Santa Teresa, NM: what's different here
Santa Teresa sits in Doña Ana County, New Mexico, about 13 miles and roughly 19 minutes by car from El Paso via the main highway. The desert climate is hot and dry, with El Paso-area summer heat commonly reaching triple digits, which increases cooling demand and system runtime. Low humidity and dust are common HVAC maintenance concerns in the area, where annual precipitation averages around 9 inches.
What does evaporator coil replacement involve?
A professional HVAC contractor replaces the indoor coil, reclaims and recharges the refrigerant, and completes brazing, vacuum, and leak-check work. This is not a do-it-yourself job because of the refrigerant handling involved.
How long do AC evaporator coils last?
AC evaporator coils typically last 10 to 15 years with proper maintenance. Dust is a common maintenance concern in the El Paso area, which averages only about 9 inches of rain a year.
Who is licensed to do HVAC work in New Mexico?
In New Mexico, HVAC and mechanical work is licensed statewide by the Construction Industries Division. Contractors must meet classification and exam requirements for the specific work performed. Applicants generally need four years of qualifying mechanical experience and must pass the required exams.
Should I repair or replace the coil?
If your system is near the 10 to 15 year coil lifespan, compare the out-of-warranty replacement cost of $2,500 to $4,500+ against a full system replacement. Ask the pro for a written quote covering access, labor, and refrigerant work before deciding.
What to do next
- Ask the pro for a written quote that breaks out access, labor, and refrigerant work.
- Ask whether your unit is still under warranty, since that changes the cost by up to $2,000 or more.
- Verify the contractor's mechanical classification with the New Mexico Construction Industries Division before work starts.
- Ask for proof of licence and insurance before the 4 to 8 hour job begins.
- Call (915) 286-7051 or email [email protected] for a free quote from an independent, licensed, insured AC repair contractor.
