Why isn’t my AC blowing cold air after winter?

After sitting unused during winter, AC systems may develop issues such as clogged air filters, refrigerant problems, dirty coils, or electrical component wear. A professional tune-up can identify the cause.

Is it normal for an AC system to have problems after sitting unused?

Yes. Debris buildup, worn components, or minor issues may not become noticeable until the system is turned on for cooling in spring.

How often should I schedule an AC tune-up?

Most homeowners schedule AC maintenance once a year, typically in spring before peak cooling season.

Can a dirty air filter prevent my AC from cooling?

Yes. A clogged air filter restricts airflow, which can reduce cooling performance and increase strain on the system.

What role does refrigerant play in cooling?

Refrigerant absorbs heat from inside your home and releases it outdoors. Low refrigerant levels can prevent the AC from blowing cold air.

Why is my AC running but not cooling the house?

Possible causes include thermostat issues, low refrigerant, airflow restrictions, dirty coils, or ductwork problems that require professional inspection.

Should I try to fix my AC myself?

Homeowners can replace filters and clear debris, but refrigerant handling and electrical repairs should be performed by trained HVAC professionals.

What happens during a professional AC tune-up?

A tune-up typically includes inspecting components, checking refrigerant levels, testing electrical connections, cleaning coils, verifying airflow, and identifying potential issues.

Can skipping maintenance lead to bigger problems?

Yes. Small issues can become larger repairs if left unaddressed, especially during peak summer demand.

When is the best time to schedule AC maintenance?

Early spring is ideal, before temperatures rise and cooling demand increases.
