Fallon homes built before the 1990s often have undersized or poorly sealed duct runs that leak 20-30 percent of conditioned air into attics. When installing a new central system we first pressure-test existing ducts, then add mastic sealing and R-8 insulation where runs travel through unconditioned spaces. High desert temperature swings of 40 degrees between day and night mean the thermostat must be located away from south-facing windows and the outdoor unit needs at least 18 inches of clearance from the prevailing west wind to avoid dust loading the coils.
Churchill County building requirements call for a manual J load calculation on every new installation; we perform this on-site rather than using rule-of-thumb sizing. Because summer highs regularly exceed 95 degrees and winter lows drop below 20, many Fallon properties benefit from a two-stage compressor paired with a variable-speed blower so the system can run at low capacity during shoulder seasons without short-cycling. We also verify that the condensate line drains properly into the home’s existing plumbing to prevent freeze-ups during cold nights.
Naval Air Station Fallon’s flight pattern creates occasional low-frequency vibration that can loosen poorly secured line sets. Our crews use vibration-isolating hangers and route refrigerant lines through exterior walls with proper flashing to keep dust out of the wall cavity. After startup we record supply and return temperatures at each register and leave the homeowner with a written commissioning report that shows static pressure and amperage draw under local design conditions.
Technician insight
In Fallon the thing that catches most people out with Central AC Installation is how much dust from the high desert loads new coils within the first season if the outdoor unit sits on the west side without a windbreak; we always add a simple screen and raise the pad so prevailing winds do not drive fine silt straight into the fins.
Older Ranch Home Near Churchill County Museum
The 1978 single-story house had a 3-ton unit that could not keep up once afternoon temperatures hit 98 degrees. We found collapsed flex duct in the attic and an undersized return. After running a Manual J we installed a 3.5-ton two-stage system, sealed and insulated the ducts, and added a larger return grille. Supply temperatures now average 14 degrees below return even during peak heat.

How it works
- 1
Site Assessment
We measure every room, inspect ductwork, and run a Manual J calculation while noting sun exposure and wind patterns typical around Naval Air Station Fallon.
- 2
Equipment Selection
We recommend two-stage or variable-speed models that match the calculated load and local temperature swings between 95-degree days and 20-degree nights.
- 3
Duct And Electrical Prep
Existing ducts are sealed and insulated; new line sets and circuits are run with proper supports and flashing to resist desert dust.
- 4
Installation And Commissioning
Unit is set, refrigerant charged, static pressure verified, and a written report of supply temperatures and amperage is left with the homeowner.
Pricing
Most Fallon central AC installations fall between $4,200 and $7,800 depending on tonnage, duct modifications, and whether electrical service must be upgraded.
