What’s Going On With Your AC?

Choose the problem that sounds most like your home, and we’ll show you where to start.

AC Not Cooling

If your AC is running but the air coming out of the vents feels warm or barely cool, something is wrong. It could be low refrigerant, a failing component, or a clogged coil that needs professional attention.

Recommended services:

  • AC repair visit and full system diagnosis
  • Filter and coil inspection / cleaning
  • AC maintenance to prevent repeat issues

AC runs all the time

When your AC never seems to shut off, it wastes energy and still doesn’t keep you comfortable. The cause might be low refrigerant levels, poor airflow, thermostat problems, or an incorrectly sized system for your home.

Recommended services:

  • AC repair and performance check
  • Thermostat and airflow inspection
  • System sizing and replacement consultation if needed

Hot and cold spots

If some rooms feel like a freezer and others never cool down, your system is not distributing air evenly. Duct issues, blocked vents, or an undersized system could be the cause of the uneven temperatures.

Recommended services:

  • AC diagnostic visit and airflow testing
  • Ductwork inspection and balancing
  • System sizing review and upgrade options
