- Short Answer: The reversing valve and the defrost control are the two parts that go first, because they only work during heating season and a cooling-only system does not have them. Humidity and the age of the equipment explain most of the rest.
A reversing valve flips refrigerant flow so the machine heats instead of cools. A defrost board clears frost off the outdoor coil on damp mornings. Both sit idle through a long Lowcountry summer, then get asked to perform in January, which is why heat pump calls arrive in clusters during the first real cold stretch.
Goose Creek sits far enough off the open water that salt is less of a factor here than it is in Mount Pleasant or on the beach, and correspondingly the equipment tends to last closer to the upper end of its range. Humidity is the constant. Condensate systems work hard, and a drain line that has not been cleared in three years is a common and entirely preventable reason a system shuts itself down in July.
We test heating and cooling on every call rather than checking whichever mode the weather is asking for. It takes longer, and it is how a reversing valve going bad turns up in July rather than on the coldest night of the year. Our technicians would rather fix it right the first time than come back out in a cold snap.
Goose Creek homes run on heat pumps, and the money side of a replacement here works differently than it does a few miles south. Much of this area is served by Berkeley Electric Cooperative rather than Dominion Energy, which means the Dominion heat pump rebate that homeowners read about online does not apply, and a different set of co-op programs does. Repairs commonly run $200 to $700. A full replacement typically lands between $7,500 and $15,000 installed.
Those are market ranges, not a quote. Every home is measured and priced on its own.

Short Answer: A system replacement is permitted through the City of Goose Creek, and if your property is in a mapped flood zone the City applies flood requirements. Most of Goose Creek is inland, but low spots near the reservoir and creeks can flood.
Goose Creek is its own city, so a replacement is permitted and inspected through the City of Goose Creek, not Berkeley County or the City of Charleston. If your home is in a flood zone, we raise the outdoor unit above expected flood and handle the paperwork. Refrigerant work is done by technicians certified under EPA Section 608. Treating folks right for the long term is how we have lasted in the Lowcountry since 1947.
A few things to check before you call
- Set the thermostat to cool and check the batteries.
- Make sure the AC breaker has not tripped.
- Check the air filter. A clogged filter is a common, easy fix you can do yourself.
If those look fine and you are still warm, that is when to call us.

- Short Answer: Berkeley Electric Cooperative is a member-owned utility, not Dominion, and it runs its own incentive programs. The Dominion heat pump rebate does not apply to co-op members, so the first question on a Goose Creek replacement is whose name is on your power bill.
This matters more than it sounds. A homeowner reads about a $400 to $500 Dominion rebate, budgets around it, and then finds out at the end that their address is served by the cooperative. Service territories in South Carolina are set at the state level rather than by city limits, so the boundary does not follow anything you can see from the road.
What the cooperative offers instead is shaped differently. Rather than a straight rebate on a standard heat pump replacement, Berkeley Electric puts its money toward dual fuel conversions, smart thermostats, and low-rate financing for efficiency work, with a $500 rebate for members moving from a heat pump to a dual fuel system and a fixed five percent loan program that is repaid on the electric bill. Those are the co-op's terms and they change from time to time, so we confirm current program details before we put a number in front of you rather than repeating what a website said last year.
One more thing nobody can claim anywhere in South Carolina this year. The federal Section 25C credit was terminated for installations after December 31, 2025, and the state's HEAR and HOMES programs are funded but have not opened for applications.
Repair and replacement costs in Goose Creek
- Short Answer: Most heat pump repairs run $150 to $1,500 depending on the part. A replacement runs about $7,500 to $15,000 installed before any co-op incentive, plus the permit on the work.
These are 2026 market ranges for this region, not a Coastal Air Plus quote.
Equipment prices rose roughly 8 to 10 percent when the industry moved to the A2L refrigerants, and that is the market price now rather than a surcharge anyone should be adding to a bid. The defrost board and reversing valve rows never appear on an air conditioner estimate, because a cooling-only system does not have those parts. Where the co-op loan is not the right fit, we also offer financing options of our own.

Load management, thermostats, and how the co-op shapes your bill
- Short Answer: Berkeley Electric uses load management devices and a smart thermostat program to shift demand away from peak hours. Both interact with your heat pump, and neither is something a contractor should discover after installation.
The cooperative treats a load management device as a condition of participating in its incentive programs. In practice that means a switch the utility controls, and it is worth understanding what it does to your equipment before you agree to it rather than after.
The thermostat program works differently. The co-op syncs an enrolled thermostat and makes small automatic adjustments around peak periods, pre-cooling or pre-heating the house first so the change is less noticeable, with the option to opt out of a control period. If you are enrolled, the thermostat that comes with a new system needs to be compatible, which is a five-minute conversation at quoting time and a headache afterward.
Checking which utility serves an address before anyone starts talking about equipment is unglamorous work, and it is the kind that saves a homeowner a bad surprise. Creating Lasting Relationships has been this company's line since 1947, and out here a fair share of it is exactly that check. Where a house has rooms that never match the thermostat, zone control often does more for the bill than a larger system would.
Frequently Asked Heat Pump Repair Questions
If my house has two heat pumps, should I replace both at once?
- Not automatically. Two systems in one house are usually different ages, different sizes, and under different loads, and the upstairs unit almost always works harder than the downstairs one. Replacing both together can earn a better price on labor and gets the whole house on one refrigerant and one warranty date. Replacing one and keeping the other is perfectly reasonable if the second system has years left. We price it both ways so you can see the difference rather than being told.
Does a home warranty policy cover heat pump replacement?
- Sometimes, and usually less than people expect. Home warranty contracts often cap the payout well below the cost of a system, exclude anything they judge to be improper prior installation or lack of maintenance, and route you to whichever contractor they have a contract with. Read the cap and the exclusions before you count on it. If you have a claim in progress we will document what we find for the adjuster, but we do not decide what your policy pays.
After a power outage, does my heat pump need anything reset?
- Usually not, but give it time before you worry. Many systems have a built-in delay of several minutes before the compressor restarts, which protects it, so a unit that seems dead right after the power returns may simply be waiting. If it is still not running after fifteen minutes, check the breaker and the outdoor disconnect. If those are fine, call rather than cycling the breaker repeatedly, since that is hard on the compressor.
What efficiency should I buy if there is no rebate to chase?
- Buy for how the system runs, not for the number on the sticker. Without a rebate setting a floor, the honest comparison is what the equipment costs up front against what it costs to operate over ten or twelve years in a house that runs it nearly year round. In this climate the bigger comfort difference usually comes from how the equipment stages its output rather than from a point or two of rating, because longer runs at lower capacity handle humidity far better.
Does it matter that my air handler is in the attic?
- It matters for two reasons. An attic in a Lowcountry summer is brutally hot, so any leakage or missing insulation on the ductwork up there costs you more than the same defect would elsewhere in the house. And a condensate leak in an attic shows up on your ceiling rather than on a garage floor, which is why we look at the secondary drain pan and the float switch on every attic system we service. Where an attic system is failing a room addition, a ductless mini split is sometimes the cleaner fix.
Where we work in Goose Creek
We cover Goose Creek across the Red Bank and St. James corridors and out through the newer neighborhoods toward Carnes Crossroads. What we recommend shifts across that span, because a 1980s ranch and a house finished last year are carrying different equipment, different ductwork, and different expectations. Not better - just different is how we usually put it, and here the difference is mostly what is already in the wall.
Goose Creek sits in Berkeley County, and the full range of what we handle here is on our Goose Creek service page. For how heat pumps work and what the efficiency ratings mean, start with our heat pump repair and replacement guide. A system that heats and cools all year earns two visits a year, and that is what a VIP Maintenance Club plan is built around. We would rather treat them right for the long term than meet you for the first time on the worst day of the summer.
