“Incredible experience with Western Mechanical! From the initial phone call, their communication was courteous, prompt, and completely professional. The technicians arrived right on time, were very respectful of our space, and clearly knew exactly what they were doing. They diagnosed our cooling issue quickly, completed the maintenance without leaving any mess behind, and had everything operating at peak performance. It’s so refreshing to work with an honest, reliable team that takes true pride in their craftsmanship. Couldn’t be happier with the service!”

“Im elderly and was having trouble with an industrial HVAC system. They came repaired and fixed it. Also gave me information on heating-air repair and services so i could maintain the unit. wisely. Leaving my first review because they did such a great job!! Thank You”

“I've NEVER given a 1 Star rating for any business until now. It's just not in my nature to go negative. However, I'm incredulous that they charged me $640 to come out to my office to give me a QUOTE to fix my A/C unit. Nothing was even done or repaired! To be fair, they gave me a head's up about the extra trip charge and an hourly rate. BUT $640 for a diagnosis?! That's ridiculous! To make matters worse, they then quoted me $21,006.49 to replace my entire unit. They didn't even offer to apply the $640 towards the replacement fee. Needless to say, I got 2 other quotes and BOTH were $5,000 less than Western Mechanical! One quote was done at no charge and the other was only $100 (and that was applied towards the replacement fee). Unless you're rich, stay away from this place!”

“Do your research and get a licensed ethical contracting company. Do not recommend these guys.”
