Amarillo Weather and HVAC Load
NOAA's 1991-2020 climate normals put Amarillo at 4,283 heating degree days and 1,347 cooling degree days per year. Heating is the bigger job here, and furnaces and heat pumps in Amarillo put in far more hours than the air conditioner. A normal year brings 117 nights at or below freezing and 82 days over 90°F. Snowfall averages about 17 inches. For a 2,000 sq ft house, this climate points to a heating load somewhere near 55,000 BTU/h. Treat that as a starting number. A Manual J calculation will move it up or down based on insulation and windows.
| Heating degree days / year | 4,283 |
|---|---|
| Cooling degree days / year | 1,347 |
| Nights at or below 32°F | 117 |
| Days above 90°F | 82 |

Amarillo Housing Stock
Half the homes in Amarillo were built before 1972 (Census ACS median), so the typical house is about 54 years old. A lot of these homes are on their second or third system by now. The ductwork is usually original, and leaky joints are common. Amarillo has roughly 47,000 owner-occupied homes, or 59.6% of households. Homes here have a median value of $186,800 and households a median income of $62,469. Those two numbers drive the labor adjustment in our estimate.
Randall County had 34 hail days and 33 days with damaging thunderstorm winds from 2020 through 2025, according to NOAA storm records. The largest hail reported was 2.75 inches across. Hail flattens the thin aluminum fins on condenser coils and cuts airflow. After a big storm, take a look at the outdoor unit; homeowners insurance often covers the damage. Randall County also had 3 tornado days in that period.
When Replacement Makes Sense
- Gas or electric bills keep climbing even though usage hasn't changed
- The furnace is 15 to 20 years old or more
- Some rooms stay cold, the burner short-cycles, or the ignitor keeps failing
- A repair quote runs past a third of the cost of a new unit
What Moves the Price
- BTU size, which should come from a Manual J load calculation
- AFUE rating: a basic 80% unit vs. a 96% condensing furnace
- Condition of the existing ductwork and any changes it needs
- Single-stage, two-stage or modulating gas valve
- Permit and inspection fees, which the local building department sets
- New PVC venting if you move to a condensing model
We lowered the national figures about 4% for Amarillo using local income, home values and the equipment size this climate needs. Real bids can still come in outside the range, so collect three written quotes.
What the Quote Should Cover
- Removing and hauling away the old furnace
- The new furnace, filter rack and thermostat wiring
- Gas line and vent connections
- The permit and the manufacturer warranty registration
- Combustion and safety tests
Texas Permits, Efficiency Rules and Rebates
Texas is in the DOE's Southeast region, where new split central air conditioners need at least 14.3 SEER2 (13.8 SEER2 for systems of 45,000 BTU/h and up). Equipment replacements in Amarillo generally need a mechanical permit, and a reputable contractor will pull it for you. Ask for their Texas license or registration number and a certificate of insurance with the quote. The federal 25C tax credit ended for equipment installed after December 31, 2025, so incentives now come mostly from utilities and state programs. Check your electric and gas utility's rebate page before you pick equipment.
Before You Hire
- Ask for the Manual J load calculation in writing. Oversized furnaces are the most common mistake we see.
- Make sure all three quotes are for the same AFUE and staging, or you can't compare them.
- Look up utility rebates on 95%+ AFUE units before you buy.

Furnace Replacement Questions from Amarillo Homeowners
How much is furnace replacement in Amarillo?
Plan on $3,100 to $7,500, with most jobs near $5,500. Equipment efficiency, house size and the condition of the ducts and wiring decide where your quote falls.
When is the best time to schedule furnace replacement in Amarillo?
Between late spring and early fall. Amarillo averages 117 freezing nights a year, and heating calls spike from November through February.
Is a high-efficiency furnace worth it?
In cold climates, a 95%+ AFUE furnace usually earns back the price difference in lower gas bills. Where winters are mild, the payback can take a very long time.
How long does a furnace replacement take?
A straight swap is usually done in one day, somewhere between 4 and 10 hours. Moving to a condensing furnace with new PVC venting can add a few more.
