Air conditioning and heating in Brunswick, GA

Brunswick sits a few miles back from open water, so condenser coils here corrode slower than anything on St. Simons or Sea Island. Twice-a-year maintenance is genuinely enough for most of town, and we do not pretend otherwise to sell you a plan.

The exception is anything east of US 17 and along the marsh edge off Blythe Island and the Sidney Lanier approach. Units backing onto the marsh get the same wet, brackish air the islands do, and we treat those on the island schedule: coil rinse and inspection three times a year instead of two.

What actually kills equipment in Brunswick proper is not salt, it is standing water and debris. Pine straw and oak litter pack the coil fins, drain lines slime shut in the humidity, and pads sink in yards that hold water after a summer squall. Half our Brunswick service calls in August are a clogged drain and a wet-switch trip, nothing more.

Glynn County runs dew points in the mid-70s for weeks at a stretch. That is latent load — moisture, not heat — and it is the reason an oversized system makes a Brunswick house feel worse. A 4-ton unit in a house that needs 3 tons satisfies the thermostat in eight minutes, never runs long enough to pull water out of the air, and leaves you at 72 degrees and clammy with mildew on the closet baseboards.

So we do a Manual J load calculation on the actual house — the real window area, the real attic insulation depth, the ductwork that exists — instead of matching the tag on the old unit. In older Old Town and Dixville houses, that number usually comes out smaller than what is sitting on the pad now.

We also care about how long the blower runs. Variable-speed equipment and a longer, lower-speed cycle is the single best money you can spend on comfort in this county, more than SEER numbers on a sticker.

From June through November we get calls about the same three things, and two of them are avoidable. Before a named storm turns toward the Georgia bight: cut power to the condenser at the disconnect, not just the thermostat, so a surge on a flickering line does not take the compressor or the board with it.

Do not tarp or wrap a running unit and do not stack plywood on top of it. Clear the two feet around it, move the grill and the potted plants, and strap the unit to its pad if it was never anchored — plenty of 1990s Brunswick installs are just sitting on a pad with no hurricane straps at all.

After the water goes down, if the condenser sat in standing or brackish water, do not switch it on. Call us first. We check the compressor windings and the contactor before power goes back to it, because a submerged unit that gets energized usually stops being repairable.

Old Town is 1890s to 1930s frame houses with tall ceilings, later ductwork stuffed into crawlspaces, and very little room to run a proper return. Those often do best as a right-sized system plus a dedicated dehumidifier, or high-wall mini-splits in the added rooms rather than one more branch off a duct trunk that cannot carry it.

Windsor Park, Oglethorpe Park, and the Altama corridor are mostly 1955–1975 brick ranches on slab, with attic air handlers and original R-6 flex that has been up there twice as long as it should be. Sealing and replacing duct in those attics regularly gains more than new equipment would.

Out past the mall and along Golden Isles Parkway the builds are 1998 onward, two-story, zoned badly or not at all, with an upstairs that runs six degrees hotter. Sterling and the county roads add propane furnaces and heat pumps on wells and long service runs. We have been in all of it for three generations, which mostly means we know what is in your attic before we open the hatch.
