AC Replacement in Rosemount, MN

AC installation is obviously appropriate when you’re moving into a new building that doesn’t yet have an indoor cooling system. But when your AC isn’t functioning properly, how do you know when to merely ask for repairs and when to entirely replace your system?

Refrigerant leaks, loud noises, or strange odors coming from your unit, inexplicably exploding energy bills, decreased indoor air quality, and a marked increase in indoor humidity are all signs that your AC needs repairs.

When you notice such things happening more often despite frequent repairs, this is a signal that you should cut your losses and just install a new unit.

Most ACs — whether central systems or ductless mini-splits — can function well, on average, for about 10 to 15 years. Beyond that point, functionality inevitably declines. Parts become old. Persistent use wears on them, and repairs, as mentioned, provide diminishing returns. After 15 years, it’s almost certainly cheaper to just install a new unit.

Not only do old ACs decline in efficiency over time, but technological advances lead to newer and more efficient models. After enough time, these advances accumulate to such a degree that the energy savings from a newer model can more than pay for the cost of replacement before very long.
