When Should You Repair or Replace Your Furnace?

Is your furnace prepared for the approaching cold wave? We bet you aren’t so sure! Before the bitter cold sets in, it’s essential to make sure that your system is working at its peak performance. However, if your unit is acting up and is giving you stress instead of comfort, it may need some repairs—or maybe it’s time to replace it entirely.  To help you make informed decisions, Environmental Heating & Cooling is here to shed some light on the question “When should you repair or replace your furnace?”

Dry or Dusty Home

An old furnace tends to fail more often, losing its ability to clean and moisturize the air in your space. Its built-in features like filtration and humidity control are starting to diminish. As a result, your indoor air may feel stale or stuffy, making your home very uncomfortable. You may cringe at the idea of replacing your heating system, but there’s nothing more at stake than your home’s comfort and family’s health.

Your Furnace is Emitting Carbon Monoxide

A cracked heat exchanger can lead to carbon monoxide leaks. This silent killer can pose health and safety risks to you and your family. Replacing your unit is the best course of action in this matter.

Cold Rooms that Never Warm-Up

Does your room never warm up even though your furnace is in full blast? There are many causes for this—an incorrectly sized unit, lack of insulation, or a poorly designed ductwork. Also, some systems aren’t as good at maintaining an overall even temperature in an entire heating space. Weigh all the costs involved, do the math, and get all the facts before deciding to get a new furnace.

Increase in Energy Bills

If your heating bill is climbing up without any change in energy usage, your system’s efficiency is going down. It means that your furnace is working twice as hard as it should. It’s best to call in a professional to diagnose the problem and provide you with viable solutions.

Frequent Costly Repairs

If your furnace is constantly malfunctioning and you often call a service technician for repairs, consider getting a replacement. Constant repairs add up, so do yourself a favor. Stop throwing your money away and invest in a new highly-efficient heating system.

Bottom Line

Sometimes, investing in a new and high-quality system can save you more in the long run. However, an inefficient furnace doesn’t always need replacement. If you experience any of the issues mentioned above, the first step you should do is turn to the experts at Environmental Heating & Cooling.

Frequent Cycling

If your heating systems go on short cycles more often than usual, this could mean a bigger problem. It’s either your furnace is too big for your space, or your thermostat has malfunctioned. The heat cycling issue of your heating system raises your energy bills and wears down the unit’s components. So, make sure you have the right size furnace and your thermostat is working properly.

Insufficient Heat

Furnaces are designed to provide warmth and comfort during the cold season. But if you’re getting chilly and freezing toes, this means that a few issues are at play. The main power is turned off due to burnt fuse or a tripped circuit breaker. Other reasons could be a defective igniter, insufficient fuel, or clogged filters. Any of these issues can be the culprit of a system that is not working. It is best to have an expert technician to diagnose the problem and fix it quickly.

Gas Leaks

Should you be worried if you notice unpleasant odors coming from your furnace? Definitely! Especially when it smells like rotten eggs or burning plastic, this a red flag that there’s a bigger problem in your heating equipment that requires immediate attention. Avoid lighting matches that can cause fire or explosion. Evacuate your home immediately, and call 911! To prevent this scary situation, here are some ways you can minimize the risk from gas leaks:
  • Install carbon monoxide detectors
  • Check your heater regularly
  • Have an annual heating system tune-up
  • Avoid DIY furnace repair

Airflow Problems

Airflow problems may arise if your heating system is not maintained regularly. Your indoor air can be compromised when your furnace’s filters, fan motors, and air ducts are neglected. This can also cause your unit to overheat and reduce its efficiency level. To avoid this issue, regular maintenance of your heater is the key. That means replacing your air filters frequently and hiring qualified professionals to inspect, clean, and fix your system.

Thermostat Issues

The thermostat controls your system’s operation. When it fails to work correctly, your heating equipment won’t function properly. So, make sure to set your thermostat to “heat” and replace the batteries if necessary. You may also consider upgrading to a programmable model that is more accurate and convenient.
