Why You Need Maintenance on Your Furnace Now

The comfort of your home depends on the temperature of each room throughout the year. You want to be sure your furnace is always in working condition so you can monitor and control the climate in your living space.


Keep reading to find out how often your furnace needs maintenance, or schedule your appointment today with Jack Lehr Heating, Cooling & Electric in Allentown, PA.

How Often Does a Furnace Need Maintenance?

To keep your furnace running properly for as long as possible, it is important to have it cleaned and maintained at least once a year—preferably in the fall before the cold really settles in on the Greater Lehigh Valley area. A heating system can wear itself out quickly, especially if you don’t take the proper measures to ensure it stays in working condition. An annual checkup prevents your furnace from needing costly repairs and keeps you and your family safe from possible carbon monoxide emissions. To save even more money, sign up for a furnace maintenance agreement with Jack Lehr. You’ll extend the life of your HVAC equipment and receive several extra perks.

What Are the Steps of Proper Furnace Maintenance?

Depending on what kind of furnace is in your home, there are different steps in the maintenance process. But no matter the type, these three basic tasks are performed during regular checks to ensure your safety and prolong the life of your furnace:

  • Fuel is mixed with air and ignited, heating a sealed chamber
  • Fresh, filtered air blows across the outside of a hot chamber and into the heating ducts
  • The exhaust from the combustion chamber is vented out

How Do You Know When It’s Time to Replace Your Furnace?

Even if you schedule your furnace maintenance annually, there will come a day when you need to replace your system. Answer these questions (or talk to one of our professionals) to determine if it’s time to schedule replacement with a new, more energy efficient system.

  1. How old is your furnace?

Furnaces last on average between 16 and 20 years. It’s a good idea to replace your furnace before it breaks, so you’ll have time to shop around and make the best decision.

  1. Are your energy bills increasing?

Furnaces become less efficient with age, especially if they haven’t been properly maintained throughout the years. If your energy bills are rising in cost, it may be time to purchase a new furnace.

  1. Has your furnace needed repairs in the past year or two?

During the last few years of their lives, furnaces tend to need the most repairs. It can save you time and energy to start investing in a new furnace instead of paying for costly repairs time and time again.

  1. Is your furnace making unusual noises?

Old furnaces start making unusual noises when they get older. If you’ve heard any type of banging, popping or rattling coming from your furnace, you may want to start shopping for a new one.

  1. Is your furnace keeping your home at comfortable temperatures?

If some of the rooms in your home are cold while others are hot, your furnace could be lacking the ability to distribute the air evenly throughout your entire living space.

  1. Is your living space dry or dusty?

If your home is feeling dry and dusty, your furnace could be failing to clean to air in your living space. It may be time to start shopping for a replacement furnace.

  1. If you have a natural gas furnace, is the burner flame yellow or blue?

A yellow or flickering flame could be a sign of carbon monoxide emission. It’s important to keep carbon monoxide detectors in your home, close to the furnace room to be sure you and your family are safe.
