Valley floor to High Desert
Solar pool heating in San Bernardino County
One county line holds two very different pools. On the valley floor around Redlands and Fontana, the swim season starts later and ends earlier than the weather suggests. Up past the Cajon Pass, the sun is fierce all day and the water hands most of it back after dark. Same answer, sized differently.
Below the Cajon Pass
Redlands, Yucaipa, and the inland corridor
Redlands is one of the busiest cities in our whole book of work, and Yucaipa is right behind it. Both are full of pools dug back when gas was cheap, sitting under some of the most dependable sun in California, on roofs with real room to work.
West of there, the corridor through Rancho Cucamonga, Fontana, Ontario, Upland, Montclair, Chino, and Chino Hills is steady work for us year-round, and so is the San Bernardino core — Highland, Colton, Rialto, Grand Terrace, and Loma Linda.
What all of it shares is a season shorter than the thermometer implies. Afternoons are hot from May on, but water is stubborn: an unheated pool is still cold in May and cold again by late September — most of the year spent looking at it instead of getting in. For the mechanics rather than the pitch, read how solar pool heating actually works.
Above the Cajon Pass
The High Desert is not an exception for us
Apple Valley, Hesperia, and Victorville are routine runs, not favors. Apple Valley alone accounts for more of our work than most cities on the valley floor, and we're regularly in Oak Hills, Phelan, and Adelanto too.
It's a genuinely different pool problem up there, though. At close to 3,000 feet the sun is fierce all day and the temperature falls off a cliff after dark, so a system has to be sized for the overnight loss and anchored for the wind rather than copied from a Redlands job.
That's enough of its own subject that it gets its own page — including what actually happens to the panels when it freezes.
Between the two
Foothill and mountain neighborhoods
The closer your house sits to the mountains, the faster your pool cools once the sun is off it. Homeowners in the upper reaches of Yucaipa, Highland, and the north end of Rancho Cucamonga notice it in spring and again in early fall, when a pool two miles downhill is still comfortable and theirs is not. It's a real effect, and a sizing question rather than a reason to skip solar — the fix is more collector area and a cover, and we'll spell out both in the estimate.
Higher still, Lake Arrowhead, Crestline, and Big Bear are inside the area we cover. Yucca Valley, Joshua Tree, and Twentynine Palms are ours as well, though we reach those from the desert side — they're on the High Desert page along with everything else above the pass. The whole map is on the service areas page.

One family company, one standard, whether the job is a new array in Redlands or a warranty swap in Victorville. Licensed C-46 solar contractor, license #924564.
New installations
Sized to your pool and to where in the county it sits, usually finished in one to two days. We paint the exposed pipe to match the house before we go.

Desert sun and hard freezes are rough on plumbing and hardware. We find the leak, fix it, and pressure-test before we call it done.

Panels carry a 12-year manufacturer warranty. If yours are still covered, we handle the inspection and the claim paperwork and swap like for like.

Buying a house with panels already up there, or wondering if an old array is worth keeping? We'll tell you straight, including when it isn't.
Book an inspectionPanel removal
Re-roofing, or done with a dead system someone else installed? We pull the array and plumbing off cleanly and leave the roof ready.
Arrange a removalPrice it yourself
Find your house on satellite imagery, lay the array out yourself, and get a real number in a few minutes. No appointment, no salesperson.

Don't take our word for it
We publish the actual water temperatures
Most of this industry sells with adjectives. We wired a sensor into a working system and put every reading on the website — hour by hour, month by month, warts and all.
Fair warning about which pool: our sensors sit on a valley-floor system in Riverside County. Those numbers read like a Redlands or Chino pool, not an Apple Valley one — up the hill you'd see a deeper overnight dip. We'd rather say so than let a chart oversell.
FAQ
Questions we get in this county
That's the argument for solar, not against it. San Bernardino County gets more usable sun than almost anywhere in the country, but water is stubborn — an unheated pool on the valley floor is still cold in May and cold again by late September, so most of the year you're maintaining a pool you're looking at rather than swimming in. Collectors are what turn a short midsummer window into most of the year.
Regularly — for installs and for service calls afterward, which matters more than it sounds, because a warranty is only useful if somebody will drive up the pass to honor it. Everything above the Cajon Pass has its own page: solar pool heating in the High Desert.
Usually, and the two work together rather than competing. A lot of pools around Redlands and Yucaipa were dug when gas was cheap and now get used a fraction of what they cost to run. Solar carries the ordinary days for nothing, and the gas heater stops being the thing you budget for and becomes the thing you switch on for a cold snap or a party. Nothing gets ripped out to do it.
Often, and out here it's frequently the better answer anyway. A rack along the fence line, beside the equipment pad, or set into a slope does the same job as a roof array, and the big lots up the hill have room for one. If the roof is still the right call but faces east or west, that works too — it just needs extra collector area. You'll see several ground mounts in our install gallery.
Lake Arrowhead, Crestline, and Big Bear are within the area we serve, and we'll come look — though at that elevation we'd want an honest conversation about how long a realistic swim season is before you spend anything. Yucca Valley and Joshua Tree we cover as well, but from the desert side; details are on our High Desert page.
A properly sized system runs about 10 to 15 degrees above an unheated pool, which on the valley floor generally turns a short midsummer window into comfortable swimming from roughly May into October. A cover stretches it further at both ends. More sizing and season questions are answered on our general FAQ page.
