Frequently asked in San Antonio

What do I do if my furnace won't turn on in San Antonio?

When your furnace in San Antonio won't turn on, the first step a licensed pro takes is checking the circuit breaker. They'll then inspect the thermostat settings and ensure it's calling for heat. If those are fine, they'll move on to checking the furnace’s main power switch and the ignitor. Sometimes, a tripped safety switch can prevent startup. The specialist will explain what they find and the steps needed to get it running again.

Why is my furnace making a loud banging noise?

A loud banging noise from your furnace often indicates a problem with the heat exchanger or the blower assembly. The crew that comes out will check for debris or obstructions in the blower housing. They’ll also inspect the ductwork for loose connections that might be causing air pressure issues. Sometimes, this noise can be related to the ignition sequence. The technician will pinpoint the exact cause and explain your repair options.

What's involved in a furnace tune-up in San Antonio?

A furnace tune-up in San Antonio involves a thorough inspection and cleaning of your system. The technician will check the burner assembly, clean the flame sensor, and inspect the heat exchanger for cracks. They'll also test the gas pressure and calibrate the thermostat. Lubricating moving parts and checking electrical connections are part of the service. This preventative maintenance helps ensure your system runs efficiently and safely.

How do I know if my furnace needs to be replaced?

You might need a furnace replacement if the unit is old and frequently breaking down. If repairs are becoming increasingly expensive or the system is no longer heating your home effectively, it's time to consider replacement. The specialist who comes out can assess your system's condition and provide an honest recommendation. They’ll discuss energy efficiency improvements with a new unit.

Why is my furnace not blowing hot air?

If your furnace isn't blowing hot air, the licensed pro will first check the thermostat setting to ensure it's on the 'heat' mode. They'll then inspect the ignitor and the pilot light to confirm the burners are igniting. The technician will also check the fan and blower motor to make sure air is circulating. Sometimes, a clogged air filter can restrict airflow. They will identify the issue and explain the necessary fix.

What's the difference between a furnace and an HVAC system?

A furnace is specifically designed to provide heat, typically by burning fuel like natural gas or oil. An HVAC (Heating, Ventilation, and Air Conditioning) system is a broader term that encompasses heating, cooling, and air quality management. So, a furnace is a component of a larger HVAC system. The pros can discuss your home's specific heating needs.

Can I fix my furnace myself?

While some minor issues like changing an air filter can be handled by a homeowner, complex furnace repairs are best left to licensed pros. Working with gas lines or electrical components carries significant safety risks. The technician who comes out has the training and tools to safely diagnose and repair your system. They'll ensure the repair is done correctly and safely.
