Switching From AC to Heat the Right Way in Edison, 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 weather in Edison can mean cooling one afternoon and heating the next morning. Before switching modes, a few simple checks can help you catch airflow problems, confirm safe operation, and avoid an uncomfortable surprise when colder weather settles in.
Start With the Thermostat, Not a Big Temperature Jump
Choose a mild day for your first heating test so you have time to address a problem before you need steady heat. If the AC is running, turn the thermostat to Off and let the equipment stop before selecting Heat. Follow your thermostat or equipment manual for any required delay, and avoid repeatedly toggling between modes. Set the temperature a few degrees above the room temperature and set the fan to Auto for a typical forced-air system. Raising the setting dramatically will not make the home warm faster and may trigger auxiliary heat on some heat pumps. Review schedules and replace thermostat batteries if your model uses them.
Check Filters, Vents, and Outdoor Equipment
For a forced-air system, turn the equipment off before checking the air filter. Replace a dirty disposable filter with the correct size and a filtration rating approved for your equipment; follow the manufacturer's directions for washable filters. Keep supply registers and return grilles clear of rugs, furniture, and curtains. If you have baseboard or radiator heat, keep furnishings away from heating surfaces and follow the equipment's clearance guidance. Outside, remove loose leaves around equipment without opening panels or reaching inside. A heat pump's outdoor unit runs during heating, so do not cover it. Check accessible exterior combustion intake and exhaust openings for obvious blockages, but leave disassembly and difficult access to a professional.
Run a Short Test and Know the Warning Signs
Let the heat run while you are home and check that the indoor temperature begins moving toward the setting. Heat-pump air may feel less hot than furnace air, so judge performance by room temperature rather than touch alone. A faint dusty odor can occur at first startup, but it should fade quickly. Stop the system and call for service if a burning smell persists, the unit repeatedly starts and stops, or you hear unusual banging or grinding. If you smell gas or suspect a gas leak, leave immediately without operating switches or phones inside, then contact the gas utility's emergency line or 911 from outside. If a carbon monoxide alarm sounds, evacuate and call 911.
Arrange Maintenance Before Heating Becomes Essential
Test smoke and carbon monoxide alarms using their test buttons, and follow their instructions for battery changes, placement, and replacement dates. Alarms do not replace professional equipment inspections. Schedule heating maintenance if it is due, especially if last season brought uneven temperatures, ignition trouble, or unexplained shutdowns. A technician can check electrical components, controls, and airflow; fuel-burning equipment also needs attention to combustion safety and venting. Do not adjust gas valves, bypass safety switches, or repeatedly reset a system that shuts down.
