Air 1 Heating and Cooling takes pride in our heating and air conditioning expertise. We ensure optimum quality and customer satisfaction, with every project. Call us for a free estimate on direct replacements and new installs of equipment. We offer 24 hour emergency service.

"They installed our unit in March 2015, and the unit induced motor was found to be defective in Nov 2015. They not only charged us for the service call but also charged us for the part which was under warranty. It was very unprofessional. The same part after less than 5 years failed again, and they took no responsibility for their workmanship. Customer service Person does not deal with the customer on the request. This time again they were charging us for the defective part and exorbitantly for the service call under the pretext that we did not sign a maintenance contract with them. So we did not finally go with them but went with another vendor who is far better and professional."
