Frequently Asked Questions
What factors influence the cost of furnace repair or replacement?
Costs are determined by the complexity of the repair, the age of the unit, the cost of parts, and whether you are opting for a full system replacement which includes labor and equipment size.
Why is my furnace blowing cold air or short cycling?
This is often caused by a dirty air filter, a faulty flame sensor, or a thermostat issue. Short cycling can also indicate an oversized unit or airflow problems.
How do I decide between furnace repair or replacement?
If your furnace is over 15 years old and requires frequent, expensive repairs, replacement is often more cost-effective and provides better energy efficiency.
What is the typical lifespan of a furnace and what are the warning signs of failure?
Most furnaces last 15-20 years. Warning signs include rising energy bills, uneven heating, strange noises, or yellow flames instead of blue.
What AFUE rating and size should I choose for the O'Fallon climate?
For our climate, a furnace with an AFUE rating of 90% or higher is recommended for efficiency. Proper sizing must be calculated based on your home's square footage and insulation.
What are the safety risks associated with a cracked heat exchanger?
A cracked heat exchanger can leak carbon monoxide into your home, which is a serious health hazard. Professional inspections are vital for detecting these cracks early.
How do gas furnaces compare to electric furnaces?
Gas furnaces often provide hotter air and lower operating costs in our climate, while electric furnaces are generally cheaper to install and require less maintenance.
How does proper furnace sizing affect my comfort and utility bills?
An oversized furnace will short cycle and cause uneven temperatures, while an undersized unit will run constantly without reaching your desired temperature, both driving up bills.
What should I expect during a professional furnace installation?
A professional installation involves removing the old unit, modifying ductwork if necessary, installing the new system, testing safety controls, and ensuring proper airflow.
How can I lower my heating bills with a new high-efficiency furnace?
Upgrading to a high-efficiency model reduces fuel waste, and when paired with a programmable thermostat, you can significantly decrease your monthly energy consumption.
