Air District contractor training
Starting Jan. 1, 2027, new Bay Area Air District requirements will change how water heater replacement jobs are done. Gas water heaters that emit nitrogen oxides (NOx) will be phased out, shifting the market toward zero-emission solutions like heat pump water heaters (HPWH).
Get ready for Air District Rule 9-6
The Switch Is On is offering contractor trainings to help you stay ahead of the change, expand your services, and confidently install heat pump water heaters.
