Is Your Furnace Not Running Right? 

We’ll Fix It Before the Cold Sets In

Furnace can request a furnace repair contractor in San Antonio, TX, without notice. If you’re experiencing any of these common furnace problems, we are here to help:

Dirty Air Filters

Clogged filters restrict airflow, forcing your furnace to work harder and reducing efficiency. This can lead to overheating, poor heating, and higher energy bills. Let us clear the air and get your system running smoothly again.

Ignition/Pilot Light Problems

If your furnace isn’t igniting or you hear clicking sounds without a flame, it’s likely an issue with the ignitor or pilot light. We’ll pinpoint the cause and restore warmth to your home quickly.

Thermostat Malfunctions

Inconsistent temperatures or constant short cycling could indicate that your thermostat is reporting inaccurate readings or failing to signal the furnace. Our experts will fix or replace it to ensure consistent heating.

Blower Motor Failures

If the vents are not blowing warm air, the problem could be your blower motor. We will repair or replace it to restore comfort to your home.

Cracked Heat Exchanger

A broken heat exchanger is a safety risk and may even leak carbon monoxide into your house. We will check your system and fix the problem to keep your family or employees safe.
