Do you clean mini-splits in multi-unit buildings?

Yes, and most of our Brighton work is exactly that - triple-deckers, two-families, condo buildings and small apartment buildings. We can do a whole building in one visit or schedule unit by unit around tenants. Every head gets photographed before and after, so an owner or association has a record of what was done in each unit.

We converted from a gas boiler to heat pumps. Does that change the cleaning schedule?

Yes. Once the heat pumps are carrying the heat as well as the cooling, the system runs twelve months a year instead of three. That is roughly four times the hours through the same blower wheel, so it needs cleaning sooner than a cooling-only install.

How often does a mini-split need deep cleaning?

Every two years for most homes, and sooner in a rental or a busy apartment where the system runs long hours. Sooner again with pets, or if the system runs year-round for heat, or if there is a smell on start-up.

Why Brighton Runs on Mini-Splits

Brighton's mix of wooden triple-deckers, older two-family homes, brick apartment buildings and converted condominiums makes ductless heat pumps a practical choice. Many of these buildings went up long before modern central air conditioning, and installing full ductwork is difficult without opening ceilings, walls or shared areas. Mini-splits let property owners and condo associations add efficient heating and cooling one apartment or one zone at a time.

Brighton is also seeing older multifamily properties converted from gas boilers to electric heat-pump systems, while new development is increasingly designed as all-electric from the start. That shift changes the maintenance picture. A unit that only ran for air conditioning in July and August now carries the heat too, which means twelve months of run time through the same blower wheel instead of three.

And because so many of these systems serve busy apartments and rental units, they operate for long hours year-round. Deep cleaning the blower wheel, coil, drain pan and filters keeps airflow up, holds musty odors down, and keeps each indoor unit working efficiently for the people living under it.

A Mitsubishi wall unit in a Brighton multifamily. The coil and drain pan were loaded, and the blower wheel had gone black right through.

What a Deep Clean Includes

Full teardown of each indoor head — blower wheel, evaporator coil, drain pan and condensate line cleaned properly, not wiped. Outdoor unit rinsed. Filters inspected and cleaned or replaced. System tested before we leave, and you get photographs of every unit before and after.

The head stays on the wall. We bib the unit, drop-cloth everything underneath and run the wash water into a bucket — so what comes off the system ends up there and not on a wall, a floor, or a tenant's furniture.

For Owners, Landlords and Condo Associations

A three-family with six heads is a very different job from a single house, and it gets scheduled that way. We can take a whole building in one visit, or work unit by unit around tenants' schedules.

Every head is photographed before and after, so an owner or a board has a record of what was actually done in each apartment — useful at turnover, useful when a tenant reports a smell, and useful when the association has to show the work was done.

Questions We Get in Brighton

Do you do whole buildings?

Yes. Triple-deckers, two-families, condo buildings and small apartment buildings are most of what we do here. Pricing is per indoor and outdoor unit, so a building with more heads gets a better rate per head — the calculator will show you.

Why does my mini-split smell musty when it starts up?

That smell is almost always the blower wheel. It's the barrel-shaped fan behind the vanes, and it stays damp through the cooling season because that's where condensation forms. Dust sticks to it, the damp keeps it there, and mold grows on the wheel and down into the drain pan underneath. Nothing you can spray in the vents reaches it — it has to come apart.

We went from a gas boiler to heat pumps. Does that change anything?

Yes, and it's one of the most common Brighton situations now. Once the heat pumps carry the heat as well as the cooling, the system runs twelve months a year instead of three — roughly four times the hours through the same wheel. Those systems need cleaning sooner than a cooling-only install, and most owners don't realize the schedule changed when the boiler came out.

Can you work around tenants?

Yes. A head takes about an hour. We bib the unit, drop-cloth everything underneath and carry the wash water out, so the apartment gets left the way we found it. Access and parking in Brighton is the part worth planning — tell us what the building is like when you book and we'll work around it.

How much does it cost?

It depends on how many indoor and outdoor units you have. The instant price calculator gives you a real number in about thirty seconds — no phone call, no waiting for a quote.
