goodman 14 seer ssx14 vs trane xr 13 seer
Comments (1)As a longtime retired HVAC/R contractor, for a number of reasons I will not list here, I would go with the Goodman 14-SEER SSX14 using R-410A. That comes with a 3-ton evaporator coil with a piston metering device; I would ask for a TXV metering device. I always want the Copeland Scroll compressor with a TXV on the evaporator. Normally you won't need a start kit with that Scroll compressor. Using Goodman's Expanded cooling data, I ran the numbers on a 16-SEER; a 14-SEER will have a little higher condenser temperature split. An 85-F outdoor temp; with a 3-ton evaporator @ 900-CFM & dry bulb 75-F; 51% indoor relative humidity on a 2-ton condenser the condenser temp-split came to 15-F; delivers 23,500-BTUH. That is good for a 16-SEER system. Get a humidity gauge & check other temps as illustrated to see if it comes close to a 15-F split at those listed conditions; if it is "too far below 15-F outdoor condenser split," "at those conditions," it may need some trouble shooting to locate the problems. That is very good performance & illustrates why you need good airflow. A 3-ton coil will tolerate 1350-CFM, therefore 900-CFM is moderate airflow velocity through that 3-ton E-Coil. - udarrell Here is a link that might be useful: Equipment Sizing Duct Sizing & Airflow...See Morebryant preferred 15 seer vs trane 16 seer - help me decide !!
Comments (20)Okay, after getting several quotes, we need some advice on selecting the best system for the best prices out of these 3 following quotes: #1 Steve's Service (A+ Rating BBB) BRYANT 165 A Puron 15 SEER / 2.5 ton 315JAV Evolution 80% /(70 BTU) / variable speed CE (coil) / 3 ton Bryant 7 day programmable / wireless thermostat (technician said that it shows Bryant on stat but not made by Bryant? could not locate this one Bryant web site) 4" media filter replacing all current registers with bar type registers 20 years warranty for heat exchanger from manuf. 10 years on compressor from manuf. 10 years parts/labor from company $5600 minus $400 Bryant rebate = $5200 out of pocket cost $5200 minus $1500 tax credit + $3700 actual cost And, since the Evolution furnace will push up the system the SEER to 16, Steve (tech) told us that we would qualify (with certificate from manuf.) for the $1500 tax credit Is this correct? #2 AC COOL (A+ BBB) Bryant 165 A / 2.5 ton Bryant312(3AV036)80% 2 speed 70 BTU Evap Coil CNRPT 2.5 ton Pro line thermostat 4" media filter replacing all current registers with bar type registers 20 years warranty for heat exchanger from manuf. 10 years on compressor from manuf. 10 years parts/labor from company $5800 minus $300 Bryant rebate Actual cost: $5500 (no tax credit) #3 Air Concepts (A+ BBB) American Standard Model: R410A / 4A7A5030B1000A 15 SEER / 2.5 Furnace: variable speed / AMT2B060A9U3VA / 95% / 60 BTU Evap. coil: 4X4C38/80 Honeywell 8000 thermostat 4" media filter replacing all current registers with bar type registers 30 years warranty for heat exchanger from manuf. 10 years on compressor from manuf. 2 years parts/labor from company 1 year maintenance 1 extra 4" filter $5987 minus $1500 (tax credit) = $4587 $4587 minus $200 (gas company rebate = $4287 So far, quote #1 seems to be a quality system for a good price. We would like to make the decision over the next couple of days. Let me know what system looks the best Are we missing anything here in these quotes? Thanks a bunch !!...See MoreRheem 15 v 16 seer vs Carrier 15 seer
Comments (7)Cas How old is downstairs system? I see no urgency on replacing upstairs system especially since it serves a living area that is not used often. If you haven't done this already, you should a good PM/checkup performed on the upstairs system. I find the Rheem quote on the high side. I don't recommend going up in size unless ductwork has been thoroughly checked especially on size both supply and return to see if it can handle the additional CFMs. Obviously correct sizing is important. If you are unsure, then request a load calculation or even perform it yourself for a nominal fee online. there are three equally important components-quality HVAC, the install by dealer, and probably the most overlooked and disregarded is the ductwork system. 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 line set 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 look at Trane/AmStd,Rheem/Rudd,Carrier/Bryant. Depending on your location, I would not purchase a new HP system that did not have electronic demand defrost. Carrier does not. IMO...See More16 seer 2 stage vs. 17 seer single stage
Comments (2)If you don't oversize the equipment; I'd go with the 16-SEER 2-stage. The SEER Rating when you know how they're formulated doesn't mean that much in most home installation setups; you'd rarely ever get near the SEER Rating due to a lack of all the needed supportive factors!...See Moregaryg
