SEER Ratings and What They Mean for Your Energy Bills
Modern air conditioners carry a Seasonal Energy Efficiency Ratio rating, or SEER, which measures how much cooling output the system delivers per unit of energy consumed across a typical cooling season. Federal minimums for new residential equipment currently range from SEER 14 to 15, depending on the region, while high-efficiency units reach SEER 20 and above.
The efficiency premium pays off most in climates with long cooling seasons, and Northern Virginia's summer is substantial enough to make that math meaningful. A significant SEER upgrade on a system running five or six months a year can produce real savings over the life of the equipment. That said, the highest-efficiency options aren't always the right fit for every home's existing ductwork and infrastructure, and we'll give you an honest picture of where the value actually lies.

What Happens to Ductwork When a System Is Replaced
A new, efficient air conditioning unit connected to aging, leaking ductwork will underperform no matter what its efficiency rating says on paper.
The U.S. Department of Energy estimates that duct leakage accounts for up to 30 percent of cooling loss in a typical home. In Fairfax County's older housing stock, where original ductwork may be several decades old, and connections may have loosened or deteriorated, taking a look at the duct system is a natural part of any replacement conversation.
Sealing and insulating the ducts can improve how well a new system performs throughout the home, particularly in houses where certain rooms have always run warmer or cooler than the rest.
At Long's Corporation, a replacement installation means looking at the whole picture, not just the equipment being swapped out. Call (571) 470-5898 or contact us online to schedule AC installation and replacement in Fairfax, VA.
