Bay Area Summer Notes

While our summers are mild compared to many areas, we do get heat events. Being prepared means:

• System ready before first heat wave
• Not competing with everyone else for service during hot spells
• Comfortable home when temperatures spike

Even if you rarely use AC, test it annually to keep it functioning for when you do need it.
