Winter can be beautiful, but when your heating system starts acting up, everything becomes uncomfortable. During piercingly cold months, residents of Durango, Colorado, rely heavily on their heating systems. That is why timely repairs and heating maintenance in Durango are essential to keep your heating unit running at its best.
In this blog, let’s discover the telltale signs that your heating equipment might need attention. Understanding these warning signs early allows you to resolve minor issues before they escalate and keep your home warm and cozy all winter long.
Signs Your Heating Unit Requires Heating Repair Services
It’s not rocket science to determine whether your heating equipment needs repair. However, for an average person, spotting the issue might be challenging. Most signs that signal your heating unit needs heating repair services are unostentatious, and overlooking them is easy.
Here are 6 signs that your heating unit needs attention:
Excessively High Utility Bills
If your monthly utility bills are outrageously high, odds are your heating unit is the culprit. Moreover, if your gas bill is also off the chart, again, it's your heater that might be malfunctioning.
Over time, your heating system’s efficiency decreases, and it may take more time and consume more energy to reach the desired temperature.
It’s worth noting that sometimes electricity companies also increase their rates. However, if the bill suddenly skyrockets without a clear reason, it could be a sign your heating unit needs heating repair services.
Yellow Burner Flame
We are all familiar with the steady blue flame of a furnace burner. However, if the burner flame is yellow instead of blue, it may be a sign that there is something off about your heating system.
A yellow flame signals the presence of carbon monoxide in your house. It is a colorless and odorless gas that can be highly detrimental to your health. Excessive exposure to carbon monoxide can cause extreme health risks. Therefore, it’s utterly vital to address the issue before it escalates.
If you notice your furnace burner’s gas turns yellow, opt for professional furnace services in Durango immediately.
Moreover, you must also look out for flu-like symptoms, which may also be caused when your body comes in contact with carbon monoxide. Dizziness, nausea, and fatigue are some of them. Leave the house as soon as possible and contact a reliable heating repair company to inspect your equipment.
Strange Sound from the Furnace
Occasional rattling, cackling, or banging sound is common in old heating units, be it a heat pump, HVAC, furnace, or broiler. If you are also experiencing the same with your equipment, it’s best to seek assistance from a professional.
Common noises like squealing could mean issues with your heating unit’s motor bearings. Rattling usually indicates your blower assembly needs repairing. A loud creaking noise when you turn on your heating system is never a good show for the guests.
So if your heating system is making weird sounds, you need to check it out. Unless you have rats, you will need expert assistance.
Thermostat Requires Frequent Adjustments
If your heating system is waking you repeatedly to adjust the thermostat, it could be a clear sign that something isn’t working properly. You may have observed that some places in your home are perfectly comfortable while others remain either too hot or too cold.
If the temperature is continuously fluctuating even after several adjustments, the problem may not be with the thermostat itself. The issue could lie within the heating unit. Most of the time, it’s the furnace that is not evenly distributing the heat throughout the room, resulting in some places being overly chilly while others being excessively warm.
Before things get out of hand, it is advisable to address this issue before it worsens. In some cases, the problem can be fixed with professional repairs. However, resolving issues with older systems may benefit from a complete heating installation in Durango to restore consistent comfort throughout your home.
Age of the Heating Unit
Like any mechanical system, a heating unit will eventually wear out over time. Most heaters typically last between 15 and 25 years, depending on how well they are maintained and how often they are used.
One easy way to tell if your system is quite old is by checking the pilot light. Many older heating systems rely on a pilot light, which can indicate that your heater may be close to 20–25 years old.
As heating systems age, they become more prone to breakdowns and tend to operate less efficiently. This reduced efficiency can also be one of the reasons your energy bills keep climbing. If your unit is nearing the end of its lifespan, it may be time to consider repairs or even a replacement.
Overheating & Short Cycles
Short cycling occurs when your heater repeatedly turns on and off within a short period of time. Normally, the thermostat regulates your home’s temperature and signals the system when to start or stop.
However, when the heater keeps going on and off unexpectedly, the issue may not be with the thermostat. Instead, it could point to a deeper problem within the heating system.
In many cases, short cycling happens when the heat exchanger overheats. When this occurs, the system automatically shuts down as a safety measure. Once the exchanger cools down, the heater turns on again—only to repeat the cycle.
If your heater starts short-cycling, it’s important to choose professional heating repair services as soon as possible. Ignoring the issue could leave you dealing with a much colder winter than expected.
Final Words
Most homeowners wait until winter arrives before getting their heating system inspected. However, regular inspections are essential for keeping your heater running efficiently and avoiding unexpected breakdowns.
Knowing how to spot early warning signs can help you address minor issues before they turn into costly repairs. But if you find yourself calling for repairs every few weeks, it may be time to consider a complete upgrade of your heating system. It’s also important to schedule regular maintenance to keep your system running efficiently throughout the year.
