Urgent: Avoid Government Mandate and Price Increase!

Stay Ahead of 2025 Refrigerant Changes with Austin’s Trusted HVAC Experts

Attention Austin homeowners! The clock is ticking—starting in 2025, a government mandate will phase out the R-410A refrigerant used in most HVAC systems. This change could lead to cost increases, with system prices expected to rise by 20% or more.

At McCullough Heating & Air Conditioning, we’re not just here to keep your home cool—we’re here to save you from paying thousands more if you wait. The time to act is NOW. Lock in today’s prices and upgrade before the mandate takes effect!

Why Austin Homeowners Should Act Now:

  • Beat the 2025 Mandate: The new refrigerant, R-454B, requires HVAC systems to be built with specialized components due to its mild flammability, leading to higher costs for new systems. Take advantage of today’s lower prices before the switch happens!
  • Flexible Financing: With financing as low as $72/month, you can get a top-tier system without stretching your budget.
  • Qualify for Federal Tax Credits and Utility Rebates: Save up to $2,600 on energy-efficient systems by acting now.

Limited Availability of R-410A Systems: The longer you wait, the harder it will be to find these systems—and the higher the costs could be down the road.
