What to Check First
Before you call a repairman, there are some easy things you can check yourself. First, look at your thermostat to make sure it’s set on “auto”. The fan will run only when the furnace is heating the air when set the thermostat is set to “auto.” Whereas, the fan will run continuously when it is set to “on,” even when the furnace isn’t heating the air.
Typically, a dirty air filter can cause many problems, including your furnace blowing cold air. Too much dirt in your filter will clog it, restricting the flow of air. Restricted airflow can cause overheating thereby triggering a safety switch turning your furnace off. How often you should change your air filter depends on several factors. These include the number of people/pets in your household as well as the type of air filter you use. Most manufacturers recommend a minimum of changing the air filter every 30-60 days.
Finally, check your ductwork. Even small cracks in your ducts may cause cold air to mix with the warm air. While larger cracks will result in complete loss of warm air. In general, most ductwork lasts between 10-15 years before it begins to deteriorate. If your ductwork is nearing that age you may want to consider replacing it.
Although you may have a gas furnace, part of your system is electrical. Your thermostat as well as ignition, valve and blower motor all require electricity. Therefore, something as simple as a tripped breaker could be causing cold air blowing out your vents into your home.
Therefore, check to make sure you don’t have a tripped breaker inside your electrical panel. Generally, when you’re running too many appliances, the breaker trips, stopping the flow of electricity. Even if your furnace runs on electricity, it’ll have a separate circuit breaker. Thus, the fan could run without the furnace operating.
One more thing to check is your pilot light. Older gas furnaces have them and it’s important to check to make sure it’s still lit. There could be several reasons why your pilot light goes out including drafts, dirty orifice, or bad thermocouple. Whereas if you have a newer gas furnace, your flame sensor could be dirty. When the flame sensor becomes coated with dust, it cannot correctly take readings and will shut down the furnace.
Time to Call a Repairman
If you’ve checked all you can and your furnace is still blowing cold air, it’s time to call a repairman. There are some things best left to the professionals no matter how easy YouTube makes it look. Whether you have a gas or electric system, there are dangers involved in trying to repair it yourself. The cost of hiring a repairman is offset by peace of mind for a quality repair by a certified technician.
Nevertheless, if your HVAC system is over 10 years old, you may want to consider upgrading to a new system. Most homeowners put off upgrading their heating system for as long as possible, often waiting for complete failure. However, this normally ends up costing more because as performance declines, monthly energy bills rise.
Although new HVAC systems are expensive, Aspire Heating & Cooling offers financing options to make them affordable. We are a primary lender providing favorable interest rates and extended repayment terms. For as low as $60 per month, you can have a brand new HVAC system.
