Carrier 25HNA Infinity Heat Pump Overview

The Carrier 25HNA Infinity heat pump series is available in one- or two-stage units. As a two-stage unit, operation mostly occurs in the lower stage for cost savings. The Infinity heat pump series is designed to partner with the Infinity series furnace enabling the utilization of hybrid heat. Carrier's hybrid heat involves a duel-fuel system in which the system optimizes the efficiencies of fuel sources by switching between electricity and gas. With up to 19 SEER and a 9.5 HSPF heating efficiency, the Carrier 25HNA Infinity series has earned the Energy Star rating.

To minimize noise production during operation while maintaining maximum air flow, the Infinity series employs the Silencer System II, which includes forward swept fan blades among other noise reduction features. The unit produces 69 dB during operation, which is about as loud as the average vacuum cleaner.

The 25HNA utilizes the Infinity Control System for temperature programming and enhanced diagnostics for easy repair. The unit is manufactured with a steel louver coil guard and is made of heavy-gauge galvanized steel for weather protection and durability. The exterior is coated with a baked-on powder coat paint.

"Poor Quality – Minimal Warranty Coverage"

1.0 rating
Very Unsatisfied

I think Carrier quality has dropped to expensive junk status. I have owned 4 homes with Carrier a/C. In three of these we never experienced any problems with the a/C. In 2008 we built our 4th home and specified a 2-stage Carrier heat pump. In Vancouver, British Columbia we haven't had very warm summers lately so the a/c is used about 10 days per year. Our primary heat source is hot-water radiant so the heat pump is usually not used in winter. In June, 2012 the a/c failed to start due to low pressure. Service Technician diagnosed a bad compressor coil. The coil was free but labor and recharge cost me $1900. Some great warranty don't you think for a unit with 20 hours of use?? Well, it gets worse. Today, my boiler failed due to a bad pressure switch. I thought that I would just run the heat pump in heat mode until I could obtain the new switch. Guess what? Upon starting the Carrier hp, I see the dreaded Fault 32 – Low Pressure Switch Open message. Also, the refrigerant sight glass is empty and the compressor unit smells of oil. So, at 6-months after my last coil replacement, do I have yet another bad coil or now something else expensive to replace? I think it is time to replace this Carrier with something I can rely on and that I won't have to take out another mortgage to support repairs. Please take careful note those of you about to invest in a new Carrier!!

"Poor Quality Coil – Minimal Warranty Coverage"

1.0 rating
Very Unsatisfied

We built a new home in 2008 and (Unfortunately) installed a Carrier Infinity heat pump. We have a boiler supplying our heat and have only used this heat pump for ~10 days since installation. As part of my pre-summer checkout, I reviewed the diagnostic codes in the thermostat and discovered a low pressure warning. I called my local Carrier dealer who discovered a leaking condenser coil. The coil is actually a double coil and was impossible to fix given the location of the leak. Fortunately, my unit was still "under warranty." Yeah right! Even though my unit is still "covered," I am still on the hook for $1900 repair labor + "other parts" + $300 diagnosis. Wow! $2200 for 10 days of use. Amazingly BAD Carrier product quality. Amazingly BAD Carrier warranty. I had a similar experience with a US auto in 1980. I've never owned nor ever will own that particular make again. People DO remember poor quality!! Next time I'm buying a Japanese brand.

"Why the Bad Reviews for All Units?"

5.0 rating
Very Satisfied

I don't understand this review site at all. Carrier is a good quality, as are many other heat pump brands, but I can't find one that's got consistent reviews. I was curious about Goodman and saw that they have more unfavorable reviews, but the same is true about Carrier. Are these heat pumps all bad, is it the installation or the mismatching of system to home, or is it the review process? As for my heat pump, I've had a new system installed in a 3-story (with basement) rowhouse for 3 years now. The unit has worked flawlessly – it's a 19 SEER-rated system and I immediately felt the difference since I got rid of a Rheem unit that simply wasn't even designed to pump air up three flights of stairs, let alone that the heat pump was so outdated (almost 20 years old). I like looking at the electric meter and that spinning top simply spun like it wasn't about to take off through the glass enclosure. The cool is comfortable, the heat feels like warmth, and I haven't had an issue so far. It was installed right (by Carroll Fuel) which is something necessary with these systems. Make sure your system matches your home properly and get it installed correctly.
