“I have worked with Delta since 2009 when I was helped by Marty with an ERV system. Recently I have had the pleasure of asking them twice to help out in 2026 with two ERV systems in two houses. Both cases were installations one a replacement and the other new install. ERV or energy recovery ventilation systems are still quite new for residential properties but becoming more appreciated. They take stale house air from usually toilets and cooking areas, pass it through a heat exchanger and filters before it is exhausted through a vent. In coming air passes through filters and the heat exchanger transferring energy in the form of heat or reducing humidity. The heat exchanger is the heart of the system but since the 2,000s German fan motors have made higher pressure and comtinuous use possible. It saves money and provides filtered drier air.
Delta have been working with these systems and have a reliable knowledge base. They are friendly and easy to work with. A big thank you to Ford and Kylie for all their help.”
