Ten months of heating in Gardnerville Ranchos
Winter nights here average 24°F, and homes need heat from September through June, ten months of the year. A new furnace has to hold up through that long a stretch, not just the coldest weeks.
Most homes here heat with gas. Any non-weatherized gas furnace built on or after November 19, 2015 has to reach at least 80 percent AFUE by federal rule, and that is the floor a contractor is required to meet, not something extra. Power outages are worth planning for too. Across Nevada, 13% of households went at least 24 hours without power in 2024, and the region has recorded 221 winter storms and 290 damaging wind events over the past ten years.

Nevada requires HVAC contractors to hold a state license.
The Nevada State Contractors Board tests and licenses HVAC contractors before they can legally do this work anywhere in the state, including Douglas County. The license belongs to the contractor, not to any single job, so it follows them from one furnace installation to the next rather than being issued fresh each time.
For a furnace install, that license is what stands behind the person in your house, but the job still gets a second check. Most cities and counties require a permit for a furnace replacement, along with an inspection once the work is done, and that inspection is where a bad gas connection gets caught before it becomes dangerous. With most homes in Douglas County heating with gas, that inspection is not paperwork, it is the point where someone independent looks at the line running to your new furnace.

- What size furnace does my house need?
- There's no single number that works for every house. Sizing depends on the square footage, how the house is insulated, how many windows it has, and its layout, so a contractor needs to run a load calculation rather than guess from square footage alone. Here, with winter lows averaging 24°F and heat needed from September through June, getting the size right matters more than in milder places. Too small and it runs constantly without keeping up. Too large and it cycles on and off, which wears it out faster and leaves rooms uneven.
- How do I know it's time to replace my furnace?
- Watch for uneven heat, rising bills without a clear reason, or the furnace running longer to reach the same temperature. Repairs that keep coming back, or a repair that costs a large share of what a new unit would, are usually the sign to stop patching it. Age matters too. An older furnace is working harder than it used to, and with heat needed here from September through June, that strain shows up fast. If yours is a non-weatherized gas furnace built since November 2015, it's already required to run at 80 percent AFUE or better, so an older, less efficient unit is a real difference in how much gas it burns to do the same job.
- Is a high-efficiency furnace worth it?
- It depends on how long the house needs heat and what the furnace it's replacing was running at. Here, homes need heat from September through June, so a furnace is working most of the year, which gives a high-efficiency model more time to make up ground on gas use than it would somewhere with a short winter. Most homes in Douglas County heat with gas, so the fuel a furnace burns is already the main cost for most people here. A contractor can look at the specific house and the furnace being replaced and say whether the jump in efficiency is worth the difference in equipment.
