A Message To Our Customers

The HVAC industry has experienced significant equipment shortages throughout 2021. Unfortunately it is projected to continue throughout 2022. In addition we saw multiple price increases, in some cases eclipsing 25% with another manufacturer price increase scheduled for January 1, 2022.

Early 2021 Desert Diamond made a decision to ensure we would have product availability and made a significant HVAC equipment purchase. This proved to be a very wise move as it allowed us to take care of our new and existing customers.

While our strategy was sound it was not perfect and we have arrived at year’s end with slightly more HVAC equipment than we need.

For a limited time we will be offering these BRAND NEW heating and cooling systems at significant discounts as compared to everyday prices.
