I've been working with Alaskan Home Services for over ten years and they've been nothing but great. They've installed a heat pump and air conditioning unit and since I have a contract with them, they come out once a year and inspect our heater and air conditioner. The service people are very knowledgeable and friendly and their prices are competitive. Before using them, I received several estimates from several different companies and they seemed to be the best. If you're thinking about using Alaskan Home Services, I wouldn't hesitate!
