Frequently Asked Questions
At D & S Heating & Cooling, we believe informed customers make better decisions. Below are answers to common questions we receive from homeowners in Beaufort, Lady’s Island, Port Royal, St. Helena Island, Seabrook, Bluffton, and Hilton Head Island.
We recommend servicing your HVAC system twice per year—once before cooling season and once before heating season. Regular maintenance helps prevent breakdowns and extends the life of your system.
In the Lowcountry, most HVAC systems can last 10–15 years. Coastal conditions like humidity and salt air can shorten lifespan without proper maintenance.
We work with a variety of HVAC systems including central air conditioning, ductless mini-split systems, heat pumps, and furnaces.
System size depends on factors like square footage, insulation, windows, and layout. A proper load calculation ensures your system is sized correctly for efficiency and comfort.
