Ownership and Links

Who owns the site

Hum Drip Hiss is owned by the same people who own Plumbing Supply and More (a plumbing and HVAC supply house), SoftPro Water Systems and Quality Water Treatment (both sell water softeners). It also has a business tie to Central Plumbing & HVAC, a service company that works only in Bucks and Montgomery counties, Pennsylvania.

Because of those ties, Hum Drip Hiss does not call itself neutral, and every link to one of these businesses carries a short ownership note beside it. Whatever business once used this web address, Hum Drip Hiss is unrelated to it.

Which pages carry business links

Links to these businesses appear on 15 pages only, and only where they help explain a symptom: what a part is called, what a technician may replace, or how a local company's service page is laid out. Parts that belong to technicians, such as capacitors and igniters, are shown so readers know what they look like, never as a do-it-yourself fix.

• When to stop and call an HVAC technician
• Safe HVAC checks before you call
• Furnace or AC squealing noise
• Furnace clicking but no heat
• AC unit buzzing or humming
• Dirty sock syndrome and musty vent smells
• Furnace leaking water
• AC leaking water inside
• Frozen AC coil
• Furnace won't ignite
• Furnace blinking red light
• Thermostat blank
• Uneven room temperatures
• High electric bill
• House humidity too high or too low

No other page, including the home page and the safety-critical gas and carbon monoxide pages, links to any of these businesses.

What linked businesses can't do

The linked businesses cannot write, edit or approve any page, and none of them can pay for a link, a mention or a better position. Safety advice, the stop-and-call signs and the order of likely causes are set by the makers' and agencies' published guidance, not by what any linked business sells.

Links to these businesses are ordinary links. Nobody pays to be linked here.
