trying to get to final decision for a replacement hvac in dc area
Comments (8)Is the fifth estimate from Hoffacker, which I think I suggested earlier? Their price on the Evolution system is fair for being a top-end system, and I assume it does not include the tax credit. Did it qualify for a Bryant rebate? I assume the Lennox complete setup qualifies for the tax credit as well. I believe you said this quote was from Hottel. It is a nice system, and I suggest having them include a thermostat that can control humidity in the house at no charge to compete against the Bryant if you go this route. I am confused why the Carrier quote would be less expensive with a 95% furnace, or did I misread that? I'm not opposed to the 80% furnace idea since you're in a townhome and townhomes typically don't require much heat (especially if you have two units on either side -- do you?). Plus, venting would pose an issue most likely. Did the companies look at your ductwork and evaluate it prior to proposing the new systems? If you plan on living in the home for another 10-15 years, and you can now get the additional furnace as part of a complete, new matched system with a good warranty for $2000-$2500, then it's certainly worth considering. However, the other argument is that you could see another 10 years out of the Lennox furnace (or could not). I assume the Lennox furnace has been reliable so far in the past. I agree with the XC14-030 and matching coil as a replacement if you do elect to keep the furnace. It's a tough call. If you did go with the full replacement, I'd pick the Bryant Evolution system. You were quoted their best outdoor unit. Make sure you get the CNPVP3617ATA tin-plated coil (ATA). If it's Hoffacker I'd be very surprised if they didn't plan on using this coil anyway. I think their sales rep that I was familiar with is no longer with them actually, and I didn't know this before recommending them. But, they are a good company and I'm sure you got another knowledgeable rep. Now I apologize for my small essay. :)...See MoreHelp with Replacement HVAC decision
Comments (7)There are no Comfort series with a Carrier E Coil that qualify for the energy credit. The Comfort series is estimated to save $23 per year over the Base model, a payback of 65 years ($1,500/$23). And the higher price of the Comfort series is not factored into that payback period. The Carrier dealer is offering 10 year all parts warranty as part of the price. So no difference there. Located is a brick corner at the remotest corner of the house, sound is not an issue and at only 4 dB greater sound rating, I would rather enjoy the dollars saved. I'll have a variable speed fan and Thermidistat to achieve proper humidity control. I have made a note to ask the contractors about the HP option again. We briefly discussed it earlier and the initial cost was high enough that I calculated a payback that was not justified. Given my opinion, FWIW, that electric rates will rise much faster than nat gas rates over the next 10 to 20 years due to the current and expected continued glut of nat gas supply on the market and in the ground combined with the likelihood that this cap and trade energy legislation will pass causing all electric generating companies costs and our bills to rise dramatically, I expect significant savings by using gas relative to electricity, Again, just my opinion, but also my dollars. I hope it doesn't actually happen. But I will explore the HP option again. Thanks for your suggestions.

Comments (3)Thanks very much, tigerdunes. 3 tons makes sense to us because much of the upstairs cooling ends up downstairs, with the result that downstairs remains cool year round despite the dozen downstairs skylights (and six upstairs). We used to have a 5T AC on the downstairs system as well, but when it died we didn't notice downstairs getting any warmer and realized that the 3T upstairs must be cooling downstairs via the staircase, even more effectively than upstairs ironically. So really the upstairs AC is cooling a 3600 sf house (plus 900 sf basement which however remains naturally cool). Cooling efficiency for the upstairs system is important to us because (a) it spends far more time cooling than heating; (b) matter of principle: reduce our consumption footprint; (c) lower operating cost over next 20 years (for us and any subsequent owners of the house).

Comments (12)Mike_Home - Thank you for the answers and advice. Here are some responses and follow-up questions. 1. SEER/EER - your answer is what I had been slowly understanding that these numbers are what drive the efficiency numbers. Rough calculations comparing my older 10 SEER unit to a 14 and 16 SEER unit plus using 1 year of energy bills, show a potential electricity improvement of $184/year for the 14 and $238.31 for the 16. Of course this is all dependent on a quality install as well as proper ducts, etc. as you've outlined in other points. 2. Payback will be uncertain as I was relocated for work. Not sure how long we'll be here and at this point, the energy savings per year is still important. 3. Understood. Before my research, I didn't realize that the furnace played such an important role in airflow. 4. My zoning explanation might have been poorly stated. The gist of what was mentioned, was that based on proper zoning, the more efficient airflow distribution within the home may allow for a 4 ton condenser. The condenser potentially wouldn't have to push air through all of the ducts at the same rate. Does that logic track with your experience? 5. Appreciate thermostat advice and handling all the features, etc. 6. The annual maintenance contract was from the contractor providing the detailed Goodman quotes. Participating in the yearly maintenance contract covers 100% of repair costs (Contractor backed, not OEM), includes a 10 year replacement warranty, and there are no dispatch or service fees for service calls. The replacement warranty is the full replacement of the failed unit rather than just repairing under the 10 year labor warranty with Goodman. If I don't do the yearly maintenance contract, there is no replacement warranty. Ever heard of this? The contractor (Goodman quotes) may have mentioned "calculations" at one point but I don't remember hearing about them doing a manual "J" load calc. As far as I can tell, Title 24 doesn't require the J calc. It does require a duct leak test performed by a certified 3rd party HERS testing company. This is required on ALL HVAC projects in CA. Rebates are only available as part of CA's Home Upgrade Program. This program has required testing and upgrades on items like ducts, whole home envelope, attic insulation, etc. I will go back to two of the contractors and ask them about performing the calculation. I am looking to replace the whole system at this point to make sure the equipment is compatible and most efficient. Goodman is making me increasingly nervous, especially with the Class Action lawsuit that was just set back last week based on a judge's ruling... As for the use of a different coil with the Goodman equipment, it seems to be very common with Goodman quotes (based on board postings like this). I think there is a relationship or commercial connection between Goodman and Aspen to drive the high use with Goodman systems. I don't know the true specs on the Ruud equipment, I was guessing a bit; I will ask for the models, etc. Thanks again!...See MoreAnuj Bhatia
