The cheapest coil rarely stays cheap. Cut corners on copper, bonding or testing and you pay for it in energy, downtime and early replacement.
Here's the true cost.
Thin or impure copper
Cutting copper saves rupees today and costs efficiency and life tomorrow. Purity and wall thickness matter.
Skipped testing
An untested coil may leak in the field — lost charge, callbacks and downtime. Testing every coil prevents this.
Poor bonding and efficiency
A loose tube-to-fin bond wastes energy every hour the system runs. Over years, that dwarfs the purchase price.
Value, not just price
A well-built coil costs a little more up front and far less over its life. That's the case for a quality coil.
Key takeaways
- Cheap copper costs efficiency and life
- Skipped testing invites field failures
- Poor bonding wastes energy continuously
- Judge value over the coil's whole life
