Steve Finley came out to compete for a job at my home regarding the failure of my geothermal Air Conditioning Unit which put the tenants in my Houston Rental without Air Conditioning during the tail end of a very hot summer. Steve provided the most conscientious estimate considering my needs. His price was also the highest, and considerably higher than all other estimates. When I looked into the matter, Air Tech was providing me a 5 ton unit that would barely fit in my closet, with a 10 year warranty manufactured out of industry leading materials; where the leading competitor was offering a 3.5 ton unit with a 3 year warranty with the cheapest possible compliant materials, and the leading competitor refused to consider installation of any other unit for my closet claiming that it was not possible for a 5 ton unit to fit. Of course, paying over $13,000 for an AC unit is hard to digest, so I asked for and received a courtesy discount. Boy am I glad that I chose Air Tech, and I'm glad that they provided the discount. When the initial unit arrived it wouldn't fit in my closet without turning the unit sideways because of a valve on top of a building supply line that interfered with the installation. Rather than install the unit sideways, which would have made it nearly impossible to access for maintenance, AIR TECH attempted to get permission from the building engineer in order to re-orient the valve. My condo association denied the permission, so AIR TECH, put in a RUSH order on a Brand new unit of Better quality that had to be custom manufactured for my space. Air Tech paid for the RUSH fee as well as gave me the better quality model which was custom designed at the vendor factory at the original agreed price. I give them an A on price for this reason. Despite Air Tech's accommodation, my tenants were very unhappy to go about 2 additional weeks without Air Conditioning so Air Tech provided them with portable units to hold them over until the job could be completed. Houston in the middle of October can get hot. One of the most important things that a customer wants from a vendor is honesty and quality. These guys are truly STAND UP. Steve profusely apologized for making an honest mistake and the owner of the firm personally handled my installation (he personally did the work) and I am so happy with their integrity that I rate them as the very best firm I've ever used from Angies List. If you have anxiety because vendors will try to pull a wool over your eyes to take advantage of your lack of knowledge then YOU MUST consider hiring this firm even if it costs a little bit more to do so. They have 10 stars from me for this job, but Angies List only lets me give them 5.
