What the Pros Say
"Don't try to save a few hundred bucks on a DIY install. I've seen too many gas leaks and flooded basements from jobs gone wrong. A professional installation means peace of mind and knowing it's done safely."

Mike Johnson
Licensed Plumber, 15 years"When we provide a quote, we're not just looking at the unit cost. We're assessing your home's existing plumbing, electrical, and venting to make sure everything is up to current safety codes and will work efficiently for years to come."

Sarah Chen
Service Manager, Apex Plumbing"The biggest variable is what we find when we remove the old unit. Are the water lines corroded? Is the ventilation inadequate for a new high-efficiency model? These 'surprises' are what a professional is trained to handle correctly on the spot."
