Taking calls now·Talk with someone about your HVAC needs
Most of the calls we answer come down to two things: a house that won't cool, or a house that won't heat. Here's how we handle both.
A dead air conditioner on a hot afternoon is the call we run most. The usual culprit is a small electrical part, a capacitor or contactor, that our trucks carry, so most AC repairs are finished in one visit. Pricing is upfront, and we'll tell you honestly whether a repair is worth it on an older unit.
When the furnace clicks but never lights, lights and shuts off, or runs without warming the house, the cause is usually one component. We test the ignition, airflow, and safety controls to find it. You'll get a clear quote first, plus a safety check of the combustion and venting while we're there.
Wondering if it's bad enough to call? These are the most common heating and cooling problems we handle in homes across the area.
A system pushing warm air in summer is the call we run most. Our trucks carry capacitors, contactors, and motors to restore cooling same-day.
AC repairA furnace that lights and then shuts down within seconds usually has a dirty flame sensor or a failing igniter, quick fixes for an experienced tech.
Furnace repairWeak airflow at the vents points to duct restrictions, a struggling blower, or high static pressure. A tune-up finds it before it kills the motor.
Maintenance & tune-upsA system past 12 to 15 years that needs a repair every season is telling you something. We'll give you the honest math on repair versus replacement.
System replacementA musty smell at startup often means moisture in the ducts or a dirty evaporator coil, worth addressing before it becomes a bigger air-quality problem.
Air duct cleaningMini-splits deliver precise heating and cooling to a single zone, run whisper-quiet, and sip electricity compared to window units.
Mini-split installationAn HVAC system never fails at a convenient time. We schedule fast, show up on time, and arrive with the parts to finish the job.
Experience is what separates a lasting fix from a temporary one. Our technicians have spent years reading these systems, refrigerant behavior, combustion, airflow, electrical faults, and matching the repair to the actual cause.
You'll get a clear written quote before any work starts, and the price you approve is the price you pay. That's why so many customers call us back.
A proper repair includes the details: static pressure check, capacitor test under load, combustion analysis on furnaces, and a clean condensate path that won't back up in August.
Year after year, St. Augustine HVAC has been the team local families call when the AC quits or the furnace goes cold. We've serviced systems in nearly every neighborhood around town, and that track record shapes how we approach each job, from the first diagnostic to the final test.
Knowing St. Augustine is half the job. We've learned which neighborhoods run undersized ducts, how the local climate loads systems season to season, and what inspectors here look for on permits, and we put that knowledge to work on every job so it's done right the first time.
Call a local HVAC expert. Upfront pricing, no obligation.
From the first call to the final airflow check, our method is built to solve the problem completely the first time.
Call (904) 243-4271 and we'll get you a price quote, often within a day. A few quick questions, cooling or heating, what the system is doing, how old it is, and we'll book a time that works for you.
We inspect the whole system, not just the obvious symptom, and give you a straight answer: what failed, why, and what repair versus replacement really costs.
Whether it's a ten-minute capacitor swap or a full system changeout, the work is done carefully, tested thoroughly, and left cleaner than we found it.
To keep your comfort reliable long-term, we can set up seasonal maintenance that cleans coils, checks the charge, and catches small issues before they strand you in the wrong season.

There's no mystery to how we handle an urgent failure. Here's the step-by-step of what we do after a homeowner calls for fast help.
When you call (904) 243-4271, you reach our local team directly. We listen to what's going on, note the details that matter, and get you on the books, often within hours, with quick guidance on what to do until we arrive.
Right away, our fully equipped technician is on-site with everything needed to diagnose and begin the repair in your property.
The fault is identified, capacitor, motor, refrigerant leak, control board, or the compressor itself. Then, we complete the repair on the spot whenever parts allow, or quote the replacement with real numbers if the unit is done.
We verify the fix held and answer any questions after the visit. This is also when we set up seasonal tune-ups to extend the system's life, which is the cheapest comfort insurance there is.
"Half our house was always five degrees warmer than the thermostat said. The tech rebalanced the dampers and fixed a kinked duct run, then set up a new smart thermostat and actually taught us how to use it. Every room finally feels the same."
"From the estimate to the final walkthrough, the whole install was smooth and organized. The crew wore shoe covers, put down drop cloths, hauled off the old equipment, and the final bill matched the quote to the penny. The new system is so quiet we barely notice it running. Highly recommend."
"Our restaurant's rooftop unit failed on a Friday with a full weekend of reservations booked. Their team got it running the same day. They clearly understood what downtime costs a St. Augustine business, and they came back the next week to fully service the second unit. They've got all our locations now."
We treat your home the way we'd treat our own: thoroughly, honestly, and with an eye on the long term. Here's the standard you can count on from us every time.
We don't send a rookie with a gauge set and a hope. Each technician brings genuine field experience in diagnosis, safe gas and electrical work, and clean installation, the kind of depth that turns a service call into a lasting fix.
We size every replacement to your home's real heating and cooling load rather than defaulting to whatever's on the truck. Installations include the details that matter: correct gas and electrical work, balanced airflow, and full commissioning. You get a system that performs for years, not just on day one.
Our team believes in keeping systems alive with inexpensive seasonal care. If you want to avoid the emergency replacement, our spring and fall maintenance visits handle the checks that actually extend equipment life. No surprises, no hidden fees. This focus on longevity is why so many homeowners recommend us.
Wherever you are in our service area, we've got it covered, with fast repairs, quality installs, and maintenance plans reaching every community on our list.
