If your air conditioner is running but the air coming out of the vents feels warm, weak, or just not cold enough, it usually means the system is not removing heat correctly, not moving air correctly, or both.

Yes, your HVAC system can absolutely help with indoor air quality. But it is only part of the picture.

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.
