Conditions that change the job here
- Extreme summer heat (110°F - 118°F+ ambient) causes intense thermal stress on outdoor AC compressors and shortens capacitor/fan motor lifespan.
- Extremely hard water (25+ grains per gallon from Lake Mead) causes severe mineral scaling, making water softeners and tankless water heater flushing essential.
- Caliche soil (dense hardpan layer of calcium carbonate) requires heavy jackhammering or excavator trenching for plumbing and underground electric.
- Desert high UV index accelerates degradation of outdoor plastic piping, conduit, and exposed roof materials.
- High popularity of residential solar PV and battery storage systems (NV Energy interconnect rules) drives high 200A/400A panel upgrade volume.

Verify before you hire in Nevada
Check the licence with the Nevada board
EPA Section 608 is required nationwide to handle refrigerant. Many states add a separate HVAC contractor or mechanical license. Search the number in the state's public lookup, confirm it is active, and confirm the classification covers your job rather than something adjacent to it.
Have the insurer send the certificate
Ask for general liability and workers' compensation to be sent to you directly by the insurance agent. A PDF forwarded by the contractor proves the document existed once, not that the policy is current.
Get the scope in writing, with exclusions
What is included matters less than what is excluded. Permits, disposal, patching, and code upgrades triggered by the work are the four line items that most often turn into change orders.
Confirm who pulls the permit
Permit thresholds are municipal in Nevada. The licence holder should pull it. If you are asked to pull it as a homeowner on licensed work, you are absorbing their liability.
Never pay the full amount up front
A deposit for materials on a large job is normal. Paying in full before work begins is not, and several states cap what a contractor may take as a deposit.
Work out the problem before you call
- CoolingAir Conditioner Not CoolingWork through the causes of an air conditioner that runs but does not cool, ordered from most to least likely.
- HeatingFurnace Not HeatingDiagnose a gas furnace that will not fire, short cycles, or blows cold air, starting with what you can safely check.
- HeatingFurnace Short CyclingA furnace that turns on and off every few minutes instead of running a full heating cycle — what causes it and what each fix costs.
- CoolingAC Freezing UpIce on your AC lines or evaporator coil — why it happens, what to do right now, and what the underlying repair costs.
- CoolingAC Blowing Warm AirYour air conditioner runs but the air from the vents is warm — work through the causes from cheapest to most expensive.
- HeatingFurnace Blowing Cold AirThe furnace runs but the air from your vents is cold or lukewarm — diagnose the cause before calling for an expensive repair.
- HeatingFurnace Blower Won't Stop RunningThe furnace blower runs continuously even when heating or cooling is not called — find out why and what it costs to fix.
- HVACThermostat Screen BlankA blank thermostat display usually means no power to the device — work through the causes before assuming the whole system has failed.
- CoolingAC Leaking WaterWater under the indoor air handler or furnace — usually a clogged condensate drain, not refrigerant — can damage ceilings if the pan overflows.
- CoolingAC Smells MustyMusty odor when AC runs points to mold on the evaporator coil, dirty drain pan, or duct moisture — not normal and worth cleaning before peak season.
- CoolingAC Making Screeching NoiseHigh-pitched screeching from the outdoor unit or air handler often means a failing belt, bearing, or compressor — shut down if grinding accompanies the noise.
- CoolingOutdoor AC Unit Not RunningIndoor fan runs but the condenser stays silent — check disconnect, breaker, thermostat call, and contactor before assuming compressor failure.
- CoolingAC Tripping BreakerA breaker that trips when AC starts or runs points to locked compressor, bad capacitor, shorted wire, or dirty coil raising amp draw.
- CoolingAC Running ConstantlyAC that never cycles off may be undersized for the heat load, low on refrigerant, fighting poor insulation, or set to fan On instead of Auto.
- CoolingIce on Refrigerant LineFrost or ice on the suction line or outdoor unit means restricted airflow or low charge — turn cooling off and thaw before serious compressor damage.
- CoolingMini Split Not CoolingA ductless head that blows warm air while others cool — filter, refrigerant leak, mode setting, or communication fault between indoor and outdoor units.
- HeatingFurnace Smells Like GasRotten-egg odor near a gas furnace is an emergency — leave, do not switch lights, and call the gas utility from outside; brief smell on startup may be normal if it dissipates.
- HeatingFurnace Pilot Won't LightOlder standing-pilot furnaces need gas flow, thermocouple signal, and clean pilot orifice — electronic ignition systems differ; know your type before troubleshooting.
- HeatingFurnace Making a BoomA loud bang at furnace startup is delayed ignition — gas builds before flame lights — and can crack heat exchangers or harm occupants over time.
- HeatingHeat Pump Blowing ColdHeat pumps blow cooler-than-furnace air normally — but icy cold air in heat mode means defrost failure, reversing valve stuck, or auxiliary heat not engaging.
- HeatingUneven Heating Between RoomsSome rooms cold while others roast — duct balance, insulation, solar gain, or equipment sizing — not always a failing furnace.
- HVACVents Blowing Weak AirLow airflow at registers reduces heating and cooling — filter, blower, duct leaks, or crushed flex are the usual suspects before replacing equipment.
- HVACThermostat Won't Change TemperatureSetpoint changes but nothing happens — dead batteries, locked schedule, wiring, or equipment lockout — verify the display and whether heat or cool actually calls.
- HVACHigh Humidity IndoorsSticky indoor air above 55% RH — oversized AC, poor ventilation, basement moisture, or short cycles — risks mold and discomfort even when temperature feels OK.
- SafetyCarbon Monoxide Alarm Going OffCO alarms signal incomplete combustion — evacuate and call 911 or the fire department from outside.
- SafetyRadon Test Came Back HighElevated radon needs mitigation — sealing alone rarely fixes; active depressurization is standard.
