Full-system HVAC repair covering air conditioning, heating, ventilation, and thermostats. Most repairs cost $150 to $3,500 depending on the component. $79 diagnostic, same-day service, upfront pricing before any work begins.
Unlike AC-only or heating-only services, our technicians evaluate your entire system — from the condenser on your roof to the furnace in your attic, from the ductwork behind your walls to the thermostat on your wall. One visit, one diagnostic, one company that handles everything.
Same-day appointments available across the Las Vegas Valley — heating, cooling, or both.
How much does HVAC repair cost in Las Vegas?
HVAC repair in Las Vegas costs $150 to $3,500 depending on the failed component. Common fixes like capacitors ($150–$350), contactors ($150–$300), and fan motors ($250–$600) fall on the lower end. Major repairs like compressor replacement ($1,500–$3,500) or heat exchanger replacement ($1,500–$3,500) are at the top. Every service starts with a $79 diagnostic with upfront pricing before work begins.
What is the most common HVAC repair?
Capacitor replacement is the most common HVAC repair, responsible for roughly 30% of all service calls. Capacitors store the electrical charge that starts your compressor and fan motors. In Las Vegas, where AC systems run 8 to 12 hours per day during summer, capacitors fail faster than in milder climates due to sustained heat stress. The repair typically costs $150 to $350 and takes 30 to 60 minutes.

Many homeowners search for "AC repair" or "furnace repair" when they actually need HVAC repair. The distinction matters because your heating and cooling systems share critical components. A failing blower motor affects both your air conditioner and your furnace. Leaky ductwork drives up costs in summer and winter. A thermostat malfunction can leave you with no cooling in July or no heat in January.

You are hereCatching problems early prevents expensive breakdowns. If you notice any of these warning signs, schedule a diagnostic before the issue worsens — especially during Las Vegas summers when your system is under maximum stress.
Could be a thermostat issue, low refrigerant, failed compressor, stuck reversing valve, or gas valve malfunction. Check thermostat settings first.
A clogged filter, failing blower motor, ductwork leak, or frozen coil can all reduce airflow. Some rooms hot while others stay cold.
Grinding means a motor bearing is failing. Banging indicates a loose or broken component. Squealing often points to a belt issue or blower problem.
Causes include an oversized system, dirty filter, low refrigerant, faulty flame sensor, or overheating components. Short cycling increases wear and energy bills.
Musty smell means mold in ducts or on the coil. Burning suggests an electrical issue. A rotten egg smell near a gas furnace means a potential gas leak — leave immediately.
Ice on refrigerant lines indicates restricted airflow or low refrigerant. Water pooling means a clogged condensate drain or cracked pan.
Dead batteries, faulty wiring, or a failing thermostat sensor. If the display is blank or the system ignores setpoints, diagnosis is needed.
A system losing efficiency due to worn components, refrigerant leaks, or dirty coils runs harder and longer, driving up costs 20–40%.
From your first call to verified system operation, here is exactly what to expect.
Call (702) 567-0707 or book online. We offer same-day service 7 days a week, with emergency appointments available for no-cooling and no-heating situations.
Our licensed technician inspects your entire HVAC system — cooling, heating, ductwork, thermostat, and airflow — not just the symptom you reported.
💡 Pro Tip: A full-system diagnostic catches underlying problems that a component-only check would miss, saving you from repeat service calls.
We explain exactly what is wrong, what parts are needed, and present the total cost before any work begins. No surprises, no pressure.
💡 Pro Tip: If the repair cost approaches replacement territory, we provide a repair vs. replace comparison so you can make an informed decision.
Work is completed with manufacturer-specified parts by NATE-certified technicians and backed by our workmanship warranty.
After the repair, we run the entire system through heating and cooling cycles to confirm every component is operating correctly before we leave.
Should I repair or replace my HVAC system?
Repair makes sense when your system is under 10 years old, the repair costs less than 50% of a new system, and it is your first or second major repair. Replace makes sense when the system is 15 or more years old, uses R-22 refrigerant, has had 3 or more repairs in the past two years, or has a cracked heat exchanger. Our technicians provide honest guidance during every diagnostic — we never push unnecessary replacements.
| Feature | Repair | Replace |
|---|---|---|
| Upfront cost | $150 – $3,500 | $11,000 – $27,000 |
| Best for | Isolated failures, systems under 10 years | Systems 15+ years, R-22, repeated failures |
| Speed to comfort | ||
| Energy savings | Limited (same efficiency) | High (new SEER2 standards) |
| Long-term reliability | Depends on system age | Full manufacturer warranty |
| Monthly energy cost | No change | 15–40% lower |
| Refrigerant concerns | R-22 if pre-2010 | Modern R-410A or R-454B |
Our Recommendation: If your system is under 10 years old and the repair is under $1,500, repair is almost always the right call. For systems 15+ years old with major component failures, replacement delivers better value through improved efficiency and a full warranty.
