Furnace replacement in Henderson, NV
A furnace here works a short season, so it can last a long time. When it does give out, the choice ties into the air conditioner sharing its cabinet.
When replacement comes up
A cracked heat exchanger found during a safety check, a failed control board on an old unit, or repairs that come back every winter are the usual starting points. In most local homes the furnace also houses the blower for summer cooling and sits under the AC coil, so its condition affects both seasons.
Points to settle with the contractor
- 01
Heating capacity
Sized to the house, not copied from the old label. Mild winters often call for less than the original.
- 02
Blower type
A variable-speed blower serves the air conditioner all summer, which can matter more here than the burner.
- 03
Match with the AC coil
The cabinet width, airflow and coil must fit together, or the cooling side suffers.
- 04
Venting
High-efficiency condensing furnaces vent through plastic pipe and need a drain; standard models use metal flue.
- 05
Gas connector
Southwest Gas advises having older uncoated brass connectors inspected and replaced by a qualified contractor.
The gas line on your side of the meter
Southwest Gas says customers own and must maintain all gas piping from the meter to their appliances (Southwest Gas safety). A furnace swap is a good moment to have the contractor look at the connector and shutoff valve at the unit.
Permits
Henderson handles permits through its Building and Fire Safety department (city page). In unincorporated Clark County the simple online permit list has separate furnace replacement categories for smaller and larger furnaces, and a combined A/C and furnace category, each limited to one appliance per permit (Clark County simple permits). The contractor files the right one.
Questions
Should I replace the AC at the same time?
If the air conditioner is also aging, one project keeps the equipment matched and the permits together. If it is fairly new, the furnace can be chosen to fit it.
Can a furnace move from the attic to the garage?
Sometimes, with duct and gas line changes. That is a design change the contractor needs to plan and permit.
