Switching From AC to Heat This Fall in Bloomfield, NJ
Switch from AC to heat safely this fall in Bloomfield, NJ, with simple thermostat, filter, and vent checks, plus warning signs that mean it is time to call.
The first cool days of fall are a good time to check your heating system before you need it every night. A few simple checks can make the switch from cooling to heating smoother and help you catch problems before colder weather settles in.
Start With the Thermostat
Choose a mild day when you can stay home for a short heating test. Let any active cooling cycle finish, switch the thermostat to Off, and follow your equipment instructions for the waiting period before selecting Heat. Avoid repeatedly switching between cooling and heating. Set the temperature a few degrees above the room temperature and, for forced-air systems, set the fan to Auto so it runs with normal heating operation. Check thermostat batteries if applicable, and review schedules that may still reflect summer settings. Give the system time to respond; built-in delays are normal. If you have a heat pump, do not select Emergency Heat for a routine seasonal change.
Check Filters, Vents, and the Area Around Equipment
For a furnace or ducted heat pump, turn the system off before checking the air filter. Replace a dirty disposable filter with the size and type recommended for your equipment, following the airflow arrow. Do not assume a more restrictive filter is better; it can reduce airflow if the system is not designed for it. Keep supply registers and return grilles open and clear of furniture, rugs, and curtains. For boilers, keep radiators or baseboards clear instead. Remove stored items from around heating equipment, especially flammable materials. From ground level, check accessible outdoor intake and exhaust openings for leaves or obvious blockage. Leave equipment disassembly, internal cleaning, and unfamiliar obstructions to a professional.
Run a Short Test and Watch for Warning Signs
During the test, check whether the indoor temperature begins rising and listen for unusual sounds. Heat pumps often deliver air that feels less hot than furnace air, and radiators may take time to warm. A faint dusty smell can occur at the first startup, but it should fade quickly. Stop the system and call for service if you notice a persistent burning odor, repeated shutdowns, loud banging, or no heat after checking the thermostat settings. Smoke or a strong electrical burning smell calls for immediate attention; leave and call emergency services if there is a fire concern. Do not keep restarting equipment that shuts itself down, and never bypass a safety switch.
Check Safety Devices and Arrange Fall Maintenance
Test smoke and carbon monoxide alarms according to their instructions, and replace batteries or expired devices as needed. Carbon monoxide has no smell. If a CO alarm sounds, get everyone outside and call 911 from a safe location; do not reenter until responders say it is safe. If you smell gas, leave without operating switches, thermostats, or phones inside, then call your gas utility’s emergency line or 911 from outside. Seasonal maintenance gives a technician a chance to inspect heating operation and safety components beyond homeowner checks.
