We've been with Alaskan Home Services for fifteen years and we've had exemplary service from them after all these years. They come to do bi-annual check ups and have replaced our entire heating and cooling system twice. We've only had one visit that was bad and we contacted the owner in Phoenix and he fixed the problem within 24 hours, which was outstanding.
They're very reliable and provide a great, quality product. They're looking for long term relationships with their customers and we've been pleased since the beginning. We would recommend them, it's rare to find a business that cares this much about their customers or does the same quality of work that they provide.
