Tank vs. Tankless Water Heaters
Traditional tank water heaters store and continuously heat a reservoir of water. They are reliable and lower in upfront cost. Tankless (on-demand) water heaters heat water only when needed, offering unlimited hot water and up to 30% energy savings. We install both types and will help you choose the best option for your household size and budget.
Water Heater Repair
We repair all water heater problems including no hot water, insufficient hot water, discolored or smelly water, leaking tanks, pilot light issues, faulty thermostats, and sediment buildup. Many repairs can be completed the same day. If your water heater is beyond repair, we will give you honest replacement options.
When to Replace Your Water Heater
Most tank water heaters last 8–12 years; tankless units can last 20+ years with proper maintenance. Signs it is time to replace include rust-colored water, rumbling or popping noises, visible corrosion on the tank, or a unit that is more than 10 years old and requiring frequent repairs.
Professional Installation
Proper water heater installation requires knowledge of gas lines, venting, and local code requirements. Our licensed technicians handle everything — removing and disposing of your old unit, installing the new system, testing for leaks, and ensuring everything meets Chicago building codes.
Frequently Asked Questions
How long does water heater installation take?
Most water heater replacements take 2–4 hours. Tankless installations may take longer due to venting and gas line work. We will give you a clear timeline when you call.
What size water heater do I need?
For tank water heaters, a 40-gallon unit is typically sufficient for 1–3 people; 50 gallons for 3–5 people. Tankless sizing depends on the number of simultaneous hot water demands. We will recommend the right size during your estimate.
My water heater is leaking — is it an emergency?
A leaking water heater should be addressed promptly. Turn off the cold water supply to the heater and call us at (312) 600-2222. We offer same-day service for water heater emergencies.
Do you install tankless water heaters?
Yes. We install gas and electric tankless water heaters from leading brands. Tankless systems provide endless hot water and significant energy savings over time.
