Eliminate Render-Blocking CSS
High Impact+15 points estimated
Why It Matters
Render-blocking stylesheets delay First Contentful Paint by 900ms and impact LCP timing.
How to Fix
Inline critical above-the-fold CSS directly in the HTML head. Use WP Rocket's CSS optimization to defer non-critical stylesheets like Dashicons (36KB) and third-party CSS. Remove unused CSS rules, especially from ServiceTitan (174KB) and Google Maps (49KB).

AI Performance Analysis
This WordPress site has poor performance with a score of 68/100, and users experience extremely slow interactivity with a 22.5-second Time to Interactive. The biggest problem is excessive JavaScript execution taking 1.4 seconds, which blocks the main thread and prevents users from interacting with the page effectively. The site is loading over 1MB of unused JavaScript and CSS, particularly from third-party services like ServiceTitan scheduler and Google Maps, which could be deferred or removed entirely. Reducing JavaScript payloads, optimizing images (which could save 217KB), and implementing proper caching could potentially improve the performance score by 25+ points and dramatically reduce loading times.
Other Optimization Recommendations
Reduce JavaScript Execution Time
High Impact+18 points estimatedWhy It Matters:
JavaScript execution takes 1.4 seconds and blocks the main thread for 600ms, severely impacting TBT and user interactivity.
How to Fix:
Remove or defer unused JavaScript from ServiceTitan scheduler (182KB unused) and Formidable Pro (102KB unused). Use WP Asset CleanUp to conditionally load scripts only where needed. Move Google Maps and tracking scripts to load after page interactive using defer or async attributes.
Optimize Image Delivery
Medium Impact+8 points estimatedWhy It Matters:
Oversized images waste 217KB of bandwidth and slow down perceived performance.
How to Fix:
Resize the HVAC upgrade image to match its displayed dimensions (511x681 instead of 1000x1333). Convert Google profile images to WebP format and implement responsive image sizes. Use WordPress's srcset attribute or a plugin like Smush to automatically serve appropriately sized images.
