Is It Time To Replace Your Furnace?

Baby, it’s cold outside, and if your furnace isn’t functioning properly, it’s about to get a whole lot colder. You’ll want to make sure your furnace is not only working, but working efficiently before those bitter temperatures take hold. Here are some things you should know.

Age Matters

When evaluating if you should replace your furnace, you’ll want to first take a look at the age of the unit. A quick flip through the owner’s manual will show you the year your furnace was made. If you can’t find the manual, call the manufacturer and give them the model number of your system. Most furnaces need to be replaced around 15-20 years old.

Equipment Longevity

Furnaces can last 20-25 years. Even so, if your unit is more than 15 years old it’s a good idea to have it checked by an HVAC technician. Sometimes an aging unit will have to have multiple big ticket repairs. In this case, purchasing a new furnace is more cost effective and may save on energy bills in the long run.

Energy Savings

Energy Star certified gas furnaces can save both energy and money. Gas furnaces in the Northern states are up to 16% more energy efficient than the baseline models. This equates to an average savings of $94 per year. By upgrading to a high-efficiency system, you can cut your energy costs while keeping your family perfectly comfortable You can see just how much you can save on your energy bill by checking out this energy savings calculator.

Quick Tip!

When replacing your furnace, brands do matter, but proper installation matters more when it comes to energy savings and comfortability. A Suter HVAC installer will make sure the duct work is clean, unclogged, and dust-free. They will also measure sheet metal fittings to properly connect to your new furnace. If crucial steps are not taken, air could be leaking around your furnace or the air flow could be restricted.

Warning Signs. Besides age, there are some other red flags that could lead to a furnace replacement:

Thermostat Issues

Does it feel like you’re constantly adjusting your thermostat in order to stay comfortable? Are some rooms warmer or colder than others? This could be a sign that your furnace isn’t distributing air properly.

Noisy Furnace

Have you heard any banging, popping, squealing, or rattling coming from your unit? Weird noises are a cause of concern. A lot of times, this is an indicator that your furnace is on its last leg. Also, be on the lookout for your blower turning on and off frequently or blowing cold air.

Gas and Electric Bills on the Rise

As a furnace ages, it loses its efficiency. This is especially the case if a furnace hasn’t properly been maintained. With a lack of regular maintenance, a furnace has to work harder to put out the same amount of heat as before. This will cause an increase in your gas and electric bills. Making sure you change your filter regularly and having annual furnace tune-ups is key.

Dusty or dry home

Old furnaces often cannot properly moisturize and clean the air in your home. Has anyone in your home been experiencing dryness of the skin, throat, or nose? Does your home feel stuffy or stale? If so, your furnace may not be functioning as it should. We offer whole-home humidifiers to keep the air in your home comfortable and cozy.
