We homeowners often pride ourselves in being handy; we tinker with cars, fix leaky faucets, and repair fences — and most of the time it’s a quick fix and the need to call a professional is null and void. If you’re having central air conditioning issues, there are a few DIY troubleshooting tips that you can follow before you contact our professional HVAC company to make a repair.
This troubleshooting guide is for those who notice that no air is coming out of the floor or ceiling registers.
- First things first, if you notice no air coming from your vents, go outside to the unit and check to see if the fan is on. If you find the fan isn’t on, be sure to check the breakers on the furnace/AC unit. Having a breaker turn off is a common issue that can be easily resolved with a flick of a switch.
- After heading to the breaker on your central air conditioning unit and you find that it’s still on, there might be an issue with your thermostat. Head back inside to the thermostat and replace the batteries. If this does not solve the problem, it could be an issue with the air handler control board or a wiring issue between the board and the thermostat.
- Depending on the year and model of your central AC system, your unit may have a condensate pump. This pump leads to a reservoir which can eventually become full and will turn off due to a limit switch. If this is the case, you will need to replace your pump.
- One of the most common issues with a central air conditioning unit that hasn’t been maintained properly is the breaker trips. Try to reset the breaker by turning it off then turning it back on again. If the unit doesn’t turn on or turns on only briefly, there could be a problem with the wiring and you will need to contact a professional for AC repair services.
These troubleshooting tips are enough to get you started to solving your central air conditioning issues, but we strongly recommend contacting our professional HVAC company if you’re not sure what to do. One of our service reps will come out and walk you through the repair process.
