Quick answer
Rooftop Unit Replacement in our service area typically runs by tonnage, fuel type, and curb fit. Most single-unit swaps are a one-day job once the unit is on site. We right-size to the building and run it after-hours so you never close.

What a rooftop unit replacement includes
The full scope.
- Repair-or-replace called straight, with the runtime and cost math both ways, no default upsell
- Right-sized replacement verified against the actual building load, not the old nameplate
- Curb adapters fabricated or sourced so a new footprint does not turn into a roofing job
- Crane coordination, roof protection, and the mechanical permit handled end to end
- After-hours and weekend swaps so the storefront, office, or restaurant stays open
- Straight-cool, gas/electric, and A2L heat pump rooftops up to 12.5 tons
- Startup, airflow and static-pressure verification, and economizer setup documented
How the job runs
Diagnose → quote → fix → verify.
02
Size + spec the replacement
We verify the building load instead of copying the old tonnage (most RTUs were oversized). You get a spec matched to the real load and your fuel type, with efficiency to current code.
03
Curb + crane plan
New units rarely match the old curb. We fabricate or source a curb adapter, schedule the crane, and plan roof protection and the lift path so the swap is one clean day.
04
After-hours swap
Most replacements run nights or weekends so your operation never closes. Same flat rate, no after-hours upcharge.
05
Startup + verification
New unit set, charged, and started up, then we verify airflow, static pressure, and economizer operation and document the readings before we hand it back.
Common local issues
Built for our climate.
Repair vs replace, honestly
Past 12 to 15 years, on obsolete refrigerant, or facing a compressor or heat-exchanger failure, replacement usually wins on total cost. We show you both numbers instead of steering you.
The curb is where swaps go sideways
A new unit almost never matches the old roof curb. Without the right curb adapter the job balloons into roofing work. We handle the adapter so it stays a mechanical swap.
Right-sizing the replacement
Most rooftop units were oversized from the start. We verify the actual load so the new unit holds temperature, controls humidity, and does not short-cycle the compressor to an early grave.
Staying open during the swap
Lost business hours cost more than the unit. We schedule after-hours and weekend swaps with no upcharge so your doors stay open the whole time.

You guys were called out to diagnose a missed diagnosis from another company another company in which said that the unit needed to be replaced because the compressor was bad. Your tech came out and was completely professional and incredibly awesome very polite and knowledge worthy.. Not only was the compressor not bad, but it was just simple wiring that had been messed up your tech fix the wiring issues and all is well. I will definitely be using you in the future and recommending you to anybody who needs heating and air conditioning repairs.

Our A/C went out on Wed 08/31at 2:00am, as you know this has been a tremendous heat wave. I called on Thursday, Joseph came out gave me an estimate, ordered the unit and had it installed on Friday. Joseph's technicians worked quickly and efficiently. In my opinion they went above and beyond to get everything installed, keep in mind this is Labor Day weekend. I can't THANK YOU enough. Pricing and financing was amazing as well.

Rooftop Unit Replacement FAQs
Do you do commercial rooftop unit replacement?
Yes. JC Energy Solutions replaces commercial rooftop package units (RTUs) across the High Desert and Inland Empire, including sizing, curb adapters, crane coordination, permits, and after-hours scheduling. Call 760-983-2326.
Should I repair or replace my rooftop unit?
If the unit is past 12 to 15 years, on obsolete refrigerant, or facing a major component failure (compressor, heat exchanger, coil), replacement usually wins on total cost. We give you the repair number and the replacement number side by side before you decide.
Will a new RTU fit my existing roof curb?
Often not exactly. New units rarely match the old footprint, so we fabricate or source a curb adapter. That keeps the swap a mechanical job, not a re-roofing job.
Can you replace our rooftop unit without closing the business?
Yes. We schedule most rooftop replacements for nights or weekends so your operation stays open, with no after-hours upcharge.
What size rooftop units do you handle?
Straight-cool, gas/electric, and A2L heat pump rooftop package units up to 12.5 tons, single units or multiple units on a phased schedule.
How long does a rooftop unit replacement take?
Most single-unit swaps are a one-day job once the new unit and curb adapter are on site. Multi-unit projects are scheduled in phases around your hours.
What areas do you cover?
Across San Bernardino County and Riverside County, dispatched from our Hesperia office. See our commercial HVAC overview.
Rooftop unit failing?
We size it right, handle the crane and permit, and swap it after-hours so you stay open.
