She requested a quote for an extra A/C unit for her home, because the existing unit was not cooling the house in the summer. Before Climatrol quoted the cost for an extra unit we checked the existing system, checked the duct work sizing, and did a total static pressure system test. Climatorl found a few problems with the existing unit and made the necessary repairs. There was no need for an extra unit, charged the customer $2,200 and saved Mary thousands of dollars.
