Chicago water heater repair & replacement
Quick gut-check: if water is flowing where it shouldn't be, call. If it's just a slow drip, you can wait until morning at standard rates. Service area covers Chicago proper plus the metro suburbs. After-hours is real after-hours, not "we'll get back to you tomorrow."
One we ran last year
Last spring we got a call from a homeowner near the outskirts Chicago. Tankless unit producing cold-water sandwich. Diagnosis: calcium scale in the heat exchanger. We descaled the unit and recommended annual maintenance, ran the test, and were out the door in about two hours. Total: $1812 including parts.
What you're paying for
Water heaters last 8 to 12 years on average — less in hard-water regions, more if the anode rod gets replaced every 4 years. Most calls come at end-of-life when the tank starts leaking from the bottom seam.
When the tank goes, swap it. Repair on a 10-year-old tank that's leaking is throwing money away. We carry standard 40 and 50 gallon gas and electric tanks on our trucks for same-day install. Tankless replacements take 1–2 days because of the gas-line and venting work.
If you have a tankless unit and you're getting cold-water sandwich (hot for 30 seconds, cold for 10, hot again), it's almost always scale buildup in the heat exchanger. Annual descaling fixes it — $225 to $380 — and is required by the manufacturer to keep your warranty valid.
Brand-wise, we install whatever you want. Defaults we keep stocked: Rheem and AO Smith for tank, Rinnai and Navien for tankless. Bradford White on commercial.
Water Heater Repair & Replacement in Chicago — what's typical here
Around here, the most common calls we run come from older homes near the city center and newer subdivisions on the fringe — different problems, same crews.
