Dunell Do All HVAC Services · Myrtle Beach, SC
AC quitting in a Grand Strand heat wave or heat out on a cold snap — Dunell Do All shows up on time, quotes the price before the work starts, and does it all: heating, cooling, refrigeration, and maintenance repair.
We've been there
The vents blowing warm in July. The furnace quitting on the coldest night of the year. That's the call Dunell Do All is built for — answered by a real person, fixed the same day in most cases.
What we do
One crew for heating, cooling, and refrigeration — from a capacitor swap to a full changeout, residential and light commercial.
Diagnostics on all makes and models — refrigerant leaks, failed compressors, frozen coils, weak airflow. Fixed right the first time.
Ignition failures, short-cycling, blower motors, heat pumps in defrost lockout. Carbon-monoxide safety check with every visit.
Right-sized systems with a load calculation — not a guess. Straight talk on repair vs. replace, financing available.
Duct sealing and repair, media filters, UV purifiers, and humidity control for rooms that never seem to get comfortable.
Walk-in coolers and freezers, reach-ins, prep tables, and ice machines — emergency repair before your stock is at risk.
Rooftop units, split systems, and preventive contracts for shops, restaurants, and offices — with after-hours scheduling.
