Q2. How often should I have my AC unit serviced?

Q3. What are the signs that my AC unit needs repair?
A: Common signs that your AC unit needs repair include unusual noises, strange odors, poor airflow, frequent cycling on and off, leaks around the unit, and higher-than-usual energy bills. If you notice any of these signs, it's best to contact a professional for an inspection.
Q4. Can I perform AC repairs myself?
A: While some minor maintenance tasks like changing the air filter can be done by homeowners, most AC repairs should be handled by a licensed technician. Attempting to fix the unit yourself can be dangerous and may void your warranty.

Yes. Annual maintenance helps keep your system efficient, reliable, and operating within manufacturer guidelines, especially in Plano’s demanding climate.
Maintenance can’t prevent all repairs, but it significantly reduces the risk of major breakdowns by catching small issues early.
A clean, well-adjusted system operates more efficiently, which often results in lower energy usage and reduced utility costs.
Over time, neglected systems lose efficiency, require more repairs, and tend to fail earlier than well-maintained units.
Basic tasks like filter changes are helpful, but professional maintenance includes inspections and adjustments that homeowners can’t safely or effectively perform on their own.
