We maintain, repair and replace all brands of air conditioning systems

D&H AC provides Tucson homes and businesses with air conditioning repair, A/C maintenance and A/C installation services since 1959. Our NATE-certified technicians are trained to repair air conditioning systems of any brand and any age, in a rush and all year long. When your system needs repair, we can perform an audit of what went wrong, so that the true cause of the failure be accurately detected and fixed. This saves you money from further repairs. If you call us to enquire about a new A/C installation, we will automatically perform an audit of your current air conditioning system and its usage to determine with you what AC system is best-suited to your needs over 3, 5, 10 and 12 years. Lastly, we provide top air conditioning maintenance services, with NATE-certified technicians and the Daikin Comfort Pro (TM) ultra-selective label.


We always strive for improvement and we also appreciate praise. Reviews are your voice to tell us how we did. Please take a moment to cast your vote on any one of these four websites…
