Three months of hard work, then hail season
Blaine only needs cooling from June through August, but those three months average 80°F in the afternoon. That means the compressor runs hard in a short stretch rather than easing into the season, and anything already weak in the system tends to show itself fast once the heat sets in.
Anoka County has logged 75 hail events over the past ten years, with stones up to 3 inches. Hail that size can dent or crack the fins on an outdoor condenser coil, and the 40 damaging wind events over the same period can knock the unit out of level or loosen its electrical connections. A coil that is bent or blocked cannot move heat the way it should, and the air coming out of your vents turns warm even though the system is running.

A new air conditioner would save little on running costs in Anoka County, so the repair decision comes down to the unit's condition.
Estimates for a typical Anoka County home, compared with an older unit built to the previous federal minimum, from EIA household energy data, Minnesota fuel prices and NOAA climate normals. Your home will differ.
Repair makes sense when a part like a capacitor or contactor has failed.
Replacement makes sense when the compressor has failed or the system uses R-22 refrigerant, which is no longer made.
Minnesota has no state license for HVAC contractors.
Minnesota does not require HVAC contractors to hold a state license or even register with the state before doing home repair work. There is no state test behind the work and no state record of who is doing it.
For a repair like this, the protection that does exist comes from federal law, not the state. Air conditioner repair means opening the refrigerant side of the system, and any technician who does that, anywhere in the country, has to hold EPA Section 608 certification. That certification is the one credential you can count on here.

- Why is my AC not blowing cold air?
- The most common cause is a dirty air filter cutting off airflow across the coil, which can make the coil ice up and stop cooling altogether. Low refrigerant from a leak is another common cause, and that takes a licensed technician to find and fix since it means opening the refrigerant side of the system. A failing compressor will also leave you with air moving but no cold behind it. Check the filter first, and if it's clean, the system needs a contractor to look at the refrigerant charge and the compressor.
- Why is my AC leaking water?
- Warm air blowing across the indoor coil creates condensation, and that water is supposed to drain out through a condensate line. If that line clogs with dirt or algae, the water backs up and drips or pools near the unit instead of draining outside. A dirty air filter can also cause this by making the coil so cold it freezes, then leaks water as it thaws. Clearing the drain line usually solves it, but if it keeps happening the coil or the drain pan may need a closer look.
- Why won't my AC turn on?
- Start with the thermostat, since dead batteries or a setting knocked off cool will stop the system before it even tries to start. A tripped breaker or a blown fuse at the outdoor unit is the next thing to check. If power is reaching the unit and it still won't start, the capacitor that gets the compressor running may have failed, and that's a repair for a licensed technician. Minnesota doesn't require a state license for HVAC work, but anyone opening the refrigerant side of your AC still has to hold federal EPA certification.
