Here in Central Florida, the heat pump versus gas furnace choice isn’t as close as most homeowners expect. Our winters stay short, our cooling season runs most of the year, and plenty of Lake County homes don’t have a gas line at all. That doesn’t make it a silly question — it’s one worth answering honestly, with real numbers and no sales pressure. We’ve walked dozens of Mount Dora and Clermont homeowners through this exact decision, so let’s compare the two systems the way we’d explain it on your own front porch.
TL;DR Quick Answers
Heat Pump Vs Gas Furnace
A heat pump moves heat instead of burning fuel, and it cools your home in summer too. A gas furnace burns natural gas or propane to make heat, and it needs a separate air conditioner for the warm months.
Choose a heat pump if you live in a mild or warm climate, you want one system for both heating and cooling, or you’d like better humidity control. That describes nearly every home in Central Florida.
Choose a gas furnace if your winters stay below freezing for weeks at a time and natural gas costs far less than electricity where you live.
The Central Florida bottom line: for homes in Mount Dora, Clermont, and DeLand, a heat pump is almost always the better fit. Many local homes don’t even have a gas line, so the real question is usually which heat pump, not which fuel.
Top Takeaways
- A heat pump wins on efficiency in a mild climate. It moves heat rather than making it, so it delivers more warmth per dollar than any furnace when temperatures stay moderate.
- A gas furnace usually costs less to install, but it only heats. You’d still need a separate air conditioner, and in Central Florida you run cooling far more than heat.
- One heat pump handles both heating and cooling. For most Florida homes replacing an aging system, that’s one purchase instead of two.
- Humidity matters as much as temperature here. A heat pump controls moisture better than a furnace paired with a separate air conditioner, and in our climate you feel that difference every day.
- Your utility rates decide the operating-cost math. Look up your electricity rate, and your gas rate if you have one, before you compare anything else.
- The incentive picture changed this year. The federal tax credit for air-source heat pumps ended on December 31, 2025, so today the savings come from Florida utility and state programs instead.
- On the pros and cons: a heat pump gives you efficiency, cooling, and humidity control. A gas furnace gives you fast, intense heat and a lower install price, which counts most in genuinely cold climates.

How Each System Heats Your Home
A gas furnace burns natural gas or propane inside a heat exchanger. A blower pushes the warmed air through your ducts. It’s direct and fast, and it produces strong, hot air.
A heat pump doesn’t burn anything. It uses electricity to move heat from one place to another. In winter, it pulls warmth from the outdoor air and carries it inside. In summer, it runs in reverse and works as your air conditioner. If you want the technical side, here is a clear explanation of how a heat pump works.
That one difference, making heat versus moving heat, shapes the rest of the comparison. It drives the efficiency numbers, the monthly bill, and the way each system feels once it runs in your home.
Efficiency: AFUE vs. COP
The two systems use different efficiency scales, which makes a head-to-head number tricky.
AFUE measures a gas furnace. It stands for Annual Fuel Utilization Efficiency, and a 96% AFUE furnace turns 96 cents of every fuel dollar into heat. That’s strong, and it can’t go above 100%.
COP measures a heat pump’s heating efficiency, while SEER2 and HSPF2 track its seasonal cooling and heating performance. Because a heat pump moves heat instead of creating it, it can deliver two to three units of heat for every unit of electricity it uses. In mild weather, that puts it well ahead of any furnace.
Here is the honest catch. A heat pump loses efficiency as the outdoor air turns very cold. In Central Florida, that rarely happens. Our winters stay mild enough that a heat pump runs in its efficient range almost all season, which is exactly why heat pump heating suits warm climates so well.
Cost: Upfront and Monthly
Upfront, a gas furnace often costs less to install than a heat pump. But that lower price buys you heat and nothing else. You’d still need an air conditioner, while a heat pump covers both jobs in one unit.
Operating cost comes down to your local rates. A heat pump runs on electricity. A furnace runs on gas. Whichever costs less where you live, and by how much, decides your monthly bill. For a wider national breakdown, this cost-and-efficiency comparison is a useful reference.
For Central Florida specifically, we walk through real numbers in our heat pump installation cost guide. The short version: in a Zone 2 home that already runs air conditioning most of the year, a heat pump usually wins on total cost. You buy one system instead of two, and you run it efficiently.
Comfort and Humidity
Most national comparisons stop at temperature. In Florida, that leaves out half the story.
A gas furnace delivers heat in short, hot bursts. The air warms up quickly, and it also feels dry. A heat pump moves a gentler, steadier stream of air. Plenty of homeowners prefer that even warmth, though a few miss the strong blast of a furnace.
The bigger issue is moisture. A heat pump controls humidity better than a furnace paired with a separate air conditioner. The U.S. Department of Energy notes that high-efficiency heat pumps dehumidify better than standard central air conditioners. We’ve serviced hundreds of homes across Lake County, and humidity is what people actually notice day to day, far more than a couple of degrees on the thermostat.
Lifespan and Maintenance
Both systems last a long time when you take care of them. A heat pump usually runs about 15 to 20 years, and a quality gas furnace can last longer, since it works only in the heating season. A heat pump runs in both seasons, so it earns regular maintenance.
Either way, the single best habit is a clean filter. A clogged filter strains the system, raises your bill, and shortens equipment life. Our furnace filter MERV rating guide explains which rating fits your home. If you go with a heat pump, our heat pump maintenance guide covers the seasonal checkups that keep it near its rated efficiency. You’ll find more in our heat pump resource library.
The Honest Florida Reality
Central Florida sits in Climate Zone 2. Our winters are short and mild, our cooling season is long, and that combination strongly favors a heat pump, which handles both jobs in one system.
Here is a point national guides miss. Many Central Florida homes have no natural gas line at all. In those homes, the “furnace” is usually electric strip heat built into the air handler, not a gas furnace. So the real local decision is often a heat pump versus electric strip backup, not a heat pump versus gas.
We tell every homeowner the same thing: look at the envelope before the equipment. Sealing ductwork, adding insulation, and closing air leaks often improve comfort more than a fuel switch ever could. We’ve fixed more Mount Dora homes with sealed ducts than with a new heating system.
“After more than a decade servicing systems across Lake County, we’ll say it plainly: in our short Zone 2 winters, a heat pump handles heating and cooling in one unit and controls humidity in a way a gas furnace simply can’t. We’ve solved more Mount Dora and Clermont comfort problems by sealing ductwork than by changing the fuel a home burns.”

Statistics
Three numbers worth keeping in mind, each one straight from a federal agency.
Up to 75% Less Electricity for Heating
The U.S. Department of Energy reports that today’s heat pumps can cut electricity use for heating by up to 75% compared with electric resistance heating, such as baseboard heaters. Source: U.S. Department of Energy, Heat Pump Systems.
52% of Home Energy Goes to Heating and Cooling
The U.S. Energy Information Administration found that in 2020, space heating and air conditioning together made up 52% of the average household’s annual energy use. The system you pick shapes about half your energy bill. Source: U.S. Energy Information Administration, Use of Energy in Homes.
28% of Florida Home Energy Goes to Air Conditioning
EIA data shows air conditioning accounted for 28% of total home energy use in Florida, against just 2% in Maine. That long cooling season is a big reason a heat pump, which cools as well as heats, fits Central Florida so well. Source: U.S. Energy Information Administration, 2020 RECS.
Final Thoughts and Opinion
After years of service calls across Lake County, our opinion is settled. For nearly every home in Mount Dora, Clermont, and DeLand, a heat pump is the better choice. It heats, it cools, it controls humidity, and it runs efficiently through our mild Zone 2 winters.
A gas furnace still earns its place in the right setting. If your winters are long and harsh and natural gas runs inexpensive, a furnace makes sense. That is not Central Florida.
We’ll repeat the point we make on every service call: look at your home before you look at equipment. Sealed ducts, solid insulation, and a clean filter often deliver more comfort than any fuel switch. The best system in a leaky house still struggles.
If you do replace your system, get a few estimates and ask each contractor for a Manual J load calculation. That’s how a system gets sized to your actual home instead of a rough guess. The right size, installed well, matters more than the brand on the box.
Frequently Asked Questions
Q: Does a heat pump cost less to run than a gas furnace?
A: In a mild climate like Central Florida’s, usually yes. A heat pump moves heat instead of burning fuel, so it delivers more warmth per dollar when temperatures stay moderate. Your local electricity and gas rates set the exact gap, so check both before you compare.
Q: Should I replace my furnace with a heat pump?
A: In Central Florida, it’s well worth considering. A heat pump replaces both your furnace and your air conditioner with one system, and it suits our Zone 2 climate. If your furnace is aging and your air conditioner is too, switching to a heat pump usually makes the most sense.
Q: Do heat pumps work well in Florida’s climate?
A: Yes. Heat pumps perform best in mild and warm climates, and Central Florida fits that profile closely. Our winters rarely turn cold enough to push a heat pump out of its efficient range, and the same unit carries our long cooling season.
Q: How long do a heat pump and a gas furnace last?
A: A heat pump usually lasts about 15 to 20 years, and a quality gas furnace can last longer, since it runs in only one season. Regular maintenance and clean filters extend the life of either one.
Q: What is the difference between AFUE and COP?
A: AFUE measures how much of a furnace’s fuel becomes heat, shown as a percentage. COP measures how many units of heat a heat pump delivers per unit of electricity. They’re different scales, which is why you can’t compare heat pump and furnace efficiency with a single number.
Q: Does my Central Florida home even have a gas furnace?
A: Many don’t. A large share of local homes have no natural gas line, and their heat comes from electric strip heat inside the air handler. If you’re not sure, a quick look at your equipment, or a call to us, will tell you what you have.
Q: Are there still incentives for installing a heat pump?
A: The federal tax credit for air-source heat pumps ended on December 31, 2025. Today, the savings come mainly from Florida utility and state programs, and those change over time. Check the ENERGY STAR Rebate Finder for current offers in your ZIP code before you buy.
