• “As a retired police officer, I am very cautious about who comes to my residence and who works on it. I have used Allstar Air Conditioning & Heating in Rancho Cucamonga on two separate occasions in the past few years. On both occasions their professionalism and thorough knowledge of air conditioning units has been excellent. They have exceeded my expectations and met all my needs. I have been happy with their service and would highly recommend them to everyone. I would especially like to thank Joe for his timely response to my service request and for being able to remedy my problems. I would most definitely use them again in the future!”
