comparing Carrier & Trane AC & furnaces
Comments (15)Since you plan to be in your house less than 5 years, the savings from a 95% furnace wouldn't pay for itself, so the 80% furnace makes sense. Unless future homebuyers care about this nowadays. A heat pump with the 80% furnace would help save on the heating bill (assuming reasonable heating costs) because a heat pump is an efficient heat source down to even below freezing, then the furnace would take over at a specific set temperature or when the heat pump can't keep up (would require a good thermostat like the Honeywell VisionPRO IAQ). But, if the added upfront cost is significant, just a furnace and air conditioner would not be unreasonable given you are not planning on being in the home for more than 5 years max. Ideally for replacements I recommend 95% furnaces with air conditioners or 80% furnaces with heat pumps; but whether you choose an 80% furnace with air conditioner will be your decision based on the circumstances. 80% AFUE, 2-stage, variable-speed is great to have for comfort and would be my recommendation. I believe for the most part this is what you've been quoted (Trane TUD, Carrier 58CVA)....See MoreCarrier vs Trane Two-Stage Furnace - Advice Needed from Pros
Comments (12)One thing a variable speed (as opposed to variOUS speed) blower can do is run at a lower speed on AC in order to perform humidity extraction. My Trane starts very low, then low and stays there for a while (several minutes). It then slowly picks up speed and reaches its highest setting. At shutdown, it slows down quickly then blows at very low for about 30 seconds before stopping. The heat profile is similar though the highest setting is more like medium. A modulating furnace will modulate (or change up and down) the gas flow to match the amount of heat that is needed. A single stage 'regular' furnace is all on / all off. A 2-stage would be off / half / full or something similar. I generally like to think (and others will correct me) that a condensing furnace is so efficient that the gas exhaust temperature is low enough that water vapor 'condenses' in the flue. A less-efficient design would have hotter exhaust and the vapor would not condense but go out the vent....See MoreCarrier AC - Performance Series vs Infinity Series
Comments (3)Carrier's Performance 17 AC is just fine. Warranty is same and this condenser is compatible with Infinity Controls. See below 24APA7 Performance Efficiency Up to 18 SEER Limited Warranty 10-year parts limited warranty when properly registered1 ENERGY STAR� Details All Carrier air conditioner products achieving system combinations of 14.5 SEER and 12 EER or higher meet the ENERGY STAR guidelines for efficiency. Proper sizing and installation of equipment is critical to achieve optimal performance. Air conditioners must be matched with appropriate indoor coil components to meet ENERGY STAR criteria.

We are not planning to move for many years so I can see paying more if I can save significant money/energy over the long term or if it improves the comfort of our home... Also sometimes it seems like newer/high tech have more things that can break or go wrong......See MoreAustin Air Companie
