Every home and system is different. These answers help you prepare; an on-site diagnosis confirms the right next step.
Ask another questionDoes tankless mean unlimited hot water?
A properly sized unit can heat continuously within its flow capacity, but simultaneous demand can still exceed the system.
Can any home switch to tankless?
Not without evaluation; fuel or electrical capacity, venting, gas lines, water quality, space, and demand all matter.
Do tankless water heaters need maintenance?
Yes. Inspection and water-side service may be needed depending on the equipment and local water conditions.

We called McHenry Plumbing on Friday to get an estimate to repair the hot water heater issue and discussed the situation with them. Based on the quote we received and age of the unit we decided to replace it. They scheduled us on Monday. The two plumbers arrived when scheduled and were professional and pleasant and were finished in about 2.5-3 hours. I would recommend this company and will use them in the future if we need their services.
Excellent service! Our sump pump went out and we had water in the basement, McHenry Plumbing (Heating & Air) sent Butch over asap. I can't say enough about Butch, he was excellent! He took the time to explain everything to me, such a nice guy, very professional and great to work with! Thanks so much!
