It has separate gas, electric, two hot water heaters, etc. 

I recently have a water leak in a house.

They had no clue why and found out through their neighbor that the utility water meter was leaking.

We have the highest Gas Tax of the 50 States.

Almost bought myself a property with a major leak because the seller sent proof with receipts but I dodged a bullet when I conducted my own re-inspection!

Instant water heaters take up less space and come in electric or gas versions.

He them procede to tell me it had hair line crack and that possibly the water was leaking from there and that it was a wear and tear because those pans only last so long. 

We know that a dual fuel system would be more optimal, but the cost of running a gas line and venting is likely higher than adding another circuit for the heat strip.Furthermore, we are looking for recommendations for an HVAC installer in Chicago.

Long story short, I ended up buying that condo, only to find out, after one month, that my living room windows were leaking big time during the stronger rains.

The roof begun leaking this week and has caused water damage to the ceiling of my unit and I notified the HOA of my issue on Monday.
