What we could not verify
Everything else that goes into a ranking on this site is read from a company's own website: the services it lists, whether it installs ductless mini splits or heat pumps, posted prices, financing, warranty terms and service area. We did not find a website we could confirm belongs to John David Lang A/C & Heating, so none of that is on record here. If this is your company, send us the site and it will be read and scored on the next update.
