Real words from a North Bay customer. Thank you for trusting us with the work, and for taking the time to tell us how it went.

"Excellent communication from the time of booking until arrival of the technician. Once here, the team was excellent - they could not have been cleaner and provided a better installation and experience than if I had done it myself!"

A clogged filter can drop your AC efficiency by up to 15 percent (U.S. Department of Energy) and put real wear on your system. Change yours every 1 to 3 months in summer. Two minutes, one filter, easy.

Mid-June is the easiest window for a tune-up. Heat hasn't peaked, the calendar is open, and a quick maintenance pass before things get hot is usually the difference between a smooth summer and a noisy one. Same family crew working the North Bay since 1932.

Quick summer setting: 78F when you're home during the day, 85F or off when you're out. Nudging the setpoint up while you're away takes pressure off your system and your cooling bill. Small change, real money over a North Bay summer.
