How to choose a home services contractor in Dallas-Fort Worth
You can eliminate most of the risk in this decision before anyone comes to the house. Two of the checks are public records lookups that take about a minute each, and almost nobody runs them.
Short answer
Verify the license first. In Texas, anyone installing or repairing air conditioning and refrigeration systems must hold a license from the Texas Department of Licensing and Regulation, and the state publishes a free lookup. Then confirm insurance, confirm who pulls the permit, and ask what failed and why rather than what it costs.
Step one: verify the license. It takes about a minute.
In Texas, anyone who installs, repairs, or maintains air conditioning and refrigeration systems must hold a license from the Texas Department of Licensing and Regulation, or TDLR. A company also has to employ a licensed air conditioning and refrigeration contractor at each permanent location. The state publishes a free lookup, and almost no homeowner uses it.
Go to the TDLR Search / Verify Licenses tool and search the company name or the license number off their paperwork. Three things to check once you find it:
- Is the status active, rather than expired or on some form of restriction.
- Does the name match the business that is quoting you, not a similarly named entity.
- Is the license held by someone still there. A license attached to a person who left the company is a common and completely invisible gap.
A contractor who cannot or will not give you a license number has answered the question. This is not an awkward thing to ask, and any legitimate company expects it.
Step two: insurance, and what to ask for specifically
Ask for a certificate of insurance, and ask for it to come from the insurer rather than as a photo of a document. You want two things. General liability covers damage to your property. Workers compensation decides who is responsible if someone gets hurt in your home. Texas does not universally require private employers to carry workers compensation, which makes asking more important here, not less.
Step three: permits, and who pulls them
Permits are issued by your city or town, not the state, and the contractor is the one who should be filing. Ask directly whether the work needs a permit and who files it.
The cost of skipping this lands years later. Unpermitted work surfaces during a sale inspection, and resolving it then is the homeowner's problem, sometimes including opening up finished work to get it inspected. Here is where to check in the cities Lantern covers:
Step four: the questions that separate diagnosis from sales
By this point you have filtered out the genuinely risky. What remains is telling apart a contractor who understood your system from one who arrived with a product in mind. Four questions do most of that work.
What failed, and why did it fail?
Anyone can identify a dead capacitor. The second half of the question is the one that matters. A capacitor that failed because it was undersized, because the compressor is drawing hard, or because it is eleven years old are different situations with different right answers. A technician who diagnosed your system can tell you which one you have.
May I see the load calculation?
On any replacement quote. This one question kills a startling share of bad quotes on the spot. A system sized from square footage, or from whatever is already installed, will not have one. The sizing reality check explains what you are looking at when they hand it over.
What is the warranty, on the part and on the labor?
These are two different warranties and they are frequently different lengths. A cheaper quote with ninety days of labor coverage against a more expensive one with two years is not actually the cheaper quote.
What is excluded?
Ask what is not in the number. Ducts, electrical work, permits, disposal of the old equipment, and the thermostat are the usual candidates. Two quotes only become comparable once you know what each leaves out. That accounts for most of why quotes vary as much as they do.
Reading reviews without being fooled by them
Review counts are easy to accumulate and easy to misread. Some things that are more informative than the star average:
- Recency and rhythm. A steady trickle over years reflects an ongoing business. Forty reviews in one week reflects a campaign.
- What the negative ones say. Every real company has some. Complaints about scheduling are normal. Repeated complaints about a job needing to be redone, or about a quote changing after work started, are a pattern.
- Whether reviews describe the work. "Great service, very professional" is compatible with anything. "Found the leak two other companies missed" is a description of something that happened.
A short version you can take to the phone
- Search the company on the TDLR license lookup. Confirm active, confirm the name.
- Ask for a certificate of insurance from the insurer.
- Ask whether the job needs a permit and who files it.
- Ask what failed and why it failed.
- On a replacement, ask to see the Manual J load calculation.
- Get part warranty, labor warranty, and exclusions in writing.
Six questions, and the first three take about two minutes total. They eliminate most of the ways this goes wrong.

Common questions
Do HVAC contractors need a license in Texas?
Yes. The Texas Department of Licensing and Regulation, usually shortened to TDLR, licenses air conditioning and refrigeration contractors. A company has to employ a licensed contractor at each permanent location. You can check any contractor against the state register for free using the TDLR license search, and it takes about a minute.
How do I verify a Texas contractor license?
Use the TDLR "Search / Verify Licenses" tool and search by company name or license number. Confirm the license is active rather than expired, and confirm the name on the license matches the company that is quoting you. A license belonging to a person who no longer works there is a common gap.
Who is responsible for pulling the permit on HVAC or electrical work?
The contractor is, and the permit is issued through your city or town rather than the state. Ask directly whether the work requires a permit and who files it. Skipped permits surface later at resale, when an inspection turns up unpermitted work, and the cost of resolving it then falls on the homeowner.
What questions separate a real diagnosis from a sales call?
Ask what failed, why it failed, and what else the same root cause is likely to affect. A technician who diagnosed the system can answer all three. Ask to see the load calculation on any replacement quote. Ask whether the quoted repair is covered by remaining warranty. A quote that arrives before a diagnosis is a price, not an assessment.
Should I get multiple quotes for HVAC work?
For a replacement, yes, and compare the scope rather than the bottom line. Two quotes for different equipment sizes, different efficiency ratings, or with and without duct work are not comparable numbers. Get the scope in writing on each one, then compare like for like.
