Secure 179D Tax Deduction with APR Control

Secure 179D Tax Deduction with APR Control

Section 179D tax deduction savings offers contractors, engineers, and building owners a major opportunity to cut project costs. The deduction rewards energy-efficient upgrades to commercial buildings—covering HVAC systems, lighting, and envelope improvements—with significant tax benefits.

But here’s the challenge: all qualifying projects must go into service by June 30, 2026. With supply chain constraints and long lead times for new variable speed HVAC equipment, this deadline could easily slip out of reach. Fortunately, there’s a proven solution that can help keep your projects moving forward: the Rawal Devices APR Control.

Don’t lose thousands in tax savings waiting on a supply chain that won’t wait for the IRS. Act today to keep your project eligible.

Why Lead Times Threaten 179D Projects

The race to upgrade HVAC systems before the 2026 deadline is putting pressure on equipment manufacturers. Variable speed equipment, often specified in energy efficiency designs, can have lead times stretching months beyond project schedules. Delays put contractors and engineers at risk of missing deadlines. The risk isn’t just a delay; it’s a total forfeiture of your 179D deduction. If the project isn’t in service by June 30, 2026, the tax benefit is gone. The clock is running out.

Each month of delay increases operating costs and prevents building owners from gaining efficiency benefits.

A Proven Alternative: The APR Control

Stop betting your project’s financial outcome on unreliable equipment lead times. There is an immediate, retrofit-ready alternative. Rawal Devices’ APR Control is a proven, cost-effective solution that works on new or existing constant-volume HVAC systems. It modulates refrigerant flow to give traditional equipment variable capacity, improving efficiency and handling part-load conditions with precision.

Key benefits of the APR Control include:

  • Keeps projects on schedule: Installable immediately without waiting on long equipment lead times.
  • Retrofit-ready: Works with existing HVAC units—no need for full system replacement.
  • Cost savings: Extends the life of existing equipment while deferring capital expenditures.
The APR Control is available NOW. You don’t have to wait months for a variable speed unit and risk losing your 179D savings. This could be the only way to guarantee you meet the fixed 2026 deadline for your HVAC upgrades in most cases.

How APR Control Helps HVAC Projects Qualify for the 179D Tax Deduction

To qualify for the section 179D tax deduction, energy savings must meet thresholds established by ASHRAE standards. The APR Control boosts part-load efficiency and cuts energy waste, allowing standard HVAC systems to perform like variable-speed units at a much lower cost.

That means contractors and engineers can still design and deliver qualifying projects without relying solely on variable speed equipment availability.
