We own a rental in Columbia and the HVAC suddenly died just as it was starting to heat up. We called three vendors for an analysis and quote to do either a repair or replacement of the entire system. Solutions was by far the least expensive option. Beyond that, their service was quick, to the point, efficient and thorough. We called them Wednesday, they went out to the house on Monday, and completed the entire job by Tuesday. We were shocked that they got it done so quickly. Keep in mind, they removed all of the old duct work and hardware and equipment, and installed the new ducts and hardware IN ONE DAY. We were given a selection of products to choose from, offered professional opinions and advice and consulted during and after the job on points of interest. What an outstanding team of professionals! Highly recommended.
