👋 Hey, It’s Mike Sanders — Let’s Talk Real HVAC Costs
If you’re shopping for a new air conditioner and gas furnace system sized between 3 and 5 tons, you probably want a clear answer to one question: How much is this really going to cost me?
I’m Mike Sanders, HVAC tech and installer with 20+ years in the trenches. The truth? HVAC pricing isn’t a simple one-size-fits-all number. Costs vary widely based on equipment quality, installation complexity, region, and extras like ductwork or smart thermostats.
In this guide, I’ll walk you through every angle of pricing for a 3–5 ton system, so you’re prepared and know what to expect.
🔍 What Does “3 to 5 Ton” Mean Anyway?
First off, a ton in HVAC isn’t weight—it’s cooling capacity. One ton equals 12,000 BTUs per hour. A 3-ton system cools about 36,000 BTUs/hr; a 5-ton system about 60,000 BTUs/hr.
Most average homes between 1,500 and 3,000 square feet need systems in this range, depending on insulation, climate, and layout.
Sizing matters because an undersized or oversized system wastes money and energy. Make sure your installer performs a proper Manual J load calculation—you can read why that’s essential on the ACCAs website.
💸 Equipment Costs: What You’re Paying For
1. Air Conditioner (Condenser) Unit
Prices for a 3–5 ton AC condenser typically range:
-
Budget units: $1,500–$2,500
-
Mid-range: $2,500–$4,000
-
Premium/high-efficiency: $4,000–$6,000+
Higher SEER2 ratings and newer refrigerants like R-32 will push prices higher but can save you money in energy bills over time.
2. Gas Furnace
Furnaces are priced based on BTU capacity, AFUE rating, and brand:
-
Basic 80% AFUE furnaces: $1,200–$2,000
-
Mid-range 90–95% AFUE: $2,000–$3,500
-
Premium 96–98% AFUE: $3,500–$5,000+
A furnace with a higher AFUE rating is more efficient and may qualify for rebates.
3. Air Handler / Evaporator Coil
This component usually comes with the AC or furnace but can cost an extra $600–$1,200 if purchased separately.
🛠️ Installation Costs: What Does It Take to Get It Done?
Installation includes labor, permits, ductwork, refrigerant charging, and electrical work. Prices vary by location and complexity.
Typical installation cost ranges:
-
Basic replacement (same location, minimal ductwork): $2,000–$4,000
-
Complex installs (duct modifications, electrical upgrades): $4,000–$7,000+
If you need new ductwork or a larger electrical panel, budget extra.

💡 Additional Costs and Factors to Consider
1. Ductwork Repairs or Replacement
Leaky or undersized ducts reduce system efficiency and comfort. Repairs or new ducts can add $1,000 to $5,000.
2. Thermostats and Controls
Smart thermostats add $150–$500, plus installation. They improve efficiency and control.
3. Permits and Inspections
Local codes may require permits costing $100–$500.
🔄 Rebates and Incentives: Lowering Your Bottom Line
Many utilities and governments offer rebates for high-efficiency HVAC equipment or systems using environmentally friendly refrigerants like R-32.
-
Federal tax credits may apply, especially under recent energy legislation.
-
Utility rebates vary by region and program.
Check the Database of State Incentives for Renewables & Efficiency (DSIRE) for up-to-date rebate info.
📈 Operating Costs: What to Expect Year After Year
Your upfront cost isn’t the whole story. Efficiency affects your monthly bills.
-
A 14.5 SEER2 system typically uses about 30–50% less energy than older models.
-
A high-efficiency furnace with 95%+ AFUE can save hundreds yearly on heating.
The U.S. Department of Energy explains how to estimate these savings and the value of efficient HVAC in their Energy Saver guide.
🧰 Maintenance and Repair Costs
Don’t forget ongoing costs:
-
Annual tune-ups run $100–$200 and keep warranties valid.
-
Repairs average $150–$600 per visit depending on part.
-
Proper maintenance extends system life and cuts surprises.
