3 Ton Heat Pump- Check out these specs
Comments (8)Your home is very similar to mine (although I have a larger finished basement area. I had a 2.5T system, but the ducting was so poor to the upstairs (return and supply) that I ended up having to get 2 systems installed (alternatives were to be uncomfortable with a replacement system or to rip apart the house to redo ducting). My load calc came in right in between 3 and 3.5 tons (thanks to a lot of high ceilings and the addition of skylights) but I have 2 - 2 ton 2-stage Infinity systems. My installer determined that in low stage I would be just fine for sizing. He did point out that the old setup would have been at the limits of a 3 Ton system. The only downside is in order to get all the new ducting and add gas (per the wife's demand) I had to spend a good bit more. Of course, we plan on being here for many years so the investment in comfort is well worth it IMHO. You should really get multiple quotes from a few contractors. Some are better than others and discuss any issues you may have with the current set up. Let them give you different solutions and then armed with expanded knowledge and options make the decision that best fits you....See More5 ton vs 4 ton Heat Pump in Log Home
Comments (4)First of all, it is considered poor forum etiquette to start a new thread when you already have an active thread. Questions that you have not answered in earlier thread. What is the brand, model, size, and efficiency of existing propane furnace? What is its blower size rating? This is important if you are considering just adding on a heat pump with matching coil to existing furnace. If you really require a 5 ton, then this would most likely require significant ductwork modifications to handle the additional CFMs. Has any of the dealers mentioned this? Mighty important. What is your cost/gallon for propane? What is cost/KWR for electric? Tell us about existing problems with current system and location of problems? Basements at or partially below grade have low heating and cooling loads. Tell us about your average temp for both summer and winter? And extremes? What are your inside design thermostat setting for heating and cooling? How did existing 4 ton AC perform when it was working correctly as far as meeting your comfort requirements? The finished basement should have its own separate system preferred or at very least a zoning control. Any opportunity for insulation improvement/upgrade to basement area? I would want to see a separate load calculation for basement zone. Have you seen the load calcs in writing so that you can review? On the software letterhead? Post back.

Comments (22)I am just being forced to buy a new a/c heat pump unit. My 1988 Carrier unit is finally decided to no longer produce cold air as the condenser is failing. I am replacing it with a 2 ton 15 seer Trane unit with a 2 ton air handler. My house is under 900 square foot and I have 6 windows and one set of french doors. The final cost for replacing the old unit and air handler with a new pad, duct work and a digital control is $4700. There is a tax rebate and since my new unit falls under $5000 I will get $1411 of a possible $1500 rebate. And our local electric company here in Lakeland, Florida will issue a $250 credit on my electric bill. posted date 5/15/2009...See More2nd Electric Bill with New 14 SEER Heat Pump
Comments (19)I am reading all these posts with interest as I have now received my first electric bill for a FULL month with my new system. I put in a Carrier standard blower 13 SEER 2 1/2 ton heat pump/AC system with Puron. It replaced a 20-year-old Trane heat pump/AC. It is certainly not an awful electric bill but I was hoping to see a little bit of savings: Oct 07 with 31 days, I used 612 KwH, and avg. temp was 71. In Oct. 06, also 31 days, I used 703 kwh but the average temperature was much cooler: 64. Since I probably used some heat a year ago and I have been using AC this month , I figure these are probably pretty comparable months. My bill is: $88.42. For the year-ago period: $83.37. The price per kwh now is: 10.86 cents per kwh; a year ago, it was 11.03 cents (this was back when we were getting that "reduction" from the enormously high bills, as those of you in Md. will recall). I work from home and so tho I have a programmable thermostat, I never use that function, just adjust. I keep the house as 76 (75 if it is truly awful out) in the summer and in the winter, 72 (again, the truly bitter cold will get me to aim for 73 or 74). I turn the AC off at night most nights and just use a ceiling fan; it is often off during the day as well since I work in the (almost always cool) basement. Nothing else has changed "electrically" here; my hot water, refrigerator, and other power uses are unchanged, nothing is broken, etc. Obviously, I did not purchase "high efficiency" system but I assumed all NEW systems are more efficient and hopefully a little less expensive to run. I guess this was a wrong assumption....See Moremr_havac
