Repairing Your Rooftop Unit

Commercial rooftop units (RTUs) are a perfect heating, ventilation, and air conditioning (HVAC) solution for many businesses in Downers Grove, and the surrounding areas.

These space-saving units are packaged systems with all components housed in the same compact box. They are easy to maintain and repair, and less susceptible to vandalism and accidents than units installed at ground level.

On the downside, rooftop units are vulnerable to lightning and high winds, and like any other commercial HVAC system, they can develop mechanical and electrical problems. Issues may go undetected because rooftop units are out of sight and often out of mind.

Illinois Packaged Unit Repairs

If you notice any signs that your rooftop unit needs attention, call us at Amber Mechanical for a diagnosis and repair if necessary. The sooner one of our qualified technicians can inspect the unit, the less likely your system will break down and disrupt your Downers Grove business.

A broken RTU unit can affect employees, customers, building occupants, and visitors. Extreme indoor temperatures may cause a building closure or lower work productivity.

You can avoid an RTU breakdown by resolving the issue before it worsens. But how do you know your equipment is malfunctioning and heading toward a likely breakdown? You can look for cues.

Signs Your Rooftop Packaged Unit Has a Problem

• Noises: A rattling or grinding sound may indicate components are loose.
• Water: A pool around your rooftop unit could signal coil or drainage problems.
• Odor: If you detect a burning smell, your RTU may have an electrical issue or burned-out component.
• Indoor Air Quality (IAQ): A high humidity level and musty odor point to a potential problem with your RTU.
• Short Cycling: Your RTU turns on for a few minutes and then shuts off for a few minutes before repeating the cycle. It struggles to complete a full cooling or heating cycle.
• Temperature Fluctuation: A malfunctioning blower may cause inconsistent temperatures throughout your building.
• Energy Bills: Higher energy bills may indicate a loss of efficiency and more energy consumption. A dirty filter or refrigerant leak could be the culprit.

Problems and Fixes

Typical problems with rooftop units include refrigerant leaks, faulty wiring, motor failure, dirty coils, worn or damaged components, blocked condensate lines, and malfunctioning sensors or control boards.

We can resolve some issues by repairing or cleaning components. Failed motors or sensors may need replacement. 

Schedule Preventative Maintenance

Routine maintenance is the best solution to avoid breakdowns and repairs. At Amber Mechanical, we can work with you to create a maintenance schedule that makes sense for your rooftop unit. Preventative maintenance is crucial for your HVAC system:

• Efficiency: Inspecting and cleaning your RTU can improve efficiency.
• Longevity: Maintaining your HVAC system extends its lifespan.
• Early Detection: An HVAC professional can intervene and repair issues before they become major, costly problems.
• IAQ: A clean, well-maintained RTU can improve indoor air quality.

The U.S. Department of Energy says operations and maintenance best practices can save up to 20 percent on energy bills.
