I'm thinking of fitting an MD Central Vac.

I don't have an attached garage so will have to fit the power unit in a cupboard in the kitchen. It's ventilated.

Do you think it will be annoyingly noisy? I'm told that central vacs are quieter these days. Is this true?
 
I don't know about MD central vacs but my grandmothers Fasco mastervac II from 1993 was really loud and when it died last summer she got a new Vacuflo FC650 and it is quieter then the old one but it is a little loud. Hope this helps

My MD central vacuum is significantly quieter than the Dirt Devil Pro Series it replaced. I actually don't think it would be any louder than a canister vacuum if you were to keep it in a ventilated closet/cabinet.
 
Thank you for your help guys 😁

I'll risk it. Supposed to be 65db so I guess that isn't too loud. I hope not anyway.

The garage isn't far away. I was considering running pipes under my lawn but I was advised not to as it could lead to problems?
 
If the ground

gets too cold or too hot, the pipes could crack. My guess is if the ground doesn't change in temp. more than 20 degrees C or F., and doesn't freeze, you'll be ok burying them. Lawn sprinkler lines crack all the time around here even though owners have them air evacuated every fall before the ground freezes.
 
What about condensation?

We don't get severe weather here.Cant remember the last time it was very hot or very cold. Plenty of rain tho. I'm developing webbed feet!

So you think it would be better to put it in the garage as it may be a bit noisy in a ventilated closet?
 
I Put an MD Silentmaster

In a hall closet in my home in LA. No basement and a detached garage. I originally had a regular MD unit but my partner worked from home and the unit was next to his office. Way too loud for him when the housekeeper was there twice a week. Replaced it with a Silentmaster and problem solved. Those Silentmaster units are perfect for closet installations. Very quiet.
 
condensation?

Good question. There shouldn't be much. I wonder if a Lamb bypass 2 stage motor is tough enough to handle it.
Mine has been in my garage exposed to condensation for sure for over 20 years.
Some light rust inside the dirt canister, but that's it.
An exhaust muffler will fit any unit. The Beam serenity series uses that, plus an insulated vented plastic cover on top.
I added a muffler to my Hoover, and it makes a big difference.
 
If you lay the pipes underground can you get condensation inside them? That would trap the dirt wouldn't it?
 
The condensation occurs anytime the air you're sucking through the pipe is a lot warmer than the pipe itself. The dirt then sticks to the wet inside of the pipe, which gradually clogs and needs to be cut out and replaced. Dirt + water = concrete! I see it all the time around here with piping that runs uninsulated through attics. Bad idea if you ask me, especially if you have cold winters. If not, there would be a way to do it, but no doubt costly and labor-intensive.

Better to install the unit into a soundproofed cabinet and pipe the exhaust outside. The Flo-Master F650T is a very good and quiet unit, plus it's compact and filters tremendously well.
 
It depends on which kind you would get because some are noisier than others and some are quieter than others. We sell Simplicity and MD central vacuums because not only they are ridiculously powerful but they are also extremely quiet. If you're going to get an MD, go for the Silentmaster lineup because they're quieter than the other MD models such as the Flo-Master, Air Force, Modern Day, and Air Master.

If you do bury the pipes, be sure to go deep enough that it's below the frost line and put the pipe and wire inside of a larger pipe. This is supposed to prevent the central vac tubing from being crushed, cracked, or causing condensation.

I have a Honeywell central vac/made by Electrolux Home Care Products/same company that owns Beam.
It's not unbearably loud being in the same room as it, but it is vented outside. Being near the exhaust while it's running is almost unbearable.

Our exhaust vent is on the back of our house and you can ver clearly hear it from the front of the house. You can't hear it much inside though.
