Rooftop unit replacement
The old unit comes off, the new one goes on. Curb adapter, gas, electrical, controls, start-up, and the crane rigged and gone when the lift is done.
Commercial · Industrial · Residential. Houston, Texas
We put it on the roof. We keep it running.
Ferre sets commercial rooftop units with a crane, wires them, starts them up, and comes back when one quits. Warehouses, plants, restaurants, offices, and the houses in between.

What we do
Jobs we handle, start to finish
The six we do most. If yours isn't on the list, call anyway. It's probably one we do.
02
Commercial repair
Somebody has to open the panel and find it. Contactors, capacitors, boards, compressors, refrigerant. We work on what's already up there, whoever put it there.
03
Maintenance plans
Scheduled visits so a part fails on a Tuesday in March instead of a Saturday in August. Coils, belts, filters, amps, refrigerant, written up every time.
04
Industrial and process
Plant floors, make-up air, big tonnage, ducted plenums. Equipment that has to run when the building is at its hottest.
05
Home AC and heating
The condenser in the side yard, the furnace in the attic, and the thermostat that stopped talking to either one.
06
Bigger homes
Quiet, even and dry. Zoning, variable speed and real humidity control for houses where cold enough isn't the standard.

The heavy side
Most AC companies can't get up there
A rooftop unit isn't a big house system. It weighs a couple of tons, it sits on a curb thirty feet up, and getting it there means a lift, a rigging plan and somebody who has done it before. That's the side of this business we live on.
- 01Set with a craneWe handle the lift, the curb adapter and the rig, so the old unit comes off and the new one lands.
- 02Started up rightGas, electrical, controls and airflow checked before anybody leaves the roof.
- 03Built for what you runWarehouse, restaurant, medical suite, plant floor. The load is different, so the equipment is different.
When it's down
It quit. In August.
A dead rooftop unit in a Houston August empties a dining room, spoils product and sends people home. Call the number, say what the building is, what the unit's doing, and what's underneath it. That's enough for us to know what to bring.
- The address and what kind of building it is
- What it's doing, or not doing
- The make and tonnage off the nameplate, if you can reach it. It saves a trip.
Maintenance plans
Stop paying for the same breakdown
Most of the emergency calls we run were avoidable, and the parts that fail give plenty of warning first. A plan is a scheduled visit on your equipment, and a written record of what we found, so the next failure shows up on paper before it shuts you down.
- Coils washed, drains cleared
- Amp draw and refrigerant read
- Belts, filters, contactors and capacitors checked
- Written up every visit, so you can see it coming
Homes and bigger homes
Houses too
Same crews, smaller equipment. Replacements, repairs and the yearly check on the system that has been limping since June. And for the houses where comfort is the whole point, not just cold air: zoning, variable speed and real humidity control.
- Condenser and furnace repair or replacement
- Thermostats, drains, coils and airflow
- Zoning and humidity control for larger houses
Ferre Air Conditioning & Heating
One name. The same two brothers on the phone.
Robert and Freddy Ferreyra. You're not getting a call center, and you're not getting a different crew every time somebody has to come out.
Where we work
Houston, Texas
Cooling most of the year, Gulf humidity that never really lets up, and a summer that runs equipment flat out from May to October. Houston is hard on air conditioning, which is why almost nothing here fails quietly in a mild month. Tell us the address and we'll tell you straight away whether we cover it.
Our work
Real jobs. Real roofs.
Every photo here's a Ferre job. Nothing is stock and nothing is borrowed.
FAQ
Frequently asked questions
Robert and Freddy Ferreyra. The same two on the phone, every time.
Call and describe it in your own words. You don't need to know the terms.
Call 713-397-6030Do you work on commercial rooftop units, or only houses?
Both, and the commercial side is the heavier half of what we do. Packaged rooftop units, crane lifts, curb adapters, controls and start-up, plus the houses. It's the same company either way.
My unit's down right now. What do you need from me?
The address, what kind of building it is, what the unit's doing or not doing, and the make and tonnage off the nameplate if you can get to it. That's usually enough to know what to put on the truck.
Do you work on units you didn't install?
Yes. Most of the equipment we service was put up by somebody else, sometimes years ago. It doesn't change how we work on it.
Should I repair this one or replace it?
It depends what failed and what refrigerant it runs. R-410A is no longer made for new equipment in the United States, and its price has climbed hard since 2025, so keeping an older system alive costs more every year than it used to. Ask for both numbers, the repair and the replacement, before you decide anything.
What does a maintenance plan actually cover?
Scheduled visits on your equipment. Coils washed, drains cleared, belts, filters, contactors and capacitors checked, amp draw and refrigerant read, and a written record of what was found so a problem shows up on paper before it shuts you down.
Do you do industrial work?
Yes. Plant floors, make-up air and large tonnage equipment. Call and describe the process, the space and what has to stay running while we work.
