What Is EnergizeCT? A Homeowner’s Guide to Energy Savings and Insulation Incentives
If you're a homeowner in Connecticut and you like saving money (who doesn’t?), let me introduce you to EnergizeCT. It’s one of the best-kept secrets out there when it comes to making your home more comfortable and more energy-efficient—without draining your wallet.
So What Is It?
EnergizeCT is a state-backed program that helps homeowners and businesses cut down on energy use and upgrade their homes with rebates, incentives, and expert services. It’s funded by your utility bills (yep, you’re already paying into it), and it’s managed by folks like Eversource, United Illuminating, DEEP, and PURA. Translation: it’s legit—and if you’re not using it, you’re leaving free money on the table.
How EnergizeCT Helps Homeowners
Here’s what’s in it for you:
🏠 Home Energy Assessments
Through the Home Energy Solutions (HES) program, you can get a pro to come out, check where your home is bleeding energy, and fix small stuff on the spot. Drafty doors? Leaky attic? They’ll pinpoint it and start sealing it up—same day.
💸 Rebates for Insulation
This is the big one. EnergizeCT offers huge incentives for insulation, sometimes covering half or more of the cost. It makes upgrading to high-performance insulation—like our dense-pack cellulose—way more affordable.
🔥 Lower Energy Bills
Better insulation = less work for your furnace and AC. Less work for your furnace and AC = more money staying in your pocket every month. It adds up fast.
😌 Year-Round Comfort
No more frozen toes in February or sweating through your T-shirt in July. Proper insulation helps keep your house the same temperature everywhere, all the time.
🌍 You’re Doing Right by the Planet

How Much Money Will I Really Save by Upgrading my Insulation?
Let’s be honest—insulation isn’t sexy. It’s not something you show off to your neighbors. It’s not your renovated Kitchen with marble finishing or a beautiful new stone deck with a built in grill and smoker.
Let’s be honest—insulation isn’t sexy. It’s not something you show off to your neighbors. It’s not your renovated Kitchen with marble finishing or a beautiful new stone deck with a built in grill and smoker.
No one’s coming over to crack open beers and admire the craftsmanship… “Wow, check out that R-49 blown cellulose! There’s no lumps or anything!”
But… if you own a home in Connecticut, insulation might be the most boring way to save yourself the most money. You won’t get oooh’s and aaah’s but you will get lower energy bills, a more comfortable home, and fewer fights over the thermostat.
But I know what you’re now asking yourself… how much can I really save? How long does insulation take to pay for itself?
🥁🥁🥁
The Short Answer: 2 to 5 Years…
The Even Shorter Answer: It depends! But it does works
But definitely don’t take my word for it. What do I know, I’ve only been doing this for 40 years… And I’ve been told I’m biased or something…
Let’s see what the Research Says
According to the U.S. Department of Energy (DOE) and Energize CT, insulation and air sealing will shave 15–30% off your heating and cooling bills. In Connecticut, where winters are long and heating oil is basically liquid gold, that adds up!
- The average Connecticut household spends around $2,000 per year on heating and cooling combined (source: EIA.gov).
- So let’s do some quick math!
- If you saved 20% on your heating and cooling bills that’s $400/year back in your pocket.
- If your insulation project costs around ~$2,000 that’s about a 5 year payback
- If you save closer to 30%...that’s less than a three and a half year payback
- After that it’s just continuous money in your pocket for the next 25-30 years until you need another upgrade
But like I said before… it depends!
Not to brag or anything but we’ve upgraded homes in which the payback period was fewer than 2 years!
Add in Connecticut’s Home Energy Solutions program, and it gets better. The program can often cover up to 75% of the cost through rebates and incentives.

Why Does Insulation Lower Your Energy Bill?
Let’s start with this: insulation isn’t just a nice-to-have—it’s one of the most cost-effective ways to cut down on your energy bills year-round. Whether you’re battling a New England nor’easter or a brutal summer heatwave, your insulation is doing the quiet, thankless job of keeping conditioned air where it belongs: inside your home.

Whether you’re battling a New England nor’easter or a brutal summer heatwave, your insulation is doing the quiet, thankless job of keeping conditioned air where it belongs: inside your home.
But how does it actually save you money? Let’s break it down.
1. Insulation Slows Down Heat Transfer
Heat moves in and out of your house constantly—through walls, ceilings, floors, and anywhere it finds a weak spot. This process is called heat transfer, and without good insulation, your home is bleeding energy like a sieve. In winter, warm air escapes. In summer, heat pours in. Insulation acts like a barrier, slowing that process down so your HVAC system doesn’t have to work overtime to keep up.
Less work for your furnace or AC = less energy used = lower utility bills.
2. Insulation Keeps Temperatures Stable
Ever notice how some rooms feel freezing while others are sweltering? That’s usually a sign of poor insulation or air leaks. Ideally, rooms in the same house shouldn’t differ by more than 2–3°F. If you're seeing 5 degrees or more between rooms, it’s a red flag—your home likely has insulation gaps or airflow issues.
When you insulate properly—especially your attic, walls, and basement—you even out those swings and stop playing thermostat whack-a-mole. Want to layer your savings? Combine good insulation with simple, low-cost hacks to stay warm in winter—like these 10 free or cheap ways to stay warm.
3. It Reduces HVAC Runtime
Your heating and cooling systems cycle on and off all day. But the better your home holds its temperature, the less often those systems need to run. Over time, this adds up to serious savings—not just on energy, but also on maintenance and equipment lifespan. Well-insulated homes put less wear and tear on HVAC units, meaning fewer breakdowns and a longer system life.
4. It's a One-Time Investment That Pays Off For Years
Insulation isn’t a band-aid fix—it’s a long-term upgrade. Whether you’re using spray foam, batts, or blown-in cellulose, you’re making a one-time investment that keeps paying you back every month.
And if you’re looking to insulate finished walls without tearing everything apart, we’ve got a method for that too. It’s called drill and plug, and it lets us dense-pack cellulose insulation from the outside of your home—sealing up energy loss while leaving everything looking untouched. It’s one of our go-to moves for older homes with empty wall cavities.
The Bottom Line
If your energy bills are creeping higher and your home still doesn’t feel comfortable, your insulation might be the culprit. Fixing it won’t just make your house cozier—it’ll put money back in your pocket every single month.

Why Is Air Sealing Important?
Most people think insulation is the whole game when it comes to making a home energy-efficient. It’s a big part, sure—but if your house is leaking air like a drafty old barn, insulation alone isn’t going to cut it. That’s where air sealing comes in.

Think of insulation like a warm winter coat. Now imagine that coat has the zipper wide open and the wind’s whipping through. Not so cozy, right? Air sealing is the zipper. It keeps the conditioned air inside where it belongs—and the outside air out.
What Is Air Sealing?
Air sealing is the process of closing up all the tiny gaps, cracks, and holes in your home’s building envelope. These leaks might be around windows, doors, plumbing penetrations, attic hatches, recessed lights, or even your foundation. You don’t see them—but your energy bill sure feels them.
If you’ve ever walked into a room and it feels 10 degrees colder than the rest of the house, chances are you’ve got air leaks. Same goes for musty smells, moisture problems, or wild swings in your heating and cooling bills.
Why Air Sealing Matters
💸 Lower Energy Bills
Air leaks are one of the biggest causes of energy loss in the average home. Heated or cooled air escapes through those gaps, and your HVAC system has to work harder (and burn more money) to keep up. Air sealing can cut heating and cooling costs by up to 20% in some homes.

🌡️ More Consistent Temperatures
Ever notice that one room is always too hot in the summer or freezing in the winter? Air leaks are usually to blame. When you seal those gaps, airflow becomes controlled and consistent—no more temperature rollercoasters from room to room.
It’s especially important in the attic—one of the biggest culprits for leaks.
Our blog on blown-in insulation can help you identify the right insulation for your attic.
💧 Moisture Control
Air leaks don’t just move air—they move moisture. In the winter, warm indoor air rises and escapes through cracks in the attic. That moisture-laden air hits cold surfaces and condenses, which can lead to mold, mildew, and rot. Air sealing helps keep moisture where it belongs—and keeps your home healthier.
🧊 Works Hand-in-Hand with Insulation
Insulation slows down the transfer of heat, but it can’t stop moving air. That’s why insulation without air sealing is like buying an expensive cooler with the lid cracked open. You need both.
If your home feels drafty or your bills are creeping up, it could be a sign your insulation isn’t pulling its weight either. Here’s How to Tell If Your Home Is Under-Insulated
What’s the Air Sealing Process Actually Like?
Glad you asked.
Before we blow in any cellulose, we suit up and hunt down the leaks. Because once you’ve got 14 inches of fluffy insulation in the attic, going back to plug those gaps is like diving into a ball pit with a caulk gun—only sweatier and way less fun. Unless you enjoy spelunking through cellulose, seal it first.
🔧 What We Use
Our go-to is polyurethane insulating foam applied with a standard foam gun. It expands to fill cracks, cures fast, and sticks like a champ. Around wiring, pipes, light fixtures, and top plates? That’s where it shines.
And in basements—especially along the sill plate—we break out the big guns: rodent-resistant foam. This stuff is dense, durable, and keeps out everything from cold drafts to overly curious critters.
🔍 Where We Look
In the Attic:
- Gaps between drywall and top plates
- Around recessed lights and light fixtures
- Plumbing stacks
- HVAC duct penetrations
- Chimney chases
- Attic hatches
In the Basement or Crawlspace:
- All along the perimeter sill and rim joists
- Plumbing, electrical, and dryer vent exits
- Gaps where concrete meets wood framing
These are the usual suspects. Seal them up and you’re halfway to a tighter, more efficient home.
