EXCLUSIVE: “Do as I Say, Not as I Chill” — NYC Mayor Mamdani’s 78-Degree AC Plea Backfires as City Hall Plunges to a Bone-Chilling 54 Degrees During 100°F Heat Wave

New York, NY – July 4, 2026

While New Yorkers were sweating through the city’s first 100-degree day in more than a decade, sweating in their apartments with thermostats cranked to the “recommended” 78°F or higher, one place stayed ice-cold and luxurious: the very building where Mayor Zohran Mamdani works.

In a stunning act of apparent “rules for thee but not for me,” temperatures inside historic City Hall and surrounding municipal offices dropped as low as 54 degrees — sweater-and-hot-chocolate weather — even as the mayor publicly begged residents to turn their air conditioners way up to prevent power grid collapse.

New York Post reporters, armed with infrared thermometers, fanned out across City Hall and accessible municipal buildings Thursday during the blistering heat wave. Out of 20 spots tested, 15 were significantly below the 78-degree target Mamdani himself had just promoted. Some rooms felt like walk-in freezers.

At noon — two hours before Central Park officially hit 100°F for the first time in years — areas near the mayor’s second-floor office, the grand Rotunda, the Governors’ Room, and the City Council chambers all hovered around a comfortable 77°F. The mayor’s press office sat exactly at 78°F.

But then the cold snap hit.

By mid-afternoon, the Rotunda had plummeted to 64°F. The Governor’s Room (where staff were frantically setting up for Mamdani’s Fourth of July address) dropped to 74°F. Outside the mayor’s own office: 74°F. And in the press radio room — a spot reporters have long complained feels like an Arctic outpost — the air blasting from the AC unit registered a jaw-dropping 54°F.

Even the souvenir-packed CityStore inside the Manhattan Municipal Building was a frosty 64°F, perfect for tourists buying “I  NY” merch while shivering.

Meanwhile, the people actually protecting the buildings weren’t so lucky. Security officers and police standing in hallways and lobbies of the Dinkins Building endured 80–89°F heat with no fans provided. Elevators felt like saunas at 89°F. The Mayor’s Office of Climate and Environmental Justice — ironically empty at the time — was a toasty 81°F.

The hypocrisy exploded online almost instantly.

Republican City Council Minority Leader David Carr (R-Staten Island) fired back: “Maybe the mayor shouldn’t tell New Yorkers to sacrifice their comfort if he isn’t willing to do the same.”

Barstool Sports founder Dave Portnoy and countless others roasted the democratic socialist mayor with memes about “the warmth of collectivism.”

Mamdani had taken to X (formerly Twitter) the day before, urging: “Our City is doing its part too: maintaining the 78 degrees rule in our buildings…”

Yet when Post reporters showed up, City Hall was running colder than a meat locker.

After the newspaper’s findings, the mayor’s office suddenly scrambled. Spokesman Jeremy Edwards confirmed late Thursday that “City Hall’s temps were also set to the recommended levels” after The Post “turned up the heat.”

Edwards also noted that Mamdani personally set Gracie Mansion (the mayor’s residence) to exactly 78°F the previous afternoon.

For context, this isn’t entirely new advice. Former Mayors Eric Adams and Bill de Blasio gave the same 78-degree recommendation during past heat waves. Even Republican icon Rudy Giuliani reportedly did the same years earlier. The U.S. Department of Energy has long suggested 75–78°F as an energy-saving sweet spot in summer.

But the optics this time were brutal — especially as roughly 5,000 Con Edison customers in the Bronx’s Riverdale neighborhood lost power Thursday. The utility had to cut electricity temporarily “to prevent more extended outages.”

Mamdani’s top spokesperson Joe Calvello spent the day aggressively defending the mayor on X, reminding critics that the 78-degree plea is standard practice.

Still, the contrast is impossible to ignore: while ordinary New Yorkers were told to sweat it out in 100-degree apartments to “save the grid,” the mayor’s workplace had apparently cranked the AC so aggressively that staff could see their breath in some rooms.

The Post’s exclusive investigation shines a harsh light on a classic political trap: preaching sacrifice while enjoying comfort behind closed (and very well-air-conditioned) doors.

As one sarcastic social media comment put it: “Climate justice for thee… but central air for me.”

With another scorching weekend forecast, New Yorkers are left wondering: Will City Hall finally practice what it preaches — or will the freezers stay on full blast while the rest of the city melts?

We’ll keep the thermometer ready.

What do you think? Should elected officials be forced to live under the exact same rules they push on citizens? Or is this just another day in New York politics?
