AC Not Blowing Cold Air

The most obvious sign is the fact that your AC is not blowing cold enough air. This can be caused by a number of things. Common situations we find are clogged filters, thermostat issues or build up in your condenser.

I Have Hot Spots In My House

Some areas of your home are naturally warmer than others. If a room is not cooling the way it use to, you might have ventilation issues. It would be best to have your ventilation inspected for optimal air flow.

My AC Keeps Freezing

A freezing air conditioner could be caused by poor airflow or low refrigerant. Poor airflow is often caused by dirty filters or a dirty coil. Replacing your filters and cleaning the coil regularly are required maintenance tasks. Low refrigerant could be a sign of a leak. Be sure to have this inspected by one of our trained technicians.

Water Coming Out of My AC

If you have water leaking inside your home, the condensation is not draining properly from your evaporator coil. This water will continue to leak as your AC runs. You will need to have this repaired quickly to prevent extensive water damage.

Cost To Run AC Is Increasing Each Month

If the cost to run your AC keep going up, then the efficiency of your system has been compromised. Having a well maintained air conditioner will increase its efficiency to cool and by doing so will lower your monthly cost to operate.
