The Carrier Infinity heat pump has an efficiency rating of up to 20.5 SEER and 13.0 HSPF, and all models and sizes of the Infinity have earned the Energy Star qualification. It is available with single-stage, two-stage and variable-speed compressors, and uses the Silence System II to keep sound levels as low as 56 decibels. The Infinity Touch Control monitors the user's preferences and the outside conditions, and has a Wi-Fi option which allows the system to be managed remotely. A galvanized steel cabinet with a louvered coil guard and baked-on powder paint finish protects the unit from weather hazards.
First Carrier lasted 24 years, no service contract, no issues. Current Carrier Infinity, 12 service calls in 48 months, I am not aware of any component (other than the duct work) that has not been replaced. Maintain a annual service contract, so out of pocket expense has been limited to about $250/year. But tremendously inconvenient to have technicians taking over your home 4-6 days a year, and never know when the next "call technician" message is going to appear on the thermostat. Spent a week this summer waiting for a coil, had to sleep in my car because the house was over 100 degrees.
On my third compressor in nine years. Would expect this from low end units, but not Carrier. Too bad they have gone cheap on the quality. Look elsewhere.
"Carrier Infinity Heat Pump"
Units are defective. Purchase 5-ton and 2-ton for new house constructed in 2007. Warranty ran out this month on most of the parts. I have had to have service calls at least 15 times in 4 years. Replaced main compressor, been through 5 computer boards between both units, two new thermostats (understand they cost $800 each when not under warranty), waiting on new multi-speed fan motor for main unit. If you are planning to purchase these units then don'T. They are very poorly designed, power bill averages $500/month in the summer time so they are not very effecient. Big waste of money. I will never own a Carrier product again.
I've come to the conclusion, too late, that this was a mistake. In less than a month it has had 2 problems. My son also had one installed several months ago and has been waiting for more than a week in 100-plus degree temps for a part. I tried to contact Carrier with a question about something the installer said that sounds either hookey or very troublesome. Their reply was to contact the installer or another installer. Bottom line – no such thing as Carrier Customer Service and no faith in their Infinity system on my part. If I had found this site 6 weeks ago, I wouldn't have a Carrier Infinity System waiting to breakdown. If it goes out again, the installer will be told to tear it out at their expense. Luckily, this state has a lemon law.
"4 Ton Carrier Infinity Running Like a Charm"
I purchased a 4 ton Carrier Infinity heat pump and air handler and it has run flawlessly for two years. The humidity control is outstanding. My average monthly electric bill is running $65.00 a month less on average then when I had a 3.5 ton Trane. The unit does everything but take the trash out on Saturday morning. My neighbor just replaced his 5 year old Trane that has been giving him trouble since it was installed. They found the 7/8" diameter copper tubing was reduced to 5/8" diameter tubing in a very sloppy way and also found a 90 degree large radius fitting that was bent in such a way as to almost close off the tubing. I believe the installation is critical and is the reason for most failures. A competent installer is a must. Maybe even more important then the manufactuer of the unit.
Based on comments from online HVAC forums, the Infinity is considered to be a good heat pump. There are a few comments from people having minor problems, such as cycling issues. Many of the reviewers on hvac-talk.com regard the Infinity as a great unit, though higher priced than most other heat pumps.
