Tell us where the equipment is. A package unit on a pad next to a manufactured home, a unit on the roof, and a split system with a closet furnace are three different access jobs. The ducts are often short and in the belly of the home. A room that never heats can be a crushed belly duct or a disconnected collar, which is ductwork, not automatically a bad furnace.
Heat is still either gas or a heat pump. A gas furnace that will not light is furnace not turning on. A heat pump blowing cold air is that page. Some homes still use an evaporative cooler for summer. That repair is swamp cooler repair, and it is not a refrigerant job. We are not publishing a mobile-home equipment price, and we are not naming a license class on this page.
Put the ZIP on the form. Tucson Estates addresses are commonly 85735. Picture Rocks is commonly 85743. Those communities are not the same drive, and a neighborhood name without the ZIP is how the wrong page gets used.
Symptoms and how they’re checked
No price column.
| Symptom | Likely cause | How it’s checked |
|---|---|---|
| One room is cold, the furnace runs | Belly duct, a disconnected collar, or a closed register | The duct path under the home, not a new furnace by default. |
| The package unit is silent | Breaker, disconnect at the unit, or the control circuit | One breaker reset. The disconnect at the unit is easy to leave off. |
| Gas heat will not light | Same ignition sequence as any furnace | Inducer, glow, flame. A gas smell means leave and call 911 or Southwest Gas. |
| Heat pump air feels cold | Mode, defrost, or the outdoor section of the package unit | Whether the outdoor fan runs in heat. The cold-air page covers the sequence. |
| Summer cooling is a swamp cooler | Pump, pads, or the float, not refrigerant | The swamp-cooler page. Do not add refrigerant to an evaporative cooler. |
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.
