Two months of real heat, then it sits idle
Fernley only asks for cooling in July and August. That is a short season, but afternoons average 87°F through it, and a new system has to be sized to handle that heat on the day it matters most, not just get through most days fine.
Wind is the bigger factor over the life of the unit. Lyon County has logged 305 damaging wind events over the past ten years, and an outdoor condenser sits outside taking that directly. Any new install should go in secured for that, not just set on a pad. New central air conditioners are also held to a federal minimum of 14.3 SEER2, so whatever goes in will meet that baseline.

Nevada requires HVAC contractors to hold a state license.
The Nevada State Contractors Board tested and licensed the contractor before they could take this work, and the board keeps a record of them. That license belongs to the contractor, not to this one job, so it covers who is allowed to do the work rather than a sign-off on this particular install.
For the installation itself, the license is what stands behind the person doing the work, but the job still needs a permit from the local building office, and an inspection once the unit is in. That inspection is where someone independent of the contractor looks at what was installed, since most cities and counties in Nevada require it for a new air conditioner.

- What size air conditioner does my house need?
- The right size depends on your home's square footage, insulation, window area, and layout, not on a rule of thumb. An undersized unit will run constantly through July and August and never quite catch up. An oversized one cools the air fast but shuts off before it pulls the moisture out, so the house feels damp. A contractor works this out with a load calculation on the actual house, not a guess based on the old unit's size.
- Should I replace the whole system or just the outdoor unit?
- If the indoor coil and outdoor unit were matched and installed together, replacing only the outdoor unit usually means replacing both anyway. The coil and the compressor are sized to work as a pair, and mixing an old coil with a new compressor can mean the system never reaches its rated efficiency, sometimes voiding the warranty on the new part. A contractor can check the age and condition of the indoor coil and tell you whether it can stay or needs to go with the rest.
- Do HVAC contractors in Fernley need a state license to work on my home?
- Yes. Nevada requires HVAC contractors to hold a state license, issued through the Nevada State Contractors Board. The license is held by the contractor, not issued job by job, so ask to see it before work starts. Installing an air conditioner also typically needs a permit from the local building office and an inspection once the work is done.
