We have used Alief Heating and A/C for 28 years ~ They have provided seasonal maintenance spring/fall every year with qualified and respectful service. Over the years they replaced our outdoor a/c unit and have worked on the furnace to keep it running without replacement. We have never had to make a callback on any service. They have always been cooperative on appointments ~ especially for 90-yr old neighbors for whom they coordinated the appointments with us. We wouldn’t even think to call anyone else, thanx to Mike and all the team.
