Questions About Your Furnace or Boiler? Our Heating FAQs Have the Answers

Furnaces and boilers are complex systems, so when they struggle or break down, there’s not always a clear reason. That’s why the pros at Roth Heating Company answered some of your most frequently asked HVAC questions. Find the tips you’re looking for in our heating FAQs below, then call if you have any additional questions.


1. How Long Will My Furnace Last?

The easy answer is that it varies. If you have routine maintenance done on your system, you can generally expect them to last between 15 and 20 years. Factors such as what type of furnace you have, how harsh the winters have been, and how often your unit has needed repairs also plays a role. Rest assured that should you need a new furnace installation, Roth Heating can handle the whole process from start to finish.


2. How Can I Tell If I Need a New Furnace?

If your furnace is 10 years or older, it will likely give off some warning signs that it needs replacing. These include but are not limited to reduced or little warm airflow, frequent repairs, high energy bills, loud noises, and strange odors. However, routine maintenance can help catch problems before they break down your system—we recommend scheduling service once a year.


3. If I Have an Old Steam Boiler, Is It Worth Replacing?

Not only does it make sense, but we recommend it. Newer hot-water boilers are much more efficient than older models, meaning these systems end up paying for themselves in terms of lower energy bills. These boilers are also easier on your pipes. They also work in tandem with radiant heating system—this heating method circulates hot water through pipes in your floor for comfortable and even warmth throughout your home.


4. Why Is My Thermostat Screen Blank?

It may be as simple as dead batteries in your thermostat. If replacing the batteries doesn’t bring the system back online, your circuit breaker might be tripped, or there may be a bigger problem in your furnace. Call Roth Heating right away for fast, efficient service.


5. My Heat Just Went Out During a Snowstorm—Can I Fix It?

Check the plastic heat vent pipe located outside your home—light, fluffy snow can float in and clog the pipe (though heavy packing snow typically does not cause this issue). If that’s not the problem, call Roth Heating immediately for emergency help.


6. How Often Should I Replace My Air Filter?

As your furnace moves air through your house, it also blows contaminants such as dust, dirt, pet dander, and even bacteria. Your air filter catches most of these contaminants before they cause problems, but it gets dirty in the process and can eventually block airflow and impact your indoor air quality. By replacing your filter once every one to three months, you can keep your air clean, healthy, and flowing properly.
