Finding someone to look at a broken AC on a hot afternoon usually means calling down a list and leaving voicemails. This site shortens that. You call one number, describe the problem, and you are put through to an independent contractor who handles that kind of work in Poway.
The pages here explain common problems in plain language, such as why an AC runs without cooling or why a furnace lights and then shuts off, so you can describe what is happening and ask better questions when the contractor arrives.
