Honesty is a core principal at Sunvale Heating and Cooling.  You will understand any costs and authorize all work, before we begin.


We will come to your home, business, or commercial property, and diagnose the problem for a flat rate of $89.00. Included in the diagnostic fee is a full System Performance Checklist.  You will have a complete and thorough understanding of how your system is operating and you will be able to make informed decisions about how you want to proceed.  If we are able to complete the repair at the time of your initial visit, we will waive your diagnostic fee.

The Sunvale Flat Rate Diagnostic fee does not change based on the day of the week, or the time of day.

We have fully stocked vehicles capable of completing most repairs on our initial visit.  We also carry a full compliment of Navien tankless water heater parts.
