Greenville’s housing market is booming, and many homeowners are upgrading aging HVAC systems to keep up with modern comfort expectations and energy efficiency standards. Whether you’re in a historic home near downtown, a 1990s build in Five Forks, or a newer development in Simpsonville, the installation process matters as much as the equipment you choose.
Our installation crews — including Lukas, Paris, and Bailee — handle HVAC replacements across Greenville County every week. Here’s what a professional installation looks like.
Step 1: The In-Home Assessment
Before we quote a price or recommend equipment, a comfort advisor visits your home and performs a Manual J load calculation. This accounts for:
- Square footage and ceiling height
- Insulation levels (walls, attic, crawlspace)
- Window count, size, and orientation
- Number of occupants
- Ductwork condition and sizing
- Current system performance issues
Greenville homes vary significantly — a 1960s brick ranch in Taylors has very different needs than a 2015 two-story in Simpsonville. A proper load calculation ensures the system is sized correctly. Oversized systems short-cycle and underperform on humidity. Undersized systems run constantly and can’t keep up on the hottest days.
Step 2: System Selection
Based on the load calculation, we present options at multiple price points:
Good: Standard efficiency system (14-15 SEER2) — reliable, affordable, meets current code requirements.
Better: Mid-efficiency system (16-17 SEER2) — lower operating costs, often qualifies for utility rebates.
Best: High-efficiency variable-speed system (18-20+ SEER2) — lowest operating costs, best humidity control, quietest operation. Heat pump versions qualify for federal tax credits up to $2,000.
We carry multiple brands so the recommendation is based on your home’s needs, not a manufacturer quota.
Step 3: Installation Day
A typical system replacement takes one day for a straight swap. Our crews arrive early, protect your home’s floors and walls, and follow a systematic process:
Removal: The old indoor and outdoor equipment is disconnected, removed, and loaded for proper disposal. We handle everything — you don’t need to arrange separate pickup.
Indoor unit installation: The new air handler or furnace is set in place, connected to the ductwork, and wired. If transitioning from a furnace to a heat pump air handler (or vice versa), additional modifications may be needed.
Outdoor unit installation: The new condenser is placed on a level pad, refrigerant lines are connected (brazed, not just tightened), and electrical connections are made.
Refrigerant charge: The system is evacuated with a vacuum pump (to remove moisture and contaminants), then charged with the precise amount of refrigerant specified by the manufacturer. This step is critical — overcharging or undercharging directly affects efficiency and equipment life.
Thermostat: A new thermostat is installed and programmed (or your existing smart thermostat is reconnected and configured).
Step 4: Startup and Testing
This is where many installers cut corners. Our crews don’t:
- Temperature split test: Measure supply and return air temperatures to verify 15-20°F differential in cooling mode.
- Airflow verification: Measure static pressure to confirm proper airflow across the coil.
- Electrical readings: Record voltage, amperage, and capacitor readings for baseline documentation.
- Drain test: Verify condensate drainage is flowing properly.
- Homeowner walkthrough: We show you how to operate the thermostat, where the filter is, and what maintenance you should do.
Greenville-Specific Considerations
Humidity: Greenville’s humidity is significant from May through September. A properly sized system with good dehumidification capability makes a noticeable difference in comfort. Variable-speed systems excel here because they run longer at lower speeds, removing more moisture.
Pollen: Greenville consistently ranks among the highest pollen cities in the US. If indoor air quality is a concern, we recommend pairing your new system with a high-MERV filter and UV-C germicidal light.
Ductwork: If your existing ducts are original to a home built before 1990, consider duct sealing or replacement alongside the new system. New equipment pushing air through leaky ducts is like buying a sports car and driving it on flat tires.
