I just had a 2.5 ton Carrier Comfort Series heat pump and air handler installed in my condo on Friday. The new system replaces a Goodman builders grade that came with the apartment. It cost me a bundle in maintenance and repairs until its demise last week.
The Carrier air handler is noisier than the old one probably due to the perceptibly stronger air flow. I think I can live with the noise level. My concern has to do with an ever-so-slight feeling of clamminess. My indoor humidity (according to an electronic clock/temp/humidity gauge about whose accuracy I have no idea) has been hovering in the 51 - 53%. Outdoor humidity has been in the 70 - 85% range.
I know that I'm more sensitive to humidity that most people, and I plan to give it another week or two to see if I'm just going through "buyers remorse". However, I am curious. I know that the extra power in the air handler might be moving the air too quickly to reduce the humidity into my comfort range. In looking at the Carrier air handler specs I see that the blower has high and low speed settings. I'm assuming that the current setting is high. So my questions:
(1) Could a switch to the lower speed address both the noise and humidity?
(2) What problems, if any, are associated with the switch.
(3) Is it a big job?
(4) Would you consider 50 - 53% humidity an acceptable level?
Thanks for any ideas, comments.
