How to Fix Common AC Problems

When summer heat sets in, a reliable air conditioner makes all the difference. Homeowners dealing with cooling issues often turn to Anderson’s Residential Heating and AC Inc, a family-owned business serving Blaine and the surrounding area for decades. While some problems need a professional’s touch, there are a few common AC issues that homeowners can troubleshoot on their own before scheduling service.

When the AC Won’t Turn On

A unit that refuses to start can be frustrating, especially on a hot day. Before calling for repairs, it’s worth checking the thermostat settings. Make sure it’s set to ‘cool’ and the temperature is lower than the current indoor reading. If that doesn’t work, inspect the circuit breaker to ensure it hasn’t tripped. Sometimes, replacing the thermostat batteries is all it takes to restore power. If these steps don’t solve the problem, it’s best to call a qualified technician.

Weak or Uneven Airflow

Uneven cooling or weak airflow is one of the most common reasons residents call for AC repairs in Blaine, MN. The culprit is often a clogged air filter that restricts circulation. Filters should be replaced regularly to keep the system running smoothly. Another possibility is blocked vents—furniture, rugs, or curtains can prevent air from moving freely. If airflow is still weak after these fixes, the issue could be with the blower motor or ductwork, which requires professional inspection.

Strange Noises or Odors

Unusual sounds coming from an air conditioner should never be ignored. Banging or rattling often points to loose parts, while squealing may signal a worn belt. Musty or burning smells can indicate mould growth or electrical problems. Homeowners should turn off the unit immediately if these signs appear. Addressing the issue early prevents bigger, more expensive repairs down the line.

Water Leaks Around the Unit

Puddles forming near an AC system can be alarming. The cause is usually a clogged condensate drain line, which can sometimes be cleared with a wet/dry vacuum. If water continues to leak, the problem may involve frozen evaporator coils or low refrigerant levels. These issues require professional service, as they involve delicate components that shouldn’t be handled without training.

Warm Air Instead of Cool

Few things are more frustrating than an air conditioner that blows warm air. First, check the air filter, as a dirty one can block cooling. If the filter is clean, the issue may stem from low refrigerant levels or a failing compressor. These are not DIY fixes, and a licensed technician should be called immediately.
