Cold Air Blowing
Cool air coming through the vents may indicate a problem with the gas valve, pilot light, or heat exchanger.
Poor Air Flow
Insufficient airflow could stem from issues like clogged filters or blocked ductwork.
Strange Noises
Banging, squealing, rattling or whirring sounds coming from the furnace can mean a component is loose or failing.
Excessive Dust or Rust
Abnormal amounts of dust being circulated or components showing visible rust and corrosion.
Frequent Cycling On and Off
Could point to a number of issues including the blower motor, air flow or faulty thermostat.
Weird Smells
Strange, pungent smells can signal serious problems such as gas leaks or electrical issues.
High Energy Bills
Rising bills with no major changes to usage are a red flag that your aging furnace is operating inefficiently.
Old Age
Once a furnace exceeds 15-20 years, it has likely reached the end of its useful lifespan and will continue to need more frequent, costly repairs.

frequently asked furnace repair questions
Get answers to your most pressing furnace repair questions.
Contact usHow do I know if I need a furnace repair or furnace replacement?
Several factors go into this decision, including the furnace’s age, repair costs compared to a new system cost, your energy expenses, and if it’s a recurring issue. As a general rule, if an aging furnace requires repairs over 50% of a new furnace install price, replacement is typically recommended. When considering these factors, it’s wise to find furnace installation companies near me to get expert opinions and quotes.
Why is my furnace not heating properly?
Common issues could include a dirty air filter, worn-out components like the blower motor or thermostat, or problems with the ductwork restricting airflow. It’s best to have a professional inspect any issue if you are not getting consistent heating.
How often should I change my furnace filter?
It’s recommended to change your furnace filter monthly, especially during high usage periods to maintain air quality and efficiency in your furnace unit.
