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.

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.
Symptoms Worth a Service Call
- The thermostat calls for heat and nothing happens
- Banging, squealing or rattling from the furnace
- The blower won't stop running
- Cold air coming out of the vents
- The burners light, then shut off a few seconds later
What Moves the Price
- Night, weekend or holiday rates
- The furnace's age and brand, which affect parts availability
- The diagnostic or service call fee
- Whether the part is still under the manufacturer warranty
- Which part failed: a flame sensor costs far less than a control board or blower motor
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
- A diagnostic check
- Replacing the part that failed
- A test run through a full heating cycle
- A safety and combustion check
Texas Licensing and Efficiency Rules
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). A repair usually goes ahead without a permit, but the tech handling refrigerant must hold EPA 608 certification. Ask the company for its Texas license or registration number before the visit.
Before You Hire
- Check the filter, the thermostat batteries and the breaker first. Those three cause a surprising number of no-heat calls.
- Ask whether the diagnostic fee comes off the repair bill.
- Have the model and serial number from the furnace label handy. Parts get ordered faster.
