Ductwork & Ventilation

Leaky, undersized, or poorly designed duct systems waste up to 30% of the energy you pay for — and deliver uneven temperatures room to room. We inspect, seal, repair, and when necessary redesign duct systems for maximum delivery efficiency and balanced comfort throughout the home.

  • Duct leakage testing and pressure diagnostics
  • Aeroseal duct sealing — seals from the inside out
  • Full duct replacement and re-routing for remodeled spaces
  • Attic and crawlspace duct insulation for heat loss prevention
  • Zoning system installation for multi-level temperature control

  • Nest, Ecobee, Honeywell T6/T9/T10, and Emerson installation
  • Wi-Fi configuration and app setup for remote control
  • Multi-zone thermostat systems for larger homes
  • Smart home integration: Google Home, Amazon Alexa, Apple HomeKit

Service Questions

For emergency calls, our average response time in Terre Haute is under 2 hours. We dispatch the nearest available technician with a fully stocked truck so most issues are resolved in a single visit.
The general rule: if repair cost exceeds 50% of a new system's cost and the unit is over 10 years old, replacement is usually more economical long-term. Our technicians will give you an honest recommendation based on your specific system's condition — we don't push replacements to drive revenue.
Our primary focus is residential HVAC for Terre Haute homeowners. We also service light commercial properties under 10,000 sq ft. For larger commercial needs, we can recommend specialized commercial HVAC contractors in the area.
All labor is warranted for one year from date of service. New equipment installations carry the manufacturer's standard warranty (typically 5–10 years on parts depending on brand and registration). Extended warranty options are available at the time of installation.
