Signs You Need a New AC
Repair vs Replace Guidance.
Your AC won't last forever. If you're experiencing any of these, it may be time for a replacement rather than another repair.
AC Won’t Turn On
Won’t start, or keeps tripping the breaker? The compressor or electrical is likely failing.
Still Uses Freon (R-22)
R-22 is phased out and expensive. Older Freon systems cost more to service than to replace.
Loud Sounds or Short Cycling
Banging, grinding, or a unit that turns on and off constantly means major parts are wearing out.
Won’t Reach the Set Temp
Runs nonstop but never hits the thermostat setting? The system can no longer keep up.
Warm, Humid or Icy
Hot or humid rooms, or ice and frost on the tubing, point to a failing or undersized system.
