Older ductwork and hotter afternoons on Santa Rosa's east side
The east side of Santa Rosa usually runs warmer on summer afternoons than the west side, which gets more of the cool marine air coming in from the coast. In Rincon Valley that extra heat lands on homes where the air conditioner may be the second or third one the house has had, but the ductwork in the attic is often original.
Duct materials from those decades don't hold up forever. Older flex duct gets brittle, its inner liner tears, and the outer jacket sags until runs are kinked or crushed. Taped joints let go after decades of attic heat.
Duct board loses its facing. Every leak on the supply side dumps cooled air into a hot attic, and every leak on the return side pulls hot, dusty attic air into the system. The result: a new AC that can't keep the far bedrooms cool in the late afternoon, and a PG&E bill that doesn't drop as much as expected after an upgrade.
For Rincon Valley homeowners, the practical point is this: if you're replacing equipment, have the ducts tested at the same time. California's HERS testing will measure duct leakage as part of the AC replacement permit anyway, and sealing or replacing bad ducts during that project costs much less than going back later.
Signs your ducts are holding back your AC
- Rooms at the far end of the house stay several degrees warmer than the rooms near the equipment.
- Airflow at some registers is weak even with a clean filter.
- Dust comes back within days of cleaning, or you see insulation fibers near registers.
- The air conditioner runs constantly on hot afternoons but the house still lags.
- You can see torn, crushed, or disconnected duct runs when you look into the attic.
A duct inspection and leakage test show where the losses are. Sometimes a few disconnected or crushed runs account for most of the problem. Other times the system needs new ductwork.

Smoke and ash after the Glass Fire
The 2020 Glass Fire burned into the Skyhawk area and forced evacuations across Santa Rosa's east side, including Rincon Valley and Oakmont. For homes this close to the wildland edge, ash fall on outdoor coils and smoke getting in through leaky attic returns are real concerns in any fire season.
A media filter cabinet that takes MERV 13 and sealed return ducts make the biggest difference. Our wildfire smoke filtration page covers the details.

Rincon Valley HVAC questions
Should I replace my ducts when I replace my AC?
Test them first. If testing shows heavy leakage or the flex duct is brittle and torn, replacing ducts during the AC project is the most cost-effective time to do it. Ducts in good shape can be sealed and kept.
How can I tell if my ducts are leaking?
Uneven room temperatures, weak airflow at some registers, dust problems, and high bills are all signs. A duct leakage test measures it directly with a calibrated fan that pressurizes the duct system.
Do you serve Oakmont and Skyhawk?
Yes. Both are within Santa Rosa, and we take calls there for repair, maintenance, and installation, plus 24/7 emergency service.
