What Causes Low Refrigerant in AC?

August 19, 2025

Of all the equipment in your Anoka, MN home, your air conditioner may be the costliest. Quality cooling systems represent significant investments for homeowners.

How to Check Air Ducts for Leaks?

August 12, 2025

Wondering how to check your air ducts for leaks? Run your HVAC system, then feel along accessible ductwork in attics, basements, and crawl spaces for air escaping at the seams and joints. Watch for the common signs too: uneven temperatures from room to room, rising energy bills, and drafts near walls and ceilings. For hidden leaks, use a smoke stick (the smoke drifts toward gaps) or a thermal camera, and for a precise measurement, a professional can run a duct-blower pressure test. Once you find the leaks, seal them with mastic or metal-backed tape — never cloth duct tape, which

Is it Cheaper to Run AC On Fan?

August 5, 2025

Is it cheaper to run your AC on fan mode? Yes — running just the blower fan uses far less energy than running the air conditioner, because the compressor (the AC’s biggest energy user) stays off. But cheaper doesn’t mean smarter in summer: fan mode only circulates air, it doesn’t cool. Worse, switching to fan mode right after cooling re-evaporates the moisture on the coil and pumps humidity back into your home, making it feel hotter and stickier — so you end up running the AC again anyway. For hot Minnesota summers, stick with cooling mode; save fan mode for

How to Test if an AC Fan Motor Is Bad?

July 20, 2025

Wondering if your AC fan motor has gone bad? The most reliable signs are: the fan won’t spin while the compressor runs, it spins slowly or only intermittently, it makes a screeching or rattling noise, it keeps running after the system shuts off, or the AC repeatedly trips the breaker. Because the fan not spinning can also be caused by a failed start capacitor (a cheaper fix) or worn bearings, the true cause is confirmed with a multimeter continuity test on the motor windings — a diagnosis best left to an HVAC technician, since testing a charged capacitor can cause

How Long Do Whole-Home Generators Typically Last?

July 3, 2025

Wondering how long a whole-home generator will last? A quality standby generator is rated for roughly 1,500 to 3,000 run hours, which works out to about 15 to 25 years of typical use — and 30 to 40 years or more for units that don’t run often. The single biggest factor is maintenance: staying on top of annual oil, filter and spark-plug service, exercising the unit monthly, and keeping a three-foot clearance for airflow can push a generator toward the high end of that range, while heavy loads, poor airflow and skipped maintenance shorten it. Most homes

When Should You Use Your Air Conditioner’s Fan Mode?

June 20, 2025

When should you use your air conditioner’s fan mode? Fan mode runs your AC’s blower without the compressor, circulating air without cooling it. Use it in the early morning or late evening when it’s mild out, on high-pollen days to filter indoor air, and whenever you want gentle air circulation without paying to run the compressor — it uses only about 60 to 150 watts versus 1,000 to 4,500 for full cooling. Avoid fan mode on hot afternoons (it just circulates warm air) and don’t rely on it to control humidity, since it doesn’t remove moisture. The
