How We Calculate HVAC Prices

Our price estimates combine three inputs:

  • BLS Occupational Employment & Wage Statistics: Government labor data from the Bureau of Labor Statistics provides median hourly wages for hvac professionals in your metro area.
  • National Baseline: Starting ranges are our own editorial estimates of typical national project costs, not a survey of prices actually charged, and are not sourced from HomeAdvisor, Angi, Thumbtack or any contractor.
  • Cost of Living Adjustment: We scale the national baseline by your city's cost-of-living index, so local figures are estimates, not observed prices.

Frequently Asked Questions

Should I repair or replace my HVAC system?

If your system is over 10-15 years old and repair costs exceed 50% of replacement, replacement is usually better. Modern systems are 20-40% more efficient.

What's the most expensive HVAC service?

Full system replacement, which costs $3,000-8,000+ depending on your home size and system quality. Regular maintenance prevents costly emergencies.

How often should I get HVAC maintenance?

At least twice yearly - spring before AC season and fall before heating season. Regular maintenance extends system life and saves on emergency calls.

Why are HVAC costs so high in summer?

High demand in peak season means higher labor rates and longer waits. Schedule maintenance in spring or fall for better pricing and faster service.

What's included in an HVAC tune-up?

Typically: filter replacement, refrigerant check, electrical inspection, and system performance testing. Costs $75-200 depending on location.
