Best type of AC/heat pump unit

texashomeownerJune 15, 2011

I have three heat pump units in my house unfortunately. Looked into redoing the ducts but it was too costly. Replaced one last year with a new Lennox 2T and it works fine for a small area. Now have a leak in the air handler - 7 year old goodman or some other low priced brand - not installed with compressor. Feel it might be best to replace the entire unit and start over. Given two options by local dealer who I like to use - Lennox XP14-036 15SEER - @$5894 1yr warranty labor and I believe 5 year warranty parts from Lennox; or Trane XL15i 15 SEER @$7,220 which comes with 10 years parts and labor warranty. I'm in the dark about all this. May not be here another 10 years (I'm almost 65 and house is too big) but do want a unit which will work correctly - it's for the main part of the house which also has cathedral ceilings. Thanks for any advice.

post the mdl number of the air handlers quoted with the 3 ton Lennox XP14 and Trane XL15i.

these are the minimum specs you should be looking for.
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
10 yr warranty on parts and compressor

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.

I would not purchase a new HP system that did not have electronic demand defrost.

IMO
