Common AC Problems In Northfield – FAQ
Why does my AC freeze up in the middle of summer?
Your AC might freeze due to restricted airflow, low refrigerant, or dirty filters. It’s about as welcome as a blizzard in July, but usually fixable with proper maintenance.
How often should I replace my AC filter in Northfield?
During our Minnesota summers, replace filters every 30-60 days. If you’ve got more pets than the Northfield Pet Shoppe, bump that up to monthly.
What’s that weird smell coming from my AC?
Could be anything from mold (thanks, Minnesota humidity!) to electrical issues. If it smells mustier than the Historical Society’s basement, get it checked out.
Why does my AC run constantly during Northfield summers?
Between our humidity and summer temps higher than Ole’s GPA, constant running isn’t unusual. But if it’s running more than a Carleton cross country team, something might be wrong.
How can I lower my AC bill during peak summer months?
Set your thermostat to 78°F (you’re Minnesotan, you can handle it!), use ceiling fans, and close blinds during peak sun hours. Saves more money than finding free parking downtown!
Why is my AC making a noise louder than the train at 3am?
Could be loose parts, failing motors, or debris. If it’s louder than the Jesse James Days reenactment, call a professional quick!
How long should my AC last in Minnesota’s climate?
With proper maintenance, 12-15 years. That’s shorter than the wait for a table at Reunion during parents’ weekend, but longer than most Minnesota winters feel.
Should I cover my AC unit during winter?
You betcha! But don’t wrap it tighter than a Minnesota goodbye – it needs some breathing room to prevent moisture buildup.
