Project Overview
BOMING Air Conditioning & Heating recently completed a 3-Ton LENNOX Heat Pump roof unit installation for a property in the Southern California area. The existing rooftop system had reached the end of its reliable service life, leading to inconsistent temperatures and higher energy use. The team removed the old unit and positioned the new LENNOX heat pump on the roof curb, ensuring proper drainage and structural support.
Why a 3-Ton LENNOX Heat Pump Roof Unit
This capacity matches the cooling and heating load of many single-story homes and small commercial buildings common here in the Chino Hills area. LENNOX roof-mounted heat pumps offer durable cabinets designed for outdoor exposure, efficient variable-speed operation, and strong performance in mild winter conditions typical of Southern California. The all-in-one design reduces ductwork modifications and simplifies future service access.
Installation Process
Technicians began by isolating power and recovering refrigerant from the old unit. They inspected the roof curb and flashing, then set the new 3-ton LENNOX model with crane assistance. New high-voltage and low-voltage connections were made, followed by refrigerant line brazing and a full leak test. The system was charged according to manufacturer specifications, and airflow was verified through the existing duct system. Final steps included programming the thermostat and running multiple test cycles.
Results and Homeowner Benefits
The new unit delivers steady temperatures with lower operating noise. Homeowners gain improved energy efficiency, reliable heating during cooler months, and reduced risk of unexpected breakdowns. Proper roof mounting also helps protect the equipment from ground-level debris. For properties needing similar work, contact BOMING Air Conditioning & Heating to discuss options.
