Your system works every month of the year here
There is no season off in Clark County. Summer afternoons average 98°F from May through October, and your air conditioner runs that entire stretch to keep up. Then winter nights average 37°F from November through April, and the furnace takes over. Twelve months a year, one system or the other is working.
Most homes here heat with gas, and a new furnace has to handle nights averaging 37°F without struggling. The air conditioner carries the harder load, holding a house steady against 98°F afternoons for six months straight. A system installed for this place has to be built for both jobs, not just the one you're thinking about today.

Nevada requires HVAC contractors to hold a state license.
The Nevada State Contractors Board tests contractors before they're licensed and keeps a record of who holds one. That license belongs to the contractor, not to any single job, so the same license that covers your neighbor's install covers yours.
For a job like this, replacing a furnace and putting in an air conditioner or heat pump, the local building office typically requires a permit, plus an inspection once the work is done. That inspection is what checks the installation itself, separate from whether the contractor is licensed to do the work.

- When should I replace my HVAC system?
- Replace it when repairs start coming often, or when the system is old enough that another repair is throwing money at something you're about to replace anyway. Age matters here more than in mild climates. Your air conditioner runs hard from May through October with afternoons near 98°F, and your furnace has to work on nights that drop to 37°F from December through February, so the system gets used twelve months a year with no real break. If a contractor tells you the compressor or the heat exchanger is failing, that's usually the point where replacement makes more sense than another repair.
- Should I replace my furnace and air conditioner at the same time?
- If they're close in age, yes, it usually makes sense to do both together. A furnace and air conditioner installed at the same time are matched to work as one system, and doing them separately means pairing new equipment with an old blower or old coil that wasn't sized for it. This matters more here because both sides of the system get real work every year, six months of heat and six months of cooling, so neither one is sitting idle waiting to fail. A contractor can look at the age and condition of each unit and tell you whether replacing both now is worth it or whether the other one has good years left.
- What happens during an HVAC installation?
- A contractor removes the old furnace and air conditioner, or heat pump, and sets the new equipment in place, then connects it to your ductwork, gas line or electrical circuit, and the refrigerant lines. After that they test the system, checking airflow, refrigerant charge, and that the thermostat is talking to the equipment correctly. In most cities and counties around Las Vegas this work needs a permit from the local building office, and an inspector checks the job once it's done. That inspection is there to confirm the install was done to code, which matters for both safety and for warranty coverage down the line.
