My Heat Works but Not AC — Is This an Emergency in Elk City?

If your heat works but not your AC, yes—this can still be an HVAC emergency, especially if the system is short-cycling, freezing up, or stressing shared components.

In Elk City, we see this issue most often during seasonal changeovers.

Why This Happens (And Why It’s Risky)

When homeowners say “my heat works but not AC,” the usual culprits are:

• Failing reversing valve (heat pumps)
• Bad capacitor shared by heat & AC
• Control board or thermostat miscommunication
• Frozen evaporator coil damaging the compressor

Running the system in this state can:

• Burn out the compressor
• Cause electrical damage
• Leave you without both heat and AC

When This Becomes an Emergency

Call immediately if:

• The outdoor unit is buzzing or clicking
• Ice forms on refrigerant lines
• The system shuts off repeatedly
• You smell electrical or burning odors
