HVAC Websites in Texas: 438 Sites Audited

Why It Matters

Homeowners searching for HVAC service at 11 PM — when their AC just failed — can't call during business hours. Without an online scheduling option, those emergency leads go to whichever competitor lets them book immediately. Studies show that businesses with online booking convert 2-3x more after-hours visitors.

What Top-Scoring Sites Do

The highest-scoring HVAC websites in Texas embed booking widgets from platforms like Housecall Pro, ServiceTitan, or Calendly directly on their homepage. Visitors can select a time slot without picking up the phone.

The Bottom Line

In Texas, 83% of HVAC websites (357 companies) have no online scheduling. Every one of them is losing after-hours leads to competitors who do.

Why It Matters

When a site loads over HTTP instead of HTTPS, browsers display a 'Not Secure' warning in the address bar. For a homeowner about to submit their address and phone number to schedule an HVAC service call, that warning kills trust instantly. Google also uses HTTPS as a ranking signal.

What Top-Scoring Sites Do

Top-performing HVAC websites in Texas have SSL certificates installed and properly redirect all HTTP traffic to HTTPS. This is a one-time server configuration that eliminates the warning permanently.

The Bottom Line

78% of HVAC sites in Texas (337 businesses) either lack an SSL certificate or don't redirect HTTP to HTTPS. Visitors see 'Not Secure' before they even read the homepage.

Why It Matters

Displaying a license number is one of the simplest trust signals a contractor can show. Homeowners checking multiple HVAC companies will choose the one that visibly proves they're licensed. In many states, displaying your license number on your website is a legal requirement.

What Top-Scoring Sites Do

Top-scoring sites in Texas display their license number in the footer, on their About page, and often in the hero section. Some link directly to the state licensing board verification page.

The Bottom Line

In Texas, 72% of HVAC sites (310 businesses) don't show their license number anywhere on their website. It takes five minutes to add — and it immediately increases trust.

Data Collection

We identify HVAC businesses through Google Maps, then visit each company's website using a headless browser that simulates a real visitor. Every site is checked for speed, security, lead capture, trust signals, SEO fundamentals, mobile experience, and content depth.

What We Measure

• Page load speed (headless browser measurement)
• SSL security and HTTPS redirect
• Lead capture: online booking, contact forms, click-to-call, after-hours capture
• Trust signals: reviews displayed, license numbers, industry certifications
• SEO fundamentals: meta tags, structured data, XML sitemap
• Mobile experience: responsive design, sticky contact options
• Content depth: service area pages, about page, blog

Scoring

Each website receives an HVAC Website Index score from 0 to 100 based on six weighted categories: Speed (20%), Trust (20%), Lead Capture (25%), SEO (15%), Content (10%), and Mobile (10%).

Sample Size

This report is based on 438 HVAC websites, of which 430 received in-depth audits with 100+ data points each.

Limitations

Our audits measure website quality, not business quality. A company with a low-scoring website may still provide excellent HVAC service. Scores reflect online presence only.
