Start with the space.
Then design the system.
Uneven rooms and a system that never quite feels right deserve more than a new equipment label. We look at the home, its heating and cooling needs, and how air moves through it.
- 01 / Capture the geometry
A 3D scan helps document the room shapes and dimensions.
- 02 / Calculate the load
Manual J combines geometry with separately assessed insulation, windows and other inputs.
- 03 / Plan the airflow
Equipment selection, supply and return paths, duct sizes and room airflow work together.

Our 3-Step Rooftop AC Installation Process
Our process for a rooftop unit installation:
- 01
Plan: Site Inspection and Load Calculation
We inspect the site and the roof, run a Manual J load calculation and plan the installation.
- 02
Install: Crane Lift and System Setup
We schedule a crane to lift the unit onto the roof, then set the curb, connect the unit and complete the system setup.
- 03
Verify: System Testing and Performance Check
Once the installation is complete, we test the system and confirm that everything runs properly.
When a Rooftop Unit Replacement Makes More Sense Than Repair
A failing rooftop unit means constant repairs, higher energy use and unexpected downtime. We assess your current equipment and recommend replacement when:
- Repair costs exceed 50% of the price of a new system
- The unit is at the end of its serviceable life, typically 10 to 15 years
Our technicians evaluate the cooling load, the refrigerant type and the condition of the roof to recommend the most cost-effective solution.
Proper Rooftop Unit Sizing
An undersized unit struggles to cool the space at peak demand, and an oversized one wastes energy. We calculate the load based on:
- Exterior factors such as sun exposure and insulation
- Internal gains from people and equipment
- How the space is used through the day
- Code requirements

Rooftop Package Unit Installation in Los Angeles: questions
Do I need a permit for rooftop HVAC installation in Los Angeles?
Yes. In the City of Los Angeles a new or replacement rooftop unit needs a mechanical permit from LADBS and must meet Title 24. We handle the permit, the inspection and the compliance paperwork.
How long does rooftop unit installation take?
It depends on the complexity of the installation. Standard replacement jobs are usually completed in one day. Projects that involve structural reinforcement or new ductwork often take a few business days.
Is a crane required for rooftop AC installation?
In most cases, yes. Rooftop units can weigh hundreds or thousands of pounds, and a crane is the safe way to lift the unit onto the roof.
Can you replace an old rooftop unit with a new one?
Yes. Our rooftop installation service includes removing and replacing old units. Newer units are more efficient and use newer refrigerants.
What size rooftop unit does my building need?
A general rule of thumb is 1 ton of cooling per 500 to 600 square feet, but we size every unit with a load calculation that accounts for windows and sun exposure, ceiling height, occupancy and the local climate.
