🤔Thinking about a gas furnace and air conditioner system? Whether you're upgrading your home HVAC or looking for furnace and AC deals that won't break the bank, Tony the Trusted Tech lays out everything you need to know about gas-powered air conditioning, propane furnace combos, and why systems like the Goodman 2.5 Ton 14.5 SEER2 AC and Air Handler are changing the game.
Gas AC Systems 101 – What You’re Really Getting Into
Let’s cut through the fluff. When folks talk about a gas AC system, they’re usually referring to a gas furnace with an electric-powered air conditioner. True gas-powered air conditioners—the kind that run cooling cycles off natural gas or propane—do exist, but they’re rare and mostly used in off-grid or commercial settings.
For the average homeowner, a natural gas furnace with a central AC unit is the most common combo. The heating comes from the gas furnace, and the cooling from an electric AC compressor. That’s what we call a forced air furnace with cooling unit setup. Reliable. Efficient. Familiar.
Here’s the Catch
The market is changing. New refrigerants like R-32 are pushing efficiency higher, and incentives are out there for upgrading your system. So before you go all-in on a gas AC setup, let’s talk shop.
Meet Your New Benchmark: Goodman 2.5 Ton 14.5 SEER2 AC System
Let me show you something solid. The Goodman 2.5 Ton 14.5 SEER2 AC and Air Handler System is a fantastic base for a furnace and AC combo special. Here's why:
- 2.5 Ton Cooling Capacity – Ideal for 1200–1500 sq. ft. homes
- 14.5 SEER2 Rating – Energy-efficient and meets new 2023 DOE standards
- R-32 Refrigerant – Lower Global Warming Potential than R-410A
- Compatible with Gas Furnaces – Easily paired with a natural gas furnace or propane furnace
If you’ve got a gas line or propane tank, this is the kind of system you want. It delivers cost-effective cooling while giving you options for efficient heating with a gas furnace and air conditioner system.
What Is the Outside AC Unit Called in a Gas System?
Good question. Whether you call it the ac outside unit, ac external unit, or just “that big thing next to the house,” it’s the condenser. In gas HVAC setups, this condenser is electric—it works in tandem with your furnace and central air setup. It's not gas-powered. The gas part is for heat, not cool.
If you’re searching for gas powered air conditioning units or gas air con because you think your AC needs to run on natural gas, you’re probably better off sticking with a hybrid system like the Goodman one we just talked about. It’s more efficient and a lot easier to maintain.
Should You Get a Propane Furnace with Air Conditioning?
If you’re in a rural area or off the natural gas grid, propane furnace and AC units are a great option. Here’s what I like:
- High heat output even in freezing weather
- Clean burning and low emissions
- Easy tank refills in remote areas
A propane furnace with air conditioning setup can be just as efficient as natural gas these days. Just make sure you get your sizing right, especially on the cooling end.
Pair a 2.5 ton unit like the Goodman above with a propane-compatible furnace, and you’ve got a furnace and AC package that can handle both summer scorchers and January blizzards.
What About Gas Air Conditioning Systems?
Okay, now we’re getting into niche territory. Actual gas air conditioners (powered by natural gas or even gasoline) used to be popular decades ago. But in today’s world, they’re:
- Expensive
- Hard to find
- Not as efficient as electric cooling
Most homeowners looking for gas air conditioning systems really just need a high-performance electric AC paired with a gas furnace. That’s why systems like the Goodman 2.5 Ton are smart—you're still getting top-tier efficiency while leveraging gas heat in the winter.
Still curious? You can check out specialized systems at Energy.gov, but odds are you’re better off sticking with what works.
Tony’s Top Furnace and AC Deals for 2025
Let’s get into the real-world deals. If you’re looking to upgrade or replace your current system, here’s what I’d recommend:
🔧 Best Furnace and AC Package (Gas):
Goodman 2.5 Ton 14.5 SEER2 AC + 80% AFUE Gas Furnace Combo

These systems fall under the category of natural gas AC systems, meaning they give you electric cooling plus natural gas-powered air conditioning support through the furnace.
Key Terms: Let’s Break ‘Em Down
Let’s demystify a few of the keywords homeowners throw around:
- Gas AC Unit – Usually refers to the full combo (electric AC + gas furnace)
- Natural Gas AC – Same as above; natural gas fuels the heating side
- Gas Furnace with AC – A classic combo for decades
- Gas Powered AC Unit – Rare, but technically possible (mostly off-grid or commercial)
- Propane Furnace and Air Conditioner – Ideal for homes without gas lines
Most of what you're seeing in online searches for gas air conditioner or gasoline powered air conditioner is outdated or overhyped. Stick with natural gas or propane furnaces paired with modern SEER2-rated AC systems.
Final Thoughts: What Would Tony Do?
If it were my home, here’s how I’d think about it:
- Need heat + cool? Go with a furnace and central air setup. Gas or propane furnaces give you reliable heating, and pairing them with a system like this Goodman 2.5 Ton SEER2 AC gives you year-round comfort.
- Live off-grid? You can explore propane and even rare gas powered AC units, but don’t expect miracles.

Stay cool, stay warm, and as always—stay smart.
