Customer Reviews

“They replaced our aging furnace and AC unit — the new system is so much more efficient. Our energy bill dropped noticeably. Been using Marlin since my parents first called them years ago. Honest family business that does right by their customers.”

“Marlin installed our tankless water heater and the whole process was seamless. Professional, on-time, and fair pricing. They handle all our plumbing and HVAC — can't recommend them enough!”

“Called Marlin when our AC went out in the middle of July — a St. George summer nightmare. They had a tech out within hours and got us cool again the same day. These guys know HVAC inside and out.”

“Had an emergency sewer backup at 2am and they were at our house within the hour. The tech was courteous, explained everything, and had us back to normal by morning. Lifesavers!”

“Marlin did our annual furnace tune-up and found a cracked heat exchanger before it became dangerous. They replaced it quickly and at a fair price. Grateful they caught it — truly looking out for their customers.”

“Installed a whole-house water softener and reverse osmosis system. The difference in water quality is night and day. Fair price, great installation, and they cleaned up after themselves.”

“We used Marlin for our new home construction plumbing. Outstanding work quality, and Chad personally checked in to make sure everything met code. The IAPMO certification gives real peace of mind.”

“Sewer camera inspection saved us from a much bigger problem. They found a root intrusion and had it fixed the same day. Straightforward pricing, no upselling. Will use again for sure.”

“Our AC died right before a family gathering. Marlin had someone out that afternoon and diagnosed the issue fast. New compressor installed the next day. Couldn't have asked for better service under pressure.”

“Used Marlin for a full re-pipe of our 1980s home. They were transparent about the timeline and cost, and the work was flawless. No more rusty water. Worth every penny.”

“Annual HVAC maintenance customer for three years running. They're always on time, thorough, and never try to sell me things I don't need. Refreshing honesty.”
