MD equipment. Local guidance. Long-term support.
AceVacuums helps customers select, install, maintain and repair MD central vacuum systems in Northern Virginia, Washington, DC and Maryland. Visit our Fairfax or Leesburg showroom for model and accessory guidance, or call to discuss an installed system.
Here, MD refers to the central vacuum manufacturer; Maryland is part of our service area. Have the exact power-unit model ready so we can separate equipment selection from parts compatibility.
Explore the MD range
SilentMaster
Compare the specific model’s electrical requirements, collection arrangement and performance against your home and cleaning tools.
ModernDay
Review the exact model and voltage when planning a new system or replacing an older power unit. Similar model names can have different requirements.
Flo-Master & AirMaster
Identify the full model designation before comparing replacements or ordering service parts. Availability varies by model.
These catalog examples are starting points for comparison. Check each listing and confirm availability; the power unit may be supplied separately from hoses and tools.
A better MD recommendation starts with four details
Home & reach
Approximate floor area, levels, distant rooms, existing inlet positions and the hose length you need.
Floors & tools
Hard flooring, carpet type, pet hair, stairs and the electric or air-driven head you intend to use.
Existing equipment
Model-label photo, mounting space, pipe connections, electrical supply and current hose and inlet photos.
Also tell us how you want to manage hose storage and routine emptying. We can discuss suitable options after reviewing the installation requirements.
Replacing an older MD, Beam, NuTone or another unit?
An existing pipe network may be reusable, but the new unit must suit its condition and layout. Check the mounting bracket, intake connection, exhaust route, control wiring and electrical requirements before ordering.
Do not assume that a 120-volt model and a 240-volt version are interchangeable. Required electrical changes belong in the installation scope.
Review installation optionsAlready own an MD system?
| Your need | Start with | Useful information |
|---|---|---|
| Weak suction | Suction troubleshooting | One inlet or every inlet; maintenance history; hose condition. |
| No start or intermittent operation | Startup troubleshooting | What the normal unit controls do; indicator lights and symptoms. |
| Bags, filters or service parts | Model-to-part directories | Full model label and photos of the existing part or bag connection. |
| Routine care | Maintenance service | The owner’s manual and the current collection/filter arrangement. |
MD repair assessment: describe weak suction, intermittent starting, unusual noise or a hose or floor-tool problem. We review the power unit alongside the connected piping, inlets and accessories before discussing compatible parts or replacement. Stop using equipment that smells burnt, sparks or repeatedly trips a circuit, and leave electrical covers closed.
See the installation beyond the power unit
A power unit is only one part of the project. This AceVacuums field clip shows central vacuum piping and an inlet under construction; it illustrates installation access, rather than a specific MD model.
For an MD installation or upgrade, we review the equipment and connections together. The route, controls and inlet arrangement need to fit the intended system.
Hoses, floor tools, bags and warranty questions
Match a replacement hose to the wall inlet, activation method and carpet head. Check pigtail or direct-connect electrical arrangements before buying an electric kit.
Bags and filters must match the exact unit and collection arrangement. Use the model-specific manual; do not order by the MD brand name alone.
For warranty questions, bring the purchase record, model and serial number. Coverage, exclusions and any labor or travel charges depend on the applicable terms and the assessment.

Frequently asked questions
Which MD central vacuum model should I choose?
Start with the home layout, piping, flooring, hose type, electrical supply and service access. AceVacuums can help compare specific models after reviewing those details.
Can you help with an older SilentMaster or ModernDay?
Call with the full model designation and symptoms. Repair options depend on diagnosis, unit condition and compatible parts availability.
Can an MD unit replace another brand?
It may be possible to reuse suitable piping and inlets. Mounting, controls, voltage, intake, exhaust and overall system condition must be checked first.
Do all MD models use the same bag?
No. Match the exact power unit and collection arrangement to the correct bag or filter. The model label and a photo of the existing fitment are useful.
Can I see a model at the showroom?
Call Fairfax or Leesburg before visiting to confirm which models and demonstrations are currently available.
Do you support customers in Washington, DC and Maryland?
Yes. AceVacuums supports the DMV area from its Fairfax and Leesburg showrooms. Confirm your address, service coverage and appointment arrangements when you call.
Can an MD central vacuum be installed in an existing home?
A retrofit may be possible if the home has suitable pipe routes, inlet locations and space for the selected power unit. Share the layout and access photos. The installation guide explains the assessment and scope questions.
How often should I service my MD central vacuum?
Follow the owner instructions for the exact model and collection arrangement. Usage and debris load affect bag and filter care. Changes in suction, sound or operation should be assessed when they occur; a fixed interval cannot be applied to every MD system.
