Frequently Asked Questions
Does my home need a gas line upgrade for tankless?
Many Chicago homes require a gas line upsizing to support the higher BTU demand of a tankless unit. We assess this during your free estimate and include the upgrade in the bundle price when needed.
How long does installation take?
Most tankless + recirculation installs are completed in one day. Permit inspection may add 1–2 days depending on the city inspector's schedule.
Is a permit required?
Yes — all water heater replacements in Chicago require a permit. We pull and manage the permit for you.
What brands do you install?
We install Lennox, Navien, Noritz, and other top-tier tankless brands. We'll recommend the best fit for your home's BTU load and budget.
