A good guideline: when repair costs approach 50% of your system's value, replacement often makes sense. You might also consider replacing your system if it's more than 12 years old or if you've had ongoing problems with it. Even newer systems need regular maintenance to stay efficient and avoid costly repairs down the road. Bud's maintenance plans help keep your system running reliably for years.
