HVAC Company in St. Augustine South, FL

Dalton Heating & Air handles HVAC repair and installation across St. Augustine South, FL, with written pricing before any work starts and a full-year written guarantee on every repair. Homes here sit close to the Matanzas River and the Intracoastal, which means salt air moves through outdoor condenser coils faster than it does inland, and the cooling season runs long enough that small problems turn into bigger ones unless they’re caught early. Call (361) 306-9515 when your system stops holding temperature or makes a sound it didn’t make last month.

Why St. Augustine South Homes Are Different

St. Augustine South was built largely in the 1950s and 1960s, and the housing stock reflects that era: concrete block construction, original duct runs in many homes, and electrical panels that were sized for a window unit or two, not today’s central air. When we open a condenser or air handler in this part of town, we expect to find older return-air setups and duct joints that have loosened over decades of humidity. That’s not a knock on the homes. It’s just what the work looks like here.

The salt air is the quiet variable. Outdoor units within a mile or two of the river show coil corrosion earlier than units ten miles inland, and the fins on a Goodman or Trane condenser will start to flatten and crust if they’re not rinsed. Drain lines also clog more in this climate because the system runs hard from April through October. A homeowner who gets a tune-up in early spring catches the condenser issues before the first 90-degree week. The flat, low terrain west of US-1 means water sits after storms, and outdoor units on ground pads near drainage swales need a few inches of clearance or they’ll pull moisture into the cabinet.

Permits are straightforward for repairs and most replacements in St. Augustine South, but any new install that changes the electrical load needs a quick review from St. Johns County. We handle that on the front end so the job doesn’t stall at inspection.

Our Main St. Augustine South Services

Most calls we take in St. Augustine South are for one of three jobs: a system that quit cooling, a heat pump swap, or a furnace that won’t fire on the few cold nights we get. Each has its own page with pricing, timelines, and what to expect.

AC Repair in St. Augustine South

When a central air system stops cooling in St. Augustine South, the cause is usually one of three things: a failed capacitor, a refrigerant leak at a braze joint or coil, or a clogged condensate drain that tripped the float switch. Our techs carry capacitors, contactors, fan motors, and drain-line parts in the truck, so most repairs finish the same day we’re called. The salt air here means we check for coil corrosion on every call, even when the reported problem is something else. Pricing runs $150 – $650 depending on the part and labor, always in writing before we start. AC Repair in St. Augustine South

Heat Pump Installation in St. Augustine South

Heat pumps work well in St. Augustine South because our winters are mild enough that the system never has to strain, and the same unit that cools in August also heats on the cold dips in January. An install here usually means removing an older straight-cool condenser and air handler, adding or upgrading the line set, and sometimes bringing the electrical disconnect up to current code. The work is load-calculated per home, not guessed from square footage, and we set a written install date before any equipment is ordered. Heat Pump Installation in St. Augustine South

Furnace Repair in St. Augustine South

Furnaces in St. Augustine South sit idle for most of the year, which creates its own set of problems: igniters corrode from humidity, inducer motors seize after months without turning, and condensate traps on 90%-efficient units dry out and crack. When the weather dips into the 30s, those furnaces get called on hard for the first time since spring. Most furnace repairs run $150 – $700, and because the failure is almost always in a specific part rather than the whole unit, we repair furnaces rather than pushing a replacement. Every furnace repair carries the same written one-year guarantee as an AC repair. Furnace Repair in St. Augustine South
