If your rooftop HVAC unit (RTU) is acting flinchy—making noise, losing efficiency, or driving up energy bills—it’s time for a business‑critical decision. Should you repair it or get a brand new one? This guide helps Las Vegas business owners choose wisely.
Understanding Rooftop HVAC Units
Rooftop units combine cooling, heating, and ventilation in one compact system installed on commercial roofs. Their long lifespan (15–20 years) and easy access make them popular for retail spaces, offices, restaurants, and more.
Signs Your Rooftop Unit Needs Attention
- Age Over 15–20 Years: Most RTUs lose efficiency and reliability past 15 years.
- Rising Energy Bills: An older unit may run constantly to maintain temperatures, resulting in higher utility costs.
- Frequent Repairs or Breakdowns: When condenser coils, fan motors, or compressors fail repeatedly, repair costs can exceed value.
- Inconsistent Temperature or Poor Comfort: Hot/cold zones, humidity issues, or uneven airflow signal inefficiency.
- Loud or Unusual Noises: Grinding, screeching, or rattling suggest mechanical wear or refrigerant issues.
- Outdated Refrigerant or Regulations: Systems still using phased‑out refrigerants (like R‑22) are environmentally unfriendly and costly.

What to Expect in Costs
- Annual Maintenance: $200–$450 per unit
- Common Repairs: Compressor ($1,000–$2,700), Coil ($675–$2,150), Capacitor ($115–$375)
- Replacement Cost: Starts from $4,000–$12,000
When Retrofit Might Be the Sweet Spot
If your RTU is around 10–15 years old and structurally sound, but inefficient, consider upgrading:
- Install variable‑speed motors
- Upgrade controls and sensors
- Add economizer or smart thermostat
Retrofitting can cut energy use by 20–40% and extend unit life without full replacement.
