About HVAC Installation & Repair in Boulder

HVAC work covers heating, ventilation, and air conditioning — from furnace and AC replacement to ductwork modification and zoning systems. Regular maintenance extends equipment life, but most units need replacement every 15–20 years.

Typical costs: A new central AC unit installed runs $3,500–$7,500. Furnace replacement is similar. A complete HVAC system (furnace + AC + ductwork) can be $10,000–$20,000+ depending on home size and equipment efficiency rating.

Common projects include:
  • Central AC replacement
  • Furnace or boiler replacement
  • Ductwork installation or modification
  • Mini-split / ductless system installation
  • Thermostat upgrade and zoning

HVAC replacements and new installations typically require mechanical permits. Equipment changes that affect gas lines or electrical circuits may need additional permits.

Frequently Asked Questions

How much does hvac installation & repair cost in Boulder?
Costs depend heavily on system type and home size. A straightforward AC swap on an existing system runs $3,500–$7,500. Switching from forced air to a mini-split system, or adding ductwork, increases cost significantly. Always get 2–3 quotes.
How do I find a reliable hvac installation & repair contractor in Boulder?
HVAC contractors should be licensed and insured. Ask about their experience with your specific system type (forced air, boiler, heat pump, mini-split). Get load calculations — a good contractor sizes the system to your home, not just matches what you had before.
Do I need a permit for hvac installation & repair in Boulder?
Most HVAC installations and replacements require a mechanical permit and inspection. Your contractor should pull the permit — if they suggest skipping it, that's a red flag.
