AC repair in Green Isle costs the same as anywhere we work, with no mileage added: a $79 trip charge that's waived when you approve the repair, then a written flat-rate price before any work. We're open 7 days, 7am–9pm, and many Green Isle homes added central air years after their furnaces went in.
Most Green Isle homes picked up central air after the fact, with a coil set on whatever furnace was there at the time. When the furnace was later replaced, the coil sometimes stayed, so it's common to find an older coil paired with a newer furnace and a condenser of a third age. Mismatched pieces like that leak at old brazed joints, freeze from poor airflow and lose capacity, so we check the whole chain before blaming one part.
Farmhouses stretch a single system further than it was meant to go, and upstairs bedrooms in the older two-stories run warm when there's no return to pull heat back down. Condensers on open farm lots sit in full sun all afternoon, which wears out a weak capacitor sooner. Xcel Energy supplies most of the town's electricity, and some properties are on Minnesota Valley Electric Cooperative. We test capacitors, contactors and the charge before quoting anything larger.

The indoor blower is running, but nothing outside is. Check the breaker for the condenser and the disconnect box beside it. If both are on, the likely causes are a contactor that won't pull in, a failed capacitor, or a low-voltage fault such as a chewed thermostat wire or a tripped float switch on the condensate drain. Turn the cooling off so the coil doesn't freeze, and call us for a written price.
Usually not, if the coil isn't leaking. Bent fins block airflow and cut capacity, but they can often be straightened with a fin comb, and we check the charge to confirm no tubes were punctured. If hail cracked a tube or the fins are crushed flat across most of the coil, replacement may make more sense. Hail damage is often an insurance question, so photograph the unit before anything is cleaned up.
