Read more about LENNOX Heat Pumps
The now-discontinued HP29 split-system heat pump was a member of Lennox's mid-tier product line, the Elite Series. Offering up to 11.5 SEER and 8.2 HSPF, this series was manufactured in nine different models ranging in size and cooling capacity.
The HP29 is promoted by the manufacturer as having operation sound as low as 74 decibels, thanks in part to a quiet direct drive fan and insulated compressor that helps keep those noise levels at a minimum. Reusable service valves that allow for simple maintenance, a corrosion-resistant cabinet and a high-efficiency outdoor coil for effective heat transfer are additional features of this unit.
This model also was designed to fit a number of compatible accessories, including electronic air cleaners, humidity control systems, and electronic thermostats for customizable air quality control.

"LENNOX HEAT PUMPS SUCK"
Our builder happened to install a Lennox heat pump HP29-036-4P, which is one of the worst I have ever seen. We have already had two fans replaced and two capacitors, and the upstairs heat still does not work!!! Do not buy Lennox ever@@!@!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

"Lennox warranty a sham!"
I have an hp29-030-5p and the compressor just went out. They will cover the compressor but not the labor of $895. wtf kind of warranty is that. I can almost buy a new one for that. I urge anyone thinking of buy a Lennox to think again the warranty isn't worth the paper its written on. They obviously spend their money on advertising and backing their product.
Other HP29 Reviews
The HP29 receives mixed reviews across the web. Homeowners on sites such as hvac-talk.com and doityourself.com say their units have needed "nothing but repairs" over the years, while others mention receiving more than 10 years of solid performance.
Troubleshooting inquiries include general component problems, failure to heat, and a handful of reports mentioning failing compressors. Several of these posts also note the system issues have been in older units with more 10 years of use. Costly repairs and service, in addition to limited warranty coverage, are additional consumer concerns with this unit.
Although this unit currently isn’t available from the manufacturer, contractors on gardenweb.com typically recommend Lennox heat pumps to shoppers. High efficiency ratings and quiet operations, they say, make this brand a good choice.
