How Regular HVAC Servicing Protects Your Family From Carbon Monoxide in Tucson Winters

07 Nov How Regular HVAC Servicing Protects Your Family From Carbon Monoxide in Tucson Winters

When Tucson experiences chilly winter mornings, your gas furnace turns on to keep your home warm and comfortable. But along with heat, every combustion process produces trace amounts of carbon monoxide (CO), an odorless, colorless gas that is dangerous to inhale. Normally, a properly functioning furnace vents this byproduct safely outdoors. But when systems are neglected, cracks, blockages, or faulty controls can allow CO to leak into your living space. In desert regions that dip into the 40s or lower, furnace safety is essential. Temco AC Repair & Replacement explains how to stay safe.

Ignition Control Inspections: Your First Line of Defense

One of the first points of failure that servicing catches is ignition control. The ignition system is responsible for lighting gas at precisely the right moment. When ignition is delayed or inconsistent, gas can build up before it catches fire, pushing combustion gases, and potentially carbon monoxide, through cracks or weak venting. Our HVAC contractors will test the igniter, flame sensor, and safety circuits to ensure reliable ignition timing, especially when cold start conditions place extra strain on the system.

Flue and Vent Work: Ensuring Safe Exhaust

The flue and venting system carry combustion gases out of your home. In desert climates, dust, debris, bird nests, or even sagging vent pipes can obstruct that pathway. When exhaust cannot escape freely, CO can back-draft into the home instead. Servicing includes a full inspection of your flue, vent joints, connections, and clearances. Any signs of corrosion, misalignment, or obstruction are corrected before they turn into hazards.

Heat Exchanger Integrity: Why Cracks Matter

The heat exchanger is the metal barrier between the burning gas and the air circulating through your home. Cracks or fractures threaten both performance and safety. If combustion gases cross over into the conditioned air stream, that’s a direct route for carbon monoxide. During routine servicing, our heating company will send technicians to visually inspect the exchanger, listen for unusual sounds, measure differential pressures, and sometimes use gas-leak detection tools. Any damage typically leads to replacement, not repair, because homeowner safety is paramount.
