If you really like the furnace you have now, except that BTU, Lindberg, RTC, Watkins Johnson, MRL, SierraTherm, or someone else has told you that their controller is "obsolete" or "non-repairable," you're in luck!
Furnace Guy offers a controller retrofit that's surprisingly affordable! And, it usually installs in less than 1 hour. We can provide full-installation for you, if necessary. Consider upgrading your furnace controller today!
PLUS, our controller comes with free lifetime software upgrades and is guaranteed to not ever become obsolete, for as long as you own your furnace.
