We have run both units pretty much 24/7 since early/mid July, they have done a good job cooling whole house versus large window unit cooling just over half of house adequately, barely, also running g 24/7.

On 100+ days we notice temps climb a couple degrees(68 instead of 66, oh darn) late afternoon/early evening. Some of that is a trait of log home.

Cost to operate has been $15-$20 per month during hottest 3 months of the year and negligible the rest of the time.

Total investment to purchase was $3000 and I installed both units myself.

Best quote I got to install a forced air system including AC was $12000(furnace/AC and ductwork). Projected electric cost to operate monthly was $40/month.

Very pleased with result, estimate $200 per month savings for 5 years.

Looking forward to see how well they perform as supplemental heat to wood stove this winter.

If you're unarmed, you are a victim.
