679. Mastering Winter Heating Efficiency and Rising Energy Costs | Deep Dive Episode 679

There is this very specific, very universal kind of dread. You know the feeling I'm talking about?

Oh, yeah.

It's late January, maybe mid February. The holidays are over, decorations are down, and you walk out to the mailbox.

You're not prepared for what's coming.

Not at all. You're shivering a little bit. The wind is cutting right through your bathrobe. And you pull out that one envelope. The utility bill.

The post holiday reality check.

Exactly. And you stand there in the driveway and you open it up, you know, bracing yourself.

You're thinking, okay, it'll be a little higher, right?

We ran the heat a bit more. The kids were home. But then, boom, you see the number, and it's not just up a little. It is a shock to the system. It's a number that makes you physically stop.

That's the moment where you start questioning everything. You're just standing there thinking, did I leave a window open for three weeks? Is there a hole in my wall I don't know about?

Yes. You look for a conspiracy because the MA just doesn't seem to make sense. And look, the first thing we want to tell you today, based on the research in front of us, is you are not imagining it.

You aren't crazy.

Not at all. That number really is jumping. And that sinking feeling is happening to homeowners all across the country.

It is the universal feeling of winter 2026.

But here's the thing. Just knowing it's happening doesn't help your bank account. Commiserating doesn't pay the bill. So the mission of this deep dive is a little different. We aren't just here to complain that stuff costs more. We know that. We are here to unpack the specific mechanism behind that high bill. We want to understand the why and, you know, more importantly, the how to stop it.

We need to move from shock to strategy.

To do that, we are doing a deep dive today into a really timely, really insightful piece of writing. It's a blog post titled Winter Heating Bills Are Rising. Here's what that really means for homeowners. It was written by a guy named Derek Cole.

And this is a great source for us because Derek Cole isn't just some guy ranting on a forum about gas prices. He is. I mean, he's deeply embedded in this world. He's the general manager of Simmons One Hour Heating and Air.

So he's in the trenches.

Absolutely. He has over two decades of experience in the H vac industry. He's been recognized as a top 40 under 40 by news magazine. You've probably seen him on CBS, Fox, NBC, you know, giving home comfort tips.

So when he says something is happening, he isn't guessing.

No, he's got the field data and 20 years of seeing what breaks and what works to back it all up.

And the context here, this is crucial for you listening. This source material is from late December.

2025, right at the tail end of last year.

So he's looking ahead to the winter we are currently living through here in early 2026. It was essentially a warning flare he sent up right before the worst of.

The cold hit, which makes it incredibly relevant right now because you're probably living through the exact scenario he predicted.

Okay, so let's get into the meat of it. Cole lays out what I'm calling the unholy trinity of high bills. He says, and I'm quoting here, cold weather, higher energy prices, and older heating systems don't mix.

It's the perfect storm. And what's fascinating is that these three things, they don't just add up. They compound. They multiply each other.

Let's break them down one by one so we can really get the physics of what's happening to our wallets. First, factor one, energy costs.

This is the baseline, and unfortunately, it's the one we have the least control over. Cole points out that national reporting, you know, places like the New York Times, they've been tracking this. It's just a macroeconomic reality. The unit price of energy, whether it's gas or oil or electricity, it's gone up.

So even if you use the exact same amount of heat as three years ago, the bill is higher just because the REIT is higher.

Exactly. That's the starting line. The entry fee for the race has just gone up.

Which brings us to factor two, the weather. Now, we all knew this winter was predicted to be cold. But cold gets into the relationship between the outdoor temperature and your system in a way I don't think most people consider right.

It's not just. It's cold, so the heater runs. We should talk about something called Delta.

T. Delta T. Okay, let's unpack that.

In engineering, Delta T is the temperature differential. It's the gap between the temperature outside and the temperature you want inside. So if it's 40 degrees outside and you want it 70 inside, your system has to bridge a 30 degree gap. That's manageable, following you. But if a cold front comes through and it drops to 10 degrees outside and you still want 70 inside, now that gap is 60 degree. The gap is doubled.

So the system Works twice as hard, at least.

It's actually worse than that, because as that gap gets wider, the rate at which your home loses heat accelerates. Heat always moves to cold.

Oh, okay.

So when it's 10 degrees outside, the heat is just flying out of your house much faster than when it's 40. Your system is fighting a war on two fronts. A bigger gap to bridge and replacing heat that's escaping faster.

That makes so much sense. And it leads us to factor three. And this is where it gets really interesting, because this is the one we can actually do something about the equipment.

This is the variable that changes the whole equation. Cole points out that a huge number of homes are running on, well, essentially borrowed time. They're using old, inefficient equipment to fight these higher prices. And this huge Delta T. He uses this great visualization.

In the text, he talks about the utility meter. You know, we all know what it looks like, that old spinning disc or the flashing numbers. But he says when a heater has to struggle to keep up, that meter isn't just spinning, it spins faster.

It's such a kinetic image, isn't it?

It is.

It really helps you visualize where the money is going. It's not just that the machine is on. It's the intensity. If your machine is struggling, it is literally devouring more energy, more amps, more gas, just to produce the same amount of heat. You're paying a premium for the struggle.

Which brings us to one of my favorite lines in the whole piece. It's witty, but it's also just a harsh truth. He says heating systems don't age like fine wine.

I love that line. It cuts right through the denial. You know, a wine gets complex. A mechanical system just gets friction.

Right. I mean, think about what's happening inside that box.

Exactly. Bearings are drying out. Belts are stretching. Heat exchangers are expanding and contracting. Thousands of times entropy is coming for that machine. It degrades. And as it degrades, efficiency just plummets.

He gets really specific about the time frame, too. He calls it the danger zone. What ages are we talking about?

He flags systems that are 10 to 12 years old or more. So if your system is in that, you know, teenager phase, you are in the danger zone.

That feels terrifyingly young. I think most people buy a house, the inspector says, furnace turns on, and they just assume they're good for 20 years.

That's the magical thinking of homeownership. We think if we don't look at it, it's fine. But Cole calls that a roll. Of the dice.

Waiting until it quits isn't a plan. It's a roll of the dice. That line hit me hard.

And then he adds the kicker. Winter is the worst time to find out you lost. Yeah, I mean, think about that moment. If your heat goes out in July, it's annoying. If it goes out in January during a freeze, that is an immediate crisis.

You'Re in a panic.

You are. You're paying emergency rates. Parts might be backordered because everyone else's system is failing. Pipes could freeze. You have zero leverage. You just have to pay whatever it costs.

So besides just age, what are the red flags he tells us to look for? How do we know if we're rolling the dice right now?

He list a few specific sins. Skipping yearly maintenance is the big one. If no one's looked inside that unit in two years, you were gambling, full stop. Okay, running with dirty filters is another huge one. And poor airflow if you have rooms that are always cold spots.

And the scary part is the compound effect we talked about.

Right? It goes back to that unholy trinity. If you have an old system, that's factor three, and it's poorly maintained, and you add in high energy prices, Factor one, that lack of maintenance costs you exponentially more than it did five years ago.

So that 10% of wasted energy from five years ago was maybe annoying, but now that same 10% waste is costing you a fortune.

Precisely. The penalty for inefficiency, the stupidity tax for not maintaining your system is just much, much higher today.

Okay, so that's the doom and gloom. Let's pivot to solutions. What does Cole say we should do?

I like that he explicitly says no gimmicks.

He does? Yes. You don't need gimmicks or trendy upgrades. I think that's so refreshing. So often people try to sell you some magical gadget. Cole says no. Pivot to the basics. Do the basics. Right. So step one, the professional tune up. Now, be honest. Is this just a way for companies to make money, or does it actually matter?

It's a cynical question. But a fair one. According to Cole, it matters immensely. Yeah, but you have to change how you look at it. He frames it as a diagnostic intervention.

Diagnostic intervention? That sounds a lot more serious than checking the heater.

It is. It's not just dusting it off. It's about catching small problems before they become catastrophic breakdowns. For example, a technician might find a loose wire. Tightening it takes 10 seconds. Okay, but if you skip that tune up, that loose wire creates resistance Resistance creates heat, and eventually it arcs and burns out your main control board. Now, Instead of a 10 second fix, you have a $600 repair on the coldest night of the year.

Plus the emergency fee.

Exactly. It's preventative medicine. It's about getting the machine as close to factory specs as possible so it doesn't have to struggle. Remember, struggle equals money.

Step two. This is the one everyone knows they should do. But I bet half our listeners are guilty of forgetting the air filter.

The humble air filter. Cole is very emphatic about this. This is the single highest ROI return on investment action you can take as a homeowner.

He uses a really visceral word. He says a D filter chokes the airflow.

That's the key mechanic to understand your heating system. It breathes in a loop. It pulls air from your house, heats it, and pushes it back out.

Right.

If that filter's clogged with dust and dog hair, you're increasing what engineers call static pressure. It's like trying to run a marathon while breathing through a coffee stirrer.

That sounds awful.

It is. Your lungs would work 10 times harder. That's exactly what your blower motor is doing. It has to ramp up, use way more electricity, and strain itself just to move air through that wall of dirt.

So you're forcing the system to work.

Harder than necessary, which spins the meter faster and it causes the system to overheat because the air isn't moving fast enough. It's a cascade of failure, all from a $15 piece of fiberglass.

And his verdict?

Simple, cheap, and it makes a real difference.

I noticed a little side note in the source, too. He mentions his company offers home delivery.

For filters now, which just highlights that there's really no excuse anymore. You don't even have to go to the hardware store. They're trying to remove every obstacle so you actually do the maintenance.

Okay, step three. We're moving away from the machine itself and looking at the house, tightening the envelope.

This is so crucial. You can have the most efficient furnace in the world, a 98% efficient marvel of engineering. But if you're trying to heat a tent, you're going to be broke.

Heating a tent. That's a vivid image. What culprits does he point out?

Drafty doors, attic leaks, and one that's often invisible. Unsealed ductwork.

Unsealed ductwork is one I feel like people just totally miss. Why is that one so bad?

Well, think about where your ducts usually are in the attic. A crawl space. Those are unconditioned spaces. It's freezing in there, right? So if those metal tubes have holes or the joints are pulled apart, you are pumping that expensive hot air directly into your attic. You're just heating the squirrels. Cole puts it perfectly. That's money going right out the door.

So seal it up. Weather strip the doors. Keep the heat where it belongs.

Keep the heat inside the thermal envelope. Exactly.

Step four, thermostat discipline. Does this mean we have to freeze? Do I have to wear a parka to dinner?

No. And Cole is careful to say without sacrificing comfort. He's not saying set it to 55 degrees and suffer. He suggests a strategy called setback.

Sit back.

Just dropping the temperature a couple of degrees at night or when you're away at work. The energy savings from a setback of even 2 or 3 degrees over an 8 hour period are significant. It reduces the load on the system, gives the machine a break.

So tune up. Filter envelope, thermostat. The basics. But Cole pivots again near the end. He raises the stakes. We've been talking about money, but he says heating isn't just about your wallet.

This is the so what that really matters. It's about safety and reliability.

He mentions system failure.

Systems that are pushed too hard because of dirty filters or lack of maintenance, they're just more likely to fail completely. And again, they usually fail when they're under the most stress.

But there's something even darker. He brings up carbon monoxide.

Yes. This is a critical safety warning. We talked about how systems degrade, how that metal expands and contracts.

The fine wine thing.

Exactly. Your heat exchanger, the metal chamber where the fire burns, heats up and cools down thousands of times. It's like bending a paperclip back and forth. Eventually, the metal fatigues. It can crack.

And if it cracks, if it cracks.

Those combustion gases, including carbon monoxide, which is odorless and colorless, can escape the system and leak right into your living space.

That is a silent killer.

It is. And Cole is making the point that maintenance isn't just about saving 20 bucks on your bill. And it's about making sure the machine that is literally burning fossil fuels inside your house is doing it safely.

That really changes the perspective. It's not optional maintenance.

Cole's phrase is, with energy costs rising, efficiency isn't optional anymore. And I would add, safety isn't optional either. The stakes are just higher now.

It's a shift in mindset from I hope it works to I must ensure it works precisely.

You have to move from being a Passive occupant to an active homeowner.

So, as we wrap this up, let's recap the core message. The trifecta is real. Prices are up, it's cold, and our equipment is old.

But you can't control the weather. You can't control global energy markets.

You can only control the preparedness of your home.

That's the empowering part. You aren't helpless. You have levers you can pull.

I really like how he ended the piece, talking about luck.

Me, too. He says the homeowners who stay comfortable this winter won't be the lucky ones. We look at neighbors who are warm and think, oh, they're lucky their furnace is working. Cole says, no, that's not luck.

It's planning.

They are the ones who planned ahead. They handled the basics, got the tune up, changed the filter. They didn't wait for the coal to make the decision for them.

That's such a powerful takeaway, the idea that if you wait, the cold will eventually make the decision for you. And it is a cruel decision maker.

The cold doesn't care about your bank account. It doesn't care about your vacation plans. It doesn't care. It just exploits the weakness in your system.

So here's the final provocative thought I want to leave our listener with based on all this. If you are sitting there right now and your heating system is currently getting by, you know, maybe it rattles, maybe the airflow is weak, but it's working. Ask yourself this. Are you actually saving money by not calling a pro, or are you just deferring a much larger cost?

That's the question. Is it savings, or is it a loan with very, very high interest because you are going to pay it one way or another?

It's the difference between an investment in maintenance and the cost of a crisis.

Exactly. One you control, the other one controls you.

So what's the one thing they should do the second this deep dive ends?

Go check your air filter. Pause this. Walk over to the vent, pull it out. If it's gray, if it's fuzzy, change it. It is the easiest win you can possible get.

There you go. Don't let your meter spin faster than it has to. Thanks for listening to this deep dive. Stay warm, and we'll catch you next time.
