“They did the roof and the ducts at the same time — I didn’t even know that was possible. My house is finally comfortable in summer. Best decision we’ve made.”

FAQ

Real Questions. Straight Answers.

We run a diagnostic before every HVAC quote and record it on video. You see the exact condition of your system before we recommend anything. We quote only what the diagnostic confirms — no padding, no assumptions, no guessing.
Yes, and that’s the point. When the roof deck is already open, it’s the cleanest and least disruptive time to access your ducts — no ceiling cuts, no mess inside. Most homeowners say they wish someone had told them this years ago.
Our application uses a soft pull only — it won’t affect your score. Most homeowners are approved in under 60 seconds. We offer 0% interest for 18 months, 4.99% APR for 12 months, and extended terms up to 120 months. $0 down on qualifying jobs.
As a GAF Master Elite™ certified contractor — fewer than 3% of US roofers qualify — we offer the full GAF System Plus Warranty covering shingles, installation, and workmanship up to 50 years, including sealed duct penetrations when done through the open deck.
29 years in Central California — we don’t disappear after the invoice. Our completion video is your permanent record. If there’s ever a question about what was done, the answer is on camera. Fully licensed, insured, and standing behind every job with our name on it.
