Call Dad, LLC is committed to excellence in every aspect of our business. We uphold a standard of integrity bound by fairness, honesty, and personal responsibility. Our distinction is the quality of service we bring to our customers. Accurate knowledge of our trade combined with ability is what makes us true professionals. Above all, we are watchful of our customers' interests and make their concerns the basis of our business.

"I've had a service contract with them and their predecessor companies for a decade. I get up-sell pitches with each service visit since Call Dad. The last visit needed a condensate pump. They charged over $500 (this was already a semi-annual service visit under contract) and pitched a new igniter and capacitor at equally obscene markups. When I didn't renew the service contract, they removed the in-contract discount for the pump. I'm looking for a new HVAC contractor."

"Explained my issue to Austin Gas bill was almost double every month for all of 2025 as compared to the same months in 2024. The issue started soon after the tankless water heater was installed. To trouble shoot the potential gas issue, called Piedmont gas. William from Piedmont came out and tested ever appliance for stability and gas leaks. Nothing found. When checking the tankless water heater he found within seconds the water heater was running and no one in the house was using any water much less hot water. He said “That’s your problem. It’s running all the time causing your gas bill to go high“. Explained all this to Austin O’’Neal and he agreed. Made an adjustment and left. Even left me a video of what to do if I want to change it myself What GREAT. Customer service!! Who does that anymore??!! Thanks Austin "

FAQs for central a/c service or repair projects in Hickory, NC

Coils work to absorb heat into the refrigerant that flows through them, moving heat from one location to another. For air conditioning, the evaporator coil inside the air handler in your home absorbs heat. It then transfers the heat outside to the condenser coil, where it releases it. The opposite process happens for heat pumps. When the coils get dusty and dirty, it reduces how well these components work.

Skip regular cleanings, and dirt, debris, and mineral deposits will blanket your evaporator and condenser coils. When that happens, the coils can’t shed heat efficiently, so the system works harder and your energy bill climbs. Over time, overheating strains the compressor and can trigger a full breakdown—an avoidable repair that often costs far more than a simple annual cleaning.

AC coil cleaning is an investment that pays for itself in the benefits it provides. Dust‑caked coils force your AC to run longer, so you spend more on electricity and rack up extra wear. A quick professional cleaning restores efficiency, trims monthly bills, and eases strain on expensive parts. Over the long haul, that small yearly fee delays pricy repairs and stretches the unit’s lifespan, making coil cleaning one of the smartest HVAC tune‑ups you can schedule.

Watch for higher electric bills, rooms that stay warm no matter how low you set the thermostat, or an AC system that runs nonstop. Extra humidity and frost on the coils are also red flags. Catching these clues early lets you schedule a quick cleaning before the system overworks itself and triggers an expensive breakdown.

Your AC cleaning technician starts by shutting off the power to the unit and removing the faceplate. Compressed air and a vacuum hose blast away loose debris, followed by a coil-safe, no-rinse cleaner that dissolves stubborn grime. After the solution has soaked in, the professional wipes the fins, reassembles the housing, and restores power, leaving the system ready to cool at peak efficiency.
