Air Conditioning Repair Service FAQ
How often should I change my air filters?
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!
What types of air conditioning systems do you service?
We repair all major types including central AC units, ductless mini-splits, window units, and portable systems.
How do I know if my air conditioner needs repair?
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!

How often should I schedule maintenance for my AC unit?
We recommend scheduling professional maintenance for your AC unit at least twice per year, preferably in the spring before the peak cooling season begins and early fall, before the cold winter weather kicks in. 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.

Can regular maintenance prevent the need for repairs?
Yes! Regular maintenance can significantly reduce the likelihood of unexpected HVAC repairs. By keeping your system clean, properly tuned, and running efficiently, maintenance helps catch minor issues before they turn into costly breakdowns.
We recommend bi-annual preventative maintenance—once in the spring for your air conditioner and once in the fall for your heating system. This ensures your HVAC system is prepared for the demands of the upcoming season, improves energy efficiency, and extends the lifespan of your equipment.
Investing in our affordable, routine maintenance now can save you money on emergency repairs and keep your home comfortable year-round. Schedule your preventative maintenance appointment today! 865-388-1712
