The techs at Lone Star Pro Services hope clients never see, smell, or even think about the results of their work. That's because the outfit's chief concern is residential air quality—something that homeowners don't notice until an air conditioner, furnace, or ventilation system fails. At six locations nationwide including three in the state of Texas, talented Lone Star technicians handle any issue pertaining to the HVAC system, such as dusty air ducts, dips in energy efficiency, or dryer vents clogged by socks on the lam.
