HVAC for coastal properties
Outdoor equipment lives in a demanding environment.
Sullivan’s Island homes deal with warm weather, humidity, wind-driven weather and salt exposure. Outdoor condensers and heat pumps benefit from regular inspection and maintenance, especially when corrosion, debris or airflow problems begin to develop.
The Town says repairs and improvements to residential or business property require building permits, and its fee schedule includes mechanical permits. Because the entire island is also within a Special Flood Hazard Area, equipment location and substantial improvements can involve floodplain requirements.

Comfort is more than temperature
If the house feels damp, uneven or stuffy, the thermostat may not tell the whole story.
An HVAC system can run and still leave a home uncomfortable. Uneven rooms, weak airflow, frequent cycling and excess indoor humidity can point to equipment, controls, ducts or sizing—not simply a temperature setting.
Before peak heat arrives
Maintenance is easier to schedule than a no-cooling call.
If the system is operating but has not been serviced recently, preventive maintenance gives a technician a chance to inspect operation, airflow, outdoor equipment and visible signs of wear before a failure becomes urgent.

Common HVAC questions
What Sullivan’s Island homeowners ask about heating and cooling
Do HVAC repairs or replacements on Sullivan’s Island require a permit?
The Town says repairs and improvements to residential and business property require building permits, and its fee schedule includes mechanical permits. Confirm the specific requirements for your project before work starts.
Is Sullivan’s Island entirely in a flood zone?
Yes. The Town states that all of Sullivan’s Island is within a Special Flood Hazard Area. Floodplain rules can affect substantial improvements and the location or elevation of building equipment.
Why is my AC running but the house still feels humid?
Possible causes include airflow, controls, equipment operation, duct conditions or system sizing. Report both the temperature problem and the humidity problem when requesting service.
Should I repair or replace an older HVAC system?
That depends on the failure, age and condition of the equipment, repair cost and broader system performance. For an expensive repair, asking for both repair and replacement options can make the decision clearer.
What should I tell an HVAC company when I request service?
Describe whether the system is cooling or heating, any sounds or odors, thermostat behavior, rooms that feel different, how urgent the issue is and anything you know about the equipment.
Do heat pumps provide both heating and cooling?
Yes. Heat pumps can provide both cooling and heating, so a heat-pump problem can affect comfort in more than one season.
