Takes about a minute. No obligation.
A boiler contractor quoting in Harris County cannot size the system off a catalog spec and call it done. 403 severe weather events were recorded in Harris County, Texas between 2015 and 2024. At that rate, severe weather is part of the normal operating environment, and a system installed without accounting for what this climate regularly throws at it will be undersized or undersealed for the actual load. Insulation values, combustion air paths, and expansion calculations all shift when the baseline conditions are this demanding. A contractor who treats this as a standard install ships a system built for somewhere else.
Ductwork laid down for an earlier generation of equipment carries assumptions a new boiler has to work around: flow rates, trunk sizing, and return placement that made sense for what the house was built with. Half the homes in Harris County, Texas were built in 1988 or earlier (2020-2024 ACS 5-year). A contractor quoting a boiler installation here will open the duct system before pricing anything, because what is already in the walls either fits a modern unit's demands or it does not, and that answer changes the scope of the job.
What a Boiler Installation Covers
The boiler itself sits in a mechanical room, basement, or utility closet and is the heart of the system. A contractor mounts the unit, connects it to the home's water supply, and ties it into the flue or venting system that routes exhaust safely out of the house.
Radiators or baseboard convectors sit in the living spaces and are the pieces a homeowner sees day to day. The expansion tank, circulator pump, and pressure relief valve each mount close to the boiler and keep water moving through the system at a safe and steady rate.
The drawing shows a typical layout, and a licensed contractor determines what applies to this specific house.

Harris County weather puts real demands on heating equipment over its lifetime. How hard a boiler has to work, and how often, is shaped by what the local climate actually does.
