I called about an issue with my AC and was blown away by how quickly help arrived — he showed up within 30 minutes of my initial call! Not only was he incredibly professional and friendly, but he also quickly diagnosed problems caused by a previous technician and had everything fixed within the hour. The price was extremely reasonable, especially considering the fast response and quality of work. I’m so grateful for his honesty, efficiency, and skill. I won’t hesitate to call again in the future — highly recommend! See more See less

Absolutely recommend, 10 stars!! We recently moved into a new house and had trouble with our hot water heater immediately. I went through about 30 phone calls with a lot of people who just couldn’t or wouldn’t help. Finally, Al from Big Country Mechanical got the referral and instantly we had open lines of communication and were being assisted! He came right out to look at everything, assessed our problem and had an entire new water heater installed the next day. Not to mention, the install took him maybe an hour at most, talk about efficiency! I would recommend them for any job you need!! See more See less
