Gas Furnace Replacements & Installations

When your gas furnace is old, it has a much lower AFUE rating compared to modern gas furnaces with AFUE ratings between 95 and 100 percent. You might have a system running around 80% AFUE which is okay, but with higher efficiencies, you can save a lot of money with a new system replacement! The professionals at Desert Diamond Air specialize in new gas furnace replacements in Phoenix, Scottsdale, Peoria, Glendale, Mesa, Sun City, & Surprise, AZ. If you are curious if the replacement is worth it, we can give you the estimated savings you’ll receive through an advanced AFUE Energy Savings Calculator.
