Call (818) 855-1269 to schedule a boiler inspection.

How We Size Your New Boiler

Sizing your new boiler is the most important step because an oversized unit short-cycles and wastes fuel, while an undersized one runs constantly and never keeps up on cold mornings.

Our team uses a heat load calculation to properly size the boiler. The calculation factors in:

  • Total heated square footage of your home
  • Ceiling height across each room
  • Insulation quality in walls, attic, and floors
  • Window count, size, and sun exposure
  • Air leakage and overall home age
  • Existing radiator capacity or radiant floor layout
  • Local Sherman Oaks climate data
  • Most homes fall between 30 and 60 BTU per square foot, but the right number depends on the factors above. We never recommend a boiler size based on square footage alone, since that guess often leads to oversized units, higher fuel bills, and shorter equipment life.

Call (818) 855-1269 to schedule your free in-person boiler sizing assessment.

Types of Boilers We Install

We install gas, electric, and oil-fired boilers of all major brands. Our team helps you pick the right one based on your home, budget, and existing utility setup.

Gas Boilers

Gas boilers are the most popular choice because most LA homes already have a natural gas line. They warm water quickly, run reliably, and pair well with both radiator and radiant floor systems. We install standard gas boilers (80 to 85 percent efficient) and high-efficiency condensing boilers (90 to 97 percent efficient) for homes that want to lower long-term fuel costs.

Electric Boilers

Electric boilers use electric heating elements to warm the water, with no combustion involved. They are recommended for homes without a gas line, smaller condos, or properties where venting is hard to route. Electric boilers also take up less space and run more quietly than gas units, though they cost more to operate where electricity rates are high.

Oil-Fired Boilers

Oil-fired boilers run on heating oil stored in an on-site tank. They are less common in Sherman Oaks but still found in some older homes built before the area was fully connected to natural gas service. We install replacement oil-fired boilers and also help homeowners convert from oil to gas when the existing fuel tank is failing.

Call (818) 855-1269 to find the right boiler type for your home.

Signs You Need a New Boiler

You need a new boiler when your current unit is past 15 years old, facing repeat breakdowns, or running far less efficiently than it used to. Spotting these signs early helps you avoid a full system failure during the coldest months of the year.

Common signs you need a new boiler:

  • The unit is 15 to 20 years old or more: Boilers lose efficiency every year past this mark, and parts become harder to source.
  • Repeat repairs in a single season: When repair bills start increasing, replacement often costs less long-term.
  • Heating bills keep climbing: Older boilers lose efficiency over time, which shows up directly on your monthly bill.
  • Uneven heating across the home: Some rooms warm up while others stay cold, even with the thermostat set high.
  • The boiler runs constantly without keeping up: A sign the system can no longer match your home’s heat demand.
  • Visible rust, corrosion, or recurring leaks: Often points to a failing heat exchanger or worn internal parts.
  • Strange noises during operation: Persistent banging, kettling, or rumbling often signals scale buildup or component wear.
  • Yellow or orange pilot flame: A sign of incomplete combustion, which can release carbon monoxide and signals end-of-life issues.
  • Frequent automatic shutoffs: The boiler trips its safety controls more often as internal parts wear out.

Schedule a boiler replacement if you notice any of these signs. Our team gives you an honest comparison of repair vs. replacement based on the actual condition of your boiler.

Our Boiler Installation Process

Our boiler installation process follows a clear, code-compliant approach handled fully by our licensed and experienced technicians.

Here is what happens when you book with us:

  • Step 1 – Free in-person estimate: A licensed technician visits your home, runs a heat load calculation, checks gas and water lines, and reviews your venting paths.
  • Step 2 – Boiler selection: We help you compare brands, fuel types, capacities, and efficiency ratings so you choose the right unit for your home and budget.
  • Step 3 – Permits and prep: Our team handles LADBS permits, California code paperwork, and preps the install area to keep the job clean.
  • Step 4 – Removal and installation: For replacements, we safely disconnect and remove the old boiler. We then install the new unit with proper gas, water, venting, and electrical connections.
  • Step 5 – Testing and walk-through: Final pressure tests, leak checks, safety control verification, and a full walk-through so you know how to operate the new system.

Most installs take 1 to 3 days, depending on the system type and any required line or vent updates.

FAQs

Most boiler installations in Sherman Oaks take 1 to 3 days from start to finish. Same-fuel-type swaps often finish in a single day, while new installs that need fresh gas lines, venting, or electrical work may take longer. Our team gives you a clear timeline after the initial consultation.

Boiler installation costs in Sherman Oaks depend on the unit type, size, fuel source, and any updates needed to gas, water, or vent lines. Standard gas units cost less than high-efficiency condensing models, and replacements are usually cheaper than first-time installs. We provide a clear quote after property assessment.

Boiler installation in Sherman Oaks requires a permit from LADBS to comply with the California Plumbing Code and Title 24 standards. Our team handles all permit paperwork and required inspections as part of the install. This keeps your project fully code-compliant and protects your home's value at resale.

The right boiler size depends on your home's square footage, ceiling height, insulation level, and existing radiator or radiant floor setup. Most homes fall between 30 and 60 BTU per square foot, but proper sizing requires a full heat load calculation. Our technicians measure every factor during the free in-person estimate.

A new boiler typically lasts 15 to 20 years with regular maintenance. High-efficiency condensing units often fall within this range, while older cast-iron boilers can last longer with proper care. Skipping yearly service often shortens that lifespan by several years.
