Even if your system is still running, it might be overdue for a professional checkup. Watch for these tell-tale signs that you need expert AC maintenance services:
Uneven Cooling or Hot Spots
If some rooms feel like saunas while others are icy, it may be time for a system balance or filter change.
Higher Than Normal Energy Bills
An inefficient system works harder and uses more power. A quick AC tune-up service can get things running smoothly again.
Unusual Noises or Smells
Rattling, musty odors, or buzzing sounds can point to clogged filters, worn parts, or excess moisture—common issues resolved during routine AC maintenance.
Poor Airflow from Vents
If airflow has dropped off, your ducts or blower motor may need attention. Our team checks and clears blockages during your air conditioning maintenance service.
A Year Passed Since Your Last Tune-Up
Regular servicing is recommended. Ideally before summer to help prevent wear and tear and maximizes cooling performance.
To keep your system running at peak performance, we recommend scheduling an AC maintenance tune-up at least once a year. Ideally in early spring before the summer heat hits. Regular maintenance helps prevent unexpected breakdowns, improves energy efficiency, and extends the life of your system. If you have an older unit or use your AC heavily, twice-a-year checkups may be a smart move.
Our AC tune-up service covers everything from coil cleaning and refrigerant checks to filter replacement, thermostat calibration, and safety inspections.
Yes! Our AC tune-up service is designed to be thorough and preventative, not just a quick once-over. We have seasonal tune-ups, priority scheduling, and discounts on future repairs. Get in touch with A-One to know your options.
