With an 8 year-old system, I would replace the compressor. But not for $2500. Get more quotes on replacing the compressor. Once you replace the condenser with a new 13 SEER, using the old coil may be a problem because its smaller than a matching coil. It also depends on how often you use your a/c. Are you in Miami or Chicago, big difference. Good luck.

load calc,load calc, load calc needed. you need to find a contractor experienced in industrial/warehouse HVAC applications, not residential. IMO

I have owned this Maytag 23 SEER IQ Drive equipment from Nordyne (both a 3 ton & a 2 ton unit)since April 2009. I replaced two old, inefficient systems in their entirety. I paid top dollar for this high efficiency equipment and boy was I taken! Lots of service calls (more in 1 year than in the 11 years I owned the older units); high humidity inside the house (a new problem that started with the install of this equipment); noisy fans that wake me up when the units shut down at night; no improvement in energy efficiency at all (I have to keep the house 4 degrees cooler than with the old equipment to keep from sweating, due to the high humidity); equipment is sensitive to power fluctuations (computer brain flips out every time there is a switching transient from the power company and must be reset); and the list just goes on and on. I would NOT recommend purchasing this product. A Trane 2 Stage system would likely be a much better investment (note: I have never owned Trane equipment and I don't know anyone who works for Trane - it just happens to be the alternative I investigated before deciding to buy the IQ Drive.)

Is the $6900 before or after 500 rebate? It is hard to comment on price because every area has different price pressures and every job has its own challenges. Price is not on the low end but the equipment is good.
