Heat Pump Replacement in Myrtle Beach, SC
When your heat pump starts struggling to maintain comfortable temperatures or your energy bills climb unexpectedly, it may be time to consider a replacement. At Conway Air Conditioning, we have been serving Horry County since the 1950s, making us one of the oldest heating and air conditioning businesses in Conway. Over those decades, we have replaced thousands of heat pump systems across Myrtle Beach, SC. Our experience gives us a deep understanding of the unique climate challenges that coastal South Carolina homeowners face, and we bring that expertise to every heat pump replacement project we take on.
Heat pumps are the dominant HVAC solution across the Lowcountry for good reason. They provide both heating and cooling from a single system, making them highly efficient in our moderate climate. The Department of Energy estimates that heat pumps can reduce electricity usage for heating by approximately fifty percent compared to electric resistance heating systems such as furnaces and baseboard heaters. In an area like Myrtle Beach where temperatures rarely drop below freezing for extended periods, heat pumps operate at peak efficiency for most of the year, delivering reliable comfort without excessive energy costs.
When to Replace Your Heat Pump
Most heat pumps have an expected lifespan of ten to fifteen years, though coastal environments with salt air exposure can sometimes reduce that timeline. If your system is approaching or has exceeded that age range, replacement becomes a practical consideration even if the unit still technically runs. Older systems lose efficiency gradually, meaning they consume more electricity to produce the same level of comfort. A system that operated at a sixteen SEER rating when new might function closer to ten or twelve SEER after a decade of wear, translating to significantly higher monthly utility costs that add up over time.
Beyond age, there are several performance indicators that signal the need for a heat pump replacement. Frequent repair calls are one of the most obvious signs. If you find yourself scheduling service visits multiple times per season, the cumulative repair costs may exceed the investment of a new system. Uneven temperatures throughout your home, excessive humidity that the system cannot manage, unusual cycling patterns where the unit turns on and off rapidly, and persistent strange noises from the outdoor or indoor unit all point toward a system that has reached the end of its useful life. Our NATE Certified Technicians can evaluate your current system and provide an honest assessment of whether repair or replacement makes the most financial sense for your situation.
Our Heat Pump Replacement Process
Replacing a heat pump is not as simple as swapping one unit for another. As a family owned and operated company, we take pride in a thorough, methodical approach that ensures your new system performs optimally for years to come. The process begins with a comprehensive load calculation, which measures your home’s specific heating and cooling requirements based on square footage, insulation levels, window placement, ductwork condition, and other structural factors. This calculation prevents the common industry mistake of installing an oversized or undersized system. An oversized heat pump short cycles, wasting energy and creating humidity problems. An undersized unit runs constantly without reaching desired temperatures.
Once we determine the proper system size, our team evaluates your existing ductwork and electrical infrastructure. Damaged or leaky ductwork can reduce system efficiency by as much as thirty percent according to Energy Star guidelines, so addressing these issues during replacement is critical. Our BPI (Building Performance Institute) certified professionals understand building science principles that directly affect how your heat pump interacts with your home’s overall envelope. We assess airflow, check for duct leaks, verify proper refrigerant line sizing, and ensure the electrical panel can support your new equipment. As a Factory Authorized Dealer, we install premium equipment backed by robust manufacturer warranties, giving you confidence in both the product and the installation quality.
Choosing the Right Heat Pump System
Modern heat pump technology has advanced dramatically, and today’s homeowners have more options than ever. Understanding the differences helps you make an informed decision that aligns with your comfort goals and budget. Here are the primary system types we install:
- Single-stage heat pumps operate at full capacity whenever they run, cycling on and off to maintain temperature, making them the most straightforward and budget-friendly option
- Two-stage heat pumps offer a low and high operating mode, allowing the system to run at reduced capacity during mild weather for improved efficiency and quieter operation
- Variable-speed heat pumps adjust their output continuously across a wide range, delivering the most precise temperature control, lowest energy consumption, and best humidity management available
- Ductless mini-split heat pumps provide targeted heating and cooling to individual rooms or zones without requiring ductwork, ideal for additions, sunrooms, or homes with aging duct systems
- Dual-fuel hybrid systems pair a heat pump with a gas furnace backup, automatically switching between fuel sources based on outdoor temperatures for maximum efficiency during rare cold snaps
SEER2 and HSPF2 ratings are the current industry standards for measuring cooling and heating efficiency respectively. As of January 2023, the federal minimum efficiency requirement for heat pumps in our region is fifteen SEER2 for cooling and 7.8 HSPF2 for heating. Higher-tier models can achieve twenty SEER2 or above, translating to meaningful long-term energy savings. Our team walks you through these specifications in plain language so you understand exactly what you are investing in.
Why Professional Installation Matters
Even the highest-rated heat pump will underperform if the installation is done incorrectly. Studies from the Department of Energy indicate that improper installation can reduce system efficiency by up to thirty percent. This includes issues like incorrect refrigerant charge, poor airflow configuration, improper thermostat placement, and inadequate sealing at connection points. Our team follows manufacturer specifications precisely on every installation, which is one of the reasons we have earned the President Award distinction. This recognition reflects a commitment to excellence that extends beyond technical skill to include customer communication, job site cleanliness, and thorough system commissioning.
After installation, we perform a complete system startup that includes verifying refrigerant charge, testing airflow across all supply and return registers, calibrating the thermostat, checking electrical connections, and running the system through both heating and cooling cycles. We walk you through your new system’s operation, explain filter maintenance schedules, and discuss any smart thermostat features that can further optimize your energy usage. As trusted HVAC services providers in Conway, SC and surrounding areas, we believe the relationship with our customers extends well beyond installation day. Proper ongoing maintenance keeps your new heat pump running at peak performance throughout its entire lifespan, protecting your investment and maintaining your home’s comfort year after year across every season Myrtle Beach experiences.
