Switching From AC to Heat in North Arlington, 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.
A cool fall evening in North Arlington is a good reminder to check your heating system before you depend on it every day. A few simple steps can help you switch from cooling to heating safely and catch problems before colder weather arrives.
Start With the Filter and Airflow
Before your first heating test, turn the system off at the thermostat and check the air filter if your equipment uses one. Replace a dirty disposable filter with the size and type recommended for your system; follow the manufacturer’s directions for washable filters. Do not run the equipment without its filter. Walk through the house and make sure supply registers and return grilles are not blocked by rugs, furniture, or curtains. If you have radiators or baseboard heat, keep furnishings and other belongings clear according to the equipment’s clearance requirements. Avoid opening equipment panels or touching wiring, burners, or refrigerant lines.
Change Thermostat Modes and Run a Short Test
Choose a mild day when you can stay home and observe the system. If the AC is running, switch the thermostat to Off and let it finish shutting down before selecting Heat. Follow any waiting period listed in your thermostat or equipment manual, and avoid repeatedly toggling between modes. Set the heating temperature a few degrees above the room temperature. For most forced-air systems, use Fan Auto so the blower follows the heating cycle. Allow for normal startup delays rather than raising the setting repeatedly. Check that the house begins warming and the system eventually satisfies the thermostat. Heat pump air may feel less hot than furnace air while still heating effectively.
Know Which Startup Signs Need Attention
A faint dusty smell can occur briefly when heat first runs after months of disuse, but it should fade quickly. If it persists, shut the system off and arrange an inspection. Smoke, a strong burning odor, or an electrical smell is not something to ignore; stop using the equipment and seek professional help. For visible fire or significant smoke, leave and call 911. If you smell gas or suspect a gas leak, leave immediately without operating switches or using a phone inside, then call your gas utility’s emergency line or 911 from outside. A carbon monoxide alarm also means everyone should leave immediately and call 911. Do not reenter until responders say it is safe.
Prepare for Regular Heating and Call When Needed
Test smoke and carbon monoxide alarms using their test buttons and follow the manufacturer’s replacement schedule. From a safe ground-level position, look for leaves or debris blocking accessible outdoor heating vents; do not dismantle venting or climb to inspect it. If you have a heat pump, keep its outdoor unit unobstructed and uncovered because it operates during heating season. Schedule professional maintenance if it is due, especially for fuel-burning equipment. Call for service if the system will not start, repeatedly stops and restarts, makes unusual noises, or fails to warm the home.
