What Customers Say About Our Thermostat Services in the Bay Area?
Had the plumber Daniel come to my condo today for a clogged toilet. He spent almost two hours snaking with a camera my drain and pulled out a huge clog of tree roots. He knew exactly what he was doing and did a wonderful job. I would recommend this company very much.
Ron K.
Great, reliable, and timely service at a reasonable price. I shopped around quite a bit before landing on CPI. Their rates were competitive, they responded promptly, and their plumber fixed a few issues quickly and without much fuss. I’ll definitely be calling them again the next time we have issues!
Allan Huynh
CPI Service was sent to my home by my condominium association. They agreed to a very early morning appointment and the gentleman arrived exactly on time. He went through the problem very methodically to see where the problem was. Something that no one else could figure out was taken care of in half an hour. I would very definitely recommend them.

Smart Thermostat Repairs & Installations FAQs for the San Francisco Bay Area Customers
How Long Does Thermostat Installation Take?
Most thermostat installations take 30 to 60 minutes, depending on the model and wiring requirements. Smart thermostats with Wi-Fi setup may take slightly longer, but our Bay Area technicians complete the job efficiently.
Where Should a Thermostat Be Installed?
For accurate temperature readings, a thermostat should be placed in a central location about 52 inches above the floor, away from drafts, direct sunlight, and vents. CPI Service ensures proper placement in every Bay Area home.
Do I Need a Better Thermostat for a Larger Home?
Yes, larger properties often benefit from zoned or advanced smart thermostats, which allow separate areas to be controlled independently. This helps maintain even comfort throughout your Bay Area home while reducing wasted energy.
What Is the Average Lifespan of a Thermostat?
A thermostat typically lasts 10 to 15 years, but older units may lose accuracy over time. Upgrading to a programmable or smart thermostat ensures more reliable performance and energy savings.
Who Should I Call to Fix My Thermostat?
It is always best to contact a licensed HVAC technician rather than attempting repairs yourself. CPI Service offers certified, local experts throughout the San Francisco Bay Area to diagnose and fix thermostat issues safely.
How Much Should It Cost to Have a Thermostat Replaced?
In the San Francisco Bay Area, thermostat replacement typically costs $100 to $500, depending on the model, features, and wiring complexity.
