What Lenders Look At for Plumbing & HVAC Business Loans

Underwriting criteria for plumbing & hvac loans:

Positive signals that improve approval odds: - Master plumber or HVAC license held by owner or key employee - Recurring service contract revenue (maintenance agreements) demonstrating predictable cash flow - DSCR ≥ 1.25x including service truck financing - Diversified customer mix (residential + light commercial + new construction) - Established lead generation (Google reviews, Angi/HomeAdvisor presence, referrals)

Risk factors lenders evaluate: - Licensed technician shortage - revenue capped by available licensed plumbers/HVAC techs - Seasonal HVAC demand (summer cooling, winter heating) creates cash flow swings - Equipment replacement cycle (service trucks, tools) requires ongoing capex - Insurance and bonding costs significant - Refrigerant regulation changes (R-410A phaseout) require ongoing tech retraining

DSCR (Debt Service Coverage Ratio) is the key metric: annual net income ÷ total annual debt service ≥ 1.25x. Some lenders require 1.35x+ for plumbing & hvac businesses due to industry-specific risk factors. Use the DSCR calculator to run your numbers before applying.
