Switching From AC to Heat in Paterson, NJ This Fall
Get your home ready for fall heating with safe thermostat checks, filter tips, and warning signs to watch for before switching your system from AC to heat.
As fall temperatures cool in Paterson, switching from AC to heat is a good opportunity to check that your system is ready. A few simple steps can help you catch problems before you need steady heat, without opening equipment or handling electrical or gas components.
Start With the Thermostat, Not a Big Temperature Jump
Choose a mild day when you can stay home for the first heating cycle. Let any active cooling cycle finish, then select Off before changing the thermostat to Heat, following your equipment’s instructions for any required delay. Set the temperature a few degrees above the room temperature and keep the fan on Auto for normal operation. Raising the setting much higher will not heat the house faster and may trigger auxiliary heat on some heat pumps. Review your fall schedule and replace thermostat batteries if needed. A short startup delay can be normal, so avoid repeatedly switching modes or changing settings while you wait.
Check Airflow and Clear the Area Around Equipment
Before running the heat, inspect the air filter if your system uses one. Turn the system off before removing it, and replace a dirty disposable filter with the size and type recommended for your equipment. Follow the airflow arrow rather than guessing its direction. Keep supply registers and return grilles open and clear of furniture, rugs, and curtains. For boilers, make sure radiators or baseboard heaters are not blocked, and keep combustibles away according to manufacturer guidance. Clear stored items away from heating equipment. From ground level, look for leaves or debris obstructing accessible outdoor vent openings, but do not dismantle venting or insert tools into it.
Know What Is Normal—and What Requires Immediate Action
During the first heating run, a faint dusty smell may occur and should fade promptly. Persistent burning odors, visible smoke, or electrical smells are not normal; turn the system off if safe and get professional help. If you smell gas, leave immediately without using switches or phones inside, then call your gas utility’s emergency line or 911 from outside. If a carbon monoxide alarm sounds, get everyone outside and call 911. Test smoke and carbon monoxide alarms according to their instructions before heating season. Heat pump air may feel less hot than furnace air, but the indoor temperature should gradually move toward your thermostat setting.
Watch the First Cycle and Schedule Help When Needed
Let the system run through a normal cycle and check whether rooms begin warming. Call a professional if it repeatedly starts and stops, makes unusual banging or grinding sounds, blows cool air continuously in heating mode, or cannot reach the set temperature. If nothing starts, check thermostat settings, batteries, and whether the equipment’s service switch was accidentally turned off. Do not repeatedly reset a tripping breaker or troubleshoot burners yourself. A seasonal inspection can address ignition, controls, airflow, and venting as appropriate for your system.
