Is Your AC Acting Up? Watch Out For These Signs
When you need AC service, the system usually gives you some warning. Watch for the following symptoms and call Cold Factor before they get worse:
- Indoor temperatures don't match the thermostat setting (rooms feel warmer than the display reads)
- Sudden spikes in your cooling bill, especially during normal usage months
- Strange noises from the unit such as banging, rattling or a high-pitched whistle
- The system won't power on, or it cycles off too quickly to cool your home
- Warm or weak air blowing from your vents
- Visible water pooling around the indoor unit (clogged condensate drain line)
- Musty or burning smells when the system runs

Can My AC Unit Be Repaired?
There are a lot of other HVAC companies that will try to sell you an entirely new unit instead of actually seeing if your unit can be saved. While there are certain circumstances that would mean your system would need to be replaced, not every situation is the same and in some cases yes, your unit can be repaired.
However, if your system is on the older side and it’s broken down many times already, the best bet will be to install a new system. Depending on the situation, your technician can walk you through all of the options and give you an honest evaluation to see which option works best for you, your budget, and your air conditioning unit.
AC Repair Options
Most AC repair calls fall into a familiar handful of symptoms. Weak airflow, warm air from the vents and water around the indoor unit are the three issues we see most often in Flower Mound and Roanoke homes.
Cold Factor's technicians diagnose the actual cause before quoting work, and we won't recommend a full replacement when a repair will fix the problem.

FAQs
FAQs About Our AC Repair and Maintenance Solutions
How often should AC maintenance be performed in North Texas?
For most Flower Mound and Roanoke homes, professional AC maintenance once a year in spring is enough to catch problems before the cooling season starts. Older systems and homes with heavy AC use benefit from a second visit in late summer. Filters should be checked monthly and replaced every 60 to 90 days between visits.
What is included in a professional AC maintenance visit?
A professional AC maintenance visit covers far more than a filter swap. Technicians clean both sets of coils, then check refrigerant pressure and flush the condensate drain. Electrical components get a load test, and the thermostat is calibrated. Most visits take about an hour for a residential system.
What are the benefits of regular AC maintenance?
Annual maintenance lowers your monthly cooling bill by keeping the system running at full efficiency. It extends the lifespan of the unit by reducing wear on the compressor and other major components. Most manufacturer warranties also require proof of annual professional maintenance to stay valid.
When is the best time to schedule AC maintenance?
Spring is the best time to schedule AC maintenance in North Texas, before the system gets hammered by 100°F summer heat. Scheduling early also avoids the peak-season backlog when same-day visits get harder to book. Mid-summer scheduling is still better than skipping the visit entirely.
