This air conditioning project involved installing two Rheem Heating and Cooling systems at a home in the Las Vegas area. The finished setup includes two outdoor condensing units and two indoor furnace and evaporator coil assemblies located in the attic.
A split HVAC system has equipment in two main places. The outdoor unit releases heat collected from inside the house. The indoor equipment moves air through the home and removes heat and moisture from that air.
Because this home uses two central AC systems, each unit can handle its assigned part of the house. This can provide more even Cooling and keep one system from carrying the entire workload by itself.
Installing the Outdoor Rheem Condensing Units
The first two photos show the completed outdoor portion of the project. Each Rheem condenser was placed on a solid equipment pad beside the home. A condenser is the outdoor part of an Air Conditioner. It contains the compressor, outdoor coil, and fan that help move heat out of the building.
A level base is important because it keeps the equipment steady. It can also reduce unwanted movement and vibration while the fan and compressor are running. Metal brackets were installed at the bottom of the units to help keep them properly positioned.
The outdoor equipment was connected to nearby electrical disconnect boxes. A disconnect is a safety switch that lets an HVAC technician shut off power near the unit before testing or servicing it.
Refrigerant lines also connect each outdoor condenser to its matching indoor coil. Refrigerant is the special fluid that carries heat between the indoor and outdoor equipment. These lines must be properly connected, sealed, and insulated so the central Air Conditioning system can operate correctly.
Installing the Indoor Heating and Cooling Equipment
The remaining photos show the indoor Rheem equipment installed horizontally in the attic. A horizontal installation means the equipment lies on its side instead of standing upright. This setup is common when attic height is limited.
Each indoor assembly includes a furnace section and an evaporator coil section. The furnace provides heat during cooler weather. The evaporator coil provides Cooling by absorbing heat from the air during the summer.
The equipment was supported by metal framing instead of resting loosely on the attic floor. Good support helps keep the cabinets aligned with the ductwork and reduces strain on the attached pipes and connections.
Connecting the Existing Duct System
The attic photos show several insulated flexible ducts connected to the indoor HVAC equipment. Ducts are the large tubes that carry cooled or heated air to rooms throughout the home.
Insulation around the ducts helps keep hot attic air from warming the cooled air before it reaches the living space. Properly connected ductwork can also reduce air leakage. Air leaks make a central Air Conditioner run longer because some of the conditioned air escapes into the attic.
Metal transition pieces were used where needed to connect the new Rheem equipment with the home’s existing air distribution system. A transition is a shaped metal section that joins equipment and ducts of different sizes.
Gas, Electrical, and Control Connections
The photos also show the gas supply connections, control wiring, electrical cables, and equipment panels. These parts allow the furnace, blower motor, thermostat, and outdoor AC unit to work together.
The blower motor is the fan inside the indoor equipment. It pulls air from the house, moves it across the evaporator coil, and sends the conditioned air back through the ducts.
Low-voltage control wires carry signals from the thermostat. For example, when the thermostat asks for Cooling, the indoor blower and outdoor condenser must start in the correct order.
Installing the Condensate Drain System
White PVC drain pipes can be seen beneath and beside the indoor equipment. These pipes carry water away from the evaporator coils.
Water forms because the cold coil removes moisture from warm indoor air. This is called condensation. It is similar to the water that forms on the outside of a cold glass.
The drain piping must have a clear path and the correct slope. Proper drainage helps prevent water from backing up into the equipment or leaking onto the attic floor and ceiling below.
How the Rheem Systems Improve Home Comfort
- More dependable Cooling – The matched indoor and outdoor equipment is designed to operate as one complete system.
- Improved airflow – Correct equipment placement and duct connections help move conditioned air throughout the home.
- Better moisture removal – The evaporator coils cool the air while removing excess indoor humidity.
- Quieter operation – Level outdoor pads and secure indoor supports help limit vibration and movement.
- Possible energy savings – New equipment can use less electricity than older Heating and Cooling equipment that has become worn or inefficient.
- Separate comfort areas – Two systems can serve different sections of the home instead of making one central AC unit handle every room.
Installation Checks Before Startup
Before a new Air Conditioning system is placed into regular use, an HVAC technician checks the electrical connections, thermostat operation, airflow, refrigerant circuit, condensate drains, furnace operation, and outdoor fan.
The technician also checks for unusual noise or vibration and confirms that each indoor system is connected to the correct outdoor unit. These startup checks help find installation problems before the equipment must work through the hottest Las Vegas weather.
