Carrier Heat Pump Replacement

Carrier Heat Pump Replaced

The Carrier Heat Pump never worked right

Sometimes things are not always as they appear, at first glance this looked like a straight forward Carrier Heat pump change out. The ducting is there, the line sets and the electrical. So I took some measurements, took some pictures and went back to the office to work up a bid.


What caught my eye

What caught my eye is what changed everything for me on this project. I noticed the motor HP and amp draw had been changed on the manufactures label. There is only one reason a technician would change motor HP ... duct issues, specifically return duct issues. After talking to the home owner and listening to all the problems they where having It had become perfectly clear ... the unit has never moved enough air.


Just not enough ducting

Unfortunately in this older farm house increasing the return duct work would prove to be impossible, and I am sure that is what the original installation company faced as well. Fortunately American Standard makes a variable speed air handler that can overcome duct issues such as these.

After replacing the indoor unit, outdoor unit and the line set we where ready to test our theory out .. and sure enough the new American Standard air handler performed perfectly.

When you are faced with ducting issues in a situation where increasing the ducting is impossible but you need the air volume? Use a variable speed piece of equipment. Of course there are limits to what these variable speed units can do, BUT they will help dramatically in cases like these.
