A modulating gas valve is an advanced component in a furnace that can adjust the amount of gas burned in tiny increments, rather than just being "on" or "off." This allows your Mobile Home Gas Furnaces to run at exactly the speed needed to maintain a steady temperature, leading to incredible comfort and energy savings. When paired with a variable-speed Air Handler, a modulating valve provides the most precise heating possible today. You will find this technology in our top-tier ACIq heating systems, where it eliminates the "hot and cold" swings of cheaper units. While more expensive upfront, the modulating valve reduces fuel consumption and operates much more quietly. It is the high-efficiency alternative to traditional "single-stage" or "two-stage" gas valves. If you value a perfectly steady indoor climate, this is the technology you want in your furnace. It represents the pinnacle of modern gas-fired heating performance.
