New unit constantly runs. Had service out to check things. $170.00 later found nothing wrong! The products from carrier are both the top of the line furnace and heat pump. New filter. Outside temp 90 degrees and the temp never below 75 or 76. Units run constantly. I cant believe this is normal. frustrated on the amt of money i spent for this efficiency. electric bill 100.00 more this month. outrageous... any info would be helpful.
