What to Watch Out for in a Failing Heating System

As the colder months roll in, winter’s icicles and severely cold temperatures are on their way. This means it’s high time that you make sure your heating system is in good operating order. Read on to discover what to watch out for in a failing heating system (and why you should replace yours!).

The Headache, Dizziness, and Nausea

If you or a guest has symptoms such as nausea, headaches, or burning in the eyes or nose, have your home examined for carbon monoxide. Carbon monoxide detectors are available from a wide range of hardware stores. Carbon monoxide can fill a home in this manner when the heat exchangers in older furnaces develop holes or cracks, allowing carbon monoxide to enter.

If you experience any of these symptoms, seek medical attention right once.

The Accumulating Dust

If the interior air quality is poor, your family’s health may be jeopardized, and an abundance of dust may aggravate asthma and allergies.

Because our summers are so long and hot, we leave our heating systems off for several weeks at a time. It is possible that dust will be distributed throughout our homes if they are reused. Increased dust levels do not indicate that your heating system needs to be fixed or replaced, but it does indicate that it should be cleaned.

If you see an excessive amount of dust, it is time to clean up your HVAC system. Dirt and dirt can cause the system’s components to corrode, necessitating costly repairs.

The Increasing Energy Costs

It’s probable that your home’s older heater is to blame for your continuously rising electricity bills. The increasing rate of power consumption, as well as the number of on/off cycles, may cause a system to fail.

If you’ve noticed a continuous increase in your electricity bill over the last four years, it’s conceivable that you need a new heating system.

The Variations in Temperature

If you have a traditional heating system with no zones, the temperature in each room should be the same. If one room in your house is noticeably cooler than the others, you either have an ineffective heating system or dwell in a haunted house. This could indicate that your heating system isn’t working properly.

Temperature swings at the doors and windows should be reduced to a minimum by a well-functioning system. Because heat goes uphill, you may sense a temperature change as you progress up the steps. If the temperature in your home fluctuates and there are drafts, you may need the help of a professional.

The Confusing Thermostat

You might be left confused and annoyed when several of your rooms are unbearably hot. This could be due to a broken thermostat and a heater that isn’t functioning properly.

The temperature of a heating system should only be changed overnight and first thing in the morning. If you have to get up in the middle of the night to adjust the thermostat, you should have it examined.

If you’re tired of manually regulating your thermostat at night and in the morning, you should consider investing in a programmable thermostat. If all of its components function properly, modern technology is truly amazing. If you frequently fiddle with your programmable thermostat, you should have it serviced.

The Strange and Disturbing Sounds

A properly functioning heating system should work quietly. If it produces an abnormally loud noise, have it checked out. Do not ignore such disturbing sounds!

There are several probable explanations for the unusual sounds:

  • Screeching could be caused by loose bearings, pulley problems, or a worn belt on the inducer or blower motor.
  • If the blower fan motor dies, you may hear a buzzing sound.
  • Unbalanced motors, loose screws, and shaky ducting can all contribute to the rattling sound.


This winter, you’ll need a dependable heating system that won’t let you down. As such, you should replace (or repair) a faulty heating system. Remember that a well-maintained heating system can prevent pipe bursts, keep the air inside your home clean, and heat your home more efficiently. With a fully functioning heating system, you can keep yourself and your family safe, healthy, and comfortable for the winter season.
