Repair vs. Replacing Chillers
When it comes to commercial HVAC services
in Winston-Salem, chiller systems play a crucial role in keeping buildings comfortable and operations running smoothly. But how long do chillers
last? And when is it better to repair vs. replace? Understanding the lifespan of your chiller system can help you make cost-effective decisions and avoid unexpected downtime.
How Long Do Chiller Systems Last?
The average lifespan of a commercial chiller depends on factors like maintenance, usage, and environmental conditions.
Air-Cooled Chillers: 15–20 years
Water-Cooled Chillers: 20–30 years
Absorption Chillers: 25–30 years
With regular maintenance
and chiller repairs, many systems can last beyond their expected life. However, as chillers age, they become less efficient, leading to higher energy costs and frequent breakdowns.
Chiller Repairs vs. Chiller Replacement
When to Repair a Chiller?
If your chiller is still relatively new and issues are minor, repairs can extend its life and keep costs down. Signs your chiller may only need a repair include:
✅ Minor Performance Issues – If cooling output is slightly reduced but overall efficiency remains stable.
✅ Leaks or Refrigerant Issues
– Small refrigerant leaks or sensor malfunctions can often be repaired cost-effectively.
✅ Inconsistent Temperature Control – If fluctuations are caused by a faulty sensor, thermostat, or minor electrical issue.
✅ Mechanical Wear & Tear – Bearings, fans, and pumps can be replaced without needing a full system replacement.
Routine commercial HVAC services in Winston-Salem, including preventive maintenance
and regular tune-ups, can reduce the need for major chiller repairs.
When to Replace a Chiller?
At some point, chiller repairs become too costly, and a full replacement is the smarter choice. Signs it’s time for a new system include:
❌ Frequent Breakdowns – If you’re constantly calling for emergency chiller repairs, replacement might be more cost-effective.
❌ Rising Energy Costs
– Older chillers lose efficiency, leading to skyrocketing utility bills. New systems are far more energy-efficient.
❌ Obsolete Technology – If your chiller uses outdated refrigerants (like R-22, which is being phased out), replacement is necessary.
❌ Inconsistent Performance – If your chiller struggles to maintain temperatures, it could indicate major internal failure.
Upgrading to a modern, energy-efficient chiller system
can reduce commercial HVAC costs while improving reliability.
How to Extend the Life of Your Chiller in Winston-Salem
For businesses in Winston-Salem, regular maintenance is the key to maximizing the lifespan of your chiller system. Here’s how:
🔧 Schedule Preventative Maintenance – Regular inspections catch issues before they turn into major failures.
💧 Optimize Water Treatment – For water-cooled chillers, proper water treatment prevents corrosion and scaling.
🛠️ Upgrade Components – Instead of replacing the entire unit, upgrading motors, compressors, and controls can improve efficiency.
📊 Monitor Performance with BAS/BMS – Modern building automation systems (BAS) help track chiller efficiency in real time.
By working with an experienced commercial HVAC service provider
in Winston-Salem, you can ensure your chiller remains efficient and reliable for years to come.
