Heating calls in Armour
Across 1 ZIP codes in Armour, the heating calls that come through split roughly between no heat at all and not enough heat. The second is harder to diagnose and more often turns out to be airflow or duct losses rather than the heat source.

Local considerations
Boiler systems in older Armour 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.
Pipe insulation in Armour is most valuable in runs that travel through unconditioned space: crawlspaces, unheated garages and exterior wall cavities. Those runs freeze first and they freeze fast when the heat source fails.

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.

- AC not cooling
What to do while you wait
- Switch the thermostat off so the system stops attempting ignition over and over.
- Confirm the gas supply valve is open and that a service switch has not been knocked off.
- Check the filter. A blocked one makes the furnace overheat and shut itself down.
- Keep interior doors open so the warmth remaining in the house distributes evenly.

Call (855) 321-3194Questions
Armour HVAC questions
Is a cracked heat exchanger repairable?
No. A cracked heat exchanger is a carbon monoxide risk rather than a comfort fault, and the correct response is replacement of the furnace. Any provider suggesting a patch on one is giving you poor advice.
Can I run a space heater meanwhile?
Portable heaters carry their own fire risk and should never be left running unattended or near fabric. Never use a gas range or an outdoor appliance to heat a room, which is a direct carbon monoxide hazard.
Do I need a carbon monoxide alarm?
If any gas appliance runs in the home, yes. Carbon monoxide is colourless and odourless, and a working alarm near sleeping areas is the only reliable warning. If one sounds, leave the building and call 911 from outside.
Do you work on boilers in Armour?
Yes, where a provider covering your ZIP code handles them. Boiler faults run to pressure loss, circulator pumps, expansion tanks and zone valves, which is a different skill set from forced-air work. Say so when you call.
Why does my furnace smell when it first runs?
A brief dusty smell on the first run of the season is normal as dust burns off the heat exchanger. A persistent burning smell, or any electrical smell, is not. Shut it off and call.
