Fast Affordable Air recently completed an Air Conditioning project in western Las Vegas, near the coordinates 36.1124306, -115.2266833. The work involved a Rheem rooftop packaged HVAC system, its roof connection, condensate drain, and the ductwork that carries conditioned air through the building.
A packaged unit places the main Heating and Cooling parts inside one outdoor cabinet. This includes the compressor, evaporator coil, condenser coil, and blower. The blower is the large fan that pushes cooled or heated air into the ducts. Packaged systems are common on flat-roof buildings because they save indoor space and allow technicians to reach the equipment from the roof.
The pictures show several important parts of the project. The rooftop equipment was opened for inspection and connection work. The roof curb and air passage were sealed, a PVC drain line was installed or corrected, and damaged or disconnected attic ductwork was addressed. These steps help the Rheem system move air where it belongs without wasting cooling above the ceiling.
Inspecting the Rheem Rooftop Packaged Unit
The first and third pictures show the Rheem packaged Air Conditioner positioned on a raised metal base. This base is called a roof curb. It supports the unit and creates a path for supply and return air to move between the equipment and the building.
Supply air is the cooled air sent to the rooms. Return air is warmer indoor air pulled back into the central AC so it can be cooled again. If the openings beneath the unit are loose or poorly sealed, some of that air can escape before reaching the rooms.
The technician inspected the outside cabinet, service panels, roof-curb connection, and nearby lines. The unit needed to sit level and securely on its base. A stable installation protects the cabinet, reduces unwanted vibration, and helps water drain in the correct direction.
Sealing the Roof Curb and Air Transition
The second picture gives a close view inside the air transition below the unit. The metal surfaces and seams were covered with HVAC sealant. This material is often called mastic. Mastic is a thick sealant used to close small gaps in ducts and sheet metal.
This is an important part of the repair. Even a strong Cooling system can struggle if cold air leaks into the roof opening or attic. Sealing the transition helps more conditioned air reach the occupied rooms. It can also reduce the amount of hot, dusty attic air pulled into the return side of the system.
Better sealing may improve comfort by creating stronger airflow at the vents. It can also help the central Air Conditioning equipment reach the thermostat setting without running as long. Shorter or more controlled operating times can reduce avoidable energy use.
Opening the Service Panel for Connection Work
The fourth picture shows the side panel removed from the Rheem unit. Opening this compartment gives the technician access to the electrical controls, blower section, refrigerant components, and other internal parts.
During this stage, the technician can inspect wiring, confirm that connections are tight, look for damaged insulation, and check that the blower area is ready to move air. After the internal work is finished, the access panels must be secured. Loose panels can allow air to leak and may let dust or rain enter the equipment.
The visible Rheem badge identifies the equipment brand. More information about Rheem Heating and Cooling systems is available on the Fast Affordable Air Rheem page.
Installing the Condensate Drain
The fifth picture shows white PVC piping beside the rooftop system. This is part of the condensate drain. Condensate is the water created when warm, humid air passes over the cold evaporator coil. It is similar to the water that forms on the outside of a cold glass.
The drain gives that water a safe path away from the unit. The raised section of pipe helps form the correct drain arrangement for the equipment. A properly installed drain lowers the chance of water collecting inside the cabinet, overflowing near the roof opening, or causing rust and water damage.
The drain also needs to stay open. Dirt and slime can build up inside the pipe over time, which is why drain inspection is an important part of routine AC maintenance.
Repairing the Attic Duct Connection
The final picture shows flexible ductwork and insulation in the attic. One duct connection appears to have become separated or damaged. A disconnected duct can dump cooled air into the attic instead of delivering it to the rooms below.
Flexible duct has an inner air tube, a layer of insulation, and an outside protective covering. The inner tube must be fastened securely to its metal collar. The connection is then sealed and the insulation is pulled back into place. This protects the cold air from the extreme attic heat found in Las Vegas.
Repairing this connection can improve airflow, reduce hot rooms, and prevent the HVAC system from working longer than necessary. It also helps keep loose insulation and attic dust out of the air path.
System Testing and Project Benefits
After the rooftop and attic work, the normal next step is an operational test. The technician runs the central Air Conditioner and checks the thermostat response, blower operation, drainage, airflow, and cabinet panels. Supply and return temperatures may also be compared to confirm that the system is removing heat from the indoor air.
This Rheem project addressed both the equipment and the path that carries air through the building. That matters because a new or repaired Air Conditioning unit cannot provide even comfort when its ducts are leaking or disconnected.
- Sealed transitions help keep cooled air inside the duct system.
- Repaired ductwork helps deliver air to the intended rooms.
- Insulation protects cooled air from attic heat.
- A correctly arranged drain carries condensation away from the unit.
- Secure panels protect the internal HVAC components.
- Improved airflow may reduce unnecessary system operating time and energy use.
