Climate Considerations
San Antonio's climate is predominantly hot, with average summer temperatures reaching 90.0°F, but our winters can be unpredictable. With an average winter temperature of 52.5°F, HVAC systems often sit idle for long stretches, which can lead to issues like dust buildup or pilot light failure. When the temperature dips, your system needs to be ready to handle the transition from cooling to heating efficiently.
Furnace Services Tips
Schedule an annual furnace tune-up in the fall to ensure your system is ready before the first cold snap hits.
Change your air filters every 1 to 3 months to improve airflow and prevent your furnace from short cycling.
Always hire a licensed and insured technician to inspect your system if you notice a strange furnace smell or suspect a gas leak.
Keep the area around your furnace clear of debris and storage items to ensure proper ventilation and safety.
Install a programmable thermostat to optimize your energy efficiency and lower heating bills during shorter winter periods.
Frequently Asked Questions
How much does furnace repair or replacement cost?
Costs vary based on the complexity of the repair, the age of the unit, and whether you need parts or a full system replacement. Always request upfront pricing from a licensed contractor.
Why is my furnace blowing cold air?
This is often caused by a dirty flame sensor, a pilot light issue, or a thermostat setting error. If the problem persists, a professional furnace service is recommended.
Should I repair or replace my old furnace?
If your furnace is over 15 years old and requires expensive repairs, replacement is often more cost-effective and energy-efficient in the long run.
How long should a furnace last?
Most well-maintained furnaces last between 15 and 20 years. Signs of failure include rising energy bills, frequent repairs, and uneven heating.
What AFUE rating and size do I need for San Antonio?
For our climate, a mid-to-high efficiency furnace is ideal. Proper sizing is critical; an oversized unit will short cycle, while an undersized one will struggle to heat your home.
Is a cracked heat exchanger dangerous?
Yes, a cracked heat exchanger can leak carbon monoxide into your home. This is a serious safety hazard that requires an immediate inspection by a certified professional.
What is the difference between gas and electric furnaces?
Gas furnaces typically provide more intense heat and are often cheaper to operate, while electric furnaces are generally easier to install and carry no carbon monoxide risk.
How does furnace sizing affect my comfort?
An improperly sized furnace leads to inefficient operation, higher energy bills, and inconsistent temperatures throughout your living spaces.
What should I expect during a furnace installation?
A professional installation includes removing the old unit, sizing the ductwork, installing the new system, and performing a safety check to ensure optimal performance.
How can I lower my heating bills?
Upgrading to a high-efficiency furnace with a higher AFUE rating and maintaining your system with regular professional tune-ups can significantly reduce your monthly heating costs.
