If a technician punctured your AC evaporator coil during service, that damage is their responsibility. The fair remedy is a free, brand-new matching coil installed at no cost to you, not a $5,300 to $6,500 push to replace your whole system. Take the free coil in writing, and treat any full-replacement offer as a separate decision.
Who is responsible when a technician punctures my AC coil?
The company whose technician caused the damage is responsible for fixing it. If a tech puncturing your evaporator coil turned a routine visit into a broken system, that is a liability issue, not a normal repair you should fund. A free replacement coil is the honest, reasonable remedy. Offering it while also steering you toward a $5,000-plus new system is a red flag. You are entitled to be put back in the position you were in before the mistake. Get the free coil, its warranty, and confirmation that all related labor and refrigerant recovery are covered in writing. Reputable HVAC companies in Seguin and across Central Texas own their errors, document them clearly, and do not use a mistake as a sales opportunity to upsell equipment you did not need before the visit.
Is $5,300 to $6,500 reasonable to replace an AC system?
That range can be legitimate for a full AC system replacement in Central Texas, especially with higher-efficiency equipment, larger tonnage, or duct upgrades. Prices vary by home, so always get an exact written quote. The problem here is not the number, it is the framing. You did not need a new system before the technician punctured your coil. So the real question is whether you need one at all. If the only issue is the damaged coil, a new matching coil is the fix, and the company caused it, so it should be free. Consider a full replacement only if your system was already old, inefficient, or on refrigerant that is being phased out. Even then, decide on your own timeline with a clear, separate quote, not under pressure created by someone else’s mistake.
New coil versus new system - which do I actually need?
Match the fix to the actual failure. A punctured coil, on its own, calls for one thing: a new evaporator coil that matches your existing condenser and blower. If the rest of your system is sound and reasonably young, replacing just the coil restores full cooling. A whole-system replacement makes sense only when multiple factors line up, such as an aging condenser, repeated failures, poor efficiency, or an outdated refrigerant. In our hot, humid Central Texas climate, systems run hard for eight to nine months a year, so age matters. But none of that changes who pays for the coil the technician broke. Ask the company to clearly separate two things in writing: the free coil that fixes their damage, and any optional replacement quote you can evaluate independently. Bundling them is how a fair remedy quietly becomes an expensive upsell.
What should I get in writing before agreeing to anything?
Documentation protects you. Before you sign, get a written statement acknowledging the technician punctured the coil and confirming the replacement coil is provided at no charge. Ask for the specific part number so you can verify it is new and correctly matched, not salvaged. Confirm the manufacturer warranty on the new coil, typically five to ten years on parts. Make sure all labor, refrigerant recovery, and recharge tied to their mistake are covered with no hidden fees. If they hand you a full-system quote, keep it as a separate document you are free to accept or decline later. If anything is vague, verbal, or pressured, pause. A licensed, honest company will put its commitments on paper without hesitation, because clear documentation is exactly how quality work and upfront pricing should look.
Should I get a second opinion from another HVAC company?
Yes, especially if trust is gone. You are never obligated to let the company that damaged your coil control the outcome. A second opinion from another licensed HVAC company in Seguin, New Braunfels, or San Antonio can confirm whether you truly need a coil or a full system, and what fair pricing looks like for your equipment. Because refrigerant handling is EPA-regulated and coil work involves sealed-system repairs, this is not a DIY job, so choose a licensed pro either way. Bring your documentation and the original company’s quotes. A trustworthy tech will tell you plainly if a new coil is all you need. If two independent licensed companies agree the fix is just the coil, you have strong footing to insist the original company cover it free, exactly as they offered.
