Heating and air conditioners have come a long way in terms of reliability and performance. The most common materials used in a heating and air conditioning systems is copper. While copper has many beneficial properties and is the gold standard in the industry, in certain humid and coastal regions the copper inside the coil and condenser can rust. This leads to performance issues as well as health and indoor air quality issues.
A recent innovation from Lennox is the Quantum Coil system. This system uses 100% aluminum for the coil and condensing unit. The main advantage of this system is that aluminum is more durable and does not rust. If you live in a humid climate or live within 20 miles from the ocean, the Quantum Coil system should be your go-to option for your air conditioner.
