Cornerstone Air

About Cornerstone Air

Based in Plano, TX, Cornerstone Air works as a central air conditioning repair service. A team of 10, the business has been operating for 16 years. During hot stretches in Plano, the most frequent repair calls involve iced-over coils, outdoor fans that will not spin, and water pooling near the indoor unit. Each symptom has several possible causes, and a repair visit narrows the list down with testing before any parts are ordered or replaced.

Common requests for central air conditioning repair include refrigerant leak detection, contactor replacement, AC not cooling diagnosis, short cycling problems and clogged condensate drain line.

Short cycling, rising humidity indoors, and water leaking near the furnace or air handler are common early signs that an air conditioning system has a problem. Describe exactly what the system is doing, such as blowing warm air or refusing to turn on, and note the thermostat setting and any displayed error codes. System age, part availability for the specific model, and whether the visit falls on evenings or weekends are the usual factors behind a repair quote.

Customers in Plano and nearby areas such as Richardson, Allen and Sachse can request a quote. Posted hours are Monday to Friday. Accepted payment methods include Cash, Check and Credit card. To get started, send Cornerstone Air a request on Fixerlane with the details of your project.
