A clogged filter pulled from a neglected return — six months of dust and pollen
Why it matters
Four problems, one visit
Skipping the deep-clean costs more than people realize. A neglected coil costs 15–30% more to cool. A clogged drain line floods your ceiling in July. A dirty blower throws dust through every room of the house. A spent filter makes all three worse. We catch all four at once — for less than a single emergency repair call.

How we do it
Methodical, step-by-step, no shortcuts
Power down at the disconnect. Pull and measure the filter. Vacuum the evaporator coil, then non-acidic foam, then rinse. Fin-comb every bent vane on the condenser. Pull the blower wheel, wipe each blade, spin-test the bearings. Clear both drain lines with a vacuum, flush with warm water, drop in a biocide tab. Power back on, verify refrigerant pressures and the temperature split, leave you the photos. That's the whole job — and we don't move on from a step until it's right.

What we use
Only what we'd use on our own homes
Plant-safe alkaline foam (not the acid stuff that pits aluminum and shortens coil life). Soft-bristle fin combs sized for your unit's fin spacing — bent fins get straightened individually, not crushed flat with a butter knife. HEPA-rated vacuums on the blower wheel so the dust we lift doesn't end up back in your air. Biodegradable biocide tabs for the drain pan. Everything we touch is the same tier we'd use on our own families' systems.

Cadence
Once a year, ideally in late spring
Best scheduled after the spring pollen peak but before the first heat wave — late April through early June for MetroWest and Greater Boston, running a bit later up in Midcoast Maine. A unit that gets this cleanup annually runs cleaner, fails less, and lasts 3–5 years longer than one that doesn't. Schedule it once and we'll remind you next year. Coastal or heavily-wooded properties may want a mid-summer touch-up; we'll flag it during your filter visits if we see fins clogging early.
Catch four problems in one visit.
