What our professional furnace installations typically include:

  • Home assessment: Review of existing equipment, ductwork, gas or electrical service, and venting
  • System selection: Matching furnace type and efficiency to your budget and comfort needs
  • Old equipment removal: Safe disconnect, haul‑away, and responsible disposal of your old unit
  • Precise installation: Leveling, sealing, and connecting all mechanical, gas, and electrical components
  • Startup and testing: Verifying airflow, temperature rise, combustion (if applicable), and controls
