Local considerations

A cracked heat exchanger ends the repair conversation in Saint Petersburg as anywhere else. It is a carbon monoxide risk rather than a comfort issue, and the correct response is replacement rather than patching.

Boiler systems in older Saint Petersburg homes frequently carry mineral scale inside the heat exchanger, degrading efficiency without a fault code. A descaling visit addresses it before the efficiency loss becomes a comfort complaint.

What is your thermostat reading?

Drag the dial to the temperature your thermostat shows now. The readout names the likely cause band, how urgent it is, and which page to read next.

Degrees F

Indoor temperature

Likely cause band: Cooling capacity loss: dirty coil, low refrigerant charge from a leak, or a failing capacitor.
Urgency: Call today
Read next: AC not cooling

Thermostat reading against likely cause. JavaScript is off, so the dial is shown as a table.
Reading	Likely cause	Urgency
60 F	The heating side is not producing heat at all. Ignition lockout, a dirty flame sensor or a tripped limit switch.	Call now
62 F	The burner is lighting then dropping out, or the blower is running without heat behind it.	Call now
64 F	A heat pump that is not completing the switch into heating mode, or one stuck relying on auxiliary resistance heat.	Call now
66 F	Heat is being produced but not distributed. Airflow restriction, duct losses or a zoning fault.	Call today
68 F	Close to a normal winter setpoint. If the room feels colder than this reading, suspect the thermostat itself.	Call today
70 F	Within the normal comfort band. Nothing here points at a fault on its own.	Monitor
72 F	Within the normal comfort band. Worth noting how long the system runs to hold this figure.	Monitor
74 F	Slightly above a typical cooling setpoint. If the system cycles on and off rapidly, that is the fault to chase.	Monitor
76 F	The system is falling behind setpoint. Airflow restriction or a coil that cannot absorb heat.	Call today
78 F	Cooling capacity loss: dirty coil, low refrigerant charge from a leak, or a failing capacitor.	Call today
80 F	Supply air is close to room temperature. The refrigerant side or the compressor is not contributing.	Call today
82 F	Well above setpoint with the system running. Check for ice on the indoor coil or the line set.	Call now
84 F	Substantial capacity loss. A leak that has been developing across the season is the usual finding.	Call now
86 F	The system is effectively not cooling. Check whether the outdoor unit is running at all or tripping its breaker.	Call now
88 F	Indoor temperature is approaching outdoor temperature, which means no useful cooling is happening.	Call now
90 F	A health risk in a heat event. Move anyone vulnerable to a cooler space and treat this as urgent.	Call now

What to do while you wait

Set the system to off instead of raising the setpoint, which will not force it to run.
Check whether the outdoor unit on a heat pump is iced over, and do not chip at it.
Look at the filter and replace it if light will not pass through.
Never heat a room with a gas range or an outdoor appliance. That is a carbon monoxide risk.

Questions

Saint Petersburg HVAC questions

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.

What does heating repair cost in Saint Petersburg?

We do not quote prices. The provider who attends confirms the price on site before work begins. Boiler and heat pump work generally takes longer to diagnose than a straightforward furnace fault.

What should I do before the provider arrives?

Set the thermostat to off rather than leaving it calling for heat against a locked-out system, replace a loaded filter, and close off unused rooms. Keep anyone vulnerable in the warmest part of the house.

What if my furnace is still under warranty?

Parts warranties of five to ten years are common, labor warranties are not. Have the model and serial number ready when you call so the provider can check coverage before fitting anything.
