What's included in our furnace installation in Orange

How our furnace installation in Orange works

01

Manual-J + Manual-S sizing

Whole-home heat-loss calc + equipment selection. We specify what your house actually needs, not what the old furnace was.

02

Install + venting rework

96% AFUE condensing furnace needs fresh intake + exhaust in PVC. We reroute or replace venting as part of the install, not a $800 change-order.

03

Commissioning + rebate paperwork

Burner calibration on an analyzer, blower amp check, airflow verified. Utility + state rebates filed. 10-year parts + labor warranty.

Common furnace installation issues we solve in Orange

Existing venting wrong for 96% AFUE

Condensing furnaces need PVC fresh-air intake + exhaust. We reroute through the rim joist or chase.

Gas line too small

80% to 96% AFUE upgrade may need gas-line rework. We measure meter-to-furnace pipe size and regulator pressure before install.

Return plenum undersized

Variable-speed ECM blowers need more return CFM than multi-speed. We upsize if needed — included in the quote.

Wrong thermostat for new furnace

Two-stage + modulating furnaces need a compatible thermostat. We include the right one in every install quote.

Drain trap freezing in cold snaps

Condensate drain trap in unconditioned space freezes. We route through interior, or heat-trace the exterior run.
