap without issues. Al responded to a call on a boiler system that had started acting up, adjusted the components, and left it running stronger than before so the property could avoid further downtime. These repairs focus on getting the equipment back online quickly while dealing with the existing setup in place.

Feedback shows strong results on quality when technicians like Al, Gary, and Joe complete exhaust fan and boiler fixes, with customers noting the work held up and improved performance. Speed comes through in how fast they address problems on site, though communication and overall experience take hits from reports of aggressive driving by company vehicles on highways and freeways. Price details stay limited across accounts, but the pattern of solid technical fixes mixed with road complaints shapes the rating. DIRT Score 3.3 from 24 reviews on Finds.

“I wouldn’t hire this company! Their drivers love to tailgate and try to run other drivers off the road. That’s such a great company image!!!”

“Gary & Joe were fantastic. Took out our old exhaust fan and framed in a new one. Very friendly and knew just how they needed to do it. Especially working around the suppression system. Bethel Lutheran Church.”

“van pls 4088 driving on the freeway like a maniac. nearly ran me off the road near Toledo. i’m sure these guys are hard to work with being like that then speeding off in hopes i didn’t get a look at him”

“Called JL because our boiler system was acting up and they sent Al out to fix it. Not only did he fix it but it works even better than before! Thanks to JL and thanks to Al in particular for a job well done, we’ll be using them exclusively moving forward.”

“The foreman of the crew was very demeaning and disparaging of competing HVAC businesses which I found annoying and very unprofessional. The foreman also made crude jokes which were creepy and not funny. The foreman acted like he knew more than anyone but I’m not so sure about that.”
