San Marcos HVAC questions, answered
Do you offer maintenance plans?
We do. A two-visit plan in Texas covers a spring cooling inspection and an autumn heating inspection, priority scheduling during peak weeks, discounted repairs and no diagnostic fee. Members rarely end up on the emergency list.
What brands do you service in San Marcos?
All of them. Our 78666 technicians are trained on Carrier, Trane, Lennox, Rheem and essentially every other residential brand sold in Texas, including discontinued lines. We keep a broad parts catalogue on the trucks for exactly that reason.
Do you charge extra for nights, weekends or holidays?
No. Our pricing in Texas is the same at 2am on a holiday as it is at 2pm on a Tuesday. Emergency calls are dispatched the same way as scheduled calls and carry no overtime premium.
How often should I change my filter in 78666?
Monthly inspection and replacement every 60 to 90 days is the baseline. Homes in San Marcos with pets, ongoing construction nearby, or a high-MERV filter in an undersized return should move to monthly changes. A loaded filter is the single most common cause of frozen coils and failed blower motors.
Are your technicians licensed and insured?
Every technician dispatched into San Marcos is licensed, insured and background-checked. We can provide proof of insurance on request before the visit if you would like it on file.
