Need advice on hvac as cancer patient coming to my home in 3 week
Comments (2)tomylake I would not zone the upstairs area. You would probably get better airflow though if air handler was relocated to attic. I assume current arrangement is a chase from crawlspace to attic ductwork and ceiling registers for 2nd floor area. is this correct? I would proceed with return modifications for upstairs. If you are happy with current comfort for 2nd floor, then keep new air handler in crawlspace. I would address issues for heating/cooling finished basement area off main floor system separately. Zoning controls may be a possibility and/or improving supplies and return to this area. Obviously needs an evaluation by experienced dealer. I have to admit that your issues are difficult to advise and solve without an onsite inpection/assessment. I would lean on your dealer for best advice as long as you have confidence in him and he has demonstrated experience in zoning/zoning controls.

Comments (12)crazy these are my minimum specs for a new HP system. both outside and inside units should be replaced to have a properly matched system. 15 SEER, 12.5+ EER, 9 HSPF best matching VS air handler full BTUs in both cooling and heating for your rated size R-410a refrigerant(same as Puron) scroll compressor preferred electronic demand defrost preferred thermostat with "dehumidify on demand" feature staged backup heat strips new and correctly sized refrigerant lineset you want a thorough inspection of your ductwork system. size, overall condition, supply and return lines, insulation qualities, leak test, etc. any hot/cold spot issues in your home should be addressed. I would only use authorized dealers for the various brands that provide quotes. see mfg websites. I would not have either the XL16i or AmStd counterpart Heritage 16. I would stick with the XL15i or XR15. I would also look at the AmStd Heritage 15. I am not a fan of two stg equipment because of added upfront cost and marginal improvement in comfort and operating cost. Look at the PerfectFit media cabinet over the CleanEffects. IMO Good Luck!...See MoreAdvice needed for replacement HVAC
Comments (4)THANKS to ryanhughes for the quick response! Sounds like you are a proponent of the load calc - makes me feel better. The issue we have w/ duct sizing is that so little of it is accessible. Just finished a major remodel and I'm not up for tearing up walls, floors, etc. Too bad the unit d/n blow 6 months ago. I think the guy who made the comment about the high-eff. units not being good for our cut-up house was a veteran who assessed that we have a LOT of ductwork, and it will take a high fan speed to move enough air through all the ducts for us to feel it. He didn't do any calcs to back that up. That's prob. why the prev. owners installed the 5 ton "beast" as one rep called it. Pls. let me know if that still sounds like too much gut and not enough science. I don't have a lot of specific model #s, but I will get on that. One estimate proposed the Lennox G71 furnace that would qualify for the $1,500 rebate regardless what we do for AC, combined w/ a 14SEER Lennox AC. He said he would do a load test to right-size before we signed the contract. I'll provide more $$ once the last guys have bid. Thanks so much for your input!...See Moreneed advice about hvac replacement in north fl
Comments (4)I do not know what size our existing heat strips are. I am assuming the lowest possible, it is the same unit the builder placed in the home and it doesn't appear the original home buyers upgraded much. No idea about heating the place yet, we just moved into the home in March and our winter months here last year were very mild so I think we already had the a/c on. As far as cooling goes, we do not spend a lot of time up there yet. Our master is downstairs and the loft area is in under construction. It does not ever feel very cool to me but I really think this more impacted by the large windows in the great room and high 20 ft ceilings that open up to the loft as well as the age and capacity of the unit. I received another quote from another company here in town and the gentleman recommended the XR15 as a cost effective alternative to the XL15i. The quote he provided included replacing our downstairs system as well (both up and down with XR15's, 2.5 ton for upper and 3.5 for lower with variable speed handlers and Honeywell thermo) and didn't break up the prices in two. The total cost was $10k. I cannot get to the estimate right now to provide part numbers. However, I am now completely confused as he did not include a separate line item for the heat strips? We also discussed upgrading the insulation in the attic space because of the cooling issue etc. He confirmed what I origianlly thought and that is the insulation is the minimal for the standard back in 1999. He oprovided a quote to upgrade with R-38 of around $1800.00. I feel like the more I try to learn about the HVAC system the more confusing it gets. What exactly is the function of the heat strips? Is there any reason his quote wouldn't include a line item for same? Thanks for your help....See MoreMaureen Burgess
