Excellent customer services, high quality work for a fair price and the company has ethics. Family owned & operated for 15 years, this is not a corporate company. Lots of HVAC companies in the area so do your research when choosing a company and support local.

Nelson Rivas was SO helpful and very friendly. Would recommend him to anyone having issues with their AC. Hopefully I don’t have any problems in the future, but if I do, he will be the first person I call! :-)

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.
Air Conditioning Service 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.
How We Approach AIR CONDITIONING Repair
- Honest diagnosis before any work starts - ask about AC repair cost and get a written estimate you approve in advance
- No pressure to replace a system that can be repaired
- Transparent communication so you know exactly what is happening and why
- Central AC repair and routine tune-ups, backed by the same workmanship guarantee
- Diagnosis and repair for major components, including compressors, capacitors, and refrigerant leaks
What You Get When Cold Factor Handles the Repair

What's Included in Professional AC Maintenance
A professional AC maintenance visit is a full system check, not just a filter swap. Cold Factor’s technicians follow a detailed checklist on every visit so nothing slips through.
Pair maintenance with our HVAC maintenance plan to lock in priority scheduling and discounted service rates.
- Filter inspection and replacement to keep airflow strong and protect the rest of the system
- Evaporator and condenser coil cleaning to restore heat transfer
- Refrigerant level check with leak detection and recharge if low
- Condensate drain line flush to prevent water damage and indoor humidity issues
- Capacitor and contactor inspection plus a check for loose or corroded wiring
- Thermostat calibration check to make sure the system is reading temperature correctly
- Blower motor and fan inspection for safe, balanced operation

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.
