Lex Air Conditioning and Heating: Qualified HVAC Repair Serving Plano, TX 75074

These are common issues in our Texas climate. Short cycling, where your AC turns on and off too frequently, or a frozen evaporator coil often point to problems like low refrigerant, a dirty air filter, or airflow restrictions. Lex's technicians are familiar with these Plano-specific challenges. We'll diagnose the root cause—whether it's a simple fix like changing a filter or a more complex refrigerant issue—and provide a clear explanation and solution to restore efficient cooling and prevent further damage to your system.

Yes, we provide comprehensive home services for Plano residents. While our roots are in HVAC, our certified technicians are also equipped to handle urgent plumbing repairs like burst pipes or clogged drains, and electrical issues such as faulty wiring or breaker problems. As a family-owned business, we understand that emergencies don't wait, and we aim to be a reliable, single-point contact for your home's essential systems, day or night.

Having served the area since the 1980s, our team has deep knowledge of the HVAC, plumbing, and electrical systems found in many Plano homes. We understand how older systems interact and the common wear-and-tear issues they face. This experience allows us to accurately diagnose problems, recommend durable repairs or appropriate modern upgrades—like high-efficiency AC units or tankless water heaters—and ensure new installations integrate properly with your home's existing infrastructure.
