I contacted Black Mountain Air because of the GREAT reviews mentioned on YELP. This company is solid. Todd came over to check out our vent and air conditioning system after I was quoted thousands$$$ of repairs needed to be done ( I will not mention the competitors name) I called upon Black Mountain to give me a second opinion. At no charge, Todd found nothing wrong and was not selling me on product I didn't need. I told him what the competitor told me and he laughed. Simply put, he said to just call me when something goes wrong. Beware of the companies out there that will upsell you airconditioning units and services you don't need. Look to Black Mountain as your "Go to" company as they are honest and solution oriented.
