Why Trust Dalton Heating & Air Sandy Springs for Your Carrier HVAC?

Carrier builds good equipment. Infinity, Performance, Comfort, the Infinity 98 furnace, all of it. But a unit is only as good as the hands that service it, and Carrier systems have their own personality. The Infinity line runs on a communicating control loop. The Infinity 98 furnace modulates its inducer and gas valve in fine steps. The Comfort 14 is Carrier’s straightforward single-stage workhorse. If the technician doesn’t know which part talks to which board, you get misdiagnosis, wasted money, and a system that still doesn’t cool.

Marco Benitez, owner of Dalton Heating & Air Sandy Springs, picked up his fundamentals at Los Angeles Trade-Technical College before spending nearly two decades working systems across the Southeast. He and our techs have served Sandy Springs for years, including plenty of Carrier HVAC in Candler-McAfee, GA calls out near Abernathy Road where older two-stage systems get pushed hard through Georgia summers. Marco walks every homeowner through exactly what failed, why it failed, and what the written price will be before a single bolt turns. Tell me what it’s doing, and I’ll tell you what it costs in writing, before we start. That’s our approach on every Carrier call.

We’re an independent Carrier service provider, not an authorized Carrier dealer. That means we answer to you, not to a manufacturer’s quota. We carry the training, the diagnostic tools, and the OEM parts to do the job correctly, and we stand behind the work with The Garrison Standard: written price first, written guarantee on every repair, and a free return visit if the repair fails within the year.

Common Carrier HVAC Problems We Fix in Sandy Springs

• Infinity and Performance scroll compressor short-cycling or slugging. Carrier’s two-stage scroll compressor has an internal unloader that shifts between low and high stage. When that unloader sticks, the compressor can short-cycle or slug liquid refrigerant. We see it on Infinity 26 and Performance 17 units that run hard through Sandy Springs summers. The fix is usually electrical before it becomes mechanical, but catching it early matters.
• Infinity 98 secondary heat exchanger condensation and rust. The Infinity 98 furnace has a modulating inducer vane. When that vane doesn’t modulate correctly, combustion gases don’t move the way they should, and the secondary heat exchanger condenses and rusts. In Sandy Springs, where mild winters mean the furnace starts and stops often instead of running long cycles, this shows up more than you’d expect.
• Comfort 14 outdoor coil pinhole leaks from pollen and wet spring air. The Comfort 14 is a single-stage workhorse, but its outdoor coil sits exposed. In Sandy Springs, the spring pollen load is heavy, and wet, pollen-laden air sitting on the coil accelerates pitting. We find pinholes in Comfort 14 coils regularly, especially on units with tree-shaded lots that stay damp longer.
• Infinity communicating thermostat losing ECM indoor blower calibration after power flickers. The Infinity thermostat and ECM blower motor are paired. A thunderstorm rolls through Sandy Springs, the power flickers, and the thermostat loses calibration with the blower. The system still runs, but airflow is off, and you feel it. Recalibrating the pair takes a technician with the right Carrier software.
• Refrigerant undercharge from slow leaks at Schrader cores and coil joints. Carrier split systems, like every brand, lose refrigerant slowly through Schrader cores and brazed joints as the system ages. In a hot Sandy Springs summer, an undercharged system runs longer, cools less, and drives up your Georgia Power bill. We find and fix the leak before we recharge, so you’re not paying to refill a leaking tire.

Carrier Parts & Our Repair-vs-Replace Approach

Here’s how we handle parts on Carrier systems. If the failing part touches the communicating control loop, the ECM blower, or the heat exchanger, we default to genuine Carrier OEM parts. That’s the Infinity thermostat, the Infinity communicating board, the Infinity 98 inducer assembly, the heat exchanger. Those parts need to match Carrier’s specs exactly, or you create new problems.

If the failing part is a contactor, a capacitor, or a relay, that’s different. These are commodity components, and proven aftermarket brands often cost less without cutting lifespan. We’ll offer you the choice and show you the price difference in writing before we start.

When a compressor or heat exchanger fails on a Carrier unit over 12 years old, we quote both options: the AC Repair cost and a new 15 to 17 SEER replacement. You get real numbers for both paths, not a sales pitch. Most Sandy Springs homeowners decide based on the math, and that’s the way it should be.

Our Carrier Service Process – Step by Step

1. 1
   Diagnosis. We start with your Carrier system’s specific complaint. On Infinity units, we pull the communicating thermostat’s fault history first, then check the control loop. On Performance and Comfort units, we go through the standard sequence of operation. The written price for the diagnostic and the repair comes before any work starts.
2. 2
   Repair or install. We replace the failed Carrier part with OEM or a proven aftermarket option per our parts policy above. If you’re getting a new Carrier system, we size it with a Manual J load calculation, not a rule of thumb.
3. 3
   Test. After the repair, we run the system and verify performance. For AC calls, we check subcooling and superheat. For furnaces, we verify combustion analysis and temperature rise. We don’t leave until the numbers are right.
4. 4
   Warranty. Every repair carries a written guarantee for a full year under The Garrison Standard. If the repair fails in that time, we return at no charge. No fine print, no upgrade fee.
