Frequently Asked Questions About Moore Mechanical's Commercial HVAC RTU Services In Michigan

What is a commercial rooftop unit?

A commercial rooftop unit, commonly called an RTU, is a packaged HVAC system installed on the roof of a commercial building. Depending on the equipment, one unit may provide heating, cooling, ventilation, or a combination of these functions.

Can Moore Mechanical repair an existing rooftop HVAC unit?

Moore Mechanical provides commercial rooftop unit diagnostics and repair. Our technicians will inspect the equipment, identify the cause of the problem, and explain whether repair or replacement is the better option.

How do I know whether to repair or replace my RTU?

The decision depends on the equipment’s age, overall condition, repair history, performance, replacement-part availability, and the cost of the proposed repair. An on-site evaluation provides the information needed to compare both options.

How often should a commercial rooftop unit be maintained?

Many commercial rooftop systems should be professionally inspected before the primary heating and cooling seasons. The ideal schedule can vary based on equipment age, building use, operating conditions, and manufacturer recommendations.

What affects the cost of replacing a commercial rooftop unit?

RTU replacement costs depend on equipment capacity, efficiency, configuration, roof access, crane requirements, electrical or control modifications, curb compatibility, and other installation conditions. Moore Mechanical can evaluate the property and prepare a project-specific estimate.

How long does a rooftop unit replacement take?

The timeline depends on equipment availability, permitting, roof access, crane coordination, and whether modifications are required. Our team will explain the expected schedule before the project begins.
