🌟 Why a Checklist Matters
A 5-ton system is a powerful HVAC setup typically suited for larger homes or homes with higher cooling and heating demands. Because of its size and the newer R-32 refrigerant technology, there are several important factors to review before buying. Missing one detail can lead to unexpected costs, poor system performance, or frustration down the line.
Having a thorough checklist keeps you organized, informed, and ready to choose the system that fits your needs perfectly.
1️⃣ Confirm Your Home’s Cooling and Heating Needs
Start by understanding your home's specific requirements. The "5-ton" rating equals roughly 60,000 BTUs of cooling capacity per hour, which typically fits homes around 2,500 to 3,000 square feet. But square footage alone doesn’t tell the full story.
Factors like ceiling height, insulation quality, window types, and local climate influence your needs. The best way to get a precise estimate is through a Manual J load calculation performed by a qualified HVAC professional. This calculation assesses heat gain and loss to ensure your system is sized correctly — not too big, not too small.
For homeowners who want to learn more about this, the Air Conditioning Contractors of America offers excellent resources on load calculations at ACCA’s homeowner page.
2️⃣ Check the Energy Efficiency Ratings: SEER2 and AFUE
Before you buy, look closely at the efficiency ratings of your potential system:
-
SEER2 (Seasonal Energy Efficiency Ratio 2): This rating indicates cooling efficiency over a typical cooling season. For a 5-ton system, aim for at least 14.5 SEER2, but many R-32 models exceed 16 SEER2 for excellent savings on electricity bills.
-
AFUE (Annual Fuel Utilization Efficiency): This rating applies to the gas furnace and tells you how efficiently it converts fuel to heat. A rating of 95% or higher is excellent and will save you money on your heating costs.
Knowing what these ratings mean for your energy bills can save you money over the life of your system. The Department of Energy offers an easy-to-understand guide to SEER ratings at Energy Saver SEER overview.
3️⃣ Understand the Benefits and Handling of R-32 Refrigerant
R-32 refrigerant is becoming the industry standard for new HVAC systems due to its lower environmental impact and better energy efficiency. It has a Global Warming Potential (GWP) roughly one-third that of older refrigerants like R-410A, helping reduce your home's carbon footprint.
However, R-32 is mildly flammable (classified A2L), which means installers and service technicians must be specially trained and certified to work with it safely. This affects both installation and ongoing maintenance costs and procedures.
For more about R-32 refrigerant and safe handling practices, check out the EPA’s detailed information at the SNAP refrigerant program.
4️⃣ Verify Installation Requirements and Contractor Qualifications
Installation quality can make or break your HVAC experience. Improper installation leads to inefficiency, increased wear, and costly repairs down the line. Because R-32 refrigerant requires special handling, it’s critical that your installer is certified and experienced with this technology.
Before purchasing, confirm the installer you choose:
-
Has certifications to handle R-32 refrigerant safely.
-
Will perform a Manual J load calculation for accurate sizing.
-
Is licensed and insured.
-
Has good customer reviews and solid references.

5️⃣ Review Your Existing Ductwork and Electrical System
Even the best furnace and AC won’t perform well without proper ductwork and electrical support.
-
Ductwork: Leaky or poorly insulated ducts can waste up to 30% of your conditioned air. Have a professional inspect your duct system and seal or repair leaks before installing your new system.
-
Electrical Panel: Larger systems like a 5-ton setup might require an electrical panel upgrade or dedicated circuits to handle their power needs safely and efficiently.
Skipping this step can cause operational problems and safety hazards. It’s best to address any duct or electrical issues before or during installation.
6️⃣ Explore Available Rebates and Incentives
Many local utilities, state energy offices, and federal programs offer rebates or tax incentives for installing energy-efficient HVAC systems, especially those using environmentally friendly refrigerants like R-32.
Before buying, research:
-
Your local utility’s rebate programs.
-
State or regional energy efficiency incentives.
-
Federal tax credits for high-efficiency equipment.
These incentives can significantly reduce your out-of-pocket cost and shorten your system’s payback period.
The Database of State Incentives for Renewables & Efficiency (DSIRE) is an excellent place to start your research: DSIRE website.
7️⃣ Understand Maintenance Requirements and Costs
Maintaining your 5-ton R-32 system properly will keep it running efficiently and extend its lifespan.
-
DIY Tasks: Regularly changing air filters (every 1–3 months) and keeping the outdoor condenser clean.
-
Professional Maintenance: Annual tune-ups are essential, including refrigerant checks, coil cleaning, furnace safety inspections, and electrical system evaluations.
Because R-32 refrigerant is mildly flammable, refrigerant-related work should always be done by certified technicians.

8️⃣ Confirm Warranty and Support Details
Before making your final purchase, carefully review the warranty terms for your 5-ton R-32 system components:
-
How long the manufacturer warranty lasts on compressors, coils, and furnaces.
-
What parts and labor are covered.
-
Whether extended warranties or maintenance plans are available.
-
The reputation of the manufacturer’s customer support.
Good warranty coverage and responsive support protect your investment and give you peace of mind.
9️⃣ Plan for Installation Timing and Logistics
Scheduling installation at the right time helps avoid discomfort and unexpected delays.
-
Consider seasonal demand — spring and early summer tend to be busiest for HVAC installers.
-
Coordinate with your installer about home access, electrical work, and any duct sealing or repair.
-
Prepare your home by clearing the installation areas and informing family members of the schedule.
🔟 Evaluate Your Budget Holistically
The price tag on a 5-ton R-32 AC and gas furnace combo includes more than just the equipment:
-
Equipment cost itself (varies by brand and features).
-
Installation labor and any needed upgrades to ducts or electrical systems.
-
Permit and inspection fees.
-
Potential maintenance costs and warranty coverage.
-
Savings from energy efficiency and rebates.
Planning your budget with all these in mind avoids surprises and helps you choose the best system within your means.
