Serving Washington County Since 1978
Your St. George Home Comfort Experts
Marlin Plumbing Heating & Air has been serving St. George, Utah homeowners since 1978. Whether you need a plumbing repair, furnace tune-up, AC installation, or emergency service at 2 AM, our experienced team is ready to help.
We understand the unique challenges St. George homes face — extreme summer heat that pushes AC systems to their limits, hard water that damages pipes and appliances, and winter temperatures that demand reliable heating. With 48+ years of local experience, we build solutions that work for Southern Utah.
St. George has grown by more than 30% in the last decade, which means thousands of homes built in the 1980s and 90s are now at the age where plumbing and HVAC systems need serious attention. Galvanized supply pipes from that era corrode from the inside — sometimes without visible leaks until a pipe bursts completely. We inspect and replace these systems every week across the city.

Common St. George Plumbing & HVAC Problems
Hard Water Scale Buildup
At 15–25 grains per gallon, St. George's water is some of the hardest in Utah. Scale accumulates inside water heaters, clogs showerheads and aerators, and reduces flow through older pipes over time. We diagnose and treat hard water damage every day in this city.
Aging Galvanized Pipes
Thousands of St. George homes built in the 1970s–1990s still have galvanized steel supply lines corroding from the inside. Discolored water, reduced pressure, and frequent small leaks are warning signs. We replace these systems regularly across the city.
Summer AC Failures
When daytime highs push 114°F, air conditioners run continuously for weeks at a time. Capacitor failures, refrigerant leaks, and coil freezes spike during July and August. Annual spring tune-ups are the most reliable way to avoid a breakdown during the hottest stretch.
Got Questions?
St. George Plumbing & HVAC FAQ
Practical answers based on the questions St. George homeowners ask most.
Washington County water runs 15–25 grains per gallon of hardness — among the highest in the state. That calcium and magnesium buildup clogs showerheads and aerators, shortens water heater life by 30–50%, and eventually reduces flow through older pipes. A whole-home water softener is one of the best investments a St. George homeowner can make.
