Rheem builds central air conditioners, heat pumps, gas furnaces and air handlers in a range of efficiency and comfort levels. CASC is a Rheem Pro Partner and installs Rheem systems across Central Arkansas, with a 10-year parts and 2-year labor install warranty and manufacturer registration on every new system.
What does Rheem make for homes?
Rheem makes the main pieces of a central heating and cooling system: outdoor air conditioners and heat pumps, gas furnaces, indoor air handlers and coils, plus thermostats and accessories.
Rheem is a long-established American manufacturer of heating, cooling and water heating equipment. For homes, its HVAC line is sold through contractors and organized into series that step up from simpler single-stage equipment to two-stage and variable-speed models.
The pieces are designed to be matched. An outdoor unit is paired with the right indoor coil or air handler, and that matched system is what the efficiency rating describes.
In a heat pump home, the outdoor heat pump pairs with an indoor air handler that holds the blower and coil. In a gas furnace home, the outdoor air conditioner pairs with an evaporator coil that sits on top of the furnace, and the furnace blower moves air for both seasons. Knowing which setup you have is the first step in comparing replacement options.
How do Rheem's efficiency and comfort levels differ?
Higher tiers usually add more efficient compressors and blowers, quieter operation and steadier temperatures. Entry tiers cover the basics well at a lower upfront cost.
Cooling efficiency is rated in SEER2, heat pump heating in HSPF2 and gas furnace efficiency in AFUE. New Rheem air conditioners and heat pumps use R-454B refrigerant under the federal refrigerant transition.
- Single-stage: runs at full output whenever it runs. Simple and dependable.
- Two-stage: has a lower setting for mild days, which means longer, quieter, more even cycles.
- Variable-speed: adjusts output in small steps for the steadiest temperatures and better moisture removal.
When does a Rheem system make sense for your home?
Rheem is a fit when you're replacing a central system and want a heat pump, a gas furnace or an air conditioner matched to your existing or improved ductwork.
Most Central Arkansas homes choose between a heat pump and a gas furnace for heat, paired with central air for cooling. The right answer depends on whether you have gas service, how the home is built and how you weigh upfront cost against monthly bills.
If you have rooms the ductwork doesn't reach, a Mitsubishi ductless system may be the better tool for that space.
A few questions help you decide whether it's time to replace rather than repair. How old is the system, and does it still use R-410A or an older refrigerant? Has it needed more than one significant repair recently? Are some rooms always too hot, too cold or too humid? Are your energy bills climbing even though your habits haven't changed?
If the answers point toward replacement, the next decision is the comfort level: single-stage, two-stage or variable-speed. Homes with humidity complaints or uneven rooms often notice the most difference from equipment that can run longer, slower cycles.
What goes wrong with any new system, including Rheem?
Most early problems trace back to installation: wrong size, leaky or undersized ducts, incorrect refrigerant charge or a poor match between indoor and outdoor parts.
An oversized air conditioner short cycles, leaving the house cool but clammy. Restrictive ductwork raises static pressure, which makes any blower louder and harder working. These issues don't depend on the brand, which is why we look at the ducts and the load, not just the equipment.
After a new install, a technician should confirm the details that don't show on a spec sheet: static pressure in the ductwork, the temperature difference across the coil, refrigerant charge, a properly pitched condensate drain with a working safety switch, and thermostat settings matched to the equipment. Those checks are what turn good equipment into a system that performs.
How does CASC install Rheem systems?
As a Rheem Pro Partner, we size the system, check the ductwork, install matched equipment, pull required permits and register your equipment with Rheem.
- Manual J load calculation when the home or system has changed, not on every replacement.
- Tiered replacement options so you can compare efficiency and comfort side by side.
- CASC install warranty: 10-year parts and 2-year labor, with optional 5- or 10-year extended labor.
- Manufacturer warranty terms vary by model; we register your equipment and walk you through what applies.

Frequently asked questions
Is Rheem a good fit for Arkansas heat and humidity?
Rheem makes two-stage and variable-speed equipment that runs longer, gentler cycles, which helps with moisture removal. Correct sizing and ductwork matter just as much.
How long is the warranty on a Rheem system?
Manufacturer warranty terms vary by model, and we register your equipment. CASC's own install warranty is 10-year parts and 2-year labor on new HVAC installs.
Do new Rheem systems use a different refrigerant?
Yes. New Rheem air conditioners and heat pumps use R-454B under the federal refrigerant transition away from R-410A.

- Heat pump vs gas furnace in Central Arkansas A heat pump uses electricity to move heat and also cools your home. A gas furnace burns natural gas to make heat and pairs with a separate air conditioner. Both can work well in Central Arkansas. The right choice depends on gas service at your home, your ductwork, your utility rates and how you like your home to feel.
