Rooftop units

Rooftop Unit (RTU) Service, Repair and Replacement Planning

Packaged rooftop equipment carries most of the cooling load in Las Vegas commercial buildings, and it lives in one of the harshest spots in the valley.

Rocket Air Conditioning diagnoses, repairs and maintains rooftop units and helps plan replacements when a unit has reached the end of a sensible service life.

Diagnostics

What we look for on an RTU call

The symptom in the space rarely names the failure on the roof. Diagnosing properly is what keeps you from paying for the wrong repair.

Cooling that falls behind in the afternoon

Often airflow or condenser related. The unit runs but cannot keep up once outdoor temperatures peak and internal load builds.

Short cycling or repeated lockouts

Controls, safeties or electrical components protecting themselves. Worth diagnosing before it becomes a compressor replacement.

Hot and cold zones in the same space

Distribution, damper or economizer behavior rather than raw capacity. Adding capacity would not fix it.

Rising noise or vibration

Bearings, blower assemblies and mounting hardware. Usually a warning you get weeks before a hard failure.

Repair or replace

Making the call without guessing

There is a point where each repair is buying a shorter and shorter runway. We put the unit's age, the cost of the repair in front of you and what the service history shows side by side, then explain which way we would go and why.

If replacement is the answer, we scope it as a project: what the space needs, how the swap gets staged and what it will cost, so it can go into a capital plan instead of an emergency.

Keeping units on a schedule between now and then is covered under our commercial maintenance agreements.

Questions

Rooftop unit questions

Sustained heat and dust. Condenser coils load up, electrical components run near their limits for months, and a marginal part that survived spring gives out during peak load.
