DIY Tips for Heating Repair and Furnace Replacement


Heating systems are essential to the comfort and safety of your home, especially during the colder months in Petersburg, MI, Britton, MI, Ida, MI, Dundee, MI, Lambertville, MI, and Ottawa Lake, MI. Understanding basic DIY maintenance and repair can save you time and money. However, complex projects should be left to professionals like those at Thompson Plumbing, Heating & AC.

DIY Tips for Heating Repair

Before you begin your DIY heating repair, remember safety comes first. Always ensure you have shut down power to the unit. For minor issues, such as the thermostat not working, double-check if the power is on and the settings are correct. If the heater is not blowing warm air, you might need to clean or replace the air filter. A dirty air filter restricts airflow and reduces the system’s efficiency. Always refer to your owner’s manual for proper filter replacement instructions.

Furnace Service and Maintenance

Frequent furnace servicing helps identify potential issues before they turn into major problems. To keep your furnace in top shape, regularly check the pilot light to ensure it is blue in color. Yellow or flickering light can signify a problem. Also, ensure the furnace area is clean and devoid of flammable items.

When to Consider Furnace Replacement

A furnace’s lifespan typically ranges between 15 to 20 years. If your furnace is within this range and constantly giving you trouble, it might be time for a replacement. Unusually high energy bills, frequent repairs, uneven heating, and loud noises from the unit are some signs that your furnace might need to be replaced.

DIY Heater Installation Tips

If you’re considering a heater installation, first, identify the type of heating system that best fits your home’s needs. Depending on the area you want to heat, portable heaters might not be sufficient, and a central heating system could be a better choice. When installing, ensure the heater is level for optimal operation. Be cautious while handling the unit, as rough handling can lead to damage.

When to Call Professionals

While some tasks can be accomplished with DIY methods, others require the expertise of professionals. Complex issues, such as furnace replacement and heating service, are better left to companies such as Thompson Plumbing, Heating, & AC. They have the tools and experience to ensure your heating systems are running safely and efficiently.


Being proactive with your heating system can save you from larger repair bills down the line. Stay ahead of potential problems by undertaking basic DIY repairs and regular maintenance. For more serious issues, don’t hesitate to contact professionals to ensure the job is done right and your home stays warm throughout the year.
