If your air conditioner is cooling but costing more than it should, an efficiency problem is at work. In Katy, where AC runs much of the year, lost efficiency adds up fast on your energy bills. TemperaturePro Katy-Cypress diagnoses what’s dragging down your system’s performance and restores efficient, cost-effective cooling.
Here’s what hurts AC efficiency and how we fix it.
What Reduces AC Efficiency
- Dirty coils and filters – Buildup forces the system to work harder for the same cooling.
- Low refrigerant – A leak reduces capacity and efficiency.
- Leaky ducts – Conditioned air lost into the attic means longer run times.
- Poor airflow – Restrictions make the system strain and run longer.
- Aging equipment – Older, lower-SEER systems are inherently less efficient.
- Neglected maintenance – Small issues compound into significant efficiency loss.
Efficiency, SEER, and Your Bills
Cooling efficiency is rated by SEER—the higher the number, the less energy used for the same cooling. But even a high-SEER system loses efficiency when coils are dirty, refrigerant is low, or ducts leak. Restoring efficiency through cleaning, repair, and duct sealing often lowers bills noticeably. For older systems, we’ll honestly discuss whether efficiency repairs or an upgrade make more sense. For related issues, see AC high energy bills and our duct repair services.
How We Restore Efficiency
We inspect coils, refrigerant, airflow, and ducts, correct what’s reducing performance, and verify the system runs efficiently. Explore our AC repair services and AC maintenance, the best way to keep efficiency high. The U.S. Department of Energy explains AC efficiency and SEER.

Frequently Asked Questions
Why is my AC suddenly less efficient?
Common causes include dirty coils or filters, low refrigerant, leaky ducts, poor airflow, or deferred maintenance—all of which make the system work harder.
What is SEER?
SEER (Seasonal Energy Efficiency Ratio) measures cooling efficiency. A higher SEER uses less energy for the same cooling, but real-world efficiency also depends on maintenance and ducts.
Can repairs improve my AC's efficiency?
Yes. Cleaning coils, fixing refrigerant leaks, and sealing ducts can restore lost efficiency and lower your bills, often significantly.
Should I repair for efficiency or replace my AC?
For newer systems, efficiency repairs make sense. For older, low-SEER units, an upgrade may save more long-term. We’ll give you an honest comparison.
