  • DIY Success
Size: 25 Feet Lineset
I have no prior hvac installation knowledge and this was the largest DIY project I’ve done to date but it got done with only a few minor hiccups that were more so from my lack of experience. The unit is working great so far, I only lightly tested the A/C mode since I installed in fall but I’ve had the heat running with outside temps in the low 30s and it keeps my poorly insulated 1920s home at a constant 70 with about 3 hours of runtime per day. The real test will be in the depths of January when the lows gets into the single digits but I don’t think it’ll have any issues, I’ll update this review if so. There are some key differences I’ve noticed from my old system (1990s natural gas furnace) first is the fan will kick on and blow cool air for a few minutes until the coil has time to heat up, it’s not nearly as instantaneous as gas. Same with when the hear turns off the fan runs for 5 minutes and the last couple minutes the coil gets cold which again blows not heated air. On the plus side this unit is super quiet, both the compressor and air handler are whisper quiet and the fan blows way more than my old fan. Overall I really like this system so far, seems well built and fairly straight forward to install, although the installation instructions could definitely be improved. Installation tips: -GET NYLOG BLUE! I’ve read way too many reviews of couplings leaking and this stuff prevents that. -don’t force couplings, get things lined up perfectly so you don’t have to hold down while tightening. -thermostat wiring is weird pay close attention to it. Instead of using 7wire for the compressor to air handler use a 2 wire to save $. -You’ll need crows feet to attach to the torque wrench I think it’s 1”3/8 for the big coupling and 1” for the small. Would be cool if the manual told you this they aren’t easy to find. -air handler is 220v so you need a two pole (thick) breaker for it. I tried to use my existing 15amp tandem breaker and that’s just my inexperience showing -don’t buy the “frequently bought together” wiring harness whip, it’s the wrong size for the condenser unit knockout hole (need 1/2”) ... show more

  • Easy install.
Size: 25 Feet Lineset
Ok. After 7 months this is our results. We did this as a FIY. We originally hooked it up to our old duct work which was old our house was build in the 1800s. The duct work was metal with no insulation. We got heat but not much. The heat pump ran constantly. Our electric bill went up almost $400. I was disappointed. But then we went out and got all new fiberglass duct work ( trunk line, 6 inch flexible duct) and also added two more vents. After we did the upgrade to the system. The heat pump works great. Our electric bill has leveled itself out by only going up about $135 a month. Might want to get a electric back up or another heat source because when it gets around 10° out the heat pump works but it runs forever. Plus we got a tax incentive about 30% of the total cost when we did out taxes for going to a heat pump. ... show more

  • Exceeded Expectations
Size: 25 Feet Lineset
I'm very happy with the results of this unit. The Heat pump works amazingly well compared to the older carrier heatpump. The lines were very hard to bend without damage and I would suggest have a line-set with elbows where needed installed. The unit is very quiet and worked with my Nest Thermostat. Do not rely on the online manuals as they are out of date. Be sure to use the small included manuals. One thing I got hung up on was there was no spot on the terminal block for the Y wire and the directions were not clear. The Y wire from the thermostat needs to be connected to the Y wire on the outside unit. There is no place in the air handler for this wire to be connected. Followup as of 4/16/2023 - If you live in a humid area this unit may not be the best solution. You will need to install a dehumidifier to keep the humidity down. The fan runs a full 5 minutes after the compressor stops resulting in the air handler dumping all of the humidity it removed during cooling back into the living space. the extended fan run time runs well beyond extracting the last bit of cold out of the A coil and just dumps the wet air back into the conditioned space. I would suggest looking for a system that the thermostat controls the fan and not the unit itself. ... show more

Size: 50 Feet Lineset
Installed easy I'm 65 years old and I did it solo except putting the airhandler in the attic. The 3/4" line is hard to work with very stiff. My old unit was not installed the best. They took alot of short cuts. But do it right you will be pleased with your finished product.. super quiet runs great have been running it for 2 weeks now late fall so didn't get to use the AC very much. Every thing seems to be built to last. Will update my review in 6 months ... show more
