Frequently Asked Questions
Got questions? We’ve got answers. If you don’t see your question here, just give us a call.
Do you really offer 24/7 emergency service?
Yes! AC emergencies don’t wait for business hours, and neither do we. Call us anytime, day or night, weekends or holidays, and we’ll dispatch a tech to get your comfort restored.
What areas do you serve?
We proudly serve New Braunfels, Gruene, Seguin, Schertz, Cibolo, Marion, Canyon Lake, and San Antonio (Comal & Guadalupe Counties). View our service areas page for more details.
Why does NATE-certified matter?
NATE (North American Technician Excellence) is the industry’s gold standard for technician certification. It means our techs have passed rigorous, knowledge-based exams and have real-world working knowledge of HVAC systems. You get it fixed right the first time.
Do you offer financing?
Yes, we offer promotional financing with approved credit through Synchrony. We believe everyone deserves a comfortable home, and we’ll work with you to find a payment plan that fits your budget.
What’s included in the Centeno Comfort Commitment maintenance plan?
You get two comprehensive tune-ups per year (Spring AC, Fall Heating), absolutely $0 trip/diagnostic fees, priority front-of-the-line scheduling, 15% off any repairs, and a free Indoor Air Quality assessment.
Will a new system really lower my energy bills?
Absolutely. Older systems often operate at 10 SEER or lower. Upgrading to a new, high-efficiency SEER2 system can cut your cooling costs significantly, often paying for itself over its lifespan.
