That growth has pushed contractor demand well above supply - wait times for quality contractors are among the highest in the Mountain West. Costs have risen from well below to right at the national average in recent years, and continue trending upward.

What to Know About the Boise Market
Boise's rapid growth has created a significant contractor shortage - quality licensed contractors are booking 6-12 weeks out for major projects. Get multiple quotes early and expect premium pricing from established contractors who have more work than they can handle. Less-established contractors may be cheaper but verify Idaho Contractor Board licensing before hiring.
The Treasure Valley has a desert climate with hot, dry summers topping 105°F and cold winters with occasional snow. Both AC and heating efficiency matter year-round. Idaho Power offers rebates for heat pumps, efficient central AC, and insulation through their Home Energy Improvement Program - rebates can offset $500-$2,500 of qualifying HVAC project costs.
Wildfire smoke is a seasonal reality in Boise, typically July through September. HVAC air filtration upgrades and tightly sealed windows have become popular renovation additions. Contractors increasingly recommend MERV 13 or higher filters in new HVAC installations, and some homeowners are adding whole-house air purifiers as part of HVAC replacement projects.
