F.A.Q.

With over 65 years in business, Tom’s Heating Service has answered countless HVAC questions. Whether you have a quick question about your furnace or need to brush up on your boiler knowledge, our heating FAQs have the answers you want.

How Can I Tell If I Need a Furnace Replacement?

If your furnace is ten years old or older, it will likely show signs of declining efficiency. Regular maintenance can improve its operation, but if you experience a slow system, reduced airflow, higher-than-normal energy bills, strange odors, or loud noises, it might be time to consider a replacement.

Why Is My Furnace Blowing Cold Air?

Check your thermostat to make sure it’s set to “Heat” and not “Cool.” If it is, check the furnace itself to see if the air filter is dirty or if the drain hose is plugged—these are other common culprits. If these tips don’t work, call one of our professionals right away for a repair. You could have a more serious problem on your hands.

How Long Will My Furnace or Boiler Last?

The lifetime of your heating system depends on how well and how often you have it serviced—routine maintenance is key to maximizing system efficiency and performance. However, on average, a furnace will last anywhere from 12 to 15 years, while a boiler’s lifespan ranges from 15 to 30 years.

How Often Should I Replace My Air Filter?

You should change your air filter every one to three months—or more often if you have pets or bad allergies. If you use a high-efficiency media filter rather than a standard one-inch version, swap it out every six to 12 months. This will help it catch airborne pathogens and contaminants without blocking airflow.

What’s Better—a Furnace or a Boiler?

Generally speaking, both are fantastic heating options. If you’re choosing one for a brand-new home or business, our team will walk you through your options, including the pros and cons of a furnace vs. a boiler. If you’re considering a new system for your current home, we recommend you stick with the same one you already have—retrofitting your layout to include new pipes or ductwork can be a long and expensive process.

How to Save Money on Your Heating Bills?

There are a few simple things you can do to curb heating costs:

Keep curtains and blinds open during the day to let the sun’s natural warmth into your house.
Leave your thermostat alone—frequently adjusting the temperature up or down can make it harder for your system to keep up with demands.
Wrap windows and seal doors to prevent heat from escaping and you from wasting money.
