5 Things that are killing Your Commercial Air Conditioning?

5 Things That Are Killing Your Commercial Package Rooftop Unit (RTU) — And How to Extend Its Life

Your commercial package rooftop unit (RTU) is one of the most expensive systems in your building. Without proper maintenance, it can fail years before its expected lifespan, leading to costly repairs, business interruptions, and uncomfortable indoor conditions.

Here are the 5 biggest reasons commercial rooftop HVAC units fail prematurely and what you can do to protect your investment.

1. Dirty Condenser & Evaporator Coils

Dirty coils force your HVAC system to work harder, increasing energy consumption, overheating compressors, and reducing cooling capacity.

How to prevent it:

• Schedule professional coil cleaning at least twice a year.

• Replace clogged air filters regularly.

• Keep debris away from the rooftop unit.

2. Clogged Drain Lines

Blocked condensate drains cause water backups that can damage ceilings, insulation, electrical components, and even shut down your unit.

How to prevent it:

• Clean drain lines during every preventive maintenance visit.

• Inspect drain pans for algae and debris.

• Install drain safety switches when appropriate.

3. Low Refrigerant or Refrigerant Leaks

Operating with low refrigerant causes compressors to overheat and fail, often resulting in one of the most expensive HVAC repairs.

How to prevent it:

• Have refrigerant levels checked by a licensed HVAC technician.

• Repair leaks immediately instead of repeatedly adding refrigerant.

• Perform annual leak inspections.

4. Lack of Preventive Maintenance

Skipping maintenance allows small issues to become major failures, increasing repair costs and shortening equipment life.

How to prevent it:

• Schedule preventive maintenance every spring and fall.

• Inspect belts, motors, electrical connections, contactors, capacitors, and safety controls.

• Maintain detailed service records.

5. Poor Airflow

Restricted airflow caused by dirty filters, blocked ducts, or failing blower components increases operating temperatures and reduces efficiency.

How to prevent it:

• Replace filters on schedule.

• Keep supply and return vents unobstructed.

• Inspect blower wheels, belts, and motors regularly.

Protect Your Investment

A commercial package rooftop unit can often last 15–20 years when properly maintained. Neglecting routine service can significantly shorten its lifespan while increasing energy costs and unexpected breakdowns.
