How often should I service my AC in Central Texas?
Check or change standard filters about monthly during heavy use, and schedule professional maintenance twice a year: in spring before cooling season and in fall before heating season.
Should I repair or replace my air conditioner?
If your system needs frequent repairs, is getting older, or a repair costs a large share of a new system, replacement is often the better value. Ellis can inspect your system and give you both options.
Do you offer financing or discounts?
Yes. Financing for new systems is available through Regions and Microf. Military and first-responder discount: 5% off full system replacements plus 10% off repair parts (labor not included). Can’t be combined with Cool Club.
