Local RTU Installation & Repair Expertise

In San José, commercial buildings depend on reliable rooftop units to maintain comfortable indoor temperatures year-round.

How We Work

We follow a clear, methodical approach to every RTU project. From diagnosis to installation, you'll know what happens at each stage.

Our Process: From Assessment to Handoff

Every RTU project begins with a thorough assessment. We inspect your existing system, test components, and identify what needs repair or replacement. San José buildings face unique cooling demands due to summer heat, so proper sizing and placement are critical to performance.

Diagnose & Assess

We inspect coils, refrigerant levels, electrical circuits, and structural integrity. Testing tells us whether repair is feasible or replacement is the better choice.

Plan & Prepare

We create a detailed scope of work, confirm code compliance, and schedule service around your operations. Site preparation includes safety measures and equipment staging on the roof.

Execute & Install

We remove the old unit safely, install the new RTU per manufacturer specs, connect ductwork, and wire electrical and control systems. All work follows San José building codes.

Test & Commission

We run full system tests, verify airflow and temperature performance, calibrate controls, and train your staff on operation and maintenance practices.

You'll always know what's happening next—and when.

RTU Installation for New Systems

Installing a rooftop unit requires precise sizing, structural engineering, and compliance with San José building codes. We select the right capacity for your space, ensure proper roof support, and integrate the system with your existing ductwork or new installations.

New installations begin with a load calculation to confirm unit size. We verify roof condition, install vibration isolators and roof curbs to prevent leaks, and connect all mechanical and electrical lines to code.

Economizer controls are configured to bring in outside air during mild weather, cutting cooling energy use. We ensure your thermostat integrates smoothly with the RTU for optimal comfort.

RTU Repair & Maintenance

Most RTU problems can be caught early with routine maintenance. Dirty coils, refrigerant leaks, and worn belts are common issues affecting San José buildings. We diagnose and repair these problems before they force a shutdown.

Repair scope includes coil cleaning, refrigerant recharge, contactor replacement, and electrical circuit testing. We inspect dampers, filters, and fan bearings to prevent secondary failures.

Preventive maintenance plans keep energy bills down and extend RTU life. Quarterly coil cleaning, annual belt inspection, and regular filter changes are essential for buildings in Evergreen, South San José, and other neighborhoods with significant summer cooling demand.

Routine maintenance includes coil inspection and cleaning to maintain efficiency and prevent heat rejection problems.

RTU Replacement & Upgrades

When repair costs mount or a unit fails, replacement becomes the smarter choice. Newer RTU models offer higher efficiency ratings, lower operating costs, and better controls. We manage the entire removal, installation, and commissioning process.

Most RTUs last 15–20 years. Beyond that, parts become scarce and repair costs climb. New models recover their cost through energy savings and fewer service calls over their lifespan.

Upgrading to a high-efficiency unit may qualify your San José building for utility rebates. We handle paperwork and ensure your system meets current refrigerant and efficiency regulations.

Why It Matters

Rooftop units are hidden from view but critical to your building's operation and bottom line.

Energy Efficiency & Cost Control

A neglected RTU loses efficiency rapidly. Dirty coils force the compressor to work harder, spiking energy use. In San José's warm months, even a 10% drop in RTU efficiency can add hundreds to monthly cooling bills. Preventive maintenance and timely replacement protect your operating budget.

Newer high-efficiency RTU models can cut energy consumption by 20–40% compared to aging units, reducing annual cooling and heating costs significantly.

Reliability & Business Continuity

An RTU breakdown disrupts your tenants, customers, and operations. Uncomfortable indoor temperatures drive people away. Our maintenance programs catch problems before they force an emergency repair. Scheduled service during mild seasons keeps your building safe from summer or winter shutdowns.

Frequently Asked Questions

Common questions about RTU installation and repair in San José.

What is an RTU and why is it used in San José commercial buildings?

An RTU is a self-contained heating and cooling system installed on a rooftop. It supplies conditioned air throughout your building via ductwork. RTUs are popular in San José because they save indoor floor space, are relatively easy to maintain, and can be sized to match your building's cooling and heating demands.

How often should I have my RTU serviced?

We recommend at least two service visits per year: one before the cooling season and one before the heating season. If your RTU is exposed to heavy dust, salt air, or industrial pollution, quarterly maintenance is a better investment to keep it running efficiently.

When should I replace an RTU instead of repairing it?

If your RTU is over 15 years old and repair costs are climbing, replacement usually makes economic sense. We compare repair quotes to replacement costs and help you decide based on your building's long-term needs and energy goals.

Does San José require permits for RTU installation?

Yes. Most RTU installations require building permits and inspections in San José. We handle permit applications, coordinate with the city's building department, and ensure your new system passes all inspections before we consider the work complete.

Are there rebates or incentives for upgrading my RTU in San José?

California utilities often offer rebates for high-efficiency RTU upgrades. We check your eligibility and help with paperwork so you get the financial benefit of your energy-smart investment.

What happens if my RTU fails during peak cooling season?

Call us immediately. We offer emergency repair service to get your system running as quickly as possible. This is why preventive maintenance matters: routine checks catch failing components before they become emergencies.
