How to Pick a Dallas AC Repair Company That Won't Rip You Off
DFW has hundreds of HVAC companies. Some are honest. Some will quote you $2,500 for a $200 capacitor replacement. Here's how to tell the difference before you let anyone touch your system.
Red Flags That Scream "Walk Away"
"Your whole system needs to be replaced"
Said during a first visit for a minor issue. Some companies send "comfort advisors" (salespeople) instead of technicians. Their job is to sell replacements, not fix problems. A real tech diagnoses the specific issue first.
"We can't give you a price until we open it up"
Legitimate techs can estimate most common repairs before starting. A capacitor is a capacitor. A refrigerant recharge is a refrigerant recharge. Vague pricing means they're sizing up your wallet, not your system.
"We need to do this today — it's dangerous"
Unless there's actual electrical sparking or a gas leak, nothing in AC repair is so urgent it can't wait 24 hours for a second opinion. High-pressure urgency is a sales tactic.
No TDLR license number on the truck or paperwork
Texas requires HVAC contractors to hold a valid TDLR license. No license = no legal protection for you if something goes wrong. Ask for the number and verify it at tdlr.texas.gov.
What Good Dallas AC Companies Do
Give you a written estimate before starting
Diagnostic fee ($75–$180) is fine. But once they know the problem, you should get a written price for the repair before they start working. No surprises.
Show you the failed part
A good tech will show you the blown capacitor, the leaking coil or the burned-out motor. If they can't show you what failed, question whether it actually failed.
Recommend repair when repair makes sense
An honest company will tell you a $200 capacitor replacement on a 10-year-old system is the right call — even though they'd make more money selling you a new system. The companies that always push replacement are optimizing their revenue, not your outcome.
Warranty their work
Minimum 1-year warranty on labor, plus manufacturer warranty on parts. Some companies offer 2–5 year labor warranties on installations. Get it in writing.
Questions to Ask Before Hiring
"What's your TDLR license number?"
Verify at tdlr.texas.gov. No license = unlicensed work = no warranty protection.
"Do you charge a diagnostic fee, and is it waived if I approve the repair?"
Many companies waive the $75–$180 diagnostic if you proceed with their recommended repair.
"Will you give me a written estimate before starting work?"
The only acceptable answer is yes. Walk away from anyone who won't commit to this.
"What's your warranty on parts and labor?"
Parts should carry manufacturer warranty (usually 1–10 years). Labor warranty should be at least 1 year.
"Are you insured?"
General liability and workers' comp. If a tech gets hurt on your property or damages something, their insurance should cover it.
FAQ
What should I look for in a Dallas AC repair company?
Valid TDLR license, BBB accreditation, Google reviews above 4.5 stars, transparent pricing, warranty on parts and labor, willingness to provide written estimates. Avoid companies that pressure same-day replacement decisions.
How many AC repair companies should I get quotes from?
2–3 quotes for repairs over $500 or any replacement. For minor repairs under $300 (capacitors, thermostats), one trusted company is fine. For installations, always get at least 3 — pricing varies $2,000–$4,000 for identical equipment in DFW.
