Your Heat Is Out. Here's What to Do Right Now.

Putnam County is the coldest county we cover. January lows average 17 degrees in the inland areas. During polar vortex events, it goes below zero. The county is also the most rural, which means fewer HVAC contractors and potentially longer response times for emergency calls.

About 61% of Putnam homes run on natural gas (NYSEG service territory). Another 14% use heating oil, with propane filling in where gas lines don't reach. The eastern and northern parts of the county, particularly Kent, Patterson, and parts of Putnam Valley, have more homes on oil and propane because the gas infrastructure doesn't extend that far.

We list 20 HVAC contractors in Putnam County. That's the smallest pool in our coverage area. Here's how to handle a furnace emergency when help might be a few hours away.

5 Things to Check Before You Call Anyone

With only 20 HVAC companies serving the county and potentially long wait times, it's even more important to rule out simple problems first.

1. Check the thermostat. Set to HEAT. Set above current room temp. Replace batteries if digital. This solves the problem a surprising percentage of the time.

2. Check the circuit breaker. Gas, oil, and propane furnaces all need electricity. Find the furnace breaker. Off. Wait 30 seconds. On. If it trips again immediately, that's an electrical issue.

3. Check the filter. A clogged filter triggers a safety shutdown. Pull it out and look. If it's thick with dust, replace it. Hardware stores in Carmel, Brewster, and Mahopac carry standard filter sizes.

4. For gas furnaces: check the pilot light or igniter. Older units have a standing pilot visible through a window at the base. If it's out, follow the relighting instructions on the sticker inside the panel.

5. For oil or propane systems: check fuel levels. Oil tank gauge should be above 1/4 tank. If you're on propane, check the tank gauge outside (flashlight helps). Running out of fuel in Putnam County in January is a serious situation because emergency delivery may take hours.

For oil burners: there's a red reset button on the unit. Press it once. If the burner fires and dies, press once more. Two tries max. After that, you need a technician.

If You Smell Gas, Stop Reading and Do This

Note

Putnam County has two gas/electric utilities. Know which one serves your area.

1. Do NOT flip switches or use your phone inside the house. 2. Get everyone outside immediately. 3. Call 911 from outside. 4. Call your utility's gas emergency line: - NYSEG: 1-800-572-1121 — Serves most of Putnam County - Central Hudson: 1-800-942-8274 — Serves parts of Putnam Valley and Philipstown 5. Do not go back inside until cleared by the fire department or utility.

If you're on propane (common in Kent, Patterson, and rural Putnam), the gas smell will have a stronger "rotten egg" odor. Turn off the propane tank valve outside (clockwise to close), evacuate, and call 911. Then call your propane supplier's emergency line.

What Emergency HVAC Costs in Putnam County

Keeping Your House Safe While You Wait

Putnam County wait times for emergency HVAC can be 2 to 4 hours or longer, especially on the coldest nights when every HVAC company is slammed. You need a plan for those hours.

Protect pipes immediately. Open cabinet doors under sinks. Let faucets drip. Pipes in crawl spaces, garages, and exterior walls are the most vulnerable. Many Putnam County homes have well water. If your well pump is in an unheated pump house or crawl space, wrap those pipes with towels or blankets.

Close off the house. Pick the room with the most south-facing windows (for morning sun) or the smallest room. Close everything else. Towels under doors.

Space heaters. 3-foot clearance from anything flammable. Plug into wall outlet. One per circuit. Never leave unattended. Don't run while sleeping.

Wood stove or fireplace. Common in Putnam County homes. Open the damper before lighting. Use seasoned hardwood. Keep a fire extinguisher nearby. If you haven't had the chimney cleaned this year, use the fireplace sparingly. Creosote buildup causes chimney fires.

Propane space heater (indoor-rated only). Some Putnam homeowners have these as backup. They produce CO. Crack a window for ventilation. Run a CO detector in the same room. Never use an outdoor-rated propane heater indoors.

Check CO detectors. Amanda's Law requires them in every New York home with fuel-burning appliances. When you're running backup heat sources, CO risk goes up. Press the test button on every detector in the house.

When to leave: If indoor temp drops below 45 degrees and you can't hold it, go to a friend's home, family member's house, or call 211 for local warming center locations. Pipes can be drained to prevent freezing. Your family's safety comes first.

Putnam County-Specific Challenges

Putnam has heating challenges the other counties in our coverage area don't.

Fewer HVAC contractors. We list 20 in the county compared to 141 in Westchester. Some Westchester-based companies also serve southern Putnam (Mahopac, Carmel), but during a cold snap, everyone is booked.

More homes on oil and propane. The gas infrastructure doesn't extend to Kent, Patterson, or the eastern parts of the county. These systems require different maintenance (annual oil burner cleaning, propane tank inspections) and different emergency protocols.

Well water. Most Putnam homes are on private wells, not municipal water. If your furnace is out and the house freezes, the well pump and the pressure tank in your basement are at risk. The well supply line, which runs underground, is usually safe below the frost line. But the above-ground plumbing in the basement can freeze if the house drops below 40 degrees.

Power outages. Putnam County loses power during ice storms and heavy snow more than the more urban counties. If the power goes out AND the furnace goes down, you've lost both heat and the ability to run space heaters. A portable generator ($500 to $2,000) can run the furnace blower and a few essentials. Use it OUTSIDE or in a well-ventilated detached garage. Never run a generator inside or in an attached garage.

Longer driveways. HVAC techs serving rural Putnam sometimes ask for detailed directions or need to be told about long or unpaved driveways. Have your address and any access notes ready when you call.

Finding Emergency HVAC in Putnam County

We list 20 HVAC contractors in Putnam County. When a polar vortex hits, they're all busy.

Strategy: Call 3 companies. Include at least one Westchester-based company that services southern Putnam. First to confirm a time gets the job.

Mahopac and Carmel are close enough to Westchester that companies from Yorktown Heights, Cortlandt, and Mount Kisco regularly service the area. You have more options than the 20 Putnam-only companies suggest.

Brewster and Southeast are near the Fairfield County, CT border. Some Connecticut HVAC companies will cross the state line, though they'd need to be licensed in New York to do work here.

Kent and Patterson are the most remote. Plan ahead by establishing a relationship with a local HVAC company before you need emergency service. A maintenance contract ($150 to $300/year) guarantees priority scheduling when you call at 2AM.

Before the tech arrives: Have your furnace or boiler model number (sticker inside access panel), fuel type (gas, oil, propane), and description of what happened. If you're in a hard-to-find location, text the tech your address pin from Google Maps.

Preventing the Next Emergency

Fall tune-up in October. $80 to $200. Non-negotiable on a system older than 10 years. The tech inspects the heat exchanger, cleans burners, and tests safety controls. This is where cracked heat exchangers and failing igniters get caught.

Oil systems need annual cleaning. Putnam has a lot of oil heat. Soot accumulation, clogged nozzles, and dirty filters cause most oil burner emergencies. Annual service costs $150 to $250 and should happen before heating season.

Keep fuel topped off. If you're on oil or propane, don't let the tank drop below 1/4. Automatic delivery service from your fuel company prevents the "ran out at 2AM" situation.

Replace the filter every 1 to 3 months. Cheapest insurance against a shutdown.

CO detectors. Test monthly. Replace batteries annually. Amanda's Law requires them in every room within 15 feet of a sleeping area.

Save these numbers in your phone now: - NYSEG gas emergency: 1-800-572-1121 - Central Hudson gas emergency: 1-800-942-8274 - 211 (for warming centers and emergency assistance)

If your system is over 15 years old, plan the replacement. Don't wait for the emergency. NYSERDA offers $1,000 to $2,000+ in rebates on heat pumps, and the federal tax credit covers 30% of heat pump costs up to $2,000. A planned replacement in September gives you choices. An emergency replacement in January gives you whatever the tech has available.

Consider a generator. For $500 to $2,000, a portable generator can keep your furnace blower and a few lights running during a power outage. In Putnam County, where power outages happen several times per winter, this is a practical investment.
