Direct answer
How much does AC installation cost in Pasadena in 2026?
It depends on the home: central AC replacement, a heat pump conversion, or ductless mini-splits, plus ductwork condition, electrical-panel capacity, permits, HERS testing, and the SEER2 equipment tier you select. A trustworthy number starts with a home-specific assessment, not a flat rate.
HUS models a planning estimate through the AC Blueprint: sizing, equipment tier, permit scope, and rebate path, before any final proposal.
Common project types:
- Central AC replacement using existing ducts
- Heat pump conversion that replaces AC and furnace together
- Ductless mini-split for an addition, garage, ADU or hot room
- Multi-zone system for two-story or larger homes
What moves the number: ductwork condition, electrical-panel capacity, equipment tier (SEER2), line-set routing, permit and HERS scope, thermostats and zoning, and rebate eligibility. All of it itemized in your Blueprint before any proposal.

Local planning intelligence
Why Pasadena AC is different.
The details that change an AC plan in Pasadena, before anyone talks equipment.
Right-sized for the climate
Pasadena homes need a system matched to local heat load, not a rule-of-thumb tonnage. Manual J sizing is where an accurate plan starts.
Permits, Title 24 & HERS
Permitting, Title 24 compliance and HERS verification are part of every scope, handled inside the install.
Home styles & ductwork
From older homes with aging ducts to two-story layouts with hot upstairs rooms, Pasadena houses each shape the design differently.
Sizing, SEER2 & quiet equipment
Manual J load calculation, SEER2 tier comparison, airflow balancing and low-sound placement.
Pasadena project factors we commonly review:
- Ductwork condition and airflow before equipment selection
- Electrical-panel capacity for higher-efficiency or all-electric systems
- Rooms that run hot or cold and why
- Permit, Title 24 and HERS requirements
- Rebate and financing options that apply to the home
Pasadena takes real San Gabriel Valley heat, and its housing skews historic, Craftsman bungalows, Spanish Colonials and mid-century estates, often with original ducting and tight access. The city is also its own utility and permitting jurisdiction, which changes the rebate and permit path compared with most of LA. Pasadena Water & Power (municipal).

What we install & service
Central AC, heat pumps & ductless, sized to the home.
Central AC replacement
High-efficiency SEER2 condensers with matched indoor coils, right-sized with a Manual J load calculation.
Heat pump conversion
One electric system that replaces AC and furnace together, often the strongest long-term value.
Ductless mini-splits
Room-by-room control for additions, ADUs, garages and hot rooms, with minimal construction.
Ductwork & airflow
Duct sealing, repair or redesign during replacement. That is the difference between rated efficiency and real comfort.
Thermostats & zoning
Zoning and smart controls for larger and multi-level homes.
Permits, Title 24 & HERS
Permitting, Title 24 compliance and third-party HERS verification, handled inside the scope.
Clean installation
Equipment should fit the home, not the other way around.
Placement, line-set routing, sound levels and sight lines are part of the plan. A recent HUS heat pump installation on the Westside, finished the way it should be.
Equipment
HVAC equipment we review before replacement
Before replacing an AC system, HUS reviews the outdoor condenser, indoor coil, furnace or air handler, ductwork and return air, line set, thermostat and zoning, and the electrical disconnect. Homes with rooftop or all-in-one systems may need packaged-unit planning instead of a standard split. A right-sized plan looks at the whole system, not just the outdoor unit.
Central AC vs. heat pump vs. mini-split
| System | Best for | Ductwork | Key benefit |
|---|---|---|---|
| Central AC replacement | Homes with sound ductwork | Uses existing ducts | Familiar, fast like-for-like swap |
| Heat pump conversion | Replacing AC and furnace together | Uses existing or redesigned ducts | One electric system, rebate path |
| Ductless mini-split | Additions, garages, ADUs, hot rooms | No ducts needed | Room-by-room control |
Rebates & financing

Questions Pasadena homeowners ask
Answers, before the site visit.
How much does AC installation or replacement cost in Pasadena?
It depends on system type and size, your ductwork and electrical, and the SEER2 efficiency level you choose. Pasadena's historic homes often need duct and access review, so we give a firm price after a quick assessment rather than a guess. The fastest way to a real number is to start a free estimate.
Do I need a permit to replace my AC in Pasadena?
Yes. Pasadena is its own jurisdiction, so AC changeouts are permitted through the City of Pasadena and must meet California Title 24 energy code, which usually includes HERS testing to verify duct leakage and refrigerant charge. We pull the permit and handle inspection as part of the install.
Does Pasadena Water and Power offer HVAC rebates?
Pasadena is served by Pasadena Water and Power (PWP), a municipal utility that runs its own rebate programs, not SCE's. Qualifying high-efficiency heat pump and HVAC equipment may be eligible. Amounts vary by equipment, documentation and funding and are subject to PWP approval, so they aren't guaranteed. We review eligibility during your estimate.
Can you install AC in a historic Pasadena Craftsman or Spanish Colonial?
Yes. Older Pasadena homes often have undersized or deteriorated ducts, tight attic and crawlspace clearances, and architectural constraints. We review duct routing, equipment placement and access, and a ductless mini-split is frequently the cleanest fit. We confirm the approach during the estimate.
What SEER2 efficiency should I choose for Pasadena heat?
SEER2 is the current cooling efficiency standard. San Gabriel Valley summers are hot, so a higher-SEER2, variable-speed system costs less to run and cools more evenly. We match the rating to your home and budget rather than overselling.
Should I replace my furnace at the same time as my AC?
Often it's worth reviewing together. The furnace, coil, ductwork, refrigerant type and thermostat should match; replacing aging matched components together can improve performance. Or you can electrify with a heat pump for cooling and heating in one system. We lay out both honestly.
