This was our second time using Quality Refrigeration Services. We have a commercial grade fridge, it's a walk-in beer cooler for a bar and we called them to replace our cooling system. They were pretty prompt with scheduling, they had to order a part for it so it took about 3 days total after I called for them to come out. Their pricing is good and they did the job pretty quickly, we were happy with the outcome. Would use them again.
