Why Proper Installation Matters More Than the Furnace Brand
Buying a good furnace brand is important, but Proper installation is what determines:
How well your HVAC system heats your home
Your heating bills and overall heating costs
How often you’ll need repairs
Your family’s safety around gas connections and combustion gases
With Galaxy, you get a licensed HVAC contractor who pays attention to every detail:
Correct right furnace size based on the size of your home
Proper electrical wiring, gas pressure and flue pipe design
Safe routing of condensate drain and venting for high-efficiency furnace models
Careful sealing and adjustment of ductwork for quiet, even heated air and proper airflow
Compliance with all local codes and building codes in your Zip Code
This is the kind of Furnace Work that keeps your system running at optimal performance for years instead of just “working for now.”
Types of Furnaces & Heating Systems We Install
Every house and building is different. We help you choose the furnace type and HVAC equipment that fits your needs, budget and fuel source.
Natural Gas Furnace & New Gas Furnace Options
Most Bay Area homeowners use a natural gas furnace. We install:
Standard and high-efficiency furnace models
Single-stage, two-stage and variable-speed home furnace systems
New Gas Furnace options that pair perfectly with your existing air conditioner or cooling system
We work with quality brands, including American Standard, Carrier, Lennox furnaces and other leading manufacturers, to give you a reliable furnace with the right heating capacity for your home.
Electric Furnace & Heat Pump System
No gas line? Prefer to reduce gas usage? We can install:
Electric furnace options for homes without gas
Heat pump system setups that provide both heating and cooling in one HVAC unit
Systems that integrate with your existing air furnace or Air Conditioning equipment
Heat pumps are a great way to enjoy energy savings and lower energy costs while keeping your home comfortable.
Propane Furnace & Oil Furnace Replacement
In some surrounding areas, homes still use propane furnace or oil furnace systems. We can:
Replace an old unit with a safer, more efficient new system
Help you evaluate different fuel types and furnace type options
Make sure gas leak risks, combustion gases and venting systems are all handled correctly
Whether you need a residential furnace or light commercial furnace system for business owners, we’ll recommend the right equipment for your space.
When to Replace Your Existing Furnace
Not sure if you should repair or replace your existing furnace? It may be time for new furnace installation if you notice:
Frequent repairs and rising repair costs
An old furnace that’s 15–20+ years old
Uneven temperatures and weak heated air
Unusual noises like banging, rattling or squealing
Increasing heating bills and energy costs
Visible rust, cracks or burn marks on the furnace setup
Our comfort consultants will inspect your furnace system, discuss the overall costs, and help you decide whether further repairs or a new unit is the smarter long-term move.
Understanding Furnace Efficiency & AFUE Ratings
When comparing furnace installation cost and models, you’ll see efficiency ratings like Annual Fuel Utilization Efficiency (AFUE).
A higher AFUE = more of your fuel turns into heated air instead of going up the flue pipe as waste.
A high-efficiency furnace typically has AFUE of 90–98% and may qualify for a tax credit or local incentives.
We’ll explain how AFUE, furnace type, and advanced features like variable-speed motors and programmable thermostat options affect comfort, energy efficiency and lifetime heating costs so you can make a smart Home Improvement decision.
