Has your furnace been acting up, and you are just not sure what’s going on? From unpleasant smells to a stubborn furnace that won’t start, several reasons could cause your HVAC system not to run as it should. Middletown Heating & Cooling would love to assist you with pinpointing what might be causing issues within your furnace. Here are some common questions that come up when dealing with a faulty furnace:

1. What Is That Sound? 

Humming. Buzzing. Screeching. Rattling. None of these are sounds you want to hear coming from your furnace. If your furnace is making unsettling noises that you normally don’t hear, this could be due to several factors such as improper blower assembly, loose screws or particles, a bad belt or motor bearing, or even leaky ductwork.

2. What Is That Smell? 

If you smell a strong odor coming from your furnace, that is a solid sign that it is time for your annual furnace tune-up and safety check. However, it is common to have smells coming from your gas or electric furnace the first time it is turned on for the winter. Our experts suggest inspecting the heat exchanger and the rest of the unit for any dust that may be collected on its surface. Also, check the filter. If an air filter is covered in dust, it can produce an unpleasant smell.

3. Why Is It Leaking?

While there are numerous reasons, your furnace could be leaking water, the most common reason for a water leak is due to condensation. If you have a high-efficiency furnace in your home, it produces condensation. Leaks will happen when the tubing for the condensation becomes clogged, or if there is a break in the line. Leaks can also occur if the floor drain is clogged and the water has nowhere to flow.

4. Why Won’t It Stop Running?

Have you noticed that the furnace just seems to be running nonstop? Don’t worry, this is a common issue. Check to see if the thermostat’s fan setting is set to “on.” If it is, change it to “auto.” Then turn the thermostat to a temperature level that is lower than the room temperature you have it set at. If it still doesn’t kick on, contact one of our specialists at Middletown Heating & Cooling and get an appointment scheduled today! 

5. Why Does It Keep Shutting Off? 

Unfortunately, the fact of the matter is that furnaces can short cycle. However, another possibility is that your furnace could be sized incorrectly for your home, causing it to be overworked. And last but not least, dirty filters can clog your airflow and cause your HVAC system to short cycle. Remember to check those filters any time if you have any problems with your furnace.

If you have gone through this list and are still encountering problems with your furnace we would highly recommend scheduling an appointment with a technician. While some issues might seem small, they are normally symptoms that are surfacing from underlying issues.
