Does your furnace keep blowing its fuse? If so, it’s time for some maintenance and possibly some furnace repair. The main reasons you are having likely this problem are as follows:

1. Grime

If your furnace hasn’t been regularly cleaned and maintained, it will have been steadily accumulating dust, debris, and dead insects. Over time, dirt building up in the air filter can transfer itself to the blower motor, resulting in the motor overheating and blowing the fuse. The fuse itself can become so coated with grime that the connection will break. All of this is preventable with regular service of your furnace.

2. Loose Wiring

Vibrations from a working furnace can loosen an internal wire and result in a short. Finding, tightening, or replacing loose wires is not a do-it-yourself job. Prevention is the best policy – have your system inspected and tuned up on a regular basis.

3. Old or Faulty Parts

These may include the following:
Blower Motor – When a blower motor is failing, it tends to draw too much power which may result in a short.
Starting Capacitor – A failing capacitor can result in intermittent electrical problems.
Transformer – The transformer, which runs the ignition, timers, and controls, is necessary to convert the system to run on the correct voltage. If it is worn and not working properly, it can cause a short.
Valves – When a valve in a gas furnace is unable to open and close efficiently, it can overheat, causing an electrical short and a blown fuse.

Don’t give yourself a headache by trying to fix furnace problems yourself. You can save yourself from blowing your own fuse by arranging for regular maintenance of your furnace. Give us a call to get on a regular schedule!

When it comes to heating your home, one of the most important things is that you have a well-functioning heater or furnace. To help make sure this is the case, it is suggested that you service your heater regularly. Here is some information to help you determine when the best time to service your heater is.


The best practice to undergo, when it comes to servicing your heater, is to do so on an annual basis. A technician should come to your home and review your entire system. In the end, this will help determine if any issues are present that need to be addressed.

When the Season Changes

In some instances, it is even a good idea to take a look at your furnace or heater when the season changes. This could be a good time to make sure it is ready for being used for the winter or being turned off during the summer.

When There are Issues

If you notice your furnace is not working properly, it is definitely time to think about servicing it. Doing so can help make the entire system last longer and work more efficiently. While you are working through these issues, you should also make sure you are cleaning your furnace and keeping debris from getting inside its working parts.

Avoiding servicing your heater could lead to serious issues like carbon monoxide poisoning or even house fires. For best results, make sure yours is being serviced at least on an annual basis. This will help keep you warm and safe in your home.

This time of year, our heating systems work overtime keeping our families safe and warm. But sometimes, it’s that same system that contributes to illness. If your family members have some respiratory issues that they just can’t shake, getting your ductwork cleaned may help tremendously.

Your heating system takes the air in your home, and circulates it through your HVAC system. That means any dust, dander, and other air pollutants keep getting pushed around. Some of that settles in the ductwork, and every time the furnace kicks on, it contributes to poor air quality.

People with asthma and allergies are particularly susceptible to problems when the furnace ducts are dirty. Any time air quality isn’t optimal, asthma sufferers are put at risk and may experience more symptoms than usual.

Winter allergies are also a big problem this time of year. Those with allergies to dust, dander, mites, and mold may have ongoing issues because all of these things accumulate in the ductwork, and people are spending more time indoors, where those allergens are present.

Then there are the average cold and flu viruses that are typical for the winter. While dirty ducts don’t cause these issues, the below average air quality can make a full recovery take longer than usual.

When you call for a professional duct cleaning, some companies simply show up and clean out the major air passageways. First, contact a company that will do a complete inspection to make sure your ducts need cleaning. Then, make sure they clean the entire system, including coils, coil drain pans, plenums, air filters, ducts, fans, vents and registers. When a thorough cleaning is done, you can rest assured that your air quality problems will improve.
