Rheem Systems
Reliable, efficient Rheem air conditioners, heat pumps, and furnaces — our secondary residential line alongside Daikin, installed and serviced by a family-owned, union-trained crew.
Why Rheem?
A residential line we trust — for good reason
Alongside our primary Daikin Comfort Pro lineup, Rheem is residential equipment we install and service across South St. Louis. It's dependable, widely serviceable, and offered in a full range of efficiency tiers — so we can right-size the comfort and the budget for your home.
We also install and service Rheem on light-commercial rooftops. Whatever the building, we size and seal the system properly — because an HVAC system is only as good as the install behind it.
Built to last
Rheem builds rugged, field-proven residential equipment — and as a line we've installed for years, it's equipment our techs know inside and out for the long haul.
A complete residential lineup
Air conditioners, heat pumps, gas furnaces, and air handlers. We match the right Rheem system to your home, comfort goals, and budget — not a one-size-fits-all box.
Efficiency that fits
From dependable single-stage Classic units to inverter-driven Prestige systems north of 20 SEER2, there's a Rheem efficiency tier for every home and every budget.
Quieter, steadier comfort
Two-stage and variable-speed Rheem systems hold temperatures more evenly and run noticeably quieter than the older single-speed equipment most homes still have.
Real installs

Why install with us
The right system, installed the right way
A new system is only as good as the install. Here's what comes with putting Degenhardt Heating and Cooling on the job.
A brand we know inside and out
Rheem is our secondary residential line alongside Daikin. Years of installs mean deep familiarity with the equipment, the parts on the truck, and the install details that make a system last.
Union sheet metal craftsmanship
Local 36 sheet metal training means clean, straight, well-sealed duct connections. A new system only performs as well as the ductwork you bolt it to.
Decades of South St. Louis experience
Family-owned and union-trained, we've installed and serviced HVAC across South St. Louis for decades — residential and light commercial alike.
Honest, holistic estimates
Before we quote a system we check load, airflow, ductwork, and controls — not just the box outside. Free estimates and upfront pricing, every time.
