Check the ThermostatThe thermostat should be on the correct setting for the temperature and the season. After you check the thermostat's wiring, you need to confirm that the thermostat is sending an "on" signal, which one of our trained HVAC technicians can help you determine. Inspect Electrical ComponentsIf a component is malfunctioning, it may cause the heat pump to not turn on. Make sure the circuit panels have not been tripped, inspect the sub panels that supply power to the heat pump, and examine your main electrical panel. Or, you can take advantage of our premier heating services and have a heating system expert take a look at it all for you! Each certified member of our team is well-versed in system diagnosis, system replacement, and heating repair. Identify Other IssuesSome signs of the problem include humming noises, leaking, and irregular functioning. For example, if you can turn on the heat pump, but it shuts off after a short time, this may be a sign that a significant component isn't working correctly. If it's time to replace your system, we can perform a new heater installation. For more information about our heating services, contact Drew's Crew Heating & Air today!
