Semper Fi Heating & Cooling has earned a reputation across the Valley for honest, reliable HVAC services. While locals recognize the name for air conditioning and heating, Semper Fi’s plumbing division has grown into a robust, full-service department that’s making an impact in homes Valley-wide.
Plumbing department manager John Coppinger joined the company in 2022 and took on the leadership role the following year. With more than 15 years of experience in both residential and commercial plumbing, he saw Semper Fi as a place where he could be part of something larger — where doing right by customers was a shared value.
“I’ve worked in a lot of different settings, but Semper Fi stood out because of its culture,” Coppinger said. “Everyone here is committed to excellence. We’re not just fixing pipes or drains; we’re helping people feel safe and confident in their homes.”
The plumbing team at Semper Fi handles a wide range of services. Whether it’s a clogged drain, a malfunctioning water heater or a full water treatment system installation, they have the tools and training to get the job done right. Their services include water heater repair and replacement (both tanked and tankless), water softeners, pipe and gas line repairs, repiping and preventative maintenance like drain cleaning, water heater flushes and more.
Coppinger said one of the most important parts of the job is looking at the bigger picture.
“Anyone can clear a drain,” he said. “But we want to understand why it’s happening and make sure it doesn’t keep happening. That’s how we save customers time, money and frustration in the long run.”
To make it easier for homeowners to stay on top of maintenance this summer, Semper Fi is offering several timely plumbing specials. Right now, customers can schedule a Level 1 Drain Cabling or Water Heater Flush and Fill service for just $49 each. These services help prevent backups and extend the life of essential systems.
Other current promotions include $200 off tanked water heaters or water treatment systems, $350 off new water softeners, $500 off tankless water heaters and 15% off pipe or gas line repairs.
Preventative care, like water heater flushes and drain cleaning, helps Valley homeowners avoid costly plumbing issues.
Coppinger especially recommends the water heater flush, which can remove sediment buildup and improve efficiency.
“It’s one of those simple things that people forget about, but it makes a real difference,” he said. “If you’ve got hard water, and most of us here do, that buildup can shorten the life of your water heater if you don’t take care of it.”
The Semper Fi team also advises keeping an eye on water usage during the summer months. A sudden spike in a water bill could be an early sign of a hidden leak, inefficient system, or another issue that needs attention.
With 10 licensed plumbers currently on staff, Semper Fi’s plumbing team is built for responsiveness and reliability. They’re available around the clock and are always ready to serve with the same values that define the company — integrity, service and a commitment to the community, especially to fellow veterans.
“Whether it’s HVAC or plumbing, we treat every job like it matters, because it does,” Coppinger said. “It’s someone’s home. And we’re here to take care of it.”
