Houses in Green Valley and in SaddleBrooke are often empty for months. The equipment still sat in dust, and the thermostat batteries may be dead. Start with Heat, not Emergency. Put the setpoint a few degrees above the room and listen for the furnace or the outdoor unit. The same pass is written as a list on the printable checklist and as an evening-before check on the first cold night.
Change the filter or at least look at it before a long heating cycle. A filter loaded in June will trip a furnace limit in November. If the outdoor disconnect or the breaker was opened when you left, close it before you decide the system is dead. One breaker reset is enough. If it trips again, leave it off.
A rotten-egg smell means leave and call 911 or Southwest Gas, even if you just walked in the door. Do not use switches. A tune-up after the system proves it will run is heating tune-up. We do not publish a membership price. SaddleBrooke street addresses are often 85739, which the form accepts. SaddleBrooke Ranch and Oracle are often 85623, and that ZIP is outside the list this form accepts right now. The Oracle page says so plainly.
An empty house can also come back to a dry faucet or a wet ceiling if a pipe froze while you were gone. That is not a furnace symptom. Shut the main water off if it is leaking, then read frozen pipes in Tucson. The water heater, if it was off or leaking, is water heater repair.
Startup checks
A sorting list. A system that will not start is a repair visit, not another pass through the checklist.
| Check | Why it matters after a long vacancy | If it fails |
|---|---|---|
| Thermostat on Heat, setpoint above the room | Emergency or Cool may have been left from the day you locked up | Nothing runs until the mode is actually Heat. |
| Filter | A summer of dust will choke the first heating call | Replace a packed filter. If the furnace still shuts off, it is a repair. |
| Batteries and the display | A blank thermostat looks like a dead furnace | Replace the batteries before you condemn the equipment. |
| Outdoor disconnect and breaker | People open them when they leave | One reset. A second trip means leave it off. |
| Smell at the first fire | Dust can smell. Gas is not dust. | Rotten eggs: leave, no switches, call 911 or Southwest Gas. |
Name, mobile phone, and ZIP are required. Street address can wait. We follow up the same business day by phone or email. That is a callback, not a promise of a repair the same day.
