New gas furnace installation — since 2010
Fresh Air Heating & Air installs new gas furnaces for Sacramento-area homes — whether you are building new, adding on, remodeling, or adding central heat where none existed before. Licensed, insured, and trusted with over 900 systems installed. Free estimates, honest sizing, and complete installations including gas line work, venting, and permits.
Not every furnace job is a replacement. Many Sacramento homeowners need a furnace installed where one has never existed — or where the existing heating system is something other than a forced-air furnace. Fresh Air handles the full scope, from gas line to thermostat.
Building a new home in Sacramento, Elk Grove, Folsom, or Roseville? Fresh Air works with builders and homeowners to design and install complete heating systems. We size the furnace with a Manual J load calculation based on your plans, coordinate with your GC, pull permits, and deliver a turnkey installation that passes inspection the first time.
Adding square footage often means your existing furnace can not handle the extra load — or the new space needs its own system. We install furnaces sized specifically for addition projects, with new ductwork, gas line extensions, and independent zoning so the new space stays comfortable without overtaxing the original system.
Many older Sacramento homes rely on wall furnaces, floor heaters, baseboard electric, wood stoves, or radiant ceiling heat. Converting to a modern forced-air gas furnace transforms comfort, air quality, and home value. We handle gas line runs, ductwork design, thermostat wiring, and every detail of the conversion.
A major remodel is the ideal time to install central heat if your home does not already have it. With walls open and access available, running ductwork, gas lines, and electrical is far easier and less expensive. Fresh Air coordinates with your remodeling contractor from the rough-in phase through trim-out and startup.
Detached garages, workshops, and accessory dwelling units (ADUs) often need their own heating. We install appropriately sized furnaces — or mini-split heat pumps for smaller spaces — with independent gas lines, venting, and controls. Sacramento ADU regulations allow separate HVAC systems; we can advise on code requirements.
AFUE (Annual Fuel Utilization Efficiency) measures how efficiently a furnace converts natural gas into usable heat. For a new installation — where you are not locked into existing venting — you have complete freedom to choose the efficiency level that best fits your budget and long-term savings goals.
Single-stage, single-speed blower. Vents through a metal flue pipe to the roof. Lowest upfront equipment cost — typically $4,000-$6,000 installed with gas line and venting. Best for budget-conscious projects, rentals, or homes where the furnace runs relatively few hours per year. Note: a new metal flue to the roof may add cost compared to side-wall PVC venting.
Two-stage gas valve with a high-efficiency ECM blower motor. Uses sealed combustion and PVC venting through a side wall — no roof penetration needed. Operates on low stage about 70-80% of the time for quiet, even heat. Cost: $5,000-$8,000 installed. The sweet spot for most Sacramento homeowners installing a new furnace from scratch.
Modulating gas valve with a variable-speed ECM blower. Adjusts heat output in tiny increments for near-perfect temperature control. Whisper-quiet, maximum efficiency, and best comfort. Requires PVC venting and a condensate drain. Cost: $7,000-$12,000+. Ideal for comfort-focused homeowners who plan to stay long-term.
With a new installation, you have the advantage of getting the sizing exactly right from day one. There is no old, oversized furnace to match — we calculate the correct BTU requirement for your specific home. Many contractors default to rules of thumb like "X BTUs per square foot," but that approach nearly always results in an oversized furnace that short-cycles, wastes gas, and creates uncomfortable temperature swings.
Fresh Air performs a Manual J load calculation for every new furnace installation. This industry-standard calculation accounts for your home's specific heat loss based on square footage, ceiling height, insulation levels (walls, attic, floor), window area and orientation, air leakage, number of occupants, and even shade from trees or neighboring structures.
The output is a precise BTU-per-hour heating requirement. We then select a furnace whose capacity matches that requirement. Correct sizing means the furnace runs longer, steadier cycles that use less gas, distribute heat more evenly, and put less wear on components. It is the single most important factor in a successful installation — and one Fresh Air gets right every time.
The process starts with a free in-home estimate. A Fresh Air technician visits your home, assesses the installation site, takes measurements, and discusses your heating needs and budget. We evaluate gas line proximity and capacity, venting options (roof vs. side wall), electrical requirements, thermostat location, and ductwork feasibility. If you are working with a builder or GC, we coordinate with them from the start.
We present furnace options at different AFUE levels and price points. Because this is a new installation — not a replacement — we discuss venting options in detail. A 90%+ AFUE furnace uses PVC side-wall venting, which avoids a new roof penetration. An 80% furnace requires a metal flue to the roof. The cost difference between these two approaches often narrows the price gap between standard and high-efficiency for new installs.
We pull all required permits — mechanical, gas, and electrical — and schedule inspections. On installation day, our crew arrives on time with the new furnace, materials, and all necessary safety equipment. We protect floors and work areas, run gas lines (if needed), install the furnace with proper venting and condensate drainage, wire the thermostat, and commission the system. We test gas pressure, combustion, airflow, and temperature rise — and walk you through thermostat operation before we leave.
Fresh Air serves Sacramento, Elk Grove, Folsom, Roseville, Rocklin, Citrus Heights, Rancho Cordova, Davis, and all surrounding communities. With 900+ installs and a 5-star reputation, we are the furnace installation contractor Sacramento homeowners trust for new construction, additions, and conversions.
Absolutely. Fresh Air installs gas furnaces in homes that have never had central heating — whether it is new construction, an addition, a remodel, or a home previously heated by wall heaters, baseboard electric, or a wood stove. We handle gas line from meter to furnace, electrical, venting, condensate drain, thermostat wiring, and ductwork connection. Free estimate includes a complete site assessment.
New furnace installation typically starts around $3,997 and commonly ranges from $4,000 to $12,000 depending on scope. A straightforward install with existing gas and ductwork on the lower end. New gas line runs, new venting, new wiring, or new ductwork add to the total. Permits are additional. During your free estimate we provide a detailed fixed-price scope of work.
Yes — a mechanical permit is required for any new furnace installation in Sacramento and surrounding jurisdictions. Fresh Air pulls permits as part of the job and schedules the inspection. We do not cut corners on permitting — it protects your safety, your insurance, and your home's resale value.
For a brand-new installation, we recommend 95-96% AFUE two-stage. Since you are not reusing existing venting, a high-efficiency furnace with PVC side-wall venting often costs about the same as an 80% furnace needing a new metal flue to the roof. A 90%+ unit qualifies for utility rebates and reduces monthly gas bills. We review the payback math during your estimate.
A new furnace installation where ductwork already exists typically takes 1-2 days. If the job includes a new gas line run, new venting, new thermostat wiring, or new ductwork, plan on 2-4 days. Permits and inspection scheduling add time before and after installation. We provide a clear timeline during your estimate.
Yes — and it is often more cost-effective to install both a furnace and AC at the same time. The indoor evaporator coil mounts on top of the furnace, and the shared blower, electrical, and thermostat save on labor. If you are building new or doing a major remodel, installing both now avoids the disruption and cost of adding AC later. Fresh Air can provide a combined quote.
