Restore Lost Cooling and Heating Performance

Over time, internal buildup can reduce a system’s ability to transfer heat. Restoration can help the AC or heat pump, heating or colling mode, operate closer to it's original performance.

May Prevent Premature Replacement

Many systems are replaced due to performance decline, not mechanical failure. Performance restoration may extend system life and delay costly replacement.

Used in Hospitals, Government and Commercial Facilities

Performance restoration has been used in mission-critical systems where reliability and efficiency are essential. Now available to residential HVAC Contractors.

Lower Runtime and Energy Consumption

When heat transfer improves, systems often run less frequently to maintain comfort, which may reduce energy use and improve temperature stability.

“ACFlush is a performance restoration chemistry, not a solvent flush”. We don’t force anything through the system to wash out debris. Instead, the chemistry is introduced through the low-side service port and circulates with the refrigerant to remove the thermal barrier, an invisible film of oil that builds up on the inner coil walls over time. It’s called Oil Fouling. (Google ASHRAE Oil Fouling) This technology has been utilized in commercial, military, and mission-critical facilities for over 25 years to stabilize heat transfer, restore original system capacity and performance, including at NASA.

Big money in system replacement

Pride and Peace of Mind In the Repair...

Technicians take pride in repairs. Customers leave 5-star reviews and referrals when they do.

"For over 25 years, EnviroTemp has been in the trenches of the HVAC industry. We understand the pressure to hit replacement targets, but we also know the value of a high-margin repair that builds lifelong customer trust.".

As a Former Comfort Advisor...

"I've seen it all—from homeowners ready to hand over their credit card for the best of the best, top of the line system to those asking if we have anything cheaper, they'll even take used. Restoration gives you a third option that actually works."

How Performance Restoration Works in Your Home

A qualified HVAC contractor evaluates system performance and restores internal heat transfer when appropriate

Evaluate System Performance

Contractors measure critical data—including temperature splits, airflow, and runtime—to identify performance decline in mechanically sound systems. This evaluation determines if internal restoration is the correct path to return the equipment to its design specifications

Restore Internal Heat Transfer

This procedure removes the internal 'thermal barrier' (oil fouling) that traps heat inside the system. By clearing these restrictions, we allow your heat pump or AC to breathe and transfer heat at original efficiency in both summer and winter cycles

Verify Performance Restoration

We don't just guess; we measure. Post-treatment readings verify that the "thermal barrier" is gone—resulting in colder air in the summer, hotter air (heat pumps) in the winter, and a system that finally cycles off because it reached your thermostat's goal faster.

Capture Same-Call Revenue

By restoring internal heat-transfer performance, ACFlush can reduce the strain that builds inside the system over time.

Many homeowners find that once performance is restored, their system delivers the comfort they need — allowing them to plan for replacement on their terms instead of rushing into it.
