Switching From AC to Heat This Fall in Montclair, NJ
Switch from AC to heat safely this fall with simple thermostat, filter, and vent checks, plus warning signs that tell you when to call an HVAC professional.
Fall in Montclair, NJ, is a good time to make sure your heating system is ready before you need it every day. A few simple checks can help you switch from cooling to heating safely and spot problems before colder weather arrives.
Start With the Thermostat and a Short Test
Choose a day when you can stay home during the first heating test. If the AC is running, switch the thermostat to Off and let the system stop before selecting Heat; follow any waiting period specified in your equipment manual. Set the temperature a few degrees above the current room temperature and leave the fan on Auto. Raising the setting much higher will not heat the house faster. Allow for normal startup delays rather than repeatedly switching modes. Check that the system starts and begins warming the home. If it does not, confirm the thermostat settings and batteries, if applicable, before calling for service.
Check the Filter and Keep Air Paths Clear
For a furnace or ducted heat pump, inspect the air filter before your test. Turn the system off at the thermostat before removing it, and replace a dirty disposable filter with the size and type recommended for your equipment. Match the airflow arrow to the direction marked on the housing or shown in the manual. Do not run the system without its filter or assume a more restrictive filter is better. Keep supply registers and return grilles free of furniture, rugs, and curtains. If you have radiators or baseboard heat, keep their heat-emitting surfaces unobstructed instead. Leave equipment panels, wiring, and internal cleaning to a professional.
Know What Changes With Your Heating System
Not every home switches seasons the same way. A heat pump uses its outdoor unit for heating as well as cooling, so do not cover it or shut off its power for winter. Keep leaves and loose debris away without opening the cabinet or reaching inside. Heat pump air may feel less hot than furnace air while still warming the house normally. If you use a boiler, confirm that the thermostat is set for heat and watch for visible leaks around accessible piping. Do not adjust boiler pressure, bleed radiators, or operate unfamiliar valves unless your system instructions clearly explain a safe homeowner procedure. Ask a technician if you are unsure.
Recognize Warning Signs and Safety Emergencies
A brief dusty odor can occur when heat first runs after months of disuse, but it should fade promptly. Persistent burning smells, smoke, grinding noises, repeated shutdowns, or failure to warm the home need professional attention. Stop using equipment that appears unsafe. If you smell gas, leave immediately without operating switches, thermostats, or phones indoors; call your gas utility or 911 from outside. If a carbon monoxide alarm sounds, get everyone outside and call 911. Do not reenter until responders say it is safe. Test smoke and carbon monoxide alarms according to their instructions, and replace expired devices. Never bypass a safety control or repeatedly reset a tripping breaker.
Plan Fall Service Before Daily Heating Begins
A successful test is helpful, but it does not replace maintenance. A qualified technician can check the components appropriate to your system, including electrical connections, airflow, operating controls, and, for fuel-burning equipment, combustion and venting. Schedule an inspection if maintenance is overdue, your system struggled last winter, or your test reveals uneven heating or unusual cycling. Note any thermostat messages, sounds, or rooms that stay cold so you can describe the problem clearly.
