3 Ton Goodman 17.2 SEER2 R32 Two Stage Central System GLXT7CA3610, AMVT36CP1300 Variable Speed
This package brings Goodman's premium two-stage technology to the most popular residential size. It pairs the GLXT7CA3610 two-stage R-32 condenser with the AMVT36CP1300 variable-speed air handler, AHRI certified at 17.2 SEER2 (#215865742). Mid-size homes get long, quiet low-stage cycles on mild days and full 36,000 BTU/h capacity on the hottest afternoons. The variable-speed blower is designed for improved humidity and comfort control. It's a strong pick for homeowners replacing a 3 ton system who want the quietest, most refined comfort in the R-32 lineup. It's cooling only, with optional field-installed electric heat.
Is a 3 Ton Air Conditioning System the Right Size?
Three tons (36,000 BTU/h) fits many mid-size homes. That's often around 1,500–1,800 sq. ft. as a loose benchmark, and it's the most common size in existing homes. With a two-stage system, the right tonnage matters even more. Low stage handles most of the season, so the high-stage capacity should match your hottest design days.
Look at attic insulation, window area and orientation, duct leakage and how humid the home gets in summer. Homes that struggle with humidity under a single-stage system often benefit most from two-stage operation and variable-speed airflow, provided the system isn't oversized.
Ideal for: Mid-size 3–4 bedroom homes, humid-climate homes and 3 ton replacements where owners want premium comfort and quiet operation.

Recommended home sizes are general guidelines only. Actual system requirements depend on insulation, climate, windows, ductwork, occupancy and a proper load calculation. Request free sizing assistance, contact Budget Heating, or call 813-885-7999.

Frequently Asked Questions
What are the low and high airflow settings of the AMVT36CP1300 on a 3 ton?
Goodman's airflow data lists 804 CFM on low stage and 1,200 CFM on high stage when paired with a 3 ton outdoor unit.
Why does the GLXT7CA3610 need a suction line adapter?
Goodman specifies a 7/8" suction line for a 25 ft. line set, but the unit's suction service valve is 3/4". Any adapter must be supplied in the field.
How does a two-stage compressor help with humidity?
On low stage, the system runs longer, gentler cycles instead of short blasts at full capacity. That gives the coil more time to remove moisture, and the AMVT's variable-speed blower is designed for improved humidity and comfort control.
What diagnostics are built into this 3 ton system?
The GLXT7CA3610 includes Copeland® ComfortAlert™ diagnostics and Bluetooth access through the CoolCloud™ app. The AMVT36CP1300 adds a CFM indicator and recall of the six most recent faults.
What warranty covers the GLXT7CA3610 compressor?
With online registration within 60 days of installation, Goodman offers a Lifetime Compressor Limited Warranty (for as long as you own your home), a 10-Year Unit Replacement Limited Warranty and a 10-Year Parts Limited Warranty. Registration isn't required in Florida, California or Québec.
Can I use a conventional non-communicating thermostat?
Yes. The GLXT7CA3610 has a color-coded terminal strip for non-communicating setups. Communicating mode unlocks ComfortBridge™ features such as automatic airflow and tonnage configuration.

"SEER2"stands for Seasonal Energy Efficiency Ratio 2. Specifically, SEER2 is the total heat removed from the conditioned space during the annual cooling season. The M1 testing procedure will increase systems' external static pressure by a factor of five to better reflect field conditions of install equipment. With this change, new nomenclature will be used to denote M1 ratings (including EER2 and HSPF2).
