The South Hill is Spokane’s signature neighborhood. Craftsman bungalows from the 1900s–30s share blocks with mid-century ranches from the 1950s–60s and new construction infill from the last two decades. HVAC requirements vary wildly across these eras — and the right solution depends entirely on which one you own.
Older South Hill homes typically have: original cast-iron boilers (or original 80% AFUE furnaces), undersized fiberglass flex ductwork, no AC at all (or undersized window units), and frequently a single small utility closet for the furnace. Newer construction has builder-grade 95% furnaces with marginal ductwork and 14-SEER AC.

Common South Hill HVAC work
What we typically handle in South Hill
Craftsman-era boiler replacement
Many 1920s–30s South Hill homes still have original cast-iron boilers. We replace with high-efficiency modulating boilers or convert to ductless heat pump systems.
Ductwork redesign
Fiberglass flex ducts in unconditioned attic or basement pull apart at the boots. Full redesign with R-8 trunk lines + mastic sealing.
Add central AC
Many South Hill homes never had AC. We design ductwork + right-sized central AC, or recommend ductless multi-zone where ductwork is impractical.
Wildfire-smoke IAQ packages
Manito and Cannon Hill homes are heavily affected by smoke weeks. MERV-13 retrofit + fresh-air ventilation + IQAir upgrades.
Cold-climate heat pump retrofits
Mitsubishi Hyper-Heating or Daikin Aurora for older homes where ductwork is impractical. Avista rebate + 30% federal tax credit.
Maintenance plans
Bi-annual visits, priority dispatch, 2-year workmanship warranty. $229/year for one system.
South Hill-specific
What makes South Hill HVAC different
South Hill’s housing stock, elevation, and microclimate all change HVAC design and equipment selection.
Many 1920s–30s South Hill homes have knob-and-tube wiring. Heat pumps often need electrical service upgrades (100A → 200A) before install.
Craftsman homes typically have limited attic access. Ductwork redesign often requires basement or chase installation rather than attic runs.
South Hill clay soil shifts seasonally. Older homes often have slab HVAC equipment that needs foundation inspection alongside HVAC work.
Manito and Cannon Hill homes are tree-shaded and stay cooler in summer — sometimes 5–10°F below downtown Spokane on August afternoons.
Historic district overlays may require HVAC equipment screening (landscape buffer). We help with permit applications and equipment placement.
South Hill proximity to hospitals and downtown means stricter noise ordinances in some areas. We use ultra-quiet Mitsubishi compressors.
South Hill questions
South Hill HVAC FAQ
Our South Hill tech typically arrives within 15–20 minutes for emergency calls. Same-day service is the norm.
Three options: (1) Install ductwork in basement/chase + central AC + furnace, (2) Ductless mini-split multi-zone (most common), (3) High-velocity AC system with small-diameter ducts.
Depends on the system. If functioning well and properly maintained, keep it. If 40+ years old and developing leaks, replacement usually wins.
Avista offers $300–$800 on qualifying high-efficiency furnaces and $800–$2,000 on qualifying heat pumps. Federal IRA Section 25C provides 30% back through 2032.
Yes — many of our South Hill customers own homes on the historic register. We’re careful with character-defining features.

Methodology
How we determined this ▾
How we measure average response time
"Response time" is the interval from completed intake call to first technician arrival on site, measured across 1,840 service calls completed in 2024. Emergency (no-heat / no-cool / gas-leak) calls are excluded from the average and tracked separately. Same-day service is available for non-emergency calls placed before 2:00pm.
How we calculate the same-day dispatch rate
A "same-day" call is one where the technician completed on-site work the same calendar day the homeowner placed the request. This excludes cases where the homeowner requested a future date, emergency calls dispatched within 2 hours (counted separately), and instances where permit-required work had to wait for an inspector.
How we sourced our flat-rate pricing ranges
Pricing ranges are aggregated from completed invoices issued by contractors in our referral network across Spokane County between January 2024 and May 2025. Each range represents the 25th–75th percentile of observed final invoice totals for the named work item, after the diagnostic fee. Outlier invoices (under $200 or over $25,000) are excluded. Ranges do not include permit fees, parts taxes, or after-hours surcharges. Your technician writes the actual quote after on-site diagnosis.
