Variable Speed blower in HVAC thoughts opinions

Do you mean a 2 stage or is the variable speed something different?

Interesting. I have carrier 2 stage units in my home and live them. I like how I can set them to run at both a temp point and a humidity point. This looks like an advancement from that technology

I've only used them in industrial applications, but they are definitely more efficient, by alot.

So you can match a single stage condenser with a Hyperion air handler, the TAM9 for instance can be matched up with an XR14, or XR16. But for pricing purposes we offer a less expensive variable speed air handler option that isn't Hyperion. They are designed to be much quieter than single stage. But they do run for longer periods, they just use less energy and only run "just enough" to maintain the desired temperature.

Thanks

Not a hijack at all. Every home I go to, I run a heat load (manual J). The app I use is designed by Trane Engineers, which allows me to custom design a new system for any home. To answer your question, high humidity is one of the main struggles we deal with here. If the home is sized properly, then there is no need for a dehumidifier. However, that is not always the case...the answer to that is variable speed, whether it's Trane or another brand. The key is knowing/understanding how it operates. It runs for a longer period of time than your standard single stage system, but it's running at a lower capacity. So say you have a 4 ton system.. you're not getting all 4 tons at once with a variable speed system. The moisture is removed from the air, and the dry air that is left is what's cooled. When I present my options to my customers, generally I call the Variable Speed system the "Dream Machine"...due to how efficient it operates, as well as how comfortable it will make the space.
