Commonly Asked Questions Regarding Air Conditioning Systems
Most HVAC experts recommend a professional AC tune-up once a year, preferably in the spring before the cooling season starts. This helps detect issues early and keeps the system running efficiently during Oregon’s warmer months.
Common warning signs include:
- Strange noises (banging, rattling, grinding)
- Uneven or weak airflow
- Burning or musty smells
- Furnace turning on and off frequently
- Higher energy bills
- Cold spots throughout the home
If you notice any of these, schedule a diagnostic before the system fails completely.
A continuously running AC usually points to:
- Dirty coils
- Incorrect thermostat settings
- Low refrigerant
- Leaky ductwork
- Poor insulation
This increases energy bills and signals the need for maintenance.
A soft humming sound is normal, but loud buzzing, rattling, or grinding indicates:
- Loose or damaged parts
- Fan motor issues
- Debris inside the unit
- A struggling compressor
Unusual noises should be checked promptly.
Frozen coils are caused by:
- Clogged air filters
- Blocked return vents
- Dirt on the evaporator coil
- Low refrigerant
- Poor airflow
Turn off your AC to let the ice melt and schedule service to prevent damage.
A musty smell often means moisture buildup or mold inside the system. Common causes include:
- Clogged condensate drain line
- Dirty coils
- High indoor humidity
- Wet or dusty ductwork
A cleaning and drain line flush usually resolves the issue.
Signs of low refrigerant include:
- Warm air from vents
- Ice on the coil or refrigerant line
- AC running nonstop
- Hissing or bubbling sounds
- Sudden increase in energy bills
Only a licensed technician can test and refill refrigerant safely.
Common causes include:
- A clogged condensate drain line
- A cracked or rusted drain pan
- Frozen coils melting
- Excess humidity
Leaks should be addressed immediately to avoid water damage.
Homeowners can:
- Replace air filters
- Clean indoor vents
- Remove debris around the outdoor unit
- Check thermostat settings
- Inspect the drain line for simple clogs
Deep cleaning, electrical checks, and refrigerant work should be left to professionals.
Frequent cycling (short cycling) is caused by:
- Dirty filters
- Thermostat issues
- Electrical problems
- Oversized AC units
- Frozen coils
Short cycling reduces efficiency and often signals a system issue.
Most AC systems last 12–15 years. Oregon’s mild summers may extend system life, but humidity and occasional heat waves still contribute to wear and tear.
Yes. Skipping maintenance often leads to:
- Dirt buildup on coils
- Clogged drains
- Low airflow
- Higher utility bills
- Early breakdowns
Annual tune-ups keep the system efficient and help prevent surprise repairs.
