A local business.
A personal approach.
Diamond HVAC Services Inc. was established in 2022, bringing more than a decade of industry experience to heating and cooling projects across the Bay Area. We are based in Petaluma and work with both homeowners and businesses.
Our work ranges from everyday repairs and maintenance to complete system installations. We also help with the less obvious parts of comfort: ductwork, filtration, wine cooling, and sauna equipment. Whatever brings you to us, the first step is understanding the problem you want to solve.
See a little of our workGood work starts with a clear conversation.
Your concerns come first.
Tell us what changed, which room is uncomfortable, or what you want from a new system. We build the conversation around your property.
Know the next step.
We explain the findings and proposed work so you can understand the scope before making a decision.
Feel comfortable using it.
Ask about controls, filters, and future care. The handoff matters as much as the installation or repair.
Options for a better-fitting system.
As a Mitsubishi Diamond Elite Contractor, we can discuss Mitsubishi Electric equipment for suitable heating and cooling projects. Ductless and heat pump options can be useful when you want more control over particular rooms.
We also offer financing through FTL Finance. Ask our team about current options, eligibility, and the terms available for your project. Equipment warranties and coverage depend on the selected product and applicable requirements.
