What Are Some Common Misconceptions About Heat Pumps?
If you live in Greenville, SC area, you’ve probably heard a lot of opinions about heat pumps and how they work. Some swear by them. Others say, “They don’t work when it’s cold.” And then there’s always that one neighbor who says, “Stick with a traditional AC and furnace, it’s just better.”
But how much of that is fact and how much is just…a myth?
Let’s clear the air. Whether you’re thinking about replacing your old HVAC system or just trying to understand the difference, we’re here to bust the 5 common heat pump myths with local context and a little science that you will hopefully easily understand.
Myth #1: Heat Pumps Don’t Work in Cold Weather
The Truth: That used to be true 20 years ago, not anymore.
Heat pumps used to struggle when temperatures dropped below freezing. But today’s modern systems (especially the ones rated for cold climates) work efficiently down into the 20s and even teens, which is plenty for most Greenville winters.
We don’t usually get deep freezes here in the Upstate, and when we do, it doesn’t last long. Most high-efficiency systems installed today also come with a backup heat source (auxiliary or emergency heat) to keep you warm when the temps dip extra low.
Bottom line: Heat pumps do work in winter, especially in mild Southern climates like ours.
Myth #2: Heat Pumps Are Basically the Same as Air Conditioners
The Truth: They can cool your home like an air conditioner, but they also do one thing your AC unit can’t, heat your home too.
A central air conditioner only does one job: it removes heat from your home in the summer. A heat pump can do that and reverse the process in winter to bring heat in.
Think of it like a two-way street:
-
In summer, it pumps heat out of your house.
-
In winter, it pumps heat in from the outside air, even when it’s cold.
So if you’re comparing systems, remember this: a heat pump is more than an AC system. It’s a full heating and cooling solution that is much more energy-efficient.
Myth #3: Heat Pumps Cost More to Run Than Traditional Systems
The Truth: It depends on how your home is set up but in many Greenville homes, a heat pump is actually more efficient year-round.
Here’s why:
-
They move heat and they don’t generate it like a gas furnace does.
-
That makes them super energy-efficient in mild climates like ours.
-
In homes that don’t have access to natural gas, a heat pump can be far cheaper to run than an electric furnace.
Also, energy prices in South Carolina have been rising, especially natural gas. So more and more homeowners are switching to heat pumps to save money over time, especially when paired with smart thermostats or solar panels.
Myth #4: You Can’t Use a Heat Pump If You Already Have Ductwork
The Truth: They work with existing ductwork in most homes.
A lot of homeowners think they’d have to rip out their whole HVAC system to install a heat pump. Not true.
There are two main types of heat pumps:
-
Ducted heat pumps, which work just like your current system, using the same air vents and ductwork.
-
Ductless mini-splits, which are great for older homes, additions, or rooms that never seem to get comfortable.
If your home already has a central AC and furnace setup, you can often swap in a heat pump without replacing your ducts, especially if they’re in decent condition.
Myth #5: Heat Pumps Don’t Last as Long as Traditional Systems
The Truth: A well-maintained heat pump can last 15+ years, just like any other HVAC system.
Yes, it’s true that heat pumps run all year instead of seasonally like a separate AC and furnace. But modern units are designed for that and regular maintenance makes a huge difference.
In fact, in areas like Greenville where the winters are mild and we don’t get extreme cold or snow, they can actually outlast systems that go through the wear-and-tear of furnace heating cycles.
Pro Tip: Schedule maintenance twice a year. Once in spring, once in fall and keep your heat pump running smoothly year-round.
Should You Choose a Heat Pump or AC?
That depends on your home, your budget, and how you heat your home now.
Here’s a quick local cheat sheet:
| If you have… | Consider a… |
|---|---|
| All-electric home | Heat pump to save on winter bills |
| Gas furnace & central AC | Heat pump could still be more efficient, especially for cooling |
| Drafty home with old ducts | Ductless mini-split heat pump |
| High allergy concerns | Heat pumps offer better air filtration options |
