Signs Your Furnace Has a Problem
There are times when something goes wrong in the heating process. Though this sometimes leads to an obvious problem—a complete system breakdown—this isn’t always the case. Much of the time, the signs you need to call a Andover HVAC contractor are much more subtle. To prevent big problems from snowballing into larger ones, it’s important to be on the lookout for the following:
- Weird Smells: When you first turn your furnace on for the year, you might notice a musty smell. This is typically dust burning off that settled over the months your furnace sat idle. This will dissipate as the unit operates and isn’t anything to be concerned about. If you notice an odor that suddenly appears or refuses to go away, however, it’s time to call an HVAC professional.
- Odd Noises: Is your furnace banging or making some other kind of noise? This can be the result of numerous issues with the unit and is best diagnosed by a heating repair expert.
- More Service Calls: Most every furnace in the Lexington or Andover area will have a part fail and need service in its life. In fact, one out of four people in the US will have an HVAC technician in their home every year. But if you’re making multiple calls in a heating season, it’s a sign you’ve been propping up a system that is aging out. Note that service calls don’t include preventative furnace maintenance visits.
- Climbing Utility Bills: There are many reasons your electric or gas bills can rise. Cooler temperatures are an obvious reason. But, if your fuel usage suddenly increases dramatically, you probably should have it checked ASAP.
- Visual Rust: While some amount of rust is expected with age, excessive amounts—especially on the flue—can be a sign of improper venting. If a roof or plumbing leak is causing furnace corrosion, it’s not just an eyesore. It can be dangerous. If the system rusts through to the heat exchanger, your home could be contaminated with deadly carbon monoxide. So, if you notice an issue with rust, give Royal Air Systems, Inc. a call.
- Frequent Cycling: If your system is constantly flicking on and off, there’s something stopping the unit from working properly. Unfortunately, this can be difficult to diagnose due to a variety of potential causes. To get the problem located and fixed quickly, rely on our heating repair experts.
- Start-Up Problems: Does your furnace not turn on when it drops below the indicated temperature on your thermostat? Are you hearing clicking noises on start-up? These issues often signal an upcoming furnace breakdown. So, if you ever notice them, give us a call at (978) 664-5023.

The Top 5 Causes of Furnace Failure
It’s important that homeowners understand what parts of their furnace are most likely to fail. This can better prepare them to communicate with us about their heating problems. When fixing heating systems in Andover, we often find the following culprits, some of which can save you a service call:
- Clogged Filters: When was the last time you swapped out your furnace filter? If the answer is more than a few weeks ago, it might be time to check it, especially if you have more than one pet that sheds heavily. When running, your heating system pulls in dust, dander, and dirt. This is kept out of the mechanical parts by your furnace filter. A clogged filter restricts airflow, making your heating system work harder and eventually begin to cycle on and off. Replacing it not only helps efficiency, but also improves air quality.
- Bad Thermostats: Your thermostat is responsible for signaling your furnace when to turn off and on to maintain the set temperature. If it’s not working properly, you’ll struggle to get warm. For instances where the thermostat may be at fault, make sure its batteries are good, if it uses any. Also, double-check that it is set to HEAT with the run method on AUTO.
- Ignition Failure: Sometimes the pilot light or surface ignitor will fail and refuse to light the burners. If this happens your furnace won’t be able to heat the air, leaving you in the cold. To prevent this, have it checked and cleaned annually by an Andover-area HVAC professional.
- Exhaust Blower Issues: The furnace exhaust blower is what takes the combustion gasses out of the heat exchanger and vents it safely outdoors. If this component fails, the furnace will cycle on and off or shut down. Regular inspections and maintenance visits can prevent this from happening.
- Blower Motor Failure: The blower motor is essentially what keeps the air moving around your home. Should this component fail, it doesn’t matter how efficient your furnace is, the hot air won’t be distributed around your home. The blower can fail from overheating or from it becoming clogged with debris. Have your ducts cleaned and your furnace tuned up to keep the blower working effectively.
- Bad Heat Exchanger: The heat exchanger is one of the most important components of a conventional furnace. It is the component that safely transfers heat from the flame into heated air that is circulated in the home. When the heat exchanger develops holes or cracks, replacing it can be quite expensive. Some people prefer to simply replace their old furnace. An expert evaluating your system can best advise you as to what might be in your best interest.
