The only real difference is heat: power washing uses hot water, pressure washing does not. Which one Pensacola driveways, siding, and roofs need.
The only real difference between pressure washing and power washing is heat. A power washer runs the water through a burner before it reaches the nozzle; a pressure washer delivers the same water cold. The pump, the pressure, and the tips are otherwise identical. In Pensacola that difference earns its money on one specific problem - oil and grease on concrete - and matters very little on everything else, because most of what stains a Gulf Coast home is living algae that chemistry kills better than temperature does.
Heat, and only heat. A hot-water machine heats water to roughly 140 to 200 degrees at the tip; a cold-water machine puts out whatever comes from your spigot. Both can run the same pressure (commonly 3,000 to 4,000 PSI for professional units) and the same flow. Because the two words get used interchangeably in advertising, the wording on a Pensacola truck or website tells you almost nothing. If hot water matters for your job, ask the direct question: does the machine have a burner, and will it be used on my property?
Hot water breaks down petroleum and grease in a way cold water cannot, so it earns its keep on a short list of jobs:
On those surfaces heat softens the contaminant so the pressure can carry it away instead of just polishing around it. For a homeowner, that usually means a hot-water pass is worth requesting on one section of concrete, not on the whole house.
On the stains that actually cover Pensacola homes, heat is close to irrelevant. Black shingle streaking, the green film on north-facing vinyl, the slick gray growth on a shaded lanai, and the salt-and-pollen haze that settles on everything within a few miles of the bay are all biological. They are killed by the cleaning solution, not by water temperature - a hot rinse that skips the chemistry just knocks the surface layer down and the growth returns in weeks. Heat can also work against you: it can soften vinyl siding, and on sealed pavers or stained wood it can cloud or lift the finish.
For the large majority of driveways here, cold water with a flat surface cleaner and the correct pre-treatment does the whole job: pine pollen film, tire scuff, the black growth that creeps in from the shaded edges, and the general Gulf Coast grime. Hot water is the targeted upgrade for the oil drip zone under where the car parks, and for rust it is neither - rust needs an oxalic-based treatment and no amount of heat or pressure will touch it. That is how our driveway and concrete cleaning in Pensacola is built: the right method matched to each stain rather than one setting used everywhere.
In residential advertising, largely yes - most companies using it are running cold-water equipment. The more useful question for your house is not hot versus cold, it is high pressure versus low. That distinction decides whether your roof, siding, and screen enclosure survive the job, and it is worth reading before you book anything: soft washing vs pressure washing.
Does power washing cost more than pressure washing in Pensacola? When a burner is genuinely being used, expect a modest premium - hot-water equipment costs more to buy, burns diesel, and is slower to set up. If a quote is higher purely because it says "power washing," you are paying for the word, not the burner.
Can hot water damage my home? It can. Heat plus pressure on vinyl siding risks softening and warping panels, and on sealed pavers, stained decks, or painted trim it can cloud or strip the finish. Those surfaces should be soft-washed with cool water and the right solution instead.
Will either one remove the black streaks on my roof? Neither, at pressure. Roof streaking is Gloeocapsa algae and the only safe fix is a low-pressure soft-wash treatment that kills it at the root - blasting a shingle roof hot or cold strips the granules and shortens the roof's life.
