"LJ Mechanical is the best! Extremely knowledgeable, honest, professional, and gets the job done super fast! They came out and had our AC up and running in no time after us calling. Larry is the owner. Call him!!"
Neena Monet
"We did the concrete & need to have the AC removed & installed. Larry did a great job! He is professional & a great communicator. I’m glad to have Larry to do the job."
Florencia Djoe
"We had Larry replace an old air conditioning and heating unit in our mobile home. Obtaining the permit took longer than we expected, but once obtained he scheduled the installation quickly. His crew was great, and seemed very knowledgeable of everything required. Finished off in less than a day, and cleaned up and re- installed the skirting just like they were never there. Larry assured we met inspection and communicated with the inspector to make sure we met all requirements. Very competitive price and good experience for us. We recommend highly."
Jerry Hohman
"I was referred to contact Larry regarding AC not coming on. Larry was very responsive and when he checked out the unit it was just a relay and capacitor that he found defected. He replaced parts on the spot and unit was up and running within 45 minutes. I can't express how much I appreciate a company like Larry's that is not out to rip you off with unnecessary charges. Very honest and great guy and highly recommend. We also had him out last week to just look over our heater. He found some corrosion on one of the contacts and cleaned it up. Heater working great. Thank you, Larry!"
