Local considerations
Carbon monoxide risk applies to any combustion appliance in a Fenton home. A working alarm near sleeping areas is the only reliable warning, and a sounding alarm means leaving the building before calling anyone.
Heating equipment replacement in Fenton normally needs a permit from the local building department, and venting is usually the part that gets inspected. The provider typically handles the permit as part of the job.

Ice on the outdoor unit in heating mode is expected briefly during defrost, but continuous icing means the defrost cycle has failed.
Details

Pressure that drops overnight means there is a leak somewhere in the loop, and finding it before the pipes freeze is a different category of urgency than a summer repair.

Fenton HVAC questions
Can someone come out tonight?
The line is answered 24/7 in ET. Whether a provider can reach Fenton overnight depends on participation, technician availability and demand, which spikes during cold snaps. The operator tells you the realistic window rather than guessing.
Is there a charge to call?
No. There is no charge to call and no obligation to proceed. We may be compensated by providers or partners when you call, which does not affect what you pay. The provider quotes their own price before any work starts.
What heating systems do you cover in Fenton?
Gas and electric furnaces, boilers, heat pumps running in heating mode, and the controls that operate them. Mention which you have when you call, because combustion work and refrigerant-cycle work need different parts on the truck.
Why is my heat pump running constantly?
A heat pump that never cycles off is usually low on charge, iced on the outdoor coil, or leaning on auxiliary resistance heat because the reversing valve is not completing the switch into heating mode.
Do I have to be home?
Yes. The technician needs access to the thermostat and the equipment itself, and someone has to approve the quoted price before work begins. For combustion appliances they may also want to check alarms.
