Commercial Rooftop Unit Service & Monitoring

We watch your rooftop units so you don't have to. Cloud-based monitoring, preventive maintenance, and fast repairs for commercial properties across the Tri-Valley and East Bay.

The Problem

RTUs Fail Silently. You Find Out When a Tenant Calls.

Rooftop units sit out of sight — and out of mind. By the time someone complains about the heat or a strange noise, the damage is already done. Emergency repairs cost 2–3x more than preventive fixes, and every hour of downtime is lost revenue or an angry tenant.

Failures go unnoticed until tenants or employees complain

No visibility into unit health — you're flying blind
How It Works

24/7 Cloud Monitoring for Your Rooftop Units

We install sensors, stream data to the cloud, and alert you before small issues become expensive emergencies.

Step 1

We Install Sensors

Small IoT sensors are mounted on each rooftop unit to track temperature, pressure, runtime, and electrical performance — no disruption to your tenants or operations.

Step 2

Data Streams to the Cloud

Your RTU data is securely transmitted to a cloud dashboard 24/7. We monitor trends, flag anomalies, and track efficiency — so problems get caught early.

Step 3

You Get Alerted First

When something goes wrong — or is about to — you get a notification before a tenant calls to complain. View your dashboard from any device, anytime.

A rooftop unit is a self-contained HVAC system mounted on a commercial building's roof. It handles both heating and cooling and is common in strip malls, office buildings, and light industrial spaces.
How does smart monitoring work for RTUs?
We install IoT sensors on your rooftop units that stream data to a cloud dashboard 24/7. You get alerts when something is wrong — before it becomes an emergency. We also monitor efficiency trends so we can catch degradation early.
What's included in a free rooftop assessment?
We inspect your RTUs, check refrigerant levels, electrical connections, filters, and overall unit health. You get a written report with findings and recommendations — no obligation.
How much does RTU monitoring cost?
Monitoring starts at $30–60 per unit per month. Bundled service plans that include preventive maintenance visits start at $80/unit/month. We'll build a custom quote based on the number of units and your needs.
