If you’ve ever lived in a mobile home, you know that the furnace is usually right there in a closet off the hallway. That means when it kicks on in the middle of the night, you’re going to hear it.
So, if you’re looking at the Revolv MG1E 80 AFUE 56,000 BTU furnace, you might be wondering:
👉 How loud is it?
The short answer: The Revolv MG1E is about as quiet as any standard single-stage mobile home furnace. It’s not whisper-silent like some high-end variable-speed models, but it’s also not the roaring metal box you might remember from decades past.
Let’s break down the details — from how furnace noise is measured to real-world noise levels, brand comparisons, and Tony’s tips for keeping things as quiet as possible.
📖 Why Furnace Noise Matters in Mobile Homes
Noise is a bigger deal in mobile homes than in traditional houses. Here’s why:
-
Smaller spaces → You’re closer to the furnace no matter where you are.
-
Utility closets → Furnaces are often installed right off the hallway or near bedrooms.
-
Thinner walls → Less sound insulation compared to stick-built homes.
That means even a normal-level hum feels louder because it’s happening right in your living space.
👉 For mobile home owners, quiet operation isn’t just a luxury — it’s a comfort factor that affects daily life.
🔊 How Furnace Noise Is Measured
Furnace noise is measured in decibels (dB). Here’s a quick guide to put it in perspective:
-
30 dB → Quiet whisper
-
40 dB → Refrigerator hum
-
55–65 dB → Normal conversation
-
70 dB → Vacuum cleaner
-
80 dB → Garbage disposal
Most furnaces fall somewhere between 55 and 70 dB, depending on blower speed, cabinet design, and installation quality.
👉 The key isn’t just the decibel number — it’s also whether the sound is steady or fluctuates. A steady hum fades into the background, while rattles or squeals get on your nerves.

🎛️ Noise Levels of the Revolv MG1E
The Revolv MG1E is a single-stage, downflow mobile home furnace. That tells us a few things about its sound profile:
-
Single-stage blower: Runs at full speed when on. This makes the sound steady but not as quiet as variable-speed systems.
-
Cabinet insulation: Revolv builds its units with vibration-dampening cabinets, which helps keep the noise down.
-
Typical range: 55–65 dB (about the same as a conversation).
What That Means in Real Life
When it kicks on, you’ll hear a low “whoosh” as the blower pushes air down into the ducts. If you’re standing in the hallway, you’ll notice it. But once you’re in the living room or bedroom, it’s more of a steady background hum.
👉 In my experience, it’s quieter than the old Coleman furnace I replaced, which rattled like a washing machine on spin cycle.
⚖️ Revolv vs. Other Mobile Home Furnace Brands
So how does Revolv stack up against its competitors?
Revolv MG1E (by Style Crest)
-
55–65 dB
-
Single-stage blower
-
Affordable, reliable sound level
Miller & Intertherm
-
55–65 dB (same as Revolv)
-
Also use single-stage blowers in their 80 AFUE models
-
Noise levels nearly identical in real-world installs
Coleman (High-Efficiency Models)
-
50–60 dB for variable-speed units
-
Quieter when running at low capacity
-
Costs more, but you get a softer sound profile
👉 Bottom line: Revolv, Miller, and Intertherm are on par. If you want a quieter variable-speed blower, you’ll need to jump into higher-efficiency Coleman models — and pay for it.

🏡 Factors That Affect Perceived Noise
Not all furnace noise comes from the unit itself. How it’s installed and maintained plays a big role.
1. Closet Location
If your furnace is near bedrooms, you’ll hear it more than if it’s closer to the living room.
2. Closet Insulation
Bare drywall closets amplify noise. Adding insulation or soundproof panels helps.
3. Ductwork Condition
Leaky ducts create whistling or hissing sounds. Loose ducts can rattle.
4. Filter Type
Overly restrictive filters force the blower to work harder, increasing noise.
👉 My take: A properly installed Revolv MG1E sounds quieter than a poorly installed Coleman.
🔧 Tips to Reduce Furnace Noise
Here are some easy ways to keep your Revolv furnace running smooth and quiet:
-
Change filters regularly. A clogged filter makes the blower strain (and louder).
-
Seal ducts. Prevents hissing and air leaks.
-
Add insulation. Line the furnace closet walls with sound-absorbing panels.
-
Check plenum seal. If the furnace isn’t sealed to the plenum, air leaks will create whistling noises.
-
Use vibration pads. Placing the furnace on rubber isolation pads reduces cabinet hum.
👉 Pro tip: Don’t oversize your furnace. A unit that’s too big will short-cycle, meaning it starts and stops more often, creating more noise overall.

👨🔧 Tony’s Take on Noise
Here’s the honest truth:
“The Revolv MG1E isn’t silent — you’ll know when it’s running. But it’s steady, not obnoxious. I’d rather have a consistent hum than a furnace that rattles, whistles, or kicks on and off every few minutes.”
In my own home:
-
I hear it when I’m in the hallway.
-
In the living room, it fades into background noise.
-
At night, I actually like the hum — it’s like white noise.
If noise is your top concern, you can spend more for a variable-speed model. But for most homeowners, the Revolv’s sound is normal and easy to live with.
📊 Noise Level Comparison Chart
Here’s how the Revolv MG1E stacks up:
| Sound Source | Noise Level (dB) |
|---|---|
| Whisper | 30 dB |
| Refrigerator Hum | 40 dB |
| Revolv MG1E Furnace | 55–65 dB |
| Normal Conversation | 60 dB |
| Vacuum Cleaner | 70 dB |
| Garbage Disposal | 80 dB |
👉 So, yes — you’ll hear it. But it’s not louder than everyday life in your home.
✅ Final Takeaway
-
The Revolv MG1E furnace runs at 55–65 dB, about the level of normal conversation.
-
Noise is comparable to other mobile home furnaces like Miller and Intertherm.
-
Coleman’s high-efficiency models can be quieter — but cost more.
-
Installation quality, duct condition, and filter maintenance matter just as much as the brand.
-
Tony’s rule: “If it’s a steady hum, it’s normal. If it rattles, squeals, or whistles, it’s time to fix something.”
👉 Bottom line: The Revolv MG1E is quiet enough for comfort in a mobile home, especially if you stay on top of basic maintenance.
