Recent Testimonial

"This is my 2nd ductless system and I know how hard it is to find someone who knows the technology or even what to expect in heating ones home. After 8 bids on this current system it became obvious that Leslie, Evergreen States heating consultant/sales person, knew her product, cared about what the customer needs and wants were and could offer various options and considerations. For example: the only representative explaining that the electrician could replace some existing breakers with smaller ones in the older panel so as not having to give up existing electric wall units for backup heat. Same product as other bids but she knew various current Mfg. discounts which varied between available models. The quoted cost was on the lower end of all 8 bids. The actual install was smooth with no issues. There was no push for up-front payments or immediate full payment. They handled all the permit applications and pud rebate paperwork. System has worked perfect from the start and after a month there have been no problems."
