This will be Legacy Air's 185th review and they still have 5 stars! That is quite impressive especially for a Vegas company.
I have rentals in town and have called them twice for Hvac issues on one of the houses. Mario didn't take any shortcuts and tried to rule out all possibilities before making a diagnosis. It's a big deal especially when the suspected problem is the AC compressor! Unfortunately it turned out to be the compressor. He was able to replace it at a fair price.
Just today Mario promptly fixed an issue with one of the furnaces in one of my rentals and was proactive about doing maintenance on the home's second furnace to prevent the same from happening even without me asking.
Don't hesitate to call Legacy if you have any type of Hvac issues. Ask for Mario.
