Air Conditioning

How often should my air conditioner be serviced?

Most AC systems should be professionally serviced once a year, ideally before the cooling season. Regular maintenance ensures efficient operation, prevents breakdowns, and extends system lifespan.

Why is my AC not cooling properly?

Common causes include dirty filters, low refrigerant, blocked vents, faulty thermostats, dirty coils, or aging equipment. A professional inspection can pinpoint the exact issue.

How long does an air conditioner typically last?

Central AC systems generally last 12–15 years, while ductless mini-splits can last 15–20 years with proper maintenance. Lifespan depends on usage, maintenance, and system quality.

Why is my AC making strange noises?

Rattling, buzzing, or hissing noises may indicate loose parts, debris in the system, refrigerant leaks, or motor issues. Ignoring unusual sounds can lead to bigger repairs.

How often should I replace my AC filter?

Filters should be checked monthly and replaced every 1–3 months, depending on the type of filter, number of occupants, and presence of pets or dust.

Should I repair or replace my AC system?

If your AC is over 12–15 years old, has frequent breakdowns, or shows reduced efficiency, replacement may be more cost-effective than repair. A technician can provide a cost-benefit evaluation.

Can I improve my AC efficiency?

Yes. Simple steps include regular filter changes, cleaning coils, sealing duct leaks, using a programmable thermostat, and keeping vents unobstructed.

Why is my AC freezing up?

Freezing can occur due to low refrigerant, poor airflow, dirty coils, or a malfunctioning fan. Continuing to run a frozen AC can cause permanent damage.

How do I know if my AC refrigerant needs recharging?

Signs of low refrigerant include weak airflow, warm air blowing from vents, hissing sounds, or ice buildup on coils. Only a licensed professional should handle refrigerant.
