Know when to repair — and when to replace

Not every failing commercial AC system is worth repairing. When a unit is 12–15 years old, has required multiple expensive repairs in recent seasons, or can no longer keep pace with cooling demands even when it's running, replacement is often the more cost-effective decision — both in repair costs avoided and in energy savings from a modern high-efficiency system.

Rock Hard Refrigeration handles commercial AC replacement from start to finish — load calculation and system sizing, equipment selection, removal and disposal of the old unit, crane coordination for RTU replacements, new equipment installation, electrical hookup, refrigerant charging, and full performance verification.

Repair vs. replace — how we help you decide

We don't push replacement when repair makes sense. When we diagnose a commercial AC system, we give you an honest assessment: what the repair costs, what the system's realistic remaining life is, and what the projected energy savings would be from a replacement. The decision is yours — we just make sure it's an informed one.

Signs it may be time to replace your commercial AC system

System age over 12–15 years — commercial RTUs and split systems have a service life of 15–20 years with good maintenance; older systems approaching end-of-life are candidates for replacement before a major failure
Repeated expensive repairs in recent seasons — if you are spending thousands per year keeping an old system running, replacement math often works in your favor within 2–3 years
Can't keep up with cooling demand — a system that runs continuously and still can't maintain setpoint in North Texas summer is either undersized, failing, or both
Rising energy costs without increased usage — degraded efficiency on an aging system adds directly to your utility bill every month
Using phased-out refrigerants — systems still running on R-22 refrigerant face very expensive recharges; replacement with R-410A or R-32 equipment eliminates this ongoing cost
Major component failure on an old system — a compressor failure on a 14-year-old RTU is often the moment when replacement becomes more cost-effective than repair

What the commercial AC replacement process looks like

A commercial AC replacement is a significant project. Here is exactly what to expect when you work with Rock Hard:

Load calculation and system sizing — we calculate your building's actual cooling load rather than matching the old unit's tonnage, which may have been incorrectly sized to begin with
Equipment selection and procurement — we recommend the right system type, efficiency rating, and brand for your facility and budget
Old system removal and disposal — proper refrigerant recovery, removal of the old unit, and disposal in compliance with EPA regulations
Crane coordination for RTU replacements — we manage crane scheduling, rigging, and the full lift process for rooftop replacements
New system installation and connections — placement, refrigerant line installation, electrical hookup, controls setup, and thermostat programming
System startup and performance verification — refrigerant charge verification, airflow testing, temperature differential measurement, and operational walkthrough

Frequently asked questions

Commercial AC replacement — answered

How do I know if my commercial AC system needs replacement or repair?
Key factors pointing toward replacement: system age over 12–15 years, a compressor failure on an older unit (repair cost often approaches replacement cost), ongoing repair costs that are adding up to thousands per year, persistent inability to maintain setpoint in summer heat, or R-22 refrigerant dependency. Rock Hard provides an honest repair-vs-replace assessment when we diagnose your system so you can make an informed decision.

Yes. Rock Hard Refrigeration coordinates and performs crane-assisted rooftop package unit replacements for commercial buildings throughout North Texas. We manage crane scheduling, rigging, the lift, curb placement, all connections, and full system commissioning.
