Frequently asked questions

Can I install the GE Appliances Altitude 28,400 BTU R-454B 208/230V (GS30WB2BEA / 1G3036AD2BEA) myself, or do I need a pro?
GE Appliances Altitude 28,400 BTU R-454B 208/230V (GS30WB2BEA / 1G3036AD2BEA) is built for professional installation: the line set must be flared, evacuated, and charged, which requires EPA-certified refrigerant handling. Installing it outside the manufacturer's requirements can void the warranty, so budget for a qualified HVAC installer.
Will the GE Appliances Altitude 28,400 BTU R-454B 208/230V (GS30WB2BEA / 1G3036AD2BEA) keep heating in a cold winter?
The manufacturer publishes 26,000 BTU/h of heating output at 5F. Rated heating operation extends down to -15 F. Certified heating efficiency is 9.5 HSPF2. Match those numbers against your climate's design temperature - in cold regions, output at 5F matters far more than the nameplate capacity measured at 47F.
What electrical circuit does the GE Appliances Altitude 28,400 BTU R-454B 208/230V (GS30WB2BEA / 1G3036AD2BEA) need?
Published electrical requirements: 230 V voltage, 25 A minimum circuit ampacity, and 35 A maximum breaker or fuse sizing. Confirm the final circuit against the unit nameplate and local code with a licensed electrician.
How far can the outdoor unit be from the indoor head?
The published maximum line-set length is 165 ft. Longer runs than the included set allows typically mean added refrigerant and a pro visit, so measure the planned routing before ordering.
What warranty does the GE Appliances Altitude 28,400 BTU R-454B 208/230V (GS30WB2BEA / 1G3036AD2BEA) carry?
The manufacturer publishes these warranty tiers: Standard: 5 yr parts / no separate compressor term (limited parts warranty); Best case: 10 yr parts / no separate compressor term (registered limited parts warranty). Registration requirements and proof of qualified installation commonly affect coverage, so read the warranty terms before install day.
