Switching From AC to Heat in Franklin Park, NJ
Switch from AC to heat safely this fall with simple thermostat, filter, and vent checks, plus warning signs that mean it is time to call an HVAC professional.
Fall in Franklin Park, NJ, is a good time to check your heating system before you need it every day. Switching from AC to heat is usually straightforward, but a few simple checks can help you catch problems and avoid unnecessary strain on your equipment.
Start With the Thermostat and a Short Heating Test
Choose a mild day when you can stay home for the first heating test. Set the thermostat to Off and let the cooling cycle finish before selecting Heat; follow any changeover instructions in your thermostat manual. Set the temperature a few degrees above the room temperature and leave the fan on Auto. Give the system time to start, since built-in delays are normal, and avoid repeatedly switching modes or raising the setting. Check that the room begins warming. If you have a heat pump, its airflow may feel less hot than a furnace’s. Do not select Emergency Heat for routine seasonal startup.
Check the Filter, Airflow, and Outdoor Equipment
With the system turned off, inspect the air filter if your equipment uses one. Replace a disposable filter when dirty, using the correct size and a type approved for your system; follow the manufacturer’s instructions for reusable filters. Keep supply vents and return grilles open and clear of rugs, curtains, and furniture. If your home has radiators or baseboard heat, keep their heat-emitting surfaces unobstructed instead. Outside, remove loose leaves around equipment without opening panels or reaching inside. A heat pump needs its outdoor unit throughout the heating season, so never cover it while it operates. Avoid wrapping an AC-only unit unless its manufacturer specifically recommends a suitable cover.
Know Which Startup Signs Need Immediate Attention
A faint dusty smell can occur when heat first runs after months of disuse, but it should fade quickly. Persistent burning odors, smoke, soot, grinding, or repeated shutdowns are not normal; stop using the system and arrange professional service. If you see fire or heavy smoke, leave and call 911. If you smell gas, leave immediately without touching the thermostat, electrical switches, or phones inside. Call your gas utility’s emergency line or 911 from outside. If a carbon monoxide alarm sounds, get everyone outdoors and call 911. Before heating season, test smoke and carbon monoxide alarms according to their instructions and check their replacement dates.
Schedule Service Before Small Problems Become Bigger
If the heat does not start, check the thermostat mode, setting, and batteries if applicable. Confirm that an accessible service switch has not been accidentally turned off, but do not open equipment panels or repeatedly reset a tripped breaker. Call a professional for persistent cold airflow, uneven heating that does not improve after clearing vents, frequent cycling, or unusual noises. Seasonal maintenance can include checking safety controls, electrical components, and, where applicable, burners and venting. Boilers and heat pumps need equipment-specific checks too.
