Things to Check Before Scheduling a Service Call

Before calling for service, there are a few simple thermostat checks that could get your AC back up and running:

1. Make sure it's set to "Cool" mode, not "Heat". It's an easy mistake to make.

2. If the display is blank, replace the thermostat batteries. Many run on batteries that can drain over time.

3. Check that the temperature is set below the room's current temp. The system won't kick on to cool if the desired temperature has been reached.

4. Look for any error codes or messages on the display and consult your manual. Newer thermostats provide diagnostic info.

Your thermostat acts as the brain for your system. A simple setting issue or low batteries could be all that's preventing your AC from working properly. Running through these basic checks can potentially avoid an unnecessary service call charge.

If adjusting the thermostat doesn't get the cool air flowing, please let us know! Our technicians will be happy to fully diagnose the issue and get you comfortable again quickly.

If your thermostat is working, and your unit still isn’t, check the circuit breaker or fuse box. Many homeowners do this automatically anyway, but it’s still an important and helpful step. Unexpected power surges and outages can burn out or trip your system’s fuse, cutting off power to the unit and leaving you with an uncomfortably hot home. This is another quick solution that may save you a lot of hassle.

Clogged air filters are a common culprit behind AC troubles. They restrict airflow, forcing your system to work harder to cool your home. This unnecessary strain increases energy costs and can lead to premature system breakdowns.

If you notice weak or no airflow from your vents, or see ice buildup on the refrigerant lines, a dirty filter could be the issue. Checking and changing filters regularly is an easy way to keep your AC running at peak efficiency.

For most households, filters should be replaced every 30-90 days during periods of heavy usage. Consider marking your calendar as a reminder. Regularly swapping out clogged filters promotes proper airflow and can:

1. Reduce energy consumption and utility costs
2. Prevent costly repair bills down the road
3. Improve indoor air quality and comfort

While you're checking filters, make sure your return air vents aren't blocked by furniture or other obstructions. Keeping airflow pathways clear allows your system to "breathe" properly.

Taking just a few minutes to inspect and change filters is a simple preventative maintenance step that can save you money and hassle in the long run. If replacing yours doesn't restore airflow, let us know - additional diagnostics may be needed.

Both the indoor and outdoor portions of your HVAC system have power switches or disconnects that can sometimes get inadvertently flipped to the "off" position. This simple mistake could be why your AC isn't turning on.

Before calling for service, quickly check:

The indoor air handler/furnace cabinet - Look for a switch or lever, likely located within easy reach.

The outdoor condensing unit - There should be an exterior switch or pullbox mounted to the unit or nearby.

Kids playing near the equipment or exterior work being done are common culprits behind accidental switch flips. But regardless of the cause, getting those switches back to the "on" position may be all it takes to restore cooling power.

However, we recommend leaving any enclosed panels or covers alone. Attempting to remove them could expose dangerous electrical components best serviced by a professional.

If verifying both the indoor and outdoor disconnects are turned on doesn't get your system running, there could be a more complex issue at hand. Feel free to give us a call, and we'll be happy to properly diagnose and resolve the problem.

Taking a few seconds to inspect these power switches is an easy troubleshooting step worth checking off the list. A simple flip could have your AC up and running again quickly without the need for a service call.

Your air conditioner's drain line is connected to an emergency cutoff or float switch that shuts off the condenser coil if a blockage occurs, stopping further condensation and potential water buildup.
If you notice your unit isn't running despite the thermostat being on and the unit having power, a clogged drain line could be the problem.
Inspect the drain pan and line for any standing water, and try to clear the blockage carefully by flushing the drain line.
Keeping the drain line free of obstructions will make sure your AC can function properly and also prevent water damage.

While these troubleshooting tips may help resolve common AC issues, we understand that some problems require professional expertise. If you've tried these steps and your air conditioning system still isn't working properly, don't hesitate to contact Pat at AC Repair San Ramon (925) 884-0209 or use our convenient contact form to schedule a service appointment.
