Signs You Need A New AC

You most likely need a new AC if your current unit:

  • Is more than 10 years old. Most ACs have a lifespan of 10-15 years, so if your unit is approaching that age, it's probably worth it to get a new one.
  • Struggles to keep you comfortable. This could be a sign that your AC is the wrong size or nearing the end of its life. Either way, it's usually best to invest in a new unit.
  • Needs frequent repairs. This is often a sign that your AC is on its way out. It usually pays off in the long run to invest in a new unit rather than constantly spend money on expensive repairs.
