To know whether your HVAC system is working properly or not, you must create a checklist of things that create problems. First, check your air filter and ensure they are clean and working properly.
Secondly, check the circuit breaker that usually shuts off your system in case of high voltage.
Third, monitor your thermostat and keep it to the desired temperature and time and make note of any lapses or excessive running of the fan.
Lastly, take visual observations of the fan and compressor and see if there’s any sign of damage. If all these things are good to go and your HVAC is cooling properly, just sit back and enjoy!
