Ordered a 36k condenser, 24k wall unit and 2x9k wall units. Shipped within days and received great tracking info. Everything arrived in perfect condition and is up and running perfectly. Couldn't be happier with the result. Another stockist was charging over $800 more plus tax for the exact same product. Cool mini splits were awesome from day one. Highly recommended

I shop online extensively and have to say best support, hands down. Alex worked to get order out even with part coming from Kentucky after massive tornado not to mention it being a week before Christmas. Line set was lost on the job and without his help I would have been jammed. Don't know much about the company, but with people like Alex, they are doing something right.
