Returned to a restaurant in Vallejo CA to make repairs on their Lennox air conditioner. The unit needed its economizer controls replaced and a broken drain line repairs. After completing all quoted work, our technician tested and cycled the unit. No more issues to report, job complete.
Inspected smoke detectors and found them to be tripping causing HVAC units to not work. Issue is below the roof line so need to get alarm company out.
