Our take: It carries the highest star rating here, but on fewer reviews than the others, which is why it sits lower. Reviewers like its replacement work and the way calls are answered personally.

Claim this spot › How the scorecards work
Every number on this page comes from public Google data as of October 2026, not from opinion or payment. Rating is the live Google star average. Review volume shows how many customers have rated each company, compared with other Las Cruces HVAC contractors we looked at. Confidence weighs the rating by that volume, so a 4.9 from more than a thousand people carries more weight than a 5.0 from a few. Recency reflects how recently customers are still reviewing. No business can pay to change these numbers.
What shapes an HVAC bill in Las Cruces
We could not source dependable local price ranges for this page, so we are printing none. The bill depends on the equipment type, such as central air, a mini-split or a refrigerated conversion, on ductwork condition, on whether an old evaporative cooler must come out, and on the warranty. Ask each company to itemize equipment, labor and any duct repair in writing, and say whether financing is available.
Heating and cooling across the Mesilla area
These companies work from Picacho Ave, N Seventeenth St, Amador Ave and Saturn Cir. Aircon’s site lists Dona Ana, Mesilla, Hatch, Rincon and Mesilla Park among its service areas, and Sun City says it serves Dona Ana and surrounding areas. Searching for HVAC near me? Each listing shows a live phone number so you can ask about same-day availability.
What to ask before you sign an HVAC quote
- Is the quote for repair or full replacement, and why?
- Which brand and model are you proposing, and is the warranty on parts, labor or both?
- Do you charge a diagnostic fee, and is it credited if I go ahead?
- Does the job include ductwork inspection or repair?
- Can you service my existing mini-split or evaporative cooler?
- Are financing options available?
Frequently asked questions
Can a Las Cruces HVAC company replace an evaporative cooler with refrigerated air?
Yes, reviewers describe exactly that. Aircon Heating & Cooling converted a 1970s home in a few days, and a Starrett’s customer reports switching from an evaporative cooler to refrigerated air at a good price. A Sun City customer also had old swamp cooler ductwork removed from an attic.
Which of these companies services mini-split systems?
Reviews show mini-split work at Aire Serv of Southern New Mexico (twice-yearly upkeep), Aircon Heating & Cooling (ductless installs) and Starrett’s (a replacement). Ask whichever you choose about the exact brand you own.
Do any of them also handle plumbing or water heaters?
Sun City Plumbing & Heating lists plumbing, water heaters and water softeners alongside HVAC. Starrett’s lists tankless water heaters, and a reviewer had one installed on a Saturday.
Who offers financing or a written workmanship warranty?
Starrett’s site lists financing and a one-year workmanship warranty, and Aircon’s site mentions warranty coverage on Carrier products. Confirm the terms in writing before you agree.
Where to begin
Sun City Plumbing & Heating is the default for sheer track record and big installs, with Aire Serv a strong choice for maintenance plans. If a company has told you a whole system must go, a second opinion from Aircon is easy to justify. Whoever you pick, get the equipment, labor and warranty written down.
