HVAC keywords by search intent
Emergency and "not working" keywords
"AC not cooling", "furnace not working", "emergency hvac" and "24 hour ac repair" are the highest-intent searches in the trade. People search them minutes before they call.

|---|---|---|
| ac not cooling | Emergency page | Jun–Aug |
| furnace not working | Emergency page | |

| ac repair near me | Google Business Profile | Jun–Aug |

| furnace repair near me | Location page |

How I chose these HVAC keywords
The same seven checks apply to every keyword on this list:
- 1Real demand
at least ~20 searches a month in the US or UK.
- 2Winnable difficulty
realistic for a local HVAC website; harder terms are marked as long-term targets.
- 3A service an HVAC company sells
no HVAC jobs, courses or certifications.
- 4One clear page type
each keyword maps to a specific page.
- 5The results page agrees
Google already shows that type of page for it.
- 6Commercial value
advertisers pay for clicks on it, so buyers search it.
- 7No duplicates
close variants are merged.
Why use these HVAC keywords?
HVAC clicks are expensive on Google Ads (see the ad value column in the CSV), so ranking organically for the right terms is worth real money. But "hvac" and "air conditioning" on their own are national terms you won't win. The keywords here are the ones a local heating and cooling company can rank for, labelled with the exact page they belong on, so you know what to build first.

- US "AC repair" swings about 4×.
It runs 75-79% above average in June-July and falls to about 55% below average in December-January. Cooling pages need to be live and ranking by May.
- US "furnace repair" is much flatter than you'd expect
within about ±10% of average most of the year, with its highest month in August (27% above average). Don't save heating content for winter; keep it live all year.
- US "heat pump"
peaks twice: January and June (19% above average), and dips in October.
- UK "boiler repair"
is a winter search. It's 33-45% above average in November-December, 28% above in January, and 34% below average in June.
- UK "boiler service"
peaks earlier, in September-November (27-29% above average), as people prepare for winter. Promote servicing in late summer.
- UK "air conditioning"
is driven by heatwaves: June runs at 3× the average month, then demand vanishes by October.
UK vs US HVAC keywords
"HVAC" is mainly a US term; UK homeowners rarely search it. A UK heating business should target "boiler", "heating engineer" and "gas engineer" terms, not "HVAC".
| What the customer needs | US search | UK search |
|---|---|---|
| Main heating system | furnace, heat pump | boiler (combi boiler), central heating |
| Who fixes it | HVAC technician, HVAC contractor | gas engineer, Gas Safe engineer, heating engineer |
| Cooling | AC, central air, mini split | air conditioning, air con (mainly summer) |
| Annual check | AC tune up, furnace tune up, HVAC maintenance | boiler service, landlord gas safety certificate |
| Low-carbon heating | heat pump | air source heat pump, heat pump grant / Boiler Upgrade Scheme |
| Brand searches | Carrier, Trane, Lennox | Worcester Bosch, Vaillant |

Common HVAC keyword mistakes
- 1Putting heating and cooling on one page.
They peak in different seasons and are searched separately.
- 2Targeting "HVAC" in the UK.
UK customers search "boiler" and "heating engineer".
- 3Publishing AC content in June.
By then the peak has started; it needs to rank by May.
- 4No emergency page.
"Not working" and "24 hour" searches are your highest-value calls.
- 5Ignoring maintenance keywords.
Service plans are recurring revenue, and the searches come all year.
- 6No prices on installation pages.
Cost searchers move on to a competitor who shows a range.

HVAC keywords FAQ
What are the best keywords for an HVAC website?
Service + urgency + location: "ac repair near me", "furnace repair {city}", "emergency hvac", "boiler repair {town}" (UK). They carry clear buying intent and can be won by local companies.
When should HVAC companies start SEO for summer?
By April. "AC repair" searches climb from April and peak in June-July, so pages need time to rank before the rush.
Do UK heating engineers need different keywords?
Yes. UK searches use "boiler", "combi boiler", "gas engineer", "Gas Safe" and "boiler service". "HVAC" is rarely searched in the UK.
Should I create a page for each brand I install?
Only if people search that brand with a service ("Carrier AC installation", "Worcester Bosch boiler installation") and you're an approved installer. Otherwise mention brands on your installation page.
How do I rank for "HVAC near me"?
Mostly through your Google Business Profile: correct primary category, services listed, steady reviews, and accurate service areas. Your website supports it with clear location information.
How often should I update my HVAC keyword list?
Once a year. I refresh this list every January, before the spring cooling build-up.
