Furnace Replacement & Installation
A new furnace should last two decades, so the sizing and the installation deserve more attention than the sticker on the cabinet. Oversized furnaces short cycle, overheat the ductwork, and leave the house uneven — a problem no brand name can fix.
Shepherd HVAC runs a load calculation on every replacement, checks the duct system it will feed, and gives you a written proposal with options. Comfort, reliability, and honest pricing, in that order.

What to Watch For
Signs It Is Time for a New Furnace
Replacement is usually the better value once these start stacking up.
The furnace is 15 or more years old
Older 80% AFUE equipment wastes a fifth of every heating dollar up the flue.
A cracked heat exchanger
This is a safety condition, and on most systems it means replacement rather than repair.
Rising gas bills
Efficiency losses show up on the bill long before the system fails outright.
Uneven heat between floors
Often a sizing or airflow mismatch that a properly designed replacement corrects.
Repeated repairs
Two or more service calls per heating season rarely pencils out against new equipment.
Loud operation
Single-stage blowers are noticeably louder than the variable-speed equipment available today.
How It Works
How We Handle Furnace Installation
- 1
Load calculation and duct review
We measure the home and evaluate static pressure and duct capacity so the new furnace is sized to the house rather than to whatever was there before.
- 2
Clear written options
Single-stage, two-stage, and modulating variable-speed choices with AFUE ratings, warranty terms, financing, and total installed price — all itemized.
- 3
Code-compliant installation
Permits pulled, venting and combustion air brought to current code, condensate handled correctly, gas piping and electrical connections verified.
- 4
Commissioning
We set gas pressure, measure temperature rise, confirm safety controls, register the warranty, and walk you through the new thermostat.
Pricing
What Affects the Cost
Installed price depends on the equipment tier and on what the house requires to support it.
Efficiency and staging
A 96% modulating furnace costs more than an 80% single-stage unit and delivers far steadier comfort.
Venting requirements
Moving from atmospheric to high-efficiency condensing venting means new PVC runs and a condensate drain.
Ductwork and plenum work
Transitions, returns, and sealing are common on older homes and directly affect performance.
Gas and electrical upgrades
Undersized gas lines or an old disconnect may need to be corrected.
Pairing with a new AC coil
Replacing furnace and coil together protects efficiency ratings and simplifies warranty coverage.
