93.7%
of HVAC contractor websites fail Core Web Vitals on mobile
HVAC contractors spend heavily on Google Ads during peak season — summer AC calls, winter furnace repairs, shoulder-season tune-up specials. But when a homeowner clicks that ad and lands on a slow website, the lead is gone before they ever fill out a form.
Structure1 Digital measured 80,184 HVAC contractor websites across the United States using Google PageSpeed Insights. The results reveal a sector-wide performance crisis — one that costs HVAC companies leads and ad dollars every single day.
The core finding: 93.7% of HVAC websites fail Core Web Vitals on mobile. That means only about 1 in 14HVAC sites passes Google's performance benchmarks for user experience. Here's the full data.
Key Findings: HVAC Website Performance
93.7% fail Core Web Vitals on mobile
Google's Core Web Vitals measure loading speed (LCP), interactivity (INP), and visual stability (CLS). Failing any one metric constitutes a failing grade. Among HVAC contractor websites, 93.7% fail at least one metric on mobile — meaning the majority of HVAC sites are delivering a subpar experience to homeowners searching on phones.
Average mobile PageSpeed score: 40.6/100
Google considers a score of 90+ as "Good" and 50–89 as "Needs Improvement." The average HVAC contractor site scores 40.6/100 on mobile — squarely in the "Needs Improvement" or "Poor" range. For a homeowner on a 4G phone, this translates to a 4–8 second wait before the page is usable.
Desktop performs better at 50.1/100, but mobile is what drives leads
Most HVAC searches happen on mobile — someone's AC breaks down mid-summer and they search from their phone. Google also uses mobile performance to determine ad Quality Score and organic rankings. A fast desktop score doesn't help when mobile fails.
Slow sites burn ad budget silently
Google Ads penalizes slow landing pages through lower Quality Scores, which forces HVAC companies to bid higher to maintain ad position. A site scoring below 50 on mobile can cost 30–50% more per click than a competitor with a fast site — on exactly the same keyword.
Performance gaps vary significantly by market
While the national average paints a bleak picture, individual cities show significant variance. Some HVAC markets have surprisingly competitive web performance, while others are uniformly slow — creating an opportunity for any company willing to invest in a fast site.
Why HVAC Website Speed Determines Whether You Get the Lead
HVAC is an intent-driven, urgency-driven category. When a homeowner's AC fails in July, they are not comparison shopping — they are calling the first company with a fast, trustworthy website. A slow page during that moment costs a job worth $3,000–$10,000.
The lead-gen math for HVAC:
- • 53% of mobile users abandon a site that takes more than 3 seconds to load
- • A 1-second delay in load time reduces conversions by 7% on average
- • Google Ads Quality Score drops significantly for landing pages scoring below 50 on mobile
- • Low Quality Score = higher cost per click on "AC repair near me", "furnace replacement", and similar high-value HVAC terms
For HVAC companies running $5,000–$30,000/month in Google Ads, landing page performance isn't a technical concern — it's a budget concern. A fast website lowers cost per lead. A slow one inflates it.
