Best brand for furnaces and water heaters.
More info needed. Gas or electric furnace? Gas or electric water heater? Tanked or tankless water heater? Why one brand for both? Buy best in class for whatever type of unit you're after. Furnaces you're probably looking at Trane, Carrier (I have a Carrier 80% gas), or Lennox. Tankless water heaters, probably Rinnai, Navien (I have a Navien tankless gas), or Takagi. With gas furnaces, lower efficiency generally leads to more reliability in that they are simpler systems without the condensing. Plus the added cost made it like a 12 year break even for me over the gas savings. With tankless water heaters, buy a flushing kit and learn how to use it. Do it no less than annually, more if you have harder water. Can't help ya on tanked heaters.

Best tankless natural gas water heater?
When building my house, I went with the Rinnai RU199iN for my natural gas tankless water heater. It provides endless hot water on demand and has been very energy efficient so far. I appreciate the digital control panel for its ease of use and the quick response time, even on colder mornings. Overall, it's been a reliable and solid choice for my new build.
