HVAC Repair: Before You Call a Professional

Before you call a professional for HVAC repair, there are a few preliminary items you can check to ensure your HVAC system does actually need service. Checking these items before calling saves you valuable time and money.

HVAC Repair

Check the Power

Go to your electrical panel to ensure a fuse has not blown, or that power is properly switched on to the AC unit.

Check the Air Filter

If your AC is not working properly, it could be remedied by a simple filter change. It is recommended that air filters are changed at least once every three months to ensure maximum air flow and quality.

Check the Thermostat

It may sound silly, but small oversights like this can be the cause of AC issues. Make sure your thermostat is set to cool and is at least three degrees below the current room temperature. In addition to checking the temperature – remove the thermostat cover to check the internals. Are there batteries that need replacing? Are the wires firmly connected?

Clean the Condensate Drain

As the HVAC system conditions the air, it creates water by removing moisture from the air. They then typically deposit this water through a plastic drain pipe. Over a period of time, this pipe can be blocked by different materials or even algae. If left unchecked, this blockage can lead to water back-ups.

Brinson and Sons encourages its customers to troubleshoot before calling. However, we do recommend that you only perform steps you feel completely comfortable with in order to avoid additional damage to your HVAC system. To learn more about our AC services, check out our Air Conditioning page.
