Your central AC won’t turn on?

If you’re not able to turn on your AC instantly, even after the thermostat indicates the requirement for cooling. Consider taking a look on the main electric and the secondary panels of the circuits for a fallen breaker or fused circuit. If you see that there is a problem, retune the wave by turning it off and then turning it on again, or substituting the fuse. A central AC can be connected to a steadfast circuit of 240 volt.

If the wave keeps tripping, consider a shortage in the machine, either in the capacitor compressor, or motor. For the best results, get a central AC repair professional to navigate through the problem and solve it.

Is your thermostat placed on the right setting?

If you have a smart automated thermostat, you can more easily manage the temperature in your home, so that it provides you comfort when you’re there and gives you warmth when you’re not. However, if you find your thermostat is not working correctly, it may not be able to convey your AC to turn on.

It’s likely time to contact your HVAC repair professionals, who will fix or replace the thermostat.

The old and dial type thermostat is more prone to calibration issues, but sometimes the new programmable thermostats are not that easy to operate. So, while doing central AC troubleshooting, consult your thermostat manual to ensure you have set your thermostat accurately.

Are your registers clogged and dirty?

If you have a blocked air heating and cooling system, it is important to clean the registers to remove all the build-up dust. Ensure that the furniture and other objects are not blocking the movement of air through the registers.

Are plantations overcrowding the compressor?

The outdoor compressor for central air needs sufficient air circulation to work appropriately. Thus, it is important to ensure that there’s at least a distance of 2to 3 feet from the compressor. There must be at least 5 feet of clearance distance in between the top unit and the trees above.

Is there a problem in the capacitor or the contactor?

Before, you make any decision, make sure whether the problem is in the capacitor or the contactor.

If you hear some clicking sound followed by humming or buzzing, it’s probably the fan motor attempting to start without any help from the capacitor. You can almost conclude that capacitor has stopped working. Sometimes, you may try to start the compressor by spinning the fan pushing it with a thin stick or a screwdriver poking it through the grille.

Chances could be good, but it would work only for one cycle and the capacitor is likely to fail the next time you switch on the AC. The best idea is to call the central AC repair servicemen and replace the capacitor.

If the compressor clicks when you switch on the thermostat, bit doesn’t make any humming or buzzing sound, it’s the contactor that’s needed to be replaced.

Do you have your Central AC checked annually?

Getting an inspection done by an HVAC professional can detect any serious problems before they worsen and leave you stressed with it. The professional will review all the moving parts, along with the refrigerant and replace the system if needed.
