Our Heating Installation Process
The right furnace starts with the right plan. We show up with the right tools and a strategy built for your home. From load calculations to final testing, we follow a proven process to deliver reliable heating you can count on all season.
Step 1: Comprehensive Home Assessment
Every installation starts with a detailed review of your home. We analyze insulation quality, home layout, square footage, and microclimate variations that are so common across San Jose. Homes near the foothills face different temperature patterns than those downtown, and we account for that from day one.
Our licensed professionals assess:
- Home size, for proper heating capacity
- Insulation levels, to gauge heat retention
- Airflow design, to eliminate uneven heating
By dialing in the airflow during setup, we help your heater run more efficiently and keep your entire home consistently warm.
Step 2: Selecting the Right Heating System
San Jose homeowners have options. Whether you’re upgrading an aging gas furnace, switching to a heat pump, or integrating an all-electric system, we walk you through what works best for your space and budget.
We offer:
- Gas & Electric Furnaces: Offers quick, reliable heat
- Heat Pumps: Efficient systems built for California’s year-round climate

Signs It’s Time for a Heating Replacement
Not every heating issue calls for a full replacement, but some symptoms shouldn’t be ignored. Whether you’re in the heart of San Jose or the surrounding foothills, recognizing the early signs can help you avoid unexpected breakdowns and rising energy bills.
Here are the top signs our San Jose clients face:
- System Age: Most systems lose reliability after 12–15 years
- Higher Utility Bills: A sign your system is working too hard
- Frequent Repairs: Constant fixes add up quickly
- Inconsistent Heating: Cold rooms or temperature swings
- Rattling, Clanking, or Musty Odors: Aging systems often make themselves known.
- Air That Feels Dry or Stale: Could mean your system can’t keep up with modern comfort needs.
If you’re noticing any of the above, Sandium offers free second opinions and diagnostic credits with approved furnace repairs.
Choosing the Right Furnace Size for Your Home
Some heating issues can be solved with a quick fix. Others are signs it’s time to move on. We help San Jose homeowners spot the difference so they don’t get stuck without heat when it matters most.
At Sandium, we use precise Manual J load calculations to design a furnace setup that fits your home’s needs, taking into account:
- Total Living Area: Heating needs go up with square footage, but even a smaller home can need more power if heat isn’t circulating well.
- Ceiling Height: Ceiling height affects how much air needs to be heated.
- Insulation Matters: A well-insulated home holds onto heat better, which means your system doesn’t have to work as hard, and you might even be able to get away with a smaller setup.
- Windows Make a Difference: The way your windows are built and placed can change how much heat your home gains or loses.
- Air Leakage & Duct Efficiency: Leaky ducts and hidden drafts can send your heat right out the door. Sealing things up means more comfort with less waste.
- Zoning Requires Strategy: Got more than one heating zone? Your system should be tailored to match, so every area gets just the right amount of heat.
Accounting for all of these elements is all part of our commitment to smart, high-performance heating solutions tailored to the unique homes and microclimates found throughout San Jose.

Most heater installations in San Jose, CA, are knocked out in just one day. If your system needs extra attention or custom work, we’ll keep you fully informed on the timing.

We suggest a yearly service, usually in the fall, so your system’s ready to perform all winter without surprises.
