A New Boiler Sized for the House You Actually Live In
Replacement boilers selected from a measured heat loss, piped for long life and commissioned before we leave.
The boiler in the basement was probably sized decades ago, often generously, and the house has changed since. We calculate what your home in Lompoc, CA needs today and install equipment that matches it.

When Replacing the Boiler Makes More Sense Than Repairing It
Boilers are long-lived machines, and a well-maintained cast iron unit can run for decades. Replacement usually becomes the right call for one of three reasons: the heat exchanger has started to leak or crack, the controls and parts are no longer made, or the fuel bill has grown large enough that a modern boiler would pay back a meaningful share of its cost over time.
There is also a safety threshold. A boiler that cannot pass a combustion test after reasonable repairs, or that vents poorly into an aging chimney, is not a system to keep patching. In those cases we document the readings and show them to you, because a replacement recommendation should be backed by something you can see.
What we will not do is recommend a new boiler because the old one is simply old. If the heat exchanger is sound and parts are available, a repair is often the smarter spend, and our Boiler Repair team handles those visits every day.

How We Size and Specify a Replacement Boiler
Sizing is where most boiler installations go wrong. These are the steps we take before recommending any model.
Room-by-room heat loss
We measure walls, windows, ceilings and floors and account for insulation levels to calculate how much heat each space loses on a design cold day. That number, not the old boiler's rating, sets the target output.
Emitter survey
Baseboard, cast iron radiators and radiant floors release heat differently. Counting and measuring them tells us what water temperature the system needs, which decides how much condensing efficiency is realistically available.
Piping and zoning review
We map existing zones, circulators and valves. Some systems benefit from primary and secondary piping or a hydraulic separator so a modern low-mass boiler is not starved of flow.
Venting and fuel assessment
Condensing boilers vent through sidewall plastic pipe, while conventional boilers need a properly lined chimney. We confirm the venting route and the gas or oil supply can support the new unit.
Written proposal
You receive the recommended model, the scope of piping and venting work, permits and a single flat installed price.
Choosing Between Condensing, Conventional and Combi Boilers
Each type suits a different home. This comparison is the starting point for the conversation we have with you on site.
| Boiler type | Best suited to | Things to weigh |
|---|---|---|
| Condensing, heat only | Homes with radiant floors or ample radiation that can run cooler water | Highest efficiency, needs condensate drain and sidewall venting |
| Conventional cast iron | Older systems with high-temperature radiators or steam | Durable and forgiving, lower efficiency, chimney must be sound |
| Combi boiler | Smaller homes wanting heat and on-demand hot water from one unit | Saves space, hot water output limited to one or two fixtures at a time |
| Boiler plus indirect tank | Larger families with heavy hot water use | Excellent hot water supply, uses more floor space |
A heat pump can also be part of the discussion for some homes. If you are curious whether that route suits your house, see Heat Pump Installation for how we evaluate it.
Installation Details That Decide How Long the New Boiler Lasts
A modern boiler is only as good as the water running through it. Old systems carry sludge and magnetite that can clog the narrow passages of a new heat exchanger within a few seasons. We flush the existing piping and, where it makes sense, install a dirt separator and magnetic filter so debris is captured before it reaches the boiler.
Air elimination, expansion tank sizing and circulator selection are matched to the new system rather than carried over. On condensing installations the condensate line is run to a proper drain with a neutralizer, and the venting is pitched back toward the boiler as the manufacturer requires.
Controls matter just as much. Outdoor reset, which lowers water temperature on milder days, is one of the biggest efficiency gains available and is built into most modern boilers. We set it up and tune it to your emitters so the house stays comfortable without the boiler running hotter than necessary.
Finally, we commission the system: combustion analysis, gas pressure verification, safety control tests and a full heating cycle on every zone. You get a walkthrough of the new controls and the manufacturer warranty is registered in your name.
Signals That the Current Boiler Is Near the End
Heat exchanger seepage
Rust trails, white mineral crust or water pooling beneath the sections point to a failing exchanger, which is rarely worth repairing.
Repeated repairs each season
When the same system needs service several times a winter, the repair spend starts to rival a monthly payment on new equipment.
Parts that are no longer made
Obsolete controls or burners may force costly workarounds or leave you exposed to a long outage.
Rising fuel use without explanation
Scale buildup and worn burners quietly drag efficiency down year after year.
Planning Ahead Beats a Midwinter Emergency
Replacements done in spring, summer or early fall give you time to compare options and schedule around your household. If your boiler is showing its age, an assessment before the heating season costs you nothing in comfort.
What a Flat Installed Price Should Cover
A boiler quote that lists only the equipment tells you very little. Ours spells out everything required to hand you a working, inspected system: removal and disposal of the old boiler, the new boiler and its controls, circulators, expansion tank, air separation, any dirt separator, near-boiler piping, venting materials, condensate neutralizer, gas or oil connections, the permit and inspection, and full commissioning.
If existing radiators need new valves, a zone needs its own circulator, or the chimney requires a liner for a conventional boiler, those items appear as separate lines so you can see why they are there. Nothing is added after the fact without your written approval. Financing through a third-party lender is available subject to credit approval, and we are happy to show you the monthly figures next to the cash price.
Comparing proposals is easier when you know what to look for. Ask every contractor whether the quote is based on a heat loss calculation, whether the system will be flushed, and who registers the manufacturer warranty.
Questions Homeowners Ask Before Replacing a Boiler
Most straightforward residential swaps take one to two days, including removal of the old unit, piping, venting and commissioning. Jobs that change fuel type, convert from chimney to sidewall venting or rework zoning can take longer, and the proposal will say so.
Usually, and often with room to spare, since modern wall-hung boilers are far smaller than floor-standing cast iron units. The venting route and condensate drain are what really dictate placement.
Rarely. Existing radiators and baseboard generally work well. The heat loss and emitter survey tells us what water temperature they need, and we choose and program the boiler around that.
Boiler replacements typically require a mechanical permit and, for gas equipment, an inspection. We pull the permit and schedule the inspection as part of the installed price.
