Cornerstone Air

About Cornerstone Air

Homeowners in Plano with an air conditioner blowing warm air or a furnace that will not light may come across Cornerstone Air. Few local outfits list as long a run: 16 years. The team is 10 people.

Central air conditioning repair is on the listing. Warm air from the vents, an outdoor unit that will not start, ice on the lines and water around the indoor unit are the usual reasons people call.

Most HVAC calls start with a room that is too hot or too cold, a system that runs constantly or a noise that was not there before. Describing what you notice and when it happens helps a technician narrow it down.

Low refrigerant usually means there is a leak somewhere, so it is fair to ask whether a repair will find and fix the leak or only recharge the system.

The hours, Monday 8:00 am to 6:00 pm; Tuesday to Friday all day, open as early as 8:00 am. Towns near Plano, like Richardson, Allen and Sachse, may or may not be covered.

To get a useful answer from Cornerstone Air, send photos of the labels on the indoor and outdoor units showing the brand, model and manufacture date. Ask for the scope, price and start date in writing before any equipment is ordered.
