Switching From AC to Heat in Union City, NJ This Fall
Switch from AC to heat safely this fall with thermostat tips, filter checks, warning signs, and advice on when your heating system needs professional care.
Cooler fall weather in Union City is a good reminder to check your heating system before you need it every day. A few simple steps can help you switch from cooling to heating safely and catch problems before colder weather settles in.
Start With the Thermostat
Choose a cool day for your first heating test so you can comfortably check operation. If the AC is running, let it finish, switch the thermostat to Off, and follow your equipment’s instructions before selecting Heat. Avoid quickly switching back and forth; some systems have a built-in restart delay. Set the temperature a few degrees above the room temperature and choose Auto for the fan, if available. This generally runs the blower only when needed rather than continuously. Review your fall schedule and replace thermostat batteries if required. For heat pumps, use normal Heat mode, not Emergency Heat, unless your technician or equipment instructions direct otherwise.
Check Filters, Airflow, and Outdoor Equipment
Before testing a forced-air system, turn it off at the thermostat and inspect the air filter. Replace a dirty disposable filter with the correct size and type, following the airflow arrow; clean reusable filters only as directed by the manufacturer. Keep return grilles and supply registers open and free of furniture, rugs, and stored items. If you have radiators or baseboard heat, keep surrounding areas clear and follow required clearances. Outside, remove loose leaves around equipment without opening panels or reaching inside. A heat pump’s outdoor unit operates during heating, so never wrap or cover it while in use. Leave refrigerant lines, wiring, and internal cleaning to a professional.
Run a Short Test and Watch for Warning Signs
Let the heat run long enough to confirm that the indoor temperature begins rising. Heat-pump air may feel less hot than furnace air; that alone does not mean something is wrong. A faint dusty smell can occur at first startup, but it should fade quickly. Persistent burning odors, smoke, loud banging, or repeated shutdowns need attention. Turn the system off if you notice these problems and arrange service; for smoke or fire, leave and call 911. If you smell gas, leave immediately without operating switches or phones indoors, then call your gas utility’s emergency line or 911 from outside. If a carbon monoxide alarm sounds, leave immediately and call 911.
Complete Fall Safety Checks and Know When to Call
Test smoke and carbon monoxide alarms according to their instructions, and check their replacement dates. From a safe ground-level location, look for leaves or other obstructions around accessible outdoor combustion vent openings. Do not disconnect vent pipes, open combustion compartments, or attempt burner adjustments. Schedule professional maintenance if it is due, especially before relying on the heat daily. A technician can check safety controls, electrical components, and heating performance, with combustion checks where applicable. Call if the system will not start after basic thermostat and filter checks, heats unevenly, or repeatedly cycles off.
