Roswell Weather and HVAC Load
NOAA's 1991-2020 climate normals put Roswell at 3,611 heating degree days and 1,596 cooling degree days per year. Heating is the bigger job here, and furnaces and heat pumps in Roswell put in far more hours than the air conditioner. A normal year brings 115 nights at or below freezing and 90 days over 90°F. Snowfall averages about 10 inches. For a 2,000 sq ft house, this climate points to a heating load somewhere near 50,000 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 | 3,611 |
|---|---|
| Cooling degree days / year | 1,596 |
| Nights at or below 32°F | 115 |
| Days above 90°F | 90 |
| Average low / high | 43.3°F / 75.5°F |
Roswell Housing Stock
Census figures put the median build year in Roswell at 1968, so a typical house here has about 58 years on it. A lot of these homes are on their second or third system by now. The ductwork is usually original, and leaky joints are common. About 12,000 households here own their home, 66.4% of the occupied total. Homes here have a median value of $139,200 and households a median income of $50,294. Those two numbers drive the labor adjustment in our estimate.
Between 2020 and 2025, NOAA's Storm Events Database logged 21 hail days and 28 days with damaging thunderstorm winds in Chaves County. The largest hail reported was 3 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. Chaves County also had 3 tornado days in that period.

New Mexico Permits, Efficiency Rules and Rebates
New Mexico is in the DOE's Southwest 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). The Southwest also sets a minimum EER2, which measures efficiency at peak heat. Equipment replacements in Roswell generally need a mechanical permit, and a reputable contractor will pull it for you. Ask for their New Mexico 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 your gas or oil company about rebates on condensing boilers.
- For a steam system, hire a contractor who works on steam regularly.
- A combi boiler frees up space and replaces your water heater.
