| I'm in the process of getting quotes for a new Heat Pump for our house in the washington dc area which we just purchased. The house is 12 yrs old, dual zoned. The upper level zone is an attic mounted heat-pump. About 1300 sf.
The local contractors are proposing the following systems (all single stage - variable speed AH):
Do i go with Trane based on the proposals? Does it matter if AH is 2.5 vs 3 ton if outside unit is 2.5ton? |

| I think I can answer your 2nd question: No. basically, the 3ton unit can be set (the blower) to a lower speed for the 2.5 coil. I could look, but are these the Xn15 units being spec'ed? |

| The trane outside units are both XL15i. |

| Cisco 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 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. IMO |
