The air handler — the indoor cabinet that houses the evaporator coil, the blower motor and wheel, the filter rack, and the electric heat strips (where present) — is the component in a split HVAC system that gets replaced, upgraded, or serviced independent of the outdoor unit more frequently than most homeowners expect. A condenser replacement under warranty that does not require air handler replacement, an evaporator coil failure on an older air handler that is structurally sound, an upgrade from a single-speed PSC blower to an ECM variable-speed blower for improved efficiency — all of these bring the air handler into scope without necessarily requiring a full system replacement.
We provide air handler replacement, coil replacement, blower motor upgrades, and air handler service on all major brands in the south Salt Lake Valley market. Every air handler installation includes an AHRI-certified system rating verification for any new outdoor-unit/air-handler combination, static pressure commissioning, and a permit through the applicable building department.
Air handler replacement — separate from a full system replacement — is warranted in several specific scenarios:
Air handler selection for a new installation or replacement follows the same ACCA Manual S equipment selection process as full system replacement, with the additional step of AHRI system certification verification:
Primary air handler lines we install for new and replacement applications: Carrier FE4ANF, FV4C, and FX4D series; Trane 4TXCC and 4TXFA series; Lennox CBX32MV and CBX40UHV series; Rheem RHFC and RVHM series; Goodman ARUF and AVPTC series. For ductless mini-split applications: Mitsubishi SEZ (ceiling cassette), MLZ (low-static horizontal), and SLZ (low-static ceiling) series; Daikin FMHQ and FFQ series.
Evaporator coil replacement within an existing air handler cabinet is performed when the coil has failed (refrigerant leak, formicary corrosion, or physical damage) but the air handler cabinet, blower, and associated components are in serviceable condition. The process:
Coil replacement cost runs $900–$1,800 for the coil itself (standard vs corrosion-resistant coil selection affects the upper end), plus $400–$700 in labor for the full replacement procedure. Total installed: $1,300–$2,500 depending on coil specifications and system complexity.
The blower motor in most residential air handlers installed before 2015 is a PSC (permanent split capacitor) single-speed induction motor. PSC motors run at a single fixed speed, consuming the same wattage regardless of whether the system is conditioning a single small zone or the full house. During continuous fan operation — which is recommended during PCAPS inversion events and common on maintenance plans where continuous air filtration is a goal — a PSC blower consumes 400–600 watts continuously.
An ECM (electronically commutated motor) variable-speed blower motor consumes 60–120 watts at typical continuous fan speeds, reducing continuous fan energy cost by 60–75%. At Rocky Mountain Power’s residential rate of approximately $0.10/kWh, a household running the fan continuously during a 21-day inversion season saves approximately $15–$25 in blower energy cost versus a PSC motor. Annualized over the 18–24 red-burn days of a typical Draper inversion season (plus additional fan operation during wildfire smoke events), the ECM blower’s energy cost advantage accumulates meaningfully over its service life.
ECM upgrade feasibility depends on the specific air handler model. Some air handler cabinets can accept a drop-in ECM motor replacement that reuses the existing blower wheel and mounting; others require a motor-and-wheel assembly replacement that needs to match the cabinet geometry. We assess ECM upgrade compatibility at the estimate visit and provide a parts-and-labor quote before proceeding.
