    AC Replacement in Greer. Quick Answer

    Greer's rapid growth means thousands of homes need AC replacement at roughly the same time, as the systems installed during the construction boom of the 2000s and 2010s reach end-of-life. First Class Heating and Air provides professional AC replacement throughout Greer with proper sizing, quality installation, and transparent pricing that includes everything from equipment to permits to disposal.

    About Our AC Replacement Services in Greer

    Every Greer AC replacement begins with a Manual J load calculation specific to your home. We measure square footage, evaluate insulation, check window exposure and shading, inspect ductwork, and factor in Greer's specific climate conditions. This precise sizing prevents the common problems of oversized systems that short-cycle and underperform and undersized systems that struggle on the hottest days.

    For Greer homes built during the construction boom, we pay special attention to ductwork during replacement. Builder-grade ductwork installations sometimes include undersized trunk lines, excessive flex duct runs, and poorly sealed connections that reduce system performance by 20 to 30 percent. Addressing these issues during replacement ensures your new system delivers its full rated efficiency.

    The efficiency gains from AC replacement are dramatic for Greer homeowners with older systems. A 2008-vintage 13 SEER system has likely degraded to effective performance around 10 SEER today. Replacing it with a modern 16 SEER unit delivers approximately 37 percent lower cooling costs. For a typical Greer home, this represents $400 to $700 in annual energy savings.

    We offer flexible financing options to make AC replacement accessible for Greer homeowners. Many customers find that their monthly financing payment is partially or fully offset by the energy savings from their new high-efficiency system. Add any utility rebate the new system qualifies for, and upgrading to efficient AC equipment costs less than many Greer homeowners expect.

    I called First Class Heating and Air for a simple checkup on my system. Everything had been working fine so I didn’t necessarily have any concerns about the unit. Well, the technician found that there was a train missing from the unit and water was being released into my crawlspace! Granted the moisture levels were ok, but my goodness! What if that hadn’t been discovered? Anyway, they completed the tuneup, installed the drain etc all in under an hour and it was affordable. I recommend 11 times out of 10

    Local Pro Tip. Greer

    Greer homes near the Trade Street corridor and downtown area often have smaller lots with limited space for outdoor AC equipment. Modern AC condensers are available in more compact sizes than older models, and proper placement can satisfy both building code setback requirements and aesthetic considerations. We evaluate your site conditions during the free estimate to find the optimal location.

    AC Replacement FAQ. Greer, SC

    Answers to common questions about AC replacement in Greer.

    When should I replace my AC in Greer?

    Consider replacement when your system is over 12 years old, uses R-22 refrigerant, needs expensive repairs, cannot maintain comfortable temperatures, or when energy bills are climbing despite maintenance. Many Greer homes built between 2005 and 2012 are entering this replacement window now. A free assessment helps determine the best timing for your situation.

    What SEER rating should I choose for my Greer home?

    We recommend 16 SEER or higher for Greer homes based on the area's long cooling season. The federal minimum is 15 SEER for our region, but the incremental cost to step up to 16 SEER is modest and the energy savings over 15 years are significant. Variable-speed systems with 18 to 20 SEER ratings offer the best comfort and efficiency for homeowners willing to invest more upfront.

    How long does AC installation take in Greer?

    Most standard Greer AC replacements are completed in one day. We typically arrive in the morning, remove the old system, install new equipment, test and commission the system, and have you cooling by afternoon. Installations requiring ductwork modifications or electrical panel upgrades may require a second day.

    Do you handle permits for AC replacement in Greer?

    Yes, we manage the entire permitting process for Greer AC replacements. This includes pulling the necessary mechanical and electrical permits and scheduling required inspections. You do not need to visit any government offices or coordinate with inspectors yourself.

    Can you replace a window unit with central AC in Greer?

    Yes, we install central AC systems in Greer homes that currently rely on window units. Options include traditional ducted systems and ductless mini-splits. Mini-splits are especially popular for older Greer homes where installing ductwork would be impractical or prohibitively expensive. Both options provide dramatically better cooling and efficiency than window units.

    • Installed a new Rheem dual fuel system, off Royal Troon Court, Greer, SC. This job was a full dual fuel system replacement: a Rheem 16 SEER2 variable-speed heat pump paired with a Rheem 80% AFUE gas furnace and variable-speed ECM blower. The system switches between electric and gas heat on its own depending on outdoor temperature, which keeps comfort steady and costs down. We ran new electrical connections, updated the flue venting, gas piping, and drain configuration as needed, and checked the refrigerant line set before charging. Finished with a full startup and performance test, plus a Wi-Fi thermostat and whole-home media filtration for better air quality.
    • Replaced a failed zone damper actuator, off Rockbrook Court, Greer, SC. This was a zoning call. We checked voltage right at the actuator terminals rather than just the wire, then verified the control signal was switching correctly between open and close commands. With good voltage and signal but no movement or motor sound, that pointed to a failed actuator rather than a wiring issue. We also confirmed the damper blade itself wasn't binding. The old actuator was pulled and a new one installed, and the damper is now opening and closing properly with the thermostat calls.
    • Replaced a failed emergency drain pan and rerouted drain line, off Sandpine Way, Greer, SC. The emergency drain pan under this air handler had failed, so we shut the system down, disconnected the drain lines, and lifted the unit off to pull the old pan. We set a new pan sized to the unit, leveled it, and reset the air handler so condensate drains properly. We reconnected the primary drain, tested the float switch on the new pan, ran the system, and checked every joint for leaks before confirming both drains were flowing.
    • Checked out an aging R-22 heat pump in Greer, off De Kalb Drive, Greer, SC. Found this heat pump still running but a bit low on refrigerant. Since it's an older R-22 system, topping off the charge isn't a real fix, that refrigerant is being phased out and increasingly hard to source, so it's really just a band-aid on a system nearing the end of its service life. We talked through options on site, and the homeowner is looking at replacing the split system with a new packaged heat pump, which would also mean updating the ductwork to match. We're putting together a proposal for the full changeover.
    • Fixed a refrigerant leak on a mini-split, off South Old Highway 14, Greer, SC. This ductless system had a flare joint that had worked loose, letting refrigerant escape and leaving the indoor unit blowing warm. We tracked the leak to the fitting, repaired the flare connection, and pulled the system back down to check it held. After recharging and testing, the mini-split was back to blowing cold air and running the way it should.
