Should I replace the heater now or wait for it to fail?

A heater that is about 15 years old is near the end of its working life, so plan for replacement rather than waiting for a sudden failure. Have a pro inspect it this week to check for leaks, corrosion, and whether repairs would cost more than a new unit. Replacing on your schedule usually avoids a rushed emergency purchase.

What should I check when hiring a pro?

Nevada contractors doing heating or refrigeration work must hold a C-21 license from the Nevada State Contractors Board. Clark County permits are issued only to contractors with an active C-1, C-2, or C-21 license covering the work, plus an active Clark County business license. Ask the pro for proof of licence and insurance before signing.

What does the permit process involve?

Clark County requires a residential pool/spa permit for swimming pools and spas. Applications must include stamped structural plans or manufacturer installation instructions for pre-manufactured units. Pool and spa permits add a flat $110 equipment-and-plumbing fee on top of the estimated permit costs.

What about technician certification?

Technicians who service or repair equipment that could release refrigerant need EPA Section 608 certification. Individual HVAC technicians do not hold state or local licenses, but they must work for a licensed contractor. Ask who will do the work and confirm both credentials.

What to do next

Ask the inspector to note the heater's make, model, and serial number so you can check its age and parts availability.
Verify the contractor's active C-21 license on the Nevada State Contractors Board website before accepting any quote.
Confirm the contractor holds an active Clark County business license, since that is required to pull a Clark County mechanical permit.
Ask the quote to itemize the $200–$500 permit estimate and the $110 Clark County equipment-and-plumbing fee.

Quick answers

How much does a new pool heater cost?

Installation typically runs about $1,800–$6,500 in the Las Vegas area. Permits are estimated at $200–$500 on top of that.

Is it worth repairing an old heater?

For a 15-year-old unit, compare the repair quote against the $1,800–$6,500 replacement range before deciding. A licensed pro can tell you whether the heater's condition justifies repair.

What size heater do I need for my pool?

Sizing depends on your pool's volume and local conditions, so ask the pro to confirm the size in your quote. Clark County permits for pre-manufactured units require manufacturer installation instructions.

Do you recommend gas or electric heaters?

One Las Vegas cost guide says natural-gas heaters raise water about 1–2°F per hour and suit climates with cold nights and short swim seasons. Ask your pro which type fits your pool and usage.
