AC Repair & HVAC Service in St. Augustine, FL

Masonry holds heat rather than resisting it, so a wall that took sun all afternoon is still releasing it into that room at nine at night. The equipment is usually fine and the room is simply being fed by a wall. We measure the supply air at that register before concluding anything about the system.

Usually by something added long after the building went up — window units, a retrofitted run through a closet, or ductless heads. Each of those has a different failure pattern, and the first job on a call here is often working out what somebody installed twenty years ago and why.

Closer to normal than it would be inland. A masonry building with no cavity insulation, near the water, in August, gives a system a great deal to do. What matters is whether it is keeping up while running, which is a measurement rather than an impression.

Yes, but where the outdoor equipment sits and what can be seen from the street are genuinely not your decision alone. We establish that before anything is ordered. It is the single most common reason a straightforward job here turns into a delayed one.

Frequently it is the best one, and occasionally it is the only one. Where you cannot open walls or lose ceiling height, a ductless head serves a room without asking the building to change. In larger or already‑modified buildings there are sometimes other routes, and we will lay both out.

Not if the humidity side is handled properly, which is the part people skip. Cooling a historic building hard while ignoring moisture is how plaster and timber get damaged. The right specification here manages humidity deliberately rather than treating it as a by‑product of cooling.

On Anastasia Island and out toward the beach, considerably. Salt settles on the outdoor coil and shortens its working life, and the closer you are the shorter it gets. Downtown it matters less than on the island, but it is never nothing this close to the inlet.

A full seasonal check‑over of the system you already have — measurements taken, the parts that genuinely foul cleaned, and a straight answer about what needs attention and what does not. In an older building it is also when we look at what the humidity is doing to the fabric. Cannot be combined with any other offer, one per household.

Yes, after a camera look first. Plenty of older buildings here have little or no ductwork, and some ducts only need a filter that seals. If yours do need cleaning, you get the price before any work starts. The details are on our St. Augustine air duct cleaning page.

That is humidity rather than temperature, and in a masonry building it is worth taking seriously, because the same moisture that makes a room smell is working on the plaster and the timber. Measuring humidity in a few rooms tells you whether it is the system, the building, or both.

Routinely. St. Augustine, Lincolnville, Anastasia Island, Davis Shores, Vilano and St. Augustine Beach are all inside the normal service area at the same pricing as anywhere else we go. Great Dane is licensed in Florida as CAC036942, which you are welcome to look up before you let anybody into the house.

Yes, and in these buildings it comes up constantly, because the instinct with anything this old is to assume everything needs replacing. Often what it needs is a setting, a seal or a humidity strategy rather than equipment.

Three things that cost nothing. Check the breaker for the air handler and for the outdoor unit. Look at the filter, because a collapsed one starves the system and imitates a far bigger fault. And note whether the problem is heat or damp — in a building like yours those are two very different visits.
