A Furnace Built for Ely Winters, Not Texas Winters
An undersized furnace runs constantly and still leaves rooms cold on the worst nights. An oversized one short-cycles, wears out faster, and wastes fuel all season. Getting the size right is the single most important part of a furnace installation, and it's where cut-rate installers cut corners.
When Replacement Beats Repair
- Age 15+ years — efficiency has dropped and major parts are wearing out together
- Cracked heat exchanger — unsafe to run; replacement is the only real fix
- Repair costs exceed ~1/3 of new — the math favors starting fresh
- Skyrocketing fuel bills — an 80% furnace vs. a 96% furnace is real money over an 8-month heating season
- Frequent breakdowns — two or more repairs in a single winter is the warning sign
Fuel Options for Ely Homes
Natural gas
Where gas lines reach, it's usually the cheapest to run. High-efficiency condensing gas furnaces hit 95%+ AFUE.
Propane
Common in outlying areas and lake cabins. Propane furnaces cost more per BTU than gas, so efficiency matters even more — we recommend 95%+ units for propane.
Heating oil
Still heating many Iron Range homes. Modern oil furnaces are far cleaner and more efficient than the old units they're replacing.
Electric
Simple and reliable, best for smaller spaces or as backup heat. Operating cost is the tradeoff in a climate this cold.
