Pro Tech Air Conditioning and Heating

Pro Tech Air Conditioning and Heating maintains a 4.9-star average across 184 reviews, reflecting over a decade of continuous operation in the Las Vegas Valley. The company holds Arizona ROC license #335077 and operates 24 hours a day, every day of the year, serving residential and commercial clients across Las Vegas, Henderson, Summerlin, Green Valley, North Las Vegas, Southern Highlands, and portions of Northern Arizona. Owner John Nelson has built a team known for explaining diagnostic findings in detail while showing customers photos of the underlying issues, a practice multiple reviewers cite as transparency that distinguishes their service from competitors.

What separates Pro Tech Air from valley competitors is their systematic approach to desert-specific load calculations. Rather thandefaulting to standard sizing, their technicians determine precise heating and cooling requirements by evaluating square footage, insulation quality, window placement, and local climate extremes. This prevents the common problems of undersized systems unable to handle triple-digit summers or oversized units that short-cycle and fail to dehumidify properly. The company offers both residential service agreements and commercial facility management packages designed to maximize profit margins for property managers, with everything from routine maintenance to custom-designed installations using engineered specifications and approved equipment.

Customer reviews name several technicians who have become trusted household names. John Nelson fixed a difficult-to-diagnose problem on the coldest day of the year, arriving promptly and completing the work in a single visit. Gary Bressem walked a customer through after-service best practices to extend their AC unit's lifespan, while Alex handled a vent and duct cleaning job that left the customer reporting they could breathe better afterward. Property management firms maintaining portfolios exceeding 250 homes specifically credit the team's fair pricing and reliable scheduling as reasons for multi-year exclusive reliance.
