How we rank companies and build our cost numbers

We do two things: rank the best home-service companies city by city, and research what projects actually cost. Both are done in the open, and every page lists its sources.

How we rank HVAC companies

Our city "best HVAC" lists score each company on five factors, weighted toward what matters for a major installation:

• Warranty coverage — length of the labor warranty on a new install (most local installers cover 1–2 years; the best cover 10).
• Pricing transparency — whether the company gives upfront, written or flat-rate pricing rather than vague "call for a quote."
• Installation & services — breadth and depth of residential AC/heating installation and replacement work.
• Verified rating — public Google and BBB star ratings and review counts.
• Licensing & certifications — a current Texas TACL license and manufacturer/industry certifications.

We list real local competitors by name with their real, sourced numbers — Google ratings, review counts, years in business, and license numbers pulled from each company's public profiles. No company pays for placement, and where a company we'd otherwise feature genuinely leads on a factor, it gets the credit. Ratings drift, so each list shows a "last updated" date and is reviewed monthly.

Cost figures below are assembled separately. Here is that method.

Where the ranges come from

1. Contractor price lists and published rates. Many DFW contractors publish flat-rate menus, starting prices, or financing examples. We collect these across the metro and treat them as the backbone of a range.
2. Permit data. North Texas cities publish permit records that include declared job valuations. Permit valuations skew low, but they're excellent for spotting the floor of a market and for seeing how much work of a given type is actually happening.
3. Manufacturer and distributor pricing. Equipment-heavy projects (water heaters, HVAC, windows) have a knowable hardware cost. Public manufacturer MSRPs and supply-house pricing let us separate equipment from labor in a bid.
4. Published industry data. Trade association cost studies, insurer claim data summaries, and national cost references — used as a cross-check, never as the primary source, because national averages routinely miss DFW by 20% or more in either direction.

When sources disagree, the guide says so. When we only have thin data, the range gets wider and the guide says that too.

Why DFW prices differ from national averages

A national number is wrong here for predictable, physical reasons:

• Slab-on-grade foundations. Almost everything in North Texas is built on a concrete slab over expansive clay. That makes foundation repair its own major industry here, makes under-slab plumbing repairs dramatically more expensive (tunneling vs. crawlspace access), and changes how repipes and leak repairs are bid.
• Expansive clay soil. The clay swells when wet and shrinks in drought. It moves foundations, fences, driveways, and sprinkler lines. Projects that are "set it and forget it" elsewhere carry soil-movement risk pricing here.
• Summer demand spikes. A/C failures cluster in 100°F+ weeks, and roofing demand spikes after every spring hail season. The same job can bid meaningfully higher in July than in February, and our guides flag seasonal swing where it matters.
• Permit and code variation by city. Dallas, Fort Worth, Plano, Frisco, and the dozens of other municipalities each have their own permit fees, inspection regimes, and code amendments. Where a city materially changes the cost, the guide notes it.

Ranges, not quotes

We publish a range because a single number would be a lie. The honest use of this site: get two or three written, itemized bids, then use our range to judge whether they're normal. A bid far below the range is as much of a red flag as one far above it.

Update cadence

• Every guide displays its last updated date — that's the date the numbers were verified, not the date the page was edited.
• Guides are re-checked on a rolling cycle, with high-volatility categories (HVAC, roofing, anything equipment-heavy) reviewed more often than stable ones.
• Corrections from homeowners and contractors are reviewed as they arrive and can trigger an off-cycle update — see about for how to send one.
