Most knowledgable HVAC rep ever met improved airflow efficiency and comfort at comp. price!
I requested bids from Highly recommended local dealers for Carrier, Trane and Lennox for a 14 SEER system to replace 20 year old 8 SEER, go with existing Lennox furnace. I had severe balance problems and the Got three quotes from highly recommended local Carrier, Trane, Lennox dealers to replace 20 year old upstairs AC mated to existing 8 year old Lennox 80% gas furnace. Had major balance issues and no comfort anywhere upstairs, worst was large master suite. Reps for made good recommendation to upsize one supply, but Earl Houghton, with 40 years vast knowledge, recommended multiple changes, including replacing a horrible cobbled together return air plenum that was killing air flow, all at the best price. Henry Evans and Tsuan did an incredible job doing the work. I am now getting roughly 40 percent more efficiency , comfort in every room. Allowing the return air to flow smoothly into the furnace made such a noticeable huge increase in air flow that two older, narrow spaced return grilles were vibrating at a 500 hz harmonic. Quickly replaced them for $7 each at big box and good to go. Would have given up old unit years ago if I knew what Earl and Henry could do for us!
