Get a Second Opinion on Your AC Before You Replace It
Plenty of LA homeowners have been told they need a $12,000 system when the real problem was a $200 capacitor or a clogged drain. A second opinion costs far less than an unnecessary replacement, and if you really do need a new system, you will know the quote is fair.

The short answer
When Should I Get a Second Opinion?
Any time you are told to replace a system that was working fine until recently, or you are handed a quote over about $1,500 without a clear explanation of what failed. Also get one if:
- You were told the system “needs refrigerant” but nobody looked for the leak
- A routine tune-up ended with a replacement pitch
- The technician could not show you the failed part or a reading that proves it
- The quote says “condemned” or “unsafe” without explaining why
- The price was only good “if you sign today”
- The quote does not list model numbers, tonnage or a permit
Real examples
What Second Opinions Often Find
| What you were told | What it often turns out to be | Typical LA repair cost (2026) |
|---|---|---|
| “Your compressor is dead, you need a new system” | A failed capacitor that stopped the compressor from starting | $150 to $400 |
| “The system is shot, it won’t turn on” | A failed contactor, blown fuse or a float switch tripped by a clogged drain | $100 to $350 |
| “Water damage means it has to be replaced” | A clogged condensate drain line or cracked drain pan | $100 to $300 |
| “It is low on refrigerant every year, time to replace” | A leak at a fitting or valve that can be found and repaired | $400 to $1,500+ |
| “Your rooms are hot because the AC is too small” | Leaky or crushed attic ducts | Varies; see ductwork |
How we decide
How to Tell if Replacement Really Makes Sense
Use the $5,000 rule: multiply the system’s age by the repair cost. Over $5,000 usually points to replacement. Under $5,000 usually means repair. A 15-year-old system with a $300 capacitor (4,500) should be repaired. The same system with a $2,500 compressor (37,500) is a replacement candidate.
Other things that genuinely justify replacement:
- A failed compressor or evaporator coil on a system over 12 to 15 years old
- An R-22 system with a refrigerant leak, since R-22 is no longer produced
- A cracked furnace heat exchanger, which is a carbon monoxide risk
- Repeated major repairs within a couple of years
What does not justify replacement on its own: the R-410A phase-out. New R-410A systems can no longer be made, but existing ones can still be repaired and recharged legally.
If you do replace
Checking a Replacement Quote
If replacement is the right answer, a second opinion can still save money. In Los Angeles in 2026, a central AC on existing ducts typically costs about $5,500 to $12,000 installed, and a ducted heat pump about $9,000 to $17,000. Compare quotes on:
- Matched model numbers and an AHRI certificate
- A load calculation, not “same size as before”
- LADBS permit and HERS testing included
- Whether LADWP rebates apply, which can be $1,000 or more per ton for heat pumps
- Warranty terms in writing

Process
How a Second Opinion Works
- Send the quote and photos by text, or call (213) 659-0061.
- We review it and tell you which parts look right and what questions to ask.
- If you want certainty, a technician inspects the system in person and tests the part in question.
- You get a plain-English answer: repair, replace, or get more information, with the numbers for both options.
FAQ
Frequently Asked Questions
Is it worth getting a second opinion on an HVAC replacement?
Yes. A new system in LA typically costs $5,500 to $17,000. A second opinion can catch a misdiagnosis, like a failed capacitor mistaken for a dead compressor, and confirms the price is fair when replacement is genuinely needed.
How much does an HVAC second opinion cost?
Reviewing a written quote and photos is free. An in-person inspection is billed as a standard diagnostic visit, which typically runs $70 to $250 in Los Angeles.
How do I know if my compressor is really bad?
A technician should be able to show you readings, such as winding resistance, amp draw or a shorted-to-ground test, not just say it is bad. A failed capacitor can make a healthy compressor look dead.
Should I replace my AC because of the R-410A phase-out?
Not on its own. Only new R-410A equipment manufacture ended on January 1, 2025. Existing systems can still be repaired and recharged legally.
What is the $5,000 rule?
Multiply the age of your system by the repair cost. Over $5,000 usually means replacement makes more sense; under $5,000 usually means repair.
