A poorly maintained furnace can have efficiency problems. According to the Department of Energy, furnaces operating at between 56%-90% efficiency can still eliminate 1.5 tons of carbon dioxide every year. However, it's important to take action to maintain your furnace to ensure it never falls below this range and ensure longevity of the furnace. If you want to keep your furnace running as long as possible, here are four tips to keep in mind.

1. Change Your Air Filter

Your furnace needs ample airflow to do its job, but a dirty air filter can restrict airflow. Changing your air filter regularly can help you keep your furnace clean and working properly. Plus, it promotes better indoor air quality. You should have your air filter changed at least every six months to avoid furnace repair.

2. Clean Your Ducts

The dust that clogs your air filter builds up in your ducts too. It's generally recommended to have your ducts cleaned at least once every three to five years to maximize the life of your furnace. Call a professional today to help protect your furnace from any damage.

3. Don't Crank the Heat

You might like your house warm and toasty, but you don't need to crank the heat up too high. Most people are comfortable with 68 degrees, but you shouldn't go higher than 70 degrees on a regular basis. Turning your heat up too high costs you money and overworks your furnace, which can lead to expensive repairs.

4. Buy a Good Thermostat

Investing in a good thermostat is another good way to avoid overworking your furnace. Buy a programmable or smart thermostat that gives you more control over your furnace throughout the day. Some can even be operated through a smartphone. This helps you avoid putting stress on your furnace to heat your house when nobody's there to enjoy it.

Avoiding costly furnace repair bills is as simple as staying on top of routine maintenance and following expert advice when it comes to using your furnace. These tips can also help you extend the life of your AC. If you want to get the most out of your furnace, call a technician at Paradise Heating & Air Conditioning to schedule service today.
