Will I get a written estimate before repairs begin?

Yes. Diagnosis, written report, written estimate, your approval, then repair — a fixed order. What a complete estimate contains, and what happens mid-job.

Quick Answer

Yes. Ask Texas Heat & Air to confirm the diagnostic fee when you book. If extra work is discovered mid-job, the process repeats: explanation, updated written quote, your approval. Nothing proceeds on a verbal agreement.

Before you call

Decide now that you will not approve repair work from a verbal quote alone — from any company. If it is not written, it is not an estimate.
Plan to keep your copies. The report and estimate are your reference if questions come up later, your evidence for a second opinion. Your records for any warranty claim.
When the estimate arrives, read it before you sign: scope, parts, warranties, and total. Ask your questions before approval, not after.

How this works

A written estimate protects both sides of the transaction. That is why confident companies insist on it as much as customers do. It names the work, the parts. The price before anyone picks up a tool. So the invoice, when it comes, holds no surprises.

Memory is the enemy it replaces. Two people can remember a verbal price two different ways, and that becomes a dispute. A written price is just a document.

Two documents do two different jobs, and the difference matters. The diagnostic report describes the finding: what failed, what was measured. What else was observed about the system (Q52). The estimate describes the work and its price: the repair proposed, the parts involved, the labor. The total you are being asked to approve. Keeping the two separate is what makes second opinions (Q50) and warranty questions (Q60) possible.

At Texas Heat & Air, the sequence is a standing process, not a favor:

Step	Document	Your control point
Diagnose	Written diagnostic report	You learn the proven cause
Estimate	Written repair estimate	You approve, decline, or compare (Q50)
Repair	Work at the approved price	No verbal add-ons
Discovery mid-job	Updated written quote	You approve again — or not

Jobs do change mid-repair. Older system especially can reveal a second problem once the first is opened up. The process handles that without breaking its own rule. Work stops at the discovery. The technician explains what was found. You receive an updated written quote for the extra work. You approve or decline it.

Verbal add-ons — "while we're in here, for a bit more we could…" — are where misunderstandings and inflated invoices are born. A legitimate discovery survives being written down. Insist that it be.

A complete estimate contains:

Element	Why it matters
The finding, tied to the diagnostic report	Separates "what is wrong" from "what it costs"
The work and parts, in plain terms	You know what you are approving
Parts and labor, separated	You can see how the price is built
The total price	The number the finished invoice should match
The change procedure	Mid-job discoveries get a new written quote, not a verbal add-on
Warranty terms	Workmanship and parts coverage, stated before work begins

When to call a professional

Call a company that will put it in writing. Treat reluctance to write an estimate. From any contractor. As the red flag it is. A company confident in its pricing has never once been harmed by putting it in writing.

What happens next

Keep the report and estimate with your other home records. If a question or a warranty claim comes up months later, those two documents turn an argument into a lookup.
