When to Replace Your AC System in Salt Lake City
Every air conditioning system has a finite lifespan. In the Salt Lake City area, where systems work harder due to altitude and extreme summer heat, the average central AC system lasts 12 to 18 years with proper maintenance. Without maintenance, that drops to 8 to 12 years.
Our partner technicians help you decide between repair and replacement using data, not sales tactics. They will show you the cost comparison over 3, 5, and 10 years so you can make the decision that makes financial sense for your situation.
Signs Your AC Needs Replacement
Age. If your system is over 12 years old, start planning. Over 15, replacement is likely imminent. Over 18, you are on borrowed time with every cooling season.
Rising repair costs. Track your repair spending. If you have spent more than $1,500 on repairs in the past two years, that money would have been better applied toward a new system.
Declining performance. If your system no longer keeps your home comfortable on days above 95 degrees despite recent repairs and maintenance, it may have lost too much capacity to be worth saving.
R-22 refrigerant. If your system uses R-22, which was phased out of production in 2020, each refrigerant recharge costs $100 to $200+ per pound and prices continue to climb. Replacing with a modern R-410A system eliminates this ongoing cost.
Energy bills climbing. Older 10 SEER systems use 60 to 100 percent more electricity than modern 16 to 20 SEER systems. In Salt Lake City's 3 to 4 month cooling season, upgrading from a 10 SEER to a 16 SEER system can save $300 to $600 per summer.
