About this site
I spent years on the office side of an HVAC company. I bought the parts, wrote the invoices, took the deliveries, ran dispatch, processed the payments, registered the equipment warranties with the manufacturers, and rode along with the techs. I hold an EPA certification. I can diagnose a system and handle basic repairs — and I know exactly why you want a licensed, insured, experienced tech doing the work instead: the license, the insurance, your city's rules, and a company that has to answer for the job afterward.
I've seen the good and the bad from the inside. Big companies aren't the enemy: they have a reputation to protect and an owner who will make a warranty claim right. I've also seen the bare minimum this industry can get away with, the sales pitch that turns a repair into a new install, and the dispatch board on a hundred-degree day when everyone got bumped and everyone is angry.
This site does one thing, for every zip code in the country. You type a zip and you get the HVAC companies Google shows for your area — the same list you'd get on Google Maps, without the ads and the "three free quotes" forms sitting on top of it. Nobody here is selling your information and nobody will call you. Pick one and call them.
The site keeps a count of which zips get searched and which listings get clicked. Nothing that identifies you.
