Carrier Base 80 66K BTU Review

I have several rentals in SD, and over the previous 5 years, have purchased 3 Carrier furnaces (2-Base 80's; 1-Performance 96 w/2 stage burner and multi-speed ecm motor.) All have been superb in appearance, build quality and reliability. My 80's are 14" cabinets and quite attractive units. Easy to clean, work on and super-reliable. 80's often times get a bad rap because they are less efficient that the upper-end models, but may be just the perfect choice for cramped installation quarters or southern climates. 5 years later, I'm very pleased, very happy, would buy again and also recommend to you. For those who may not be familiar with Carrier's lineup, there are 3 tiers of heating/cooling units: Base Comfort, then up to Performance Series, then up to the Infinity. Comfort Series utilize a PSC motor and single-stage blowers/gas valves. They will be a bit noisier than the upper series, but provide a great cost/performance ratio. Consider the Comfort 95 furnace at 95.5% efficiency. All furnaces in the Performance and Infinity lines offer a ECM motor, as well as additional features such as humidity control, etc. The top of the line is the Carrier 98, which is wanted by all but affordable by few. Consider the TP6 as an economical option for it. Please note that efficiency ratings are not across the board; that's why it will state "up to" xx% efficient. Actual rating varies by BTU, cabinet size, etc. Please delve into the product manual to find the exact rating for your specific model number. I hope this short review helps you in your search.
