I recently had an AC unit installed in a four-unit building I own and I'm starting to feel uneasy about the whole deal. I initially received a quote for a Ruud model RA14AZ24AJ1NA, which boasts an energy efficiency rating of 14.3 SEER2. However, the unit that was actually installed was the RA13NY24AJ1NA, with a lower rating of 13.4 SEER2. While both units are 2-ton and part of the same series, I'm concerned that I didn't get what I was promised. The HVAC guy insisted that the installed model was the way to go, but when I checked, the invoice showed it was around $200 more expensive than the quoted unit. Plus, there were some installation issues that have made me uneasy. Can anyone with HVAC experience chime in on whether I'm being taken advantage of here?

It sounds like the differences you're seeing may just stem from a supply issue. The more expensive R410A units like the RA14 went out of production in 2025, and now it's mostly R454B units available. The slight difference in SEER ratings won't lead to significant changes in your operating costs — possibly less than $300 over five years of continuous use. In my opinion, it's likely not a rip-off; just a case of the HVAC guy using what was available at the time.
Both models you mentioned are part of the same Endeavor line. While the RA14 has a slightly better efficiency rating, it's not a huge leap in performance. The key difference is the refrigerant types used. It seems likely that your HVAC guy just went with the RA13 because it was in stock. So, while it's understandable to feel uneasy, I don't think you're getting ripped off here.
