AC Out Tonight: Who Takes After-Hours Calls
Air conditioning runs most of the year on the island, and a dead unit in July is an emergency, especially with guests in the house. E.A.C. Heating & Air says it answers calls 24/7, weekends and holidays included. Dyess Air & Plumbing, Gochnauer Air Conditioning & Heating and Gray’s Heating & Air Conditioning all advertise 24-hour emergency service, and TemperaturePro of the Lowcountry answers its phones around the clock. From Bluffton, Service Experts is open 24 hours.
Before you call, check the breaker and the thermostat batteries, and look at the drain line: a full condensate pan trips a float switch and shuts the system off. If the outdoor unit is humming but the fan isn’t turning, turn the system off at the thermostat so the compressor doesn’t overheat while you wait. Ask for the after-hours fee up front; some plans waive it for members.
What a New Heat Pump Costs on Hilton Head
Most island homes heat and cool with a heat pump, and a replacement is quoted per system, so a house with two or three systems gets two or three prices. What moves the price most: the size of the system in tons, its efficiency rating, whether the air handler and the outdoor unit are both replaced, whether ductwork or the line set needs work, and whether the outdoor unit gets a coastal-rated coil. A Town building permit is part of every replacement.
Get at least two written quotes for the same size and efficiency, and ask each company to measure the house rather than match the old unit, since many older island systems were oversized. Ask what the labor warranty covers and for how long, and whether the first year of maintenance is included. Gochnauer customers describe a whole system replaced in about six hours, and Dyess and E.A.C. both sell maintenance plans that start with the new install.
HVAC Maintenance Plans on Hilton Head
Island systems work hard: humidity, pollen and salt air clog coils and drain lines faster than inland. Most companies here sell a plan with two visits a year, one before summer and one before winter, plus a discount on repairs and priority when the phones are busy. TemperaturePro calls its plan ProPlan; E.A.C. describes two inspections and cleanings a year with repair discounts; Service Experts’ Maintenance+ carries no after-hours fees.
For a rental, a plan is the cheapest insurance against a lost booking. Ask whether the technician clears the condensate line and changes filters on each visit, and whether the company will meet guests at the house if the unit fails mid-stay.
Salt Air and Coastal Units
Salt in the air corrodes the aluminum fins and copper coils of outdoor units, so units close to the beach wear out sooner than those inland. Ask about a coastal-rated or coated coil when you replace an oceanfront or marsh-front system, rinse the outdoor coil with fresh water a few times a year, and keep shrubs a couple of feet back so it can breathe. Units on the ground in flood zones are often raised on a platform; ask the installer what the Town requires for your lot.
Every replacement, and most electrical and plumbing work tied to it, needs a Town building permit. See how to check a license before you sign a contract, or browse every trade on our home services page.
