HVAC Repair Katy TX | Call Katy's Comfort A/C and Heating

Our maintenance service is designed to keep your system running efficiently and prevent costly breakdowns. We perform a comprehensive check, including cleaning components, inspecting electrical connections, checking refrigerant levels, and ensuring your thermostat is calibrated. For Katy homeowners, this proactive care is especially important to maintain cooling capacity during our hot summers and can help identify common local issues like minor refrigerant leaks early.

Yes, a loss of cooling capacity is a common symptom of a refrigerant leak, which we frequently diagnose in Katy homes. We start with a thorough inspection using specialized tools to locate the leak's source. Once found, we repair the leak according to manufacturer specifications, perform a vacuum test to ensure the system is sealed, and then recharge it with the correct amount of refrigerant. We always follow EPA guidelines for handling refrigerants and will explain the repair process and any warranty coverage clearly.

Signs of thermostat wiring issues can include your HVAC system not turning on, short cycling (frequent on/off cycles), or the display being blank. These problems are not uncommon in our area. For safety and to prevent further electrical issues, we recommend having a professional like our team diagnose it. We'll carefully inspect the wiring at your thermostat and at the HVAC unit itself, correct any loose or corroded connections, and ensure everything is communicating properly to restore reliable control of your home's temperature.
