Nordyne IQ Drive vs Carrier Infinity Greenspeed

[tedkidd]

AWESOME! How exciting. Couple clients with them, they LOVE em.

Will you please periodically share energy and comfort results over the next year?

Is there a reason you didn't go with the new wifi control?

You know what? I actually mis-stated the P/N on the control. I was typing from memory of an earlier quote and when I went back to look, the proposal I signed DOES specify the new touchscreen wifi control. I had to ask the contractor if he had the right p/n because I wasn't aware there was a newer control and I was expecting to get the older model. I was really surprised when it turned out I'll be getting the new one!

Post your static numbers after job is done. Is this one the thermostats can display?

Yes, the control has a "hidden" menu for installation & service where you can display equipment status, including static pressure.

Been without air & heat since my Rheem hp died on October 19th. Luckily, haven't needed either due to Florida's mild temps right now.

After much research and lots of advice from the pro's on this forum, I signed a contract today for installation on Thursday. I sincerely hope I don't regret going with a 3-ton, against the advice of four different pro's who actually completed

Install took a little longer because the condenser came damaged from the distributor's warehouse. The damage was discovered when it was unwrapped and the contractor had to drive about 50 miles to Orlando to pick up another. Besides this delay, the install went very well. They were super professional and did a great job, even with me watching everthing! I'll post some pictures tomorrow.

Static pressure reading is 0.38.

Looking forward to the install pics !!
I'm willing to bet the 3 ton will be more than enough for your house

Im not familiar enough with the infinity line to know if that static reading was

A) total static or just supply.

B) was that at full cooling speed? And what is the full cfm programmed ?

That's low. It must be whisper quiet

A) Total static at the coil.

B) At max cooling speed (1200 cfm)

Yes, it's whisper quiet inside and out!

Noise levels are something rarely considered when upgrading HVAC systems. I was surprised how quiet mine is compared to my old one. When my neighbor's unit is running I can't even tell if mine is running or not w/o physically looking.

Sweet.

SWEET!!

And any other observations?

Of course, it's November.


With a 0.38" static, I believe that air distribution and new air handler capabilities will minimize any temperature imbalance.
+ FL coastal temperatures are not the extremes seen in central U.S. this summer and in Dallas area many years.

It will be interesting to be informed of any Relative Humidity improvements. ( reference post #14)

> 95'F would be rare in Most FL locations, except infrequently near Orlando.

.:. ... NO guarantees in a climate changing environment.

Hope you included fresh air and humidity control when there is low/no cooling loads.
This is a complex expensive system but this type of system needs significant cooling load to remove the moisture from the occupants and adequate fresh air ventilation. A small ventilating dehumidifier would make the system complete.
Keep us posted.

FL Mother Nature provides an abundance of the nice humidity control
in the next 6+ months with
cool mornings like today. 45'F Dew Point
