how big of a house is it? do you have a suite?

For most 100 amp service is fine, inspectors are really hit and miss in terms of what they know works and what they know from reading a book.

When i was working on reno's at my place the first 2 guys who work for "big" companies suggested we upgrade the panel, even though the majority of our appliances and heating were gas.

Then once i was hooked up with my contractors electrician, who had had his own company for 25+ years, a 1 man operation who would benefit hugely by "upgrading" my panel, said there was no need. We added a sub panel off the main 100amp feed and have had zero problems since.

Are your breakers doubled up because of a lack of space in the panel? is there any room to just add additional breakers?

If you have a gas furnace and gas hot water tank, even with a suite a 100a service shouldnt be a problem.

The thing with upgrading to say a 125 or 150amp service (as far as a i know) if that sometimes you cannot just simply upgrade the service using the existing feed off the line, some of those higher amperage feeds need their own pole etc.

thats when you're looking at $10,000+ for a simple upgrade that may not even help that much in the end..

An electrician can probably chime better but i think it may just be the case of an over-zealous "by the book" Inspector.
