Welcome to the Allied HVAC Distributors Technical Service page.

Have a technical or service question on a product purchased through Allied HVAC distributors? We provide customer access through our Technical Service Manager. At some point all technicians need a little help and we will always be there to support our customers, as well as the products they purchase from us. And to help you, our contactor customers, in the most effective and efficient way we encourage you to complete a startup sheet on all installations. By completing this double sided sheet you insure the system is performing at its best, within allowable design parameters and you have documentation that the system was started correctly.

In addition to the startup sheets for either a residential or commercial system we have customized troubleshooting forms that can aid a service tech in identifying the cause or causes for a system not performing properly. Please download and use them as you see fit to support your customers and the products you install. At your request we can also customize these forms to add data specific to your company or we can customize the form by adding your company logo. Having a completed data, troubleshooting or startup sheet on hand when calling insures we can provide the fastest, most accurate technical support possible.

Please contact our Technical Service Manager Kris Crivaro at (336) 668-9240 or via email at This email address is being protected from spambots. You need JavaScript enabled to view it.  for your technical support.
