Happy customer says
About temperature
control systems inc

I have used Temperature Control at my place of business and for personnel use for over 15 years. Very easy to deal with. Prompt service. Personality says so much about a business and Larry and Alex know how to treat there customers, with a smile and a "no problem we'll take care of it" type of attitude. Would and have recommended them to so many people over the years. Everyone has always been happy.

Best AC service around! Alex was able to trouble shoot and repair an intermittent central AC problem at my home quickly and efficiently. He was knowledgable, prompt and professional. He got the part we needed quickly and had us up and running in no time! Highly recommended. Wouldn't use anyone else.
