Six criteria, weighted. The full method, including what would move a company up or down, is on how we rank.
Do they work on HVAC, or on everything?
Count the industries the company lists in its own navigation. 5 means HVAC or the trades and nothing else. 1 means a general agency with one HVAC landing page.
Can you find out how to leave before you sign?
Four things: the initial term, the notice period, who owns the site and the data and the ad accounts, and any territory clause. Scored on how many are documented and how the documented ones read. A term nobody publishes scores as not published, never as a bad term.
Can they show you a named HVAC client?
Count the case studies that name the business, name the trade, and give a number over a stated period. A running total on a homepage, however many hundreds of contractors it claims, counts for nothing here, because you cannot ring up a total.
Do they say what is in the monthly report?
Whether the company names the metrics its report carries, says how often it lands, and says whether a person walks you through it.
Do you know who will actually do the work?
Whether people are named with roles, whether the person doing the SEO is named rather than only the salesperson, and whether the company says the work is done in-house.
How long have they been trading?
The founding year the company publishes, checked against the oldest dated thing we could find from them. Weighted lightest of the six: a 2004 founding date says nothing about who is on your account in 2026.
It merged with RYNO Strategic Solutions on 1 October 2024 and the combined business trades under the RYNO name, which Blue Corona's own site says on its partners page. The old domain still ranks first for "HVAC SEO company" and still collects enquiries. If you fill that form in, you are talking to RYNO, whose parent is EverService Holdings.
Type the old address in and you land on KickCharge's site. Plenty of "best HVAC agency" lists published this year still rank the two of them separately, which tells you how carefully those lists were put together.
Consolidation matters more here than it looks. When an agency is bought, the people who did your work often leave within a year, and the reporting platform you were sold gets replaced by the parent's. Ask who owns the company before you ask what they charge. The ownership trail is here.
On six published criteria with fixed weights. Details are on how we rank.
A weighted reading of what each company publishes — not a claim about client results.
Yes. Each agency profile prints the page the score came from.
