Gibson JT4BD Heat Pump Overview

The Gibson JT4BD is a 13 SEER/8.5 HSPF heat pump designed for single, multifamily or light commercial applications. When combined with a variable-speed air handler or variable-speed blower kits from Gibson’s parent company, Nordyne, units in this series can reach up to 14 SEER with 8.5 HSPF.

This series is available in 1.5- to 5-ton capacities and is sized for either slab or rooftop installation. The JT4BD is promoted by the manufacturer for its durable performance, courtesy of a galvanized steel cabinet finished coated by a polyester urethane and metal guard to protect the coil.

Additional features of this unit include copper tube and aluminum fin coils optimized for efficient heat transfer and a permanently lubricated motor for quiet operation and minimal maintenance.

Gibson JT4BD Heat Pump Reviews

"So many repairs"

1.0 rating
Very Unsatisfied

Purchased in Feb 2011. Unit has had so many repairs. Repairs totaling $2,687 in just 7 years. Accumulator, Schrader valve and txv have all been replaced. And system has had many leaks and had to have more Freon added. Do not purchase this brand. Mine is being replaced tomorrow.

I had my Gibson system installed about 2 1/2 years and have had no problems. It keeps our home very comfortable in the summer and winter. Also, we live on the water (salt water) and the outdoor unit looks as good today as it did the day it was installed. I would not hesitate to buy this brand.



"Great Gibson system"

5.0 rating
Very Satisfied

Bought 13 seer heat pump unit with variable speed motor in Apr 2010 and it has performed flawlessly thru a terribly cold and two hot summers here in MO. Installer was experienced with Gibson installs. Total cost was $3350. Had estimates for American Standard And Goodman that were ridiculously high.

Other JT4BD Reviews

As one of Nordyne’s lower end product lines, many homeowners and contractors do not recommend installing a Gibson heat pump. Reviews indicate that this unit was designed as a builder-grade model and homeowners “get what they pay for” when installing this unit. Several contractors suggest paying more for a reliable and well-known brand.

Despite negative reviews of the brand, some contractors say they have seen very little wrong with this particular unit. Contactors on note no problems out of the ordinary with Gibson heat pumps. One contractor says he believes the fact that Gibson tests each unit on the factory line helps support the brand�s quality. Others mention solid warranty support and customer service as benefits of installing Gibson products.
