System Failure in 100°+ Weather: Most breakdowns happen during peak usage because of worn-out capacitors or dirty coils.
Voiding Your Warranty: Manufacturers often require proof of professional air conditioner maintenance to honor parts warranties.
Energy Inefficiency: A dirty system works 20–30% harder, leading to the “massive electric bill” shock many Katy homeowners face.

Standard air conditioner maintenance in Katy typically ranges from $100 to $200 for a single-system tune-up. While basic inspections are affordable, the “real” cost of a service visit depends on whether repairs (like a capacitor or fan motor) are needed. At 24 Seven AC, we offer transparent pricing and 0% APR financing for any necessary repairs found during your visit.
The $5000 AC Rule is a professional guideline to help you decide between repair and replacement. You multiply the age of the unit by the cost of the repair. If the total exceeds $5,000, it is generally more cost-effective to replace the system with a new, high-efficiency unit.
Example: A 12-year-old unit needing a $600 repair (12 x 600 = 7,200). In this case, our AC Installation & Replacement experts would recommend an upgrade.
Due to Katy’s extreme humidity and long cooling season, your AC should be serviced twice per year. A spring visit ensures your cooling is ready for summer, and a fall visit prepares your heating system for the winter.
