“We have a vacation rental. The toilet started to flood the bathroom. Our guest called us at 9:30 pm. We tried two other companies, and we were left hanging. We decided to give KC’s 23 1/2 Hour plumbing.
We called them just after midnight and Gary arrived at 1:00 am. Right on time. He tried everything he could to clear the blockage. It was too late at night to use the “Big Guns.” He came back with Frankie and they were able to clear everything. They were professional, kind, knowledgeable, informative, and nice guys. Thanks guys. You have earned a customer for life.”

Know What to Expect Before You Replace Your Furnace or AC
Installing a new furnace or air conditioner is a big investment—don’t get caught off guard by hidden costs or last-minute issues. California’s building codes are no joke, and skipping a detail like outdated ductwork can throw your whole project off track.
Every HVAC installation we do includes a free consultation. It helps you:
- Avoid budget surprises
- Maximize your system’s performance
- Prevent unnecessary delays
Forget about hard water
Installing HydroFLOW® beats Palm Desert’s hard H2O, making it cleaner and healthier. It’ll taste better and protect your water heater (and other appliances) by extending lifespan.
One of our plumbers will show you the chemical-free ionization that zaps mineral scale, bacteria, and algae—while keeping the good minerals you need for hydration.
I had an outdated water softener and RO system and needed an estimate. Dana from KC’s 23 1/2 Hour Home Services was fantastic. He arrived on time, asked a few simple questions, and recommended the perfect system for my needs. He was prompt, professional, and took the time to explain everything clearly. No pushy sales tactics—just straightforward, honest advice. I was really impressed by Dana’s knowledge and professionalism, and I’d highly recommend him to anyone looking for quality service!
Ask A Pro
Yes! Many of our customers in Palm Desert are seasonal homeowners. Our team of plumbers and technicians will handle maintenance or service while you’re away—and even prep your home before you return.
Yes, we handle the paperwork for you. We’ll secure permits for HVAC and plumbing repairs, installations, replacements and remodels. We know the local permit process inside and out and will take care of it so you can relax knowing everything is done right.
You can snake your drains anytime you have a slow or gurgling drain. We recommend it! But if you are not able to clear it with a simple snaking, we recommend calling a plumber right away. While chemicals like Drano are popular among homeowners, they cause more harm than good in the long-run and eventually lead to costly plumbing repairs.
Twice a year is best—especially if your plumbing system sits unused for long periods. It keeps buildup, clogs, and corrosion away.
Absolutely. We’ll do any air conditioning installation from start to finish—including system sizing and setup for desert weather. If you bought the unit from someone other than us, we’ll happily install it but cannot provide warranties(we only warranty our American-made equipment).
During installation, if your air ducts need resizing to keep up with code, we make the process smooth and straightforward so your air conditioning is up to code.
Our HVAC maintenance covers all key components: filters, safety checks, coils, and efficiency tests—to prevent bigger issues and extend your unit’s life.
Yes—we offer expert recommendations and full-service replacements that prioritize efficiency, performance, and long-term savings. Whether you need a new water heater or toilet, we’ll make sure you have the most efficient and up-to-date model for your budget.
Absolutely. Dust and sand can build up in your ducts quicker than in other climates. Regular duct cleaning improves your indoor air quality and helps your system run more efficiently—especially if your home sits unused part of the year.
Every 3 to 5 years is typical—but if your home sits vacant part of the year, cleaning every 2 to 3 years can help prevent buildup in ducts from dust, sand, and desert debris. If you’ve had recent renovations or notice more dust than usual, it’s worth doing sooner.
True Quality Lasts
Since 1978, we’ve kept one promise: to always do right by our customers. Our founder, Kelly, started KC’s 23 ½ Hour because he knew our community deserved honest and reliable service.
Our team is carefully trained, certified, and background-checked so you can trust us today—and for years to come. We back our work with strong warranties because we believe true quality lasts. We’re here for you now and well into the future.
