Featured Work

“Our distillery was in shut down mode because of a sudden outage of our instrument communication. Without previous exposure to our system, Paul was able to isolate and solve the issue in just an hour! Paul replaced the burned out parts and had running in the afternoon. We can’t thank him enough. Larkin is our go to company with everything controls related!

“Our air conditioner was not able to keep up with the summer heat. The company that installed it was unable to offer any solutions. Paul was able to get the house significantly cooler than it was before at a very reasonable price, and offered potential options should the initial repair not prove sufficient. So far it has, and I’m very happy with his services.”

“I first got a quote from Best Buy for my small office project. Paul with Larkin Control gave me a quote for half the cost with higher quality components. Paul had the entire project done in one day (Best Buy told me two days), did not leave a single speck of dust and did a phenomenal job. I highly recommend Larkin Controls!”
