Heat pump replacement cost in North Myrtle Beach usually lands between 5,500 and 12,000 dollars installed, according to the 2026 Angi and Forbes Home cost guides. If your system is on its way out, that range probably raises more questions than it answers. This guide walks through what the number covers, what moves it on the coast, and how to pay for it.
One thing up front. We cannot quote your exact system from a blog post, and we will not pretend the price comes down to square footage. Heat pumps are the standard setup on the Grand Strand, and the right price for yours starts with a load calculation. That is where we begin every replacement.
Quick answer
What does heat pump replacement cost on the Grand Strand?
In North Myrtle Beach, replacing a heat pump usually costs about $5,500 to $12,000 installed, based on the 2026 Angi and Forbes Home cost guides. The exact price comes from a Manual J load calculation on your home, not its square footage, and Comfort Masters puts every quote in writing after measuring.
Key things to know about heat pump replacement cost
If you read nothing else, these five points cover what actually sets the price of a new heat pump on the Grand Strand.
- Size is set by math, not a rule of thumb. A Manual J load calculation measures what your home needs. An oversized heat pump costs more and controls humidity worse.
- The coast adds cost for a reason. Salt air corrodes outdoor equipment faster here, so coastal-rated units with coated coils are worth paying for.
- Efficiency is a trade. Higher SEER2 and HSPF2 ratings cost more up front and use less energy every month the system runs.
- The federal tax credit is over. The 25C credit ended for systems placed in service after December 31, 2025, per the IRS. Financing is still available.
- One system does two jobs. A heat pump cools in summer and heats in winter, which is why it is the most common setup on the coast.
What a new heat pump costs in North Myrtle Beach
A full heat pump replacement typically costs about 5,500 to 12,000 dollars installed, according to the Angi and Forbes Home cost guides for 2026. Angi puts the national average near 6,100 dollars. Coastal homes often land toward the upper end of the range, because equipment that stands up to salt air costs a little more.
Treat those numbers as the field, not the final score. The same three-ton heat pump can be priced very differently depending on the ductwork it connects to and the equipment grade the coast calls for. The card below shows the two most common configurations side by side.

Cost by system configuration
Most heat pump replacements on the Grand Strand fall into three configurations. The right one depends on your home, your existing equipment, and what the load calculation shows.
Split-system heat pump
A split system pairs an outdoor unit with an indoor air handler and coil. It is the standard replacement here, because one system covers cooling and heating. When the existing ductwork is in good shape, a split-system swap usually lands in the lower to middle part of the installed range above.
Packaged heat pump
A packaged heat pump puts every component in one cabinet, usually on a slab or a flat roof. It is common on beach homes and slab-foundation houses that have no attic or crawl space for an indoor unit. Pricing tracks the same installed range, with placement and tie-in determining where it lands.
Dual-fuel system
A dual-fuel setup pairs a heat pump with a gas furnace that takes over on the coldest nights. It costs more than a heat pump alone, because you are buying and venting two pieces of heating equipment. Grand Strand winters are mild enough that most homes here do not need it, and a load calculation settles the question.
Cost by efficiency and size
Two technical choices shape the final number more than almost anything else. Both are worth understanding before you compare quotes.
Efficiency ratings (SEER2 and HSPF2)
SEER2 measures how efficiently a heat pump cools, and HSPF2 measures how efficiently it heats. New split-system heat pumps must meet at least 14.3 SEER2 and 7.5 HSPF2 under U.S. Department of Energy standards, and you can buy higher. A higher-efficiency unit costs more up front and lowers what you spend on power across a long coastal cooling season.
System size (tonnage)
Size is measured in tons of capacity, and it should come from a load calculation, not from the size of your old unit or your home's square footage. An oversized heat pump short-cycles. It conditions the air fast, shuts off, and leaves humidity behind, so the house feels clammy even at the right temperature. A right-sized system runs longer, steadier cycles that control both temperature and moisture.
What drives your heat pump price in coastal SC
Three factors drive most of the gap between a low quote and a high one: the system size your home actually needs, the condition of your ductwork, and the equipment grade salt air demands. Backup heat and staging choices move the number too. Here is how each one works.
Why the coast is hard on equipment
How salt air wears a heat pump down.
Salt in the air
Airborne salt drifts inland and settles on the outdoor unit year-round.
Coil corrodes
Salt eats at the coil fins and cabinet faster than inland air ever would.
Efficiency drops
A corroded coil cannot move heat well, so the system runs longer and harder in both seasons.
Shorter lifespan
Constant strain wears the unit out years before its 15-year average.
The fix is straightforward: coastal-rated equipment with coated coils slows corrosion, and rinsing the outdoor coil with fresh water on a schedule clears the salt before it sets.
Sizing and design (Manual J, S, and D)
The real heat pump price comes from a load calculation, not your home's square footage. We use ACCA Manual J to measure the load, Manual S to select equipment that matches it, and Manual D where ductwork needs design. You get the findings in writing, which is what our line means: engineered, not estimated. Our coastal Carolina HVAC guide goes deeper on why sizing matters here.
Ductwork condition and design
Ductwork is the other half of the system. Leaky or undersized ducts waste the capacity you paid for, and humid crawl spaces on the coast are hard on duct insulation and sealing. A replacement sometimes includes duct repair or a redesign, and finding that out before the install is far cheaper than finding out after.
Backup heat strips, staging, and permits
Heat strips are electric elements in the air handler that back up the heat pump during cold snaps, and most systems here include them. Compressor staging matters too. A two-stage or variable-speed unit costs more than a single-stage one and controls humidity better across our long summers. Permits and code requirements in Horry County and Brunswick County round out the price. None of these are upsells. They are the difference between a system that holds up and one that does not.
Ways to pay for a heat pump replacement
Financing through Synchrony
A new system does not have to be paid all at once. Comfort Masters offers financing through Synchrony, and you can review the current terms on our HVAC financing options page. We do not publish rates here, because the terms come from the lender.
What happened to the federal heat pump tax credit
The federal 25C credit, which covered up to 2,000 dollars of a qualifying heat pump installation, ended for systems placed in service after December 31, 2025, according to the IRS. A standard 2026 installation no longer qualifies, no matter when the equipment was purchased. If your system went in during 2025, keep the documentation and talk with a tax professional about claiming it on this year's return.
In-house savings: maintenance plans
Once the new system is in, a maintenance plan protects it. Our one-visit agreement is 115 dollars a year and covers an annual inspection, a cleaning, and priority scheduling. The two-visit plan is 175 dollars a year, adds a spring coil clean and a fall service, and includes a 10 percent discount on repairs. You can compare both on our HVAC maintenance plans page.
What is included when we replace your heat pump
A replacement quote from Comfort Masters covers the work, not just the box. Here is what that looks like from first visit to finished install.
Before the install: measure and design
We run the Manual J load calculation, select equipment to match it, and design the ducts where needed. You get the findings in writing, with photos, so the quote explains itself. If the numbers say your current system still has life in it, we tell you that too.
Installation day and after
We recover the old refrigerant per EPA 608 rules, remove the old system, set and commission the new one, and pull the permits the job requires. Every new installation carries a three-year labor warranty. If you are weighing a full swap, our new system installs in North Myrtle Beach page walks through the process in more detail.
Should you repair or replace your heat pump?
Replacement is not always the answer, and we will tell you when it is not. We diagnose before we recommend, and our technicians do not work on commission. One screening test we use: multiply the system's age by the repair quote in front of you. If the result tops 5,000, replacement deserves a serious look.
When a repair is the right call
If the system is under about ten years old, the failure is a single component, and the rest of the unit is sound, a repair usually makes more sense than a replacement. A clear written diagnosis is the way to know.
When replacement makes sense
Age, repeat breakdowns, and rising power bills all point toward replacing rather than repairing again. So does refrigerant. Older systems run R-410A, which the EPA is phasing down under the AIM Act, while new equipment ships with A2L refrigerants such as R-454B or R-32. Either way, the right next step is a professional evaluation, not a guess. If your home loses cooling during a heat wave and anyone shows signs of heat illness, call 911 first, then call us.
Why heat pumps fit North Myrtle Beach homes
Mild winters, humid summers
Coastal South Carolina sits in a hot-humid climate zone where summer design temperatures reach the mid 90s and winters stay mostly mild. That is the exact weather a heat pump is built for. Cold snaps still arrive in January, and that is what backup heat strips are there to cover.
One system instead of two
A heat pump heats and cools from the same outdoor unit, so there is one system to buy, one to maintain, and one to replace. That is why it is the most common setup we see on the Grand Strand. From summer coil rinses to winter heating calls, our heating services in North Myrtle Beach cover both halves of the job.
Common questions
Heat pump replacement cost, answered.
How much does heat pump replacement cost in North Myrtle Beach?
A full heat pump replacement usually runs about 5,500 to 12,000 dollars installed, according to the 2026 Angi and Forbes Home cost guides. Coastal homes often land toward the upper end, and the exact price comes from a Manual J load calculation on your home, not a rule of thumb.
How much does a heat pump cost for a 2,000 square foot house?
Square footage alone cannot price a system. Two 2,000 square foot homes can need different heat pumps depending on insulation, windows, and ductwork. A Manual J load calculation measures what your home actually needs, which is why we measure before we quote. National guides still put most installs between 5,500 and 12,000 dollars.
What is the 5,000 rule for heat pump repair versus replacement?
Multiply the age of the system by the cost of the repair in front of you. If the result tops 5,000, replacement usually deserves a serious look. It is a screening tool, not a verdict, so we confirm it with a written diagnosis before recommending either path.
How long do heat pumps last near the beach?
A well-maintained heat pump lasts about 15 years on average, per the U.S. Department of Energy. Salt air and near-year-round runtime shorten that on the Grand Strand. Coastal-rated equipment, regular coil rinses, and a maintenance plan help a system reach its full span here.
Should I replace a heat pump that is more than 10 years old?
Not automatically. If the failure is a single component and the rest of the system is sound, a repair can still make sense at 10 years. Age, repeat breakdowns, and older R-410A refrigerant push toward replacement. A written diagnosis tells you which side your system is on.
Is there a heat pump tax credit in 2026?
No. The federal 25C credit, which covered qualifying heat pumps, ended for systems placed in service after December 31, 2025, according to the IRS. A standard 2026 installation does not qualify. Talk with a tax professional about your situation, and ask us about financing through Synchrony.
Do you offer financing for a new heat pump?
Yes. Comfort Masters offers financing through Synchrony, and current terms are on our financing page. We do not publish rates here because the terms come from the lender. Financing is worth weighing now that the federal tax credit has ended.
What do SEER2 and HSPF2 mean on a heat pump?
SEER2 measures cooling efficiency and HSPF2 measures heating efficiency. New split-system heat pumps must meet at least 14.3 SEER2 and 7.5 HSPF2 under U.S. Department of Energy standards. Higher numbers cost more up front and use less energy every month the system runs.
Does a higher SEER2 heat pump lower my electric bill?
In most cases, yes. A higher SEER2 unit uses less electricity for the same cooling, per the U.S. Department of Energy, and Grand Strand cooling seasons are long. Actual savings depend on your usage, your ductwork, and your utility rate, so we walk through the math during the quote.
Why do coastal heat pumps need salt-air protection?
Airborne salt settles on the outdoor coil and eats at the fins and cabinet faster than inland air would. Coastal-rated equipment with coated coils slows that corrosion, and rinsing the coil with fresh water on a schedule clears the salt before it sets.
What are backup heat strips and do I need them?
Heat strips are electric elements inside the air handler that back up the heat pump during cold snaps. Most Grand Strand systems include them, and they are sized during system design. Right-sized strips keep the house warm in January without inflating every winter power bill.
What does your service call cost, and what do I get for it?
A diagnostic service call is 55 dollars in Little River and Calabash, and 95 dollars elsewhere on the Grand Strand. It covers a full diagnosis with written findings before any repair is quoted. For a planned replacement, call us and we will explain how the quote works.
What is included in a Comfort Masters heat pump replacement?
A Manual J load calculation, equipment selected to match it, duct design where needed, permits, removal of the old system, and commissioning of the new one. You get the findings in writing with photos, and every new installation carries a three-year labor warranty.
How long does a heat pump replacement take to install?
Most residential heat pump replacements are completed in one day once the equipment is on site. A job that adds ductwork repair or redesign takes longer. We confirm the timeline in the written quote, so you know what to expect before the work begins.
