This Orlando homeowner’s existing HVAC system was past its prime — undersized for the square footage, struggling to keep up with Central Florida humidity, and running up monthly energy bills that no longer made sense. Our team designed and installed a new dual-system Carrier setup that splits the home’s cooling load across two zones, dramatically improving both comfort and efficiency.
The Install
We started by pulling the existing equipment — outdoor condensers, indoor air handlers, refrigerant linesets, and the entire condensate drainage path. The new system includes:
- Two Carrier outdoor condenser units mounted on freshly poured concrete pads with rubber vibration isolators and hurricane-rated tie-downs
- A Carrier vertical air handler paired with a TopTech matching coil in the indoor mechanical closet
- A second matched air handler serving the secondary zone, with insulated supply trunk lines and a new return drop
- Complete replacement of all PVC condensate piping with proper P-traps, primary/secondary drain lines, and float-switch shutoffs above conditioned space
Why Two Systems
For larger Orlando homes — especially two-story floor plans or homes with significant additions — a single oversized system tends to short-cycle. The air leaves the registers cold but clammy, and the upstairs never quite catches up to the downstairs. Splitting the load between two right-sized Carrier systems means each one runs longer at lower capacity, pulling more humidity out of the air and drawing less power per cycle. The owner sees the difference on their next Duke Energy bill, and feels it inside the house every afternoon.
Built for Florida’s Climate
Every Orlando install our team handles gets a handful of non-negotiable details engineered for our climate:
- Condenser pads poured 4 inches above grade so they don’t sit in standing water during summer storms
- Hurricane-rated strap-down kits on each outdoor unit (we live in a wind zone, not a guideline)
- Fully insulated refrigerant linesets to minimize sweat, energy loss, and exterior corrosion
- Secondary drain pans under any air handler installed above living space, with float switches wired into the thermostat circuit
Carrier Premier Dealer
Bob Heinmiller is a Carrier Premier Dealer, the highest tier Carrier offers. That means our technicians are factory-trained on this exact equipment, and we can extend the manufacturer’s warranty terms past what a non-Premier installer is allowed to offer. This homeowner is covered for 10 years on parts and the compressor, registered automatically — no third-party paperwork to chase.
The Result
A quieter house, more even temperatures floor-to-floor, lower humidity readings on the thermostat, and a meaningful drop in monthly cooling costs. And — just as important — equipment installed cleanly enough that the next tech who opens that closet in 12 years will know exactly what they’re looking at.
