Plan ahead for your system's care

Diamond Thermostat memberships combine annual heating and air conditioning tune-ups with system monitoring and member benefits. Choose the level of support that fits your equipment and the way you want to plan for maintenance and repairs.

Both plans are priced per system. Our team can explain thermostat compatibility, enrollment, and the work covered for your specific equipment before you join.

Before you enroll

Let's review the equipment you have

Tell us the equipment type, how many systems serve the property, and whether you have a maintenance or repair concern now. If you have a model number or photo, keep it handy for your conversation with the team.

Ask how the tune-ups are scheduled, how monitoring works with your thermostat, and how each discount applies. We can also explain the transferable-plan and friends-and-family benefits so you know what to expect.

Diamond HVAC is based in Petaluma and serves the North Bay and surrounding service areas. If equipment is not working now, contact us about the problem rather than waiting for a maintenance visit.

What maintenance do both plans include?

Each published plan includes one performance heating tune-up and one performance air conditioning tune-up per year. Ask the team about the checks appropriate for your equipment and how to schedule the visits.

Does 24/7 monitoring mean 24/7 dispatch?

The listed benefit is system monitoring. It does not promise a technician visit at any hour. Contact Diamond HVAC to discuss how monitoring alerts are handled and current service availability.

Can I schedule service without a membership?

Yes. Contact us about an individual repair, maintenance visit, thermostat project, or installation. We can discuss the available options without assuming you want to enroll in a plan.
