Icon Property Management

Applied has been one of our trusted service providers for many years.  They have worked with us to maintain our mechanical systems in multiple properties. With their expertise, we were able to upgrade our building mechanical and control systems which reduced electrical and gas consumption and ultimately reduced annual operating costs. Utility incentives were arranged by Applied to help fund the upgrades.  Applied has been a valued service provider for anything HVAC related.
