Drain & Sewer & Hydro Jetting
Clogged drains and slow-moving pipes are more than inconveniences – they can lead to backups and damage. We offer:
Hydro jetting to clear stubborn blockages with high-pressure water
Sewer line cleaning and repair for long-term reliability
Camera inspections to pinpoint the exact cause of recurring clogs
Hydro jetting is especially effective for grease buildup, scale, and tree root intrusions that standard snaking can’t fix.


Water Heater Repair & Replacement
Hot water is essential for comfort and health. We service all major brands and models of:
Traditional tank water heaters
Tankless water heaters
Hybrid and high-efficiency units
Our services include troubleshooting leaks, replacing heating elements, flushing tanks to extend life, and full system replacements when needed. If you’re considering an upgrade, tankless water heaters provide endless hot water and improved efficiency.
HVAC - Heating & Air Conditioning
Our HVAC specialists keep Fountain Valley homes comfortable all year long. We provide:
AC repair, installation and seasonal tune-ups
Furnace repair and installation
Ductless mini-split solutions for room-by-room comfort
Indoor air quality improvements like filters and purifiers
Regular HVAC maintenance reduces energy bills and prevents breakdowns during the hottest or coldest months.

Common Homeowner Problems & Solutions
Leak Detection & Repair
Leaks often go unnoticed until they cause significant damage. Using advanced leak detection, we find water hidden under floors, inside walls, or beneath concrete slabs. Early detection prevents mold, structural damage, and high water bills.

Slab Leaks & Repiping
Southern California homes are no strangers to slab leaks. Left untreated, they can undermine your foundation. We provide trenchless and minimally invasive repair options. For aging plumbing systems with frequent issues, we also perform whole-house repiping to deliver lasting peace of mind.
Clogged Drains & Sewer Line Issues
From kitchen grease to invasive roots, our drain and sewer services restore flow quickly and safely. With hydro jetting, we clean pipes thoroughly so problems don’t come back in a week. Our team also offers trenchless sewer line replacement for minimal property disruption.
HVAC Breakdowns & Maintenance
Strange noises, poor airflow, or inconsistent temperatures often signal HVAC trouble. Our technicians repair faulty thermostats, blower motors, compressors, and more. Annual maintenance ensures efficiency, extends system life, and reduces costly breakdowns.

Water Heater Failures
Cold showers, rusty water, or leaks around your water heater are clear warning signs. We service both gas and electric water heaters, providing repairs when possible and honest recommendations for replacement when needed.

I use these guys for everything. Super prompt and efficient, kind service, and fair pricing. I had a very old water heater, which stopped working yesterday. I never realized how much I appreciated hot showers until I wasn’t able to take one. Having young children made this problem 10 times worse, it was WW3 trying to get them clean! I called my go to Plumber, Coast, Last night at 10 PM requesting a service for the next morning. The lady I spoke to was kind and told me I would get a call back around 7 AM today. First thing this morning, I got a call from Coast Letting me know they can have a technician there at 8:30 AM. Nate Showed up on time and was awesome! He immediately went to work on my water heater, explaining everything about it in clear detail. I decided to opt for a new one as mine was shot. Nate gave me a quote with all labor included and explained he can get it done right away. I had checked pricing online prior to his arrival. His quote was very fair and the fact he could get it done immediately was exactly what I was looking for. I had to get into work, so I was able to take off while Nate did the full job, giving me updates along the way. 4 hours later, and the water heater is in and rocking! NATE THE GREAT!!
