Ductless Mini-Split Installation in Salem, OR 97385

“Andrew and his team ROCK!! After waiting several months for our previous contractor to receive their parts for our Daikin mini-split system, I reached out to Ductless By Design and was floored by the response. Not only did Andrew inform me that they had the inventory in stock, but it was a higher quality system at a lower price – AND could be installed “as early as next week, if you want.” In addition to the work being done as scheduled, the guys were efficient, upbeat, personable, easy going, and friendly. We didn’t even have to move anything out of their way other than taking down a few pictures where the units had to hang. If we could give higher than a 5-star rating, we would!!! Thank you for coming to our rescue, Andrew! It’s so nice having this quiet, evenly distributed, and energy-efficient heat in our home.”
