Air Conditioning Replacement

For more than four decades discerning homeowners have turned to Weber & Grahn when it’s time to replace their air conditioning systems. We’ve earned a reputation for integrity that our clients appreciate. They trust us because we’ve earned their trust throughout the years as we maintained and repaired their existing systems.

Repair…or replace?Timely service calls by our trained technicians

Once a system begins to show the typical signs of aging, such as frequent breakdowns or inefficient performance, the most common question will be “Should I repair or replace my system?” Once a system begins to fail, the chances are high enough that it will only continue to break down even further So instead of attempting to put your money into a system that will only need more major repairs, put into consideration that replacing the unit itself will safely be your best bet. Considering that you could reduce your energy bills by more than half with new high-efficiency equipment; keeping your old system will actually cost you more than you may realize.

The Experience That Matters…

As Warranty Service Providers for numerous manufacturers, Weber & Grahn knows the systems we install inside and out. Our extensive knowledge of these systems makes it even easier for our skilled technicians to professionally install a wide variety of air conditioning systems.

  • Carrier
  • Bryant

Providing options that make you comfortable.

Your new air conditioning and heating system should provide comfort even before it’s installed. At Weber & Grahn, we take the time to explain why we recommend a particular system. You’ll know as much as you want to know about the reasons behind our recommendation. We’ll address any questions or concerns you may have and walk you through the process so you’ll know exactly what to expect. And should you simply want us to handle everything from system selection to installation, we’ll do that, too. Either way, you’ll be comfortable even before the job is finished.
