I currently have 3 older central air conditioning units that are still working, but we are living on borrowed time.
I want to replace all 3. We will live in the house for at least the next 25 to 30years barring any major catstophies.
We live in the Dallas/Fort Worth area.
Which is a better unit? Carrier or Trane
Is it wise to go with a veriable speed compressor or 2 compressors.
If we plan on staying in the house a long time, does it make sense to get a 20 SEER unit?
