Is R-54 overkill for a drafty house in Cleveland?

Spending roughly $1,800 to hit R-54 with blown-in cellulose is absolutely worth it, especially with Cleveland winters. I was in a similar spot with high gas usage and a second floor that felt like a walk-in cooler. Bringing the attic up to that standard stops the heat from just radiating trough the ceiling, which is exactly why your upstairs feels so much colder than the main floor right now. It finally balances out the temperature because the furnace isn't constantly fighting a losing battle against the attic floor.

You definitely need a contractor who handles **air sealing** and rafter vent repair as part of the package. Most reputable insulation guys will fix those baffles or install new ones before they blow the cellulose in. If those vents are blocked, your attic can't breathe, which leads to moisture buildup and those nasty ice dams. But properly installed vents also ensure the insulation stays effective by keeping the roof deck cool and preventing heat from being trapped where it shouldn't be. The savings aren't just a guess; I saw my gas bill drop by about 25% almost immediately. Even with energy prices jumping around, the actual Ccf usage went way down. Plus, there is often a federal tax credit for weatherization that can knock a few hundred bucks off the total cost if you file the paperwork. It usually pays for itself in under three years, but the fact that you can actually sit upstairs comfortably is the real win.

Don't worry too much about the windows being the primary culprit yet. While old windows aren't great, the stack effect in a house means most of your heat is escaping through the top. Plug those leaks in the attic and beef up the R-value first. You’ll notice the furnace cycles way less often, which is going to save your HVAC system from premature wear and tear in the long run.

Have you ruled out the weather being milder this year? Cleveland winters vary a ton, and even a small shift in average outdoor temps can relly skew those Ccf comparisons. Also, did you happen to get a furnace tune-up or change your filters right when the work was done? Sometimes we give all the credit to the cellulose when small mechanical tweaks are doing some of the heavy lifting. I’d be curious to see if that 25% savings actualy holds up when we hit a truly brutal month.

I'm totally stoked to hear about these results! I've been lurking for a week and seeing a real-world 25% drop makes me want to call a contractor right this second. It's crazy how much of a difference it makes. Since you mentioned the cellulose, does anyone know if adding that much material can actually hurt old ceilings? I've got original lath and plaster in my place and I'm super paranoid that the weight of R-54 or higher might cause some sagging or new cracks. Is that something people usually check for before blowing it in?

One thing I noticed after doing my R-50 blowout was how much quieter the house got. I used to hear the wind rattling the soffits, but now it's dead silent upstairs. If you haven't yet, grab one of those insulated tent covers for the attic hatch. I didn't realize how much heat I was losing right thru that thin piece of plywood untill I felt the draft go away. My furnace cycles way less now, especally at 3 AM when the temps realy dip. It's those small gaps like the hatch and around the light fixtures that'll kill your efficiency if they aren't plugged.

Wait'll summer hits, that's when you'll really feel the difference. Everyone focuses on the heating bill, but keepin' the upstairs cool in July is a total game changer. My AC used to run 24/7 and still couldn't keep up, but now it actually cycles off like it's supposed to.

Did your guys check the recessed lights? If those aren't IC-rated and they didn't box 'em out, that's usually the one spot where heat still sneaks trough.

Quick update—the R-54 blowout was a game changer. Someone mentioned the house getting quieter and they were spot on; the wind noise is totally gone now. I also took the advice to get an attic hatch cover, wich stopped that last draft. My gas bills dropped even more than I hoped, hitting that 25% goal easily. If you're on the fence, just do it.
