As the temperatures begin to drop, you might look forward to walking into the warmth of your Louisiana home. But what do you do if your heating system is only blowing cold air? It may feel like the end of the world, but there are a few common causes of the problem that can be fixed.
Surgi’s Heating, Cooling & Plumbing aims to keep our New Orleans residents comfortable year-round. A heatless heater is a cruel type of irony, and our technicians strive to find a solution to any of your HVAC problems. Read ahead to learn why your unit is blowing cool air and how heater repairs can correct the issue.
Reasons Your Heating System Is Blowing Cold Air
Dirty HVAC Filter
Your HVAC filter prevents airborne pollutants from circulating throughout your household air. It needs to be changed every three months, or it can become clogged with debris. If a clog occurs, it may block warm airflow to your system’s heat exchange. Thus, your unit will fail to heat your home as a result.
Pilot Light Is Out
If you have an older furnace, you may want to inspect your pilot light. The pilot light is a small blue flame that ignites your unit, allowing it to produce heat. If the light is not burning, your unit may continue to run and blow cold air throughout your home. A professional can safely reignite the flame for your convenience.
Thermostat Is On Wrong Setting
Checking your thermostat may seem self-explanatory, but incorrect settings are a common reason for your heater blowing cold air. Many homeowners can forget to reset their thermostats as the seasons change.
You can prepare your heater for cold weather by setting your thermostat to “heat.” The device can also utilize the “auto” setting so the fan can blow warm air throughout your home.
Clogged Condensate Line
Your HVAC system releases humidity as it operates, which eventually turns into condensation. The purpose of the condensate line is to carry moisture away from your furnace. Over time, debris can get stuck in your condensate line and cause it to clog. These obstructions can restrict airflow to your heating system and potentially create costly water damage to your unit.
Signs You Need Professional Heating Repairs
It’s normal for any home system to need maintenance at some point. Your unit may show signs of needing repair other than its inability to produce heat. A few indicators to look out for are:
- High energy bills
- Abnormal sounds and smells
- Uneven heating
- Difficulty starting unit
- Discolored or no pilot light
Few furnace repairs can be corrected without professional help. Your system can present a variety of hazards if you aren’t careful. If you’re in need of heating repairs, you should leave the problem to an experienced technician.
When You Should Get A Heater Replacement
Unfortunately, your heating system can’t last forever! The average furnace has a lifespan of about 15 years. As it ages, the need for repairs may become more frequent, and its overall performance may decline. If your unit is older and failing to produce warm air, you may want to consider a replacement.
