A free seasonal checklist for homeowners in Binghamton and the rest of Broome County, from Get HVAC Pros.

What NOAA lists for Binghamton/Broome County

NOAA's engineering weather data lists a station named Binghamton/Broome County, about 8 miles north of the city. For that station NOAA gives a 50-year basic wind speed of 90 mph (3-second gust at 33 feet), a 100-year rainfall rate of 2.3 inches per hour and about 55 freeze-thaw cycles in an average year.

Households in Census QuickFacts

U.S. Census Bureau QuickFacts counts 21,393 households in Binghamton for 2020-2024, with 2.13 persons per household. For the same 2020-2024 period it gives an owner-occupied housing unit rate of 44.0%, a median value of owner-occupied housing units of $124,800 and a median gross rent of $870.

How to use this list

Rather than a month-by-month list, this one walks you around the house, stopping at each place where the heating and cooling system can be seen or touched, and notes what to do there as the seasons change. Carry it on the first cool morning and again on the first hot afternoon. Tasks marked Tech call for a technician with instruments. Before you open any cover or touch the outdoor unit, set the thermostat to off and switch off power at the furnace switch or the outdoor disconnect.

Stop one: the outdoor unit

Spring

  • Clear away winter debris and move bikes, bins or firewood stacked against the cabinet.
  • Power off, then let a garden hose on a soft spray wash the coil, working downward. A pressure washer can flatten the fins, so leave it in the garage.
  • Set a level on the pad, and look for torn or missing foam on the fatter of the two copper lines.

Summer

  • Keep shrubs trimmed to the clearance in the installation manual.
  • Aim the mower so clippings blow away from the coil.
  • If frost forms on the copper lines, switch the system to fan only and call.

Fall and winter

  • For a heat pump, keep roof drips and drifted snow off the top and sides, and let defrost cycles finish on their own. A cloud of steam during defrost can be part of that cycle.
  • For an air conditioner that sits idle, ask your technician whether a cover suits that model, and if so which kind.

Tech: refrigerant pressures written on the ticket, capacitor and contactor, and tightness of electrical connections.

Stop two: the furnace or air handler

Every running month

  • Pull the filter, hold it to a light, and swap it once light barely passes through. Mark the date on the frame.
  • Glance at the floor and drain pan for water or rust stains.
  • Clear the space around gas equipment of anything that burns easily: paint thinner, cleaning rags, cardboard boxes.

Before heating season

  • Run the heat on a cool day before you rely on it. A brief dusty smell at first can be normal; a smell of hot plastic or wiring means shut it off and call.
  • If there is a humidifier, replace its pad and open the water valve.

Before cooling season

  • Find where the condensate line ends and clear anything blocking it. If there is a condensate pump, pour in a cup of water and watch it run.
  • Close the humidifier valve.

Tech: for a gas furnace, burners, flame sensor, ignitor, heat exchanger inspection, gas pressure and a combustion reading; for a heat pump's indoor side, the blower, coil and backup heat.

Stop three: the thermostat

  • Replace batteries if it uses them, at the same time each year.
  • Review the schedule when the household routine changes.
  • With a heat pump, ask your installer how deep a nighttime setback can go before backup heat comes on.
  • Watch whether auxiliary or emergency heat appears often, and note the dates.

Stop four: registers, returns and ducts

  • Walk each room and make sure no sofa, bed skirt or drape is sitting over a register or a return grille.
  • In the basement or attic, look along reachable duct runs for joints that have separated or tape that has peeled.
  • Note any room that lags in summer afternoons or winter mornings, and add it to the next service ticket.

Stop five: vents and pipes on the outside wall

  • After each snowfall, brush clear the plastic intake and exhaust pipes of a high-efficiency furnace by hand.
  • In fall, check those pipes and any dryer vent nearby for leaves, nests or debris.
  • Keep snow piles from the driveway away from the vent wall.

Stop six: alarms

  • Press the test button on each smoke and carbon monoxide alarm the week the heat comes on, and put in fresh batteries for any that take them.
  • Should a carbon monoxide alarm go off, leave the house with everyone in it, and phone for help once you are outdoors.

After a storm or a power outage

  • Give the power a little time to settle before turning the system back on, then confirm the thermostat kept its schedule.
  • Circle the outdoor unit looking for limbs, crushed fins or a pad knocked off level.
  • If water reached the furnace, air handler or outdoor unit's base, leave the system off and ask a technician to inspect it first.
  • Photograph any damage before cleanup, and call your insurer to ask what they need.

Signs it is time for a technician

  • The system's breaker flips off a second time after you reset it.
  • Short cycling: the burner or compressor shuts down soon after starting, again and again.
  • A puddle forming beside the furnace or air handler.
  • Soot near the burner, or a flame that turns yellow, lifts or flickers.
  • Frost building on copper lines or the indoor coil.

If replacement comes up

When a repair estimate grows large, ask the same company to price a replacement too, and put these questions to anyone quoting:

  • How did you arrive at the capacity you are proposing, and can I see the calculation behind it?
  • Which matched indoor and outdoor pair are you quoting, and under what AHRI reference?
  • Is fixing leaky ductwork part of this price or a separate line?
  • What state license or registration, if any, covers this work, and what is the number?
  • Does the swap call for a city permit and an inspection, and who arranges them?
  • May I see a certificate showing liability coverage and workers' compensation?

Keep a service log

Clip a sheet to the side of the furnace or keep a note on your phone. List the filter size and each change date, every visit with what the technician measured and replaced, any refrigerant added, and the model and serial numbers of each piece of equipment. A log like that gives the next technician a head start and supports a warranty claim with dates.
