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. Our technicians identify warning signs early to help save time and avoid larger repairs, including when your heater is struggling to maintain a safe indoor temperature. If you’re experiencing any of these common furnace problems, such as strange smells, lukewarm air, possible gas leaks, or cracked heat exchangers, 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 in a gas furnace or boiler 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, and this is essential to address immediately for safety.
