By now most of our units have been upgraded to the newer heat-pump technology which is saving our residents hundreds already. This post is a review of Carriers 5 ton variable speed heat-pump. If you don't already know, a heat-pump unit operating in the summer, will pull out hot air from the interior and displace it outdoors. Usually A/C units are either on or off. Not anymore! They've basically added a gas pedal to this thing. So instead of on/off the variable speed motor reduces or maximizes air flow based on need. So your unit could be running at 10%, 30%, 80%, or full blown 100%. I psychologically hear you saying through the interwebz, why do I care? Geez man you're such a nerd! Whateva!...Because you'll have more in the Bank... (After payoff of course) Unfortunately we cannot connect our ecobee, but that's OK because we still have control from smartphone access and you can still program zones with additional hardware. If you are in a situation where you are trying to save bank and choosing between adding or changes in insulation type within your structure vs. upgrading HVAC equipment. In my opinion you'll get more bang for your buck on upgrading the equipment. Stay tuned while we watch the savings pile up and will report more results at a later date!
