Highlights
- Fast turnaround — one customer called at 3 PM, had crew by 8 AM
- Detailed cleaning process — plastics off, blower wheels removed and washed
- Accurate time estimates — quoted three hours for three units, on target
- Small crew size — reviews describe Derek and one assistant doing the work
One customer called Extreme Mini-Split Cleaning at 3 PM and had Derek at their door by 8 AM the next morning. That kind of turnaround, and Derek's name, run through nearly every review the company has. It describes itself as a family-owned deep-cleaning specialist for mini-splits, ductless systems, heat pumps, PTAC, HRV/ERV and A/C units, working out of Bedford and Dennis, MA to cover most of Massachusetts and southern New Hampshire. All 8 of its Google reviews are five stars, and every one is from 2026. They're specific rather than generic: one customer watched Derek strip both mini-splits down to the coil — plastics off, blower wheels pulled, everything scrubbed and rinsed — and finish two units in about two hours. Another got a time estimate of three hours for three units and said it landed right on target. A third had the service recommended by a mold inspector for allergy reasons and noticed fresher air the same day. The crew is small — reviews describe "Derek and his very able assistant" handling the work themselves, not a larger outfit — which is worth keeping in mind if you're trying to book during peak season, even though the reviews on file describe fast scheduling. Nothing in the record raises a pricing or workmanship complaint; one reviewer called the price reasonable for the level of work. For a mini-split or ductless system that hasn't been opened up in years — or a household dealing with allergies or a musty smell when the unit kicks on — this looks like a solid call. Confirm the current wait time when you book, since the fast responses on file may reflect a slower season.
