HVAC Coil & Blower Cleaning in Sanford, FL

Your evaporator coil and blower wheel are the heart of your HVAC system — and the dirtiest. A 1/8" layer of dust on the coil can cut efficiency by 20% and force the system to run 30% longer to hit the thermostat. We clean both, restore proper airflow, and most homes see a measurable drop in AC runtime within a week.

Bastion Duct Solutions provides air duct and dryer vent cleaning across Sanford and the surrounding Seminole County area — Historic Downtown Sanford, Lake Mary, Heathrow, Markham Woods, Lake Forest, and the Lake Monroe waterfront. The Sanford SERP is dominated by Orlando-radius operators (national chains and Orlando-radius operators) — most of them never set foot in a 32771 or 32773 home, charge $59 coupon prices, and upsell to $900 on-site. We're residential-only, give a firm written quote before any work starts, and document every register with before/after photos. Pollen, year-round AC runtime, and Lake Monroe humidity push Seminole County ductwork harder than the national 3–5 year average — most Sanford homes need a 3-year cycle.

4. Clean Blower Wheel: Remove the blower wheel, wash, and reinstall — this is where the dirtiest buildup lives.
5. Reassemble & Test: Reseal the access panel, restore power, and verify proper airflow and temperature drop.

HVAC Coil & Blower Cleaning FAQs — Sanford

Is this the same as an HVAC tune-up?

No — a tune-up is a check by an HVAC technician. We clean. We're the right call when your system is running but inefficient; call an HVAC tech for refrigerant, electrical, or mechanical repairs.

Will this fix a frozen AC line?

Sometimes — a dirty coil is one of the top causes of frozen evaporator lines. If freezing persists after cleaning, you likely have a refrigerant or airflow problem that needs an HVAC tech.

Should I do this with my duct cleaning?

Yes — bundling saves a service-call charge and the coil/blower are inside the same system we're cleaning anyway.

How long does it take?

1–2 hours for most residential systems. Larger multi-zone systems take longer.
