Gavin Mechanical Services | Newtown Square HVAC Repair for Furnace & AC Issues

First, check your thermostat settings and ensure the furnace's power switch is on. If it's still not igniting, it's best to call us. In Newtown Square, ignition failures are often due to a faulty flame sensor, ignitor, or gas valve—issues that require a professional HVAC technician for safe, proper repair. We offer prompt service to get your heat restored quickly.

Signs include reduced cooling, ice on the evaporator coils, and hissing sounds. For Newtown Square homes, refrigerant leaks are a frequent cause of AC inefficiency. We perform a thorough leak detection test, locate the source, and make the necessary repair before recharging your system to the manufacturer's exact specifications, ensuring optimal performance and longevity.

Regularly replace your air filter to ensure proper airflow, which reduces strain on your system. Keep the area around your outdoor AC unit clear of debris. For preventative care specific to our local climate, schedule an annual tune-up with us. We'll clean critical components like the flame sensor, check refrigerant levels, and identify small issues before they lead to major failures like ignition problems or leaks.
