Is Your Furnace Showing Signs of Trouble?

Before a heating system fails completely, it often gives off early warning signs. You might hear odd noises, feel cold air from the vents, or notice rising energy bills. Gas furnaces, heat pumps, and electric heaters can all develop problems with ignition systems, blower motors, clogged filters, or heat exchangers. If ignored, these issues can cause your system to stop producing warm air or even become unsafe.

Our San Antonio HVAC company repairs gas and electric furnaces, heat pumps, and ductless mini splits. We find problems early, explain every fix clearly, and perform preventative maintenance that helps reduce energy use and keeps your home comfortable through the colder months.

Questions About Furnace Repair in San Antonio

Why is my furnace blowing cold air?

A dirty air filter, ignition problem, or thermostat issue can stop your heating system from producing warm air. Our HVAC technicians inspect the blower motor, gas valve, and electrical components to fix the problem quickly.

What causes strange smells when I turn on my furnace?

Dust buildup, clogged filters, or electrical issues can cause odors when your furnace starts. Regular heating maintenance improves air quality and keeps your system safe.

How do I know if my blower motor is failing?

Weak airflow, loud noise, or frequent shutdowns usually mean the blower motor is wearing out. Replacing it restores proper airflow and reduces strain on the rest of your HVAC system.

What does a cracked heat exchanger mean for my furnace?

A cracked heat exchanger can leak carbon monoxide and reduce system efficiency. We inspect and replace damaged components to maintain safety and energy performance.

How often should I have my furnace serviced?

Schedule maintenance once a year before winter begins. Routine tune ups lower energy bills, improve heating efficiency, and prevent expensive furnace repairs.

Can regular filter changes prevent furnace problems?

Yes. Clean filters keep airflow steady, reduce strain on equipment, and help maintain comfortable room temperatures.

Do you install new furnaces if mine can’t be fixed?

Yes. We install high-efficiency furnaces, heat pumps, and ductless mini splits with upfront pricing and flexible financing for homeowners in San Antonio, TX.
