Is Your Furnace Not Heating Right?
Call Us For A Solution You Can Trust
Comfort quickly gives way to annoyance when your furnace breaks down, especially given San Antonio’s extreme temperature swings. Here’s what might be going wrong:
Poor Ductwork & Airflow
If your furnace is heating unevenly or short-cycling, leaky ducts or blocked vents might be the culprit. We’ll seal up those leaks and restore proper airflow, so your furnace works efficiently.
Incorrect Furnace Sizing
If your furnace is struggling to heat your home, it might be the wrong size. We will make sure your furnace fits your home perfectly, ensuring consistent warmth without wasting energy.
Ventilation & Drainage Issues
Clogged condensate drains or blocked exhaust pipes can cause your furnace to shut down unexpectedly. We will make sure your furnace vents are cleaned properly to keep it running safely and efficiently.
Electrical Wiring Faults
Loose wires or faulty connections can cause your furnace to fail randomly or not start at all. Our furnace installation experts in San Antonio, TX, install wiring so your furnace runs smoothly and reliably every time you need it.
Faulty Thermostat/Sensors
If your thermostat is reading incorrectly, your furnace might not heat effectively. We will recalibrate your thermostat and clean the sensors, so your furnace delivers accurate temperature control every time.
