Switching From AC to Heat in Hillsborough, NJ
Switch from AC to heat safely this fall with thermostat tips, filter checks, warning signs, and advice on when to call an HVAC professional in Hillsborough, NJ.
Fall weather in Hillsborough, NJ, can mean cooling one afternoon and heating the next morning. A few simple checks before changing modes can help you catch problems early and get your home ready for colder nights.
Check the Filter, Vents, and Equipment Area
Before your first heating test, turn the system off at the thermostat and inspect the air filter if your system uses one. Replace a dirty disposable filter with the size and type recommended for your equipment; clean reusable filters only as directed by the manufacturer. Keep supply registers and return grilles open and clear of furniture, rugs, and curtains. If you have radiators or baseboards, keep their heat outlets unobstructed instead. Move stored items away from the furnace or boiler, especially paper, paint, and cleaning products. From ground level, look for leaves or other debris around accessible outdoor intake and exhaust openings. Leave equipment panels and vent piping alone.
Change Thermostat Modes and Run a Short Test
Choose a mild day when you can stay home for a heating test. Let an active cooling cycle finish, switch the thermostat to Off, and follow any waiting period specified in your equipment manual before selecting Heat. Avoid repeatedly flipping between modes. Set the temperature a few degrees above the current room temperature and, for forced-air systems, set the fan to Auto. Allow for normal startup delays rather than immediately raising the setting again. Check that the home begins warming and that airflow feels normal. Heat pumps often deliver air that feels less hot than furnace air. Review schedules and replace thermostat batteries if needed.
Know Which Startup Signs Need Attention
A faint dusty smell can occur when heating equipment first runs after sitting unused, but it should fade rather than intensify. Persistent burning odors, smoke, electrical smells, loud banging, or repeated shutdowns are not normal. Stop using the system and arrange professional service; if there is smoke or fire, leave and call 911. If you smell gas, leave immediately without operating switches, thermostats, or phones indoors, 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.
Prepare for Cool Nights and Schedule Service When Needed
Once the test is complete, choose a comfortable heating setting and update your thermostat schedule. With a heat pump, large temperature increases can trigger auxiliary heat on some systems, so follow the manufacturer’s scheduling guidance. Do not shut off power to or cover an outdoor heat pump: it needs to operate during heating season. If the system blows cool air continuously, cannot reach the setting, or cycles on and off frequently, check the thermostat and filter before calling a professional. Avoid opening electrical compartments or attempting burner repairs. For seasonal maintenance or help with the transition, contact General Air Pro Heating & Cooling at (609) 248-6446.
