Chemical treatments are still common, but they come with real downsides:

They don’t remove existing buildup, only soften the surface
Bio-slime quickly returns, often thicker than before
Repeated use can contribute to corrosion of coils, fittings, and drain components
Harsh chemicals introduce unnecessary environmental and indoor air concerns

Most importantly: 👉 Chemicals are reactive, not preventative.

The Problem With “Flush It When It Clogs”

Traditional drain maintenance usually happens after damage has already started:

Service calls during peak season
Emergency shutoffs
Water damage claims
Frustrated homeowners

At that point, everyone loses:

The homeowner pays more
The technician wastes time on cleanup
The system takes unnecessary wear

A Better Approach: Automatic, Preventative Drain Maintenance

This is where AC NeverClog™ changes the game!

Instead of reacting to clogs, it works automatically to eliminate them before the growth starts.

How it works:

Runs a short, scheduled cycle to evacuate any buildup
Physically removes bio-slime before it can accumulate or even grow
Requires no chemicals
No homeowner interaction
No recurring service calls just to “treat” a drain

It’s a set-it-and-forget-it solution designed for real-world HVAC systems — especially tight air handlers and high-humidity environments.

Why Homeowners Love It (And Techs Do Too)

For homeowners:

Fewer breakdowns
No surprise leaks
Peace of mind year-round

For HVAC professionals:

Fewer emergency callbacks
Faster installs
A high-value add-on customers actually understand
Protection against repeat drain issues

The Bottom Line

AC drain line clogs aren’t bad luck, they’re the result of unintentional neglect (a lack of proactive maintenance), biology, and outdated solutions.

Preventing them requires:
