A central air conditioner and a heat pump can look very similar from the outside, and both cool your house in summer. The big difference is that a heat pump can also heat the home by reversing how it moves heat.

If your house feels sticky even though the air conditioner is running, you are not imagining it. Comfort depends on controlling both temperature and humidity.

This is one of the most important replacement questions a homeowner can ask. And the answer is not just based on square footage.

If your AC seems to run nonstop during a Texas summer, some long cycles may be normal. But if comfort drops, airflow feels weak, or bills rise, it may point to a real issue.
