Air Conditioning Repair Service FAQ

We recommend changing your air filters every 45 days to keep your HVAC system running efficiently and to maintain good indoor air quality. Regular filter changes help prevent dust, allergens, and debris from clogging your system, which can lead to higher energy bills and reduced performance.

If you have pets, allergies, or live in a high-pollen area, you may need to replace your filters more frequently. Not sure which filter is best for your system? Contact us, and we’ll be happy to help!

We repair all major types including central AC units, ductless mini-splits, window units, and portable systems.

There are several signs that indicate your air conditioner may need repair. If you notice any of the following issues, it’s best to schedule a professional inspection:

• Warm Air – If your AC is blowing warm or weak airflow, it could be a refrigerant issue or a failing compressor.
• Unusual Noises – Banging, grinding, or squealing sounds can signal loose or damaged components.
• Frequent Cycling – If your system turns on and off too often, it may have a thermostat or airflow issue.
• High Energy Bills – A sudden spike in energy costs could mean your AC is working harder than it should.
• Leaks or Moisture Buildup – Excess water or refrigerant leaks around your unit should be checked immediately.
• Bad Odors – Musty or burning smells may indicate mold, electrical problems, or dirty components.

If you’re experiencing any of these problems, don’t wait—contact us today for a professional AC inspection and repair!

Regular maintenance helps ensure your system runs efficiently, extends its lifespan, and prevents costly breakdowns.

During a maintenance visit, our technicians will inspect, clean, and tune up your AC, checking for potential issues before they turn into major problems. If you have an older system or use your AC heavily, you might benefit from biannual maintenance for optimal performance.
