Not sure whether to fix your current system or invest in a new one? We help Las Vegas homeowners make the smartest decision for their comfort and budget.
Repair vs Replace: Side-by-Side Comparison
Here's what each option looks like for Las Vegas homeowners dealing with AC problems during our extreme summer heat.
Repair Your AC
- Lower upfront cost ($150–$1,200)
- Quick fix — often same-day
- No guarantee against future breakdowns
- Older systems lose efficiency over time
- R-22 refrigerant costs rising sharply
- No new warranty coverage
- Higher monthly energy bills continue
Replace Your AC
- New system from $7,900 (financing available)
- Full manufacturer warranty (5–10 years)
- Up to 40% lower energy bills
- Modern R-410A or R-454B refrigerant
- Reliable cooling for 15–20 years
- Better humidity control and air quality
- Increased home value
Cost Analysis: Repair vs Replace Over 5 Years
When you factor in repair frequency, energy costs, and system reliability, replacement often costs less over time — especially in Las Vegas where AC runs 7+ months per year.
| Cost Factor | Keep & Repair | Replace Now |
|---|---|---|
| Initial Cost | $500–$1,200/repair | $7,900–$14,500 |
| Avg. Repairs (5 yrs) | 3–5 repairs ($2,500–$5,000) | $0 (under warranty) |
| Monthly Energy (summer) | $350–$500+ | $200–$320 |
| 5-Year Energy Savings | — | $3,600–$7,200 |
| 5-Year Total Cost | $15,000–$22,000+ | $10,900–$17,500 |
| Risk of Breakdown | Increasing each year | Minimal (new system) |
*Estimates based on typical Las Vegas homes (1,500–2,500 sq ft) with systems over 10 years old. Actual costs vary by system size and condition.
Key Decision Factors
Consider these factors when deciding whether to repair or replace your AC system in the Las Vegas climate.
System Age
AC units in Las Vegas typically last 10–15 years due to extreme heat stress. If your system is over 10 years old, replacement is usually the better investment. Under 7 years? Repair likely makes sense.
Repair Cost Rule
Use the "50% rule": if a repair costs more than 50% of a new system, replace it. For Las Vegas, we lower that to 30–40% because of how hard our systems work.
Refrigerant Type
If your system uses R-22 (Freon), replacement is the only long-term option. R-22 has been phased out, and recharge costs have skyrocketed to $150–$300 per pound.
Energy Bills
Older systems run at 10–13 SEER. New systems start at 15 SEER (16+ SEER2). In Las Vegas, where AC accounts for 50–70% of summer electric bills, the savings are substantial.
Repair Frequency
If you've called for repairs more than twice in the past two years, your system is telling you something. Frequent breakdowns signal compounding failures that get more expensive each time.
Comfort Level
Hot spots, humidity problems, or rooms that never cool properly often indicate a system that's either failing or was improperly sized from the start. A new system solves both issues.
When Repair Makes Sense
Repair is the right call in certain situations. Here's when we recommend fixing your existing system.
- Your system is under 7 years old and still under warranty
- The repair is minor (capacitor, contactor, thermostat) and costs under $500
- This is the first major repair and the system has been well-maintained
- Your system uses modern refrigerant (R-410A or R-454B)
- Energy bills have remained stable and consistent
- You plan to sell the home within 1–2 years
When Replacement Is the Smarter Investment
In the Las Vegas climate, replacing sooner often saves more than repairing repeatedly.
- System is over 10 years old (average Las Vegas AC lifespan)
- Repair cost exceeds $1,000 or 30% of a new system price
- Multiple breakdowns in the past 2 years
- System uses phased-out R-22 refrigerant
- Current SEER rating is below 14 (modern minimum is 15 SEER / 14.3 SEER2)
- Monthly electric bills are $400+ during summer
- Home has uneven cooling, humidity issues, or excessive dust
