👋 Hey there — Jake Lawson Here
If you’re looking at a 5-ton R-32 air conditioning and gas furnace combo for your home, you already know you want serious cooling and heating power. Maybe you’ve got a larger home or need more stable, energy-efficient comfort year-round. Either way, you’re in the right place.
In this guide, I’ll give you the straight scoop — the kind of advice I’d give my own family — so you can make a confident, informed decision.
✅ What Exactly Does a 5-Ton R-32 AC and Gas Furnace Combo Do?
A 5-ton R-32 AC and gas furnace combo is built to efficiently heat and cool larger homes — typically around 2,500 to 3,200 square feet, depending on climate and insulation.
Here’s what you’re getting:
-
5-ton capacity: Around 60,000 BTU per hour of cooling power — enough to tackle hot summers.
-
R-32 refrigerant: This new refrigerant has a much lower global warming potential than the older R-410A standard, making it a more eco-friendly choice (EPA GreenChill Program).
-
Gas furnace heating: Natural gas burns clean and efficiently, providing cozy heat all winter.
-
Matched system: Bundling the AC and furnace together improves overall system efficiency, durability, and performance.
✅ Assessing Your Home’s Needs — BTU, SEER2, and AFUE Ratings
Before buying, you need to understand a few important numbers:
🔥 BTU and Tonnage
Each “ton” of cooling is 12,000 BTUs per hour. A 5-ton unit provides 60,000 BTU per hour — great for larger homes up to 3,200 sq. ft. Be sure to factor in insulation, windows, and sun exposure.
❄️ SEER2 — Efficiency That Counts
SEER2 (Seasonal Energy Efficiency Ratio 2) measures cooling efficiency. Modern 5-ton R-32 combos typically hit 14.5–17 SEER2, and choosing a higher SEER2 can pay off with energy savings over time (DOE EnergySaver SEER guide).
🔥 AFUE — Furnace Efficiency
Look at AFUE (Annual Fuel Utilization Efficiency) to gauge heating. A 96% AFUE furnace converts 96% of its fuel into heat — a smart choice that keeps your utility bills under control (ENERGY STAR Furnace Standards).
✅ Sizing a 5-Ton AC and Furnace — Bigger Isn’t Always Better
A common mistake is oversizing. Bigger isn’t better — it can cause rapid on/off cycling, humidity problems, and uneven temperatures. A Manual J load calculation from an HVAC pro is the best way to nail the right size for your home.
That’s why most experts recommend hiring a pro to do the math. You can learn more about correct sizing in this helpful ACCA Manual J Overview.
✅ Key Features to Look for in Modern Systems
Here’s where you can separate a basic combo from a top-notch one:
⚡ Variable-Speed Blower
A variable-speed furnace fan matches its speed to demand, which means smoother temperature control and less energy use.
🧠 Two-Stage or Modulating Furnace
A two-stage or modulating furnace adjusts its heat output as needed. You’ll enjoy better comfort and less wasted energy.
🌍 R-32 Refrigerant
You’re already choosing R-32 — one of the most sustainable refrigerants on the market. It’s more efficient and better for the environment.
🧭 Smart Thermostat Compatibility
Modern combos often pair beautifully with smart thermostats like Nest or Ecobee, so you can control your comfort even when you’re away.
✅ Installation & Ductwork Considerations
Your new combo will only perform as well as its installation allows. Improper ductwork, poor airflow, or sloppy refrigerant charging can kill efficiency and comfort.
Here are a few key installation tips:
-
Hire a licensed pro who follows local codes.
-
Have your ducts inspected and sealed if needed.
-
Make sure the refrigerant charge is accurate — especially with R-32.
✅ Cost and Rebates — What Should You Budget?
Prices for a 5-ton R-32 combo typically range between $5,000 and $10,000, depending on your region and model.
That said, you can often take advantage of rebates and tax credits for energy-efficient systems. Check out the Database of State Incentives for Renewables & Efficiency (DSIRE) to see what’s available where you live.
✅ Maintenance Tips for Longevity
Your new 5-ton R-32 combo can easily last 10–15 years if you give it a little TLC:
-
🔍 Every Month: Check or replace the air filter.
-
🧼 Every Season: Clean around the outdoor unit to prevent debris buildup.
-
⚙️ Every Year: Have a pro inspect your heat exchanger, refrigerant charge, and electrical connections.
-
🧰 Every Few Years: Consider a duct cleaning to maximize airflow.
