What is Daikin FIT?
A complete Daikin system, built for real homes
Daikin FIT is an inverter-driven outdoor unit that pairs with a matching Daikin furnace or air handler and the Daikin ONE smart thermostat to act as one system. Available as straight cooling or as a full heat pump — both run smoother and quieter than the on/off condensers most homes still have today.
We install FIT for South St. Louis homeowners who want serious efficiency, modern comfort controls, and a manufacturer-backed warranty — without the noise and bulk of older equipment.
Inverter-driven efficiency
The FIT compressor ramps up and down to match the moment instead of slamming on and off. That means steadier temperatures, less energy waste, and a more comfortable home.
Quiet by design
Side-discharge airflow and a sound-engineered cabinet keep the outdoor unit quieter than traditional top-discharge condensers — important on a small St. Louis lot or near a bedroom window.
Compact, low-profile cabinet
The FIT outdoor unit fits tight clearances where a traditional condenser will not. Useful on older South City lots or anywhere side-yard space is limited.
Heat pump or AC configurations
Available as a straight cooling unit or as a full heat pump. Either way, it pairs with a Daikin furnace or air handler — and the Daikin ONE smart thermostat ties it all together.
Real installs
Daikin systems we've installed across South St. Louis
Real Daikin furnace, condenser, and ductless work from our crews — installed and sealed to factory spec by Local 36 union sheet metal technicians.
Why install with us
The right system, installed the right way
A FIT system is only as good as the install. Here's what comes with putting Degenhardt Heating and Cooling on the job.
Daikin Comfort Pro Authorized Dealer
We are a participating independent Daikin Comfort Pro Authorized Dealer — the program required for the homeowner rebate and for full factory-backed warranty terms.
Union sheet metal craftsmanship
Local 36 sheet metal training means clean, straight, well-sealed duct connections. A high-efficiency system will only perform as well as the ducts you bolt it to.
40+ years on St. Louis homes
Family-owned since 1984. We know which neighborhoods have the tight side yards, the older registers, the steam-to-forced-air retrofits — and how to install a modern FIT system into all of them.
Honest, holistic estimates
Before we quote a FIT system we check load, airflow, ductwork, and controls — not just the noisy box outside. Free estimates and upfront pricing, every time.
What a FIT install includes
A complete, factory-matched system
For the rebate and full warranty, Daikin requires every piece work together. Here is what we install on a typical FIT job:
- Daikin FIT outdoor unit (heat pump or straight cooling, sized to your home's load)
- Matching Daikin furnace or air handler — factory-paired to your FIT outdoor unit
- Daikin ONE smart thermostat — controls the system as one and supports remote scheduling
- Inspection of existing ductwork, including duct sealing or modifications as needed
- Refrigerant line set, electrical, and condensate work to code
- Startup, calibration, and walkthrough so you know exactly how the system runs
