FAQs

Do I need to replace the furnace too?
Only if it is old or incompatible. If your furnace is under 10 to 12 years and sized correctly, you can usually keep it.

Is higher SEER2 worth it in the Northeast?
Usually not past 16 SEER2. You will not run cooling long enough to recover the premium.

Should I replace the line set?
Only if it is damaged, undersized, or contaminated. A nitrogen pressure test tells the truth.
