HVAC Sunnyvale repairs, maintains and installs heating and cooling systems for homes and businesses in Sunnyvale, Santa Clara and Cupertino. Our office is in Sunnyvale, and we have served the area since 2009. Most of our work is AC repair, emergency cooling and heating calls, furnace diagnostics, heat pump questions, ductwork symptoms and indoor air quality planning.
How we work
- Integrity first. Every recommendation is tied to the findings, the repair scope, the warranty situation and the cost factors, and you see all of it before you approve the work.
- Diagnostic discipline. Good HVAC work starts with the symptom, test readings, airflow and electrical checks. A part gets replaced because a reading pointed to it, not because it is a common failure.
- You decide what to fix. You should leave the visit knowing what failed, what can wait and which repair is worth approving.
- Parts that fit the system. Parts are chosen for the brand, model, age and warranty situation of your equipment, and for whether they can still be found. See the brands we service.
- Repair before replace. A failed capacitor, a thermostat, a clogged filter or an airflow problem is ruled out before anyone talks about new equipment.
What to verify before any HVAC work
Whoever you hire, a few questions protect you before you sign off on a job:
- License and insurance. Ask for current details before approving installation, refrigerant, electrical or major replacement work.
- A written scope. A good estimate explains the symptom, the test findings, the recommended repair, what is excluded and what could change the final cost.
- Warranty context. Ask whether the manufacturer’s warranty, parts availability or the system’s age should change the repair-or-replace decision.
What you can count on
- Same-day service is available, and urgent no-cooling and no-heat calls get the earliest opening.
- Phone lines staffed 24/7, with technicians working 8 AM to 8 PM every day.
- EPA-certified technicians for work on refrigerant systems.
- A warranty on repairs covering both parts and labor.
- Independence. We are not affiliated with any equipment manufacturer, so the advice follows the system in your home rather than a product line.

Where to start
If something is wrong right now, go to the page that matches the symptom: AC repair, furnace repair or indoor air quality for smoke, dust and allergies. A yearly check under a maintenance plan keeps small problems from turning into urgent calls, and the full list is on our services page.
