How much does a new HVAC unit cost?

It depends on the size of your home and your preferences. In order to determine exactly what you need, our technicians will come to your home and provide a free estimate for the expected cost of your installation.

Do you charge a diagnostic fee?

Yes, we charge $79 to diagnose any existing equipment that needs to be serviced or repaired.

Do you make appointments or give a service window?

We provide a service window—it’s usually two hours, but on very busy days, it can be as much as four hours. We always confirm appointments the day before, and we’ll call when we’re on our way or if we’re running late. We want our customers to get the best possible service, so our technicians only take one call at a time, which means they don’t have to hurry through an appointment.

Do you offer an annual maintenance service?

Yes. Our annual maintenance contract includes a tune-up for the furnace in the fall and the air conditioner in the spring, and participants never pay fees for service calls.

Can you tell me if my furnace or air conditioner is safe to run or needs to be replaced?

Yes, we’ll come to your home and provide that service at no cost.

Gil Medrano Jr.: All-Weather Man

By James Florence, Diamond Certified Resource Reporter

VACAVILLE — When Gil Medrano Jr.’s first job out of high school didn’t pan out, he didn’t realize it would free him up for a much bigger opportunity. “I had just quit my landscaping job because the business owner couldn’t pay us,” he remembers. “That very same day, I was telling my friend about what happened and he asked me if I was interested in working with him in the HVAC field.
