Is it time for an AC Replacement?
If your air conditioner is older than 10 years, hasn’t been regularly maintained, and is no longer covered by a manufacturer warranty, it may be more expensive to repair the unit. Most new replacements come with a 10-year warranty, but remember, every system is unique. Need help choosing the right AC unit?
