During the 30 years when I have installed the air conditioning, it has changed a lot: so much that, if not the property installed, it will not get the return of its investment. According to HVAC’s excellence, “industry estimates show that 70% of Hvacr equipment installed today have an inappropriate air flow, 67% have gained imperrubution and 70% of the systems are large . ” To solve and prevent these problems, CVC excellence said that “education should be the focal point of our industry”. The Texas Calefacting and Cooking star has frequented Houston, Cypress and Katy areas for several years. The air conditioning problems we found in these markets are air flows and inappropriate equipment that are poorly installed. Air conditioning is a measured science and we correct the problems we find measuring the air flow and the refrigerant load.
