Denver systems need Denver derating

At 5,280 feet, furnace input, blower speed and refrigerant charge all behave differently. We size and commission every system for local conditions instead of sea-level defaults — which is why our installs run quieter and cost less to operate.

  • Manual J load calculations on every replacement
  • Static pressure and airflow verified before we leave
  • Xcel Energy rebate paperwork filed for you
  • Flat-rate pricing approved before work begins

Neighbors say it best

Trusted across the metro

Our furnace quit at 11pm in January. North Peak had a tech at the house in under an hour and heat back on before midnight.
Marisol T. · Wash Park
They walked us through three AC options without a hint of pressure and finished the install in a single day.
Devin R. · Arvada
The duct sealing made a real difference upstairs. Detailed report, fair price, no surprises.
