As the temperatures dip during autumn and winter, hundreds of individuals will contact furnace repair professionals due to a heating system malfunction. Whether it’s residential or commercial, there are some common issues that afflict furnaces alike. If you’re aware of what these typical furnace problems are beforehand, you can take proactive steps to prevent them from occurring in the first place!
Top 10 Furnace Problems
To help you with your furnace troubles, here are the 10 most frequently encountered issues and some tips on how to effectively repair them. That way, you’ll be prepared for any future furnace malfunctions!
1. Lack of maintenance
By allowing your furnace to go unchecked each year, you are putting yourself at risk of dealing with breakdowns and unexpected issues. That’s why it is so important to not only schedule routine maintenance appointments but also inspections that can help the appliance run more efficiently and consistently.
2. Dirty Filters
An accumulation of dirt and debris on air filters restricts airflow, causing your furnace to exert extra effort in order to circulate. In extreme cases, a congested filter can even endanger the limit switch which is responsible for regulating the fan speed.
3. Wear and tear
Overtime, ordinary everyday usage can lead to issues with ventilation, temperature regulation or even extreme heat.
4. Electric ignition or pilot control problems
Your home or business space may quickly become cold if your pilot light fails to ignite due to a faulty ignition, thermocouple issues, drafts in the appliance, or clogs. To keep warm and cozy temperatures maintained, it is essential that these potential problems are addressed right away.
5. Malfunctioning thermostat
A malfunctioning thermostat can not only bring about discomfort but also cause fan issues.
6. The furnace doesn’t heat at all
A malfunctioning furnace may be due to a variety of issues such as an incorrect thermostat setting, electrical failure, gas problems or even the pilot light being out.
7. The furnace doesn’t heat enough
Not only can a blocked filter prevent your furnace from functioning properly, but an incorrectly sized heater may also lead to insufficient warmth in the space.
8. Frequent cycling
It may be a sign of an obstructed filter, inadequate air circulation or incorrect thermostat settings when your device switches between “On” and “Off.”
9. The blower continuously runs
Experiencing difficulties with your blower? It could be due to a malfunctioning limit switch, which requires the attention of an expert technician for replacement.
10. The furnace is too noisy
Unusual noises such as rumbling, squeaking and rattling can be indicative of a mechanical issue, airflow limit or blocked burners. Don’t let these signs go unnoticed – they could lead to bigger problems in the future!
Steps You Can Take To Maintain Your Furnace
- Maintenance:To keep your furnace in excellent condition, it is vital to book routine maintenance with a professional at the conclusion of summer or start of fall each year. This will not only prepare you for winter weather but also nip any potential issues which could lead to costly repair bills during hectic winter months.
- Check the circuit breaker and power supply:If your furnace is not functioning or the thermostat’s display has gone dark, it may be due to a fault in the circuit breaker or a blown fuse. Also ensure that the power cord is securely connected into an electrical outlet.
- Reduce drafts:If a draft of air affects your pilot light, you may want to shut the windows or doors in that area.
- Change the air filters: Neglecting to clean or replace your air filter can lead to an array of furnace issues. To avoid any problems, make sure you are regularly cleaning or replacing the filter once per month as instructed by the manufacturer’s instructions.
- Check the thermostat: If it appears your furnace is failing to generate heat, then you should check the battery level in your thermostat. On some models, merely changing out the battery can be enough to remedy the situation.
Is your furnace not working? If so, it might be time to invest in a new one or call an experienced technician to come and fix what’s wrong with the current model.
