The Carrier Performance 93 Furnace is a discontinued Energy Star-rated furnace operating at 38,000 to 128,000 BTU/H. This two-stage multi-poise unit had an AFUE rating of up to 93 percent, and the galvanized steel cabinet had a top coat of baked on urethane and polyester for corrosion resistance. It operated with natural gas, yet also was LP convertible.
The Performance 93 employed the company's Comfort Heat technology, which reduced cyclical temperature changes in the home by predicting the need for heat. In addition to the unit's high-efficiency air filtration cabinet and sealed combustion system, it featured a heat exchanger with a Serpentuff polypropylene laminate coating that the manufacturer said enabled the unit to extract almost all of the heat produced.
This unit had a pilot-free Powerheat ignition, a QuieTech noise reduction system and on-board diagnostics to help speed service and maintenance needs. Add-ons, such as the optional humidifier, were available. The Performance 93 was part of Carrier's Performance furnace line.
I had the Performance 93 installed about 3 months ago, What a mistake. A very costly mistake. First, there is the noise level, it wakes me up all night when it turns on. I woke at 0430 this morning from the unbalanced or just poorly made/assembled induction fan noise. When the unit is operating it was causing so much vibration in my office I had to remove pictures from the wall. This was only a temporary setback, you see after the switch that turns the gas on failed the unit shut down and no longer operated. My noise problem was solved, it was 56 in my house, The repairman has been over 5 times (Great service)to fix the problem, you can’t fix a poorly designed product, it is what it is. I now sit in the living room with a $30. space heater and the living space closed off, waiting for yet another fan assembly for my $7500. unit. What a piece of JUNK! I wish there was something to check that was 3 steps below VERY UNSATISFIED!
Online reviews of this unit suggest that The Performance 93 is considered a good unit overall. Among the few complaints posted on online discussion forums is one on ridgelineownersclub.com from a homeowner with a Performance 93 that for the first year after installation worked flawlessly. Soon, however, the homeowner writes that his unit grew increasingly louder and over time the noise was accompanied by strong vibrations. A visiting maintenance technician has repeatedly changed out the inducer motor, having heard this model has an issue with this particular part, but this fix has not improved the rattling noise. Techs posting on this online forum suggest the homeowner have his tech examine ducts for loose parts, the fan blade and connections, the balance of the blower wheel, the blower motor cage and other possible solutions.
When registered within 90 days after installation, the Performance 93's original owner receives limited warranty coverage for 10 years on parts and for a lifetime on the heat exchanger. The secondary heat exchanger comes with a limited 20-year warranty. An optional extended warranty is available and can be discussed with the dealer. If product registration does not take place within the 90 day post-installation period, the unit has 5 years of coverage on parts and 20 years on the heat exchanger.
