Furnace Problems We Fix

We offer the heating and AC repair services that homeowners need.

1. Furnace Blowing Cold Air: The primary causes of a furnace not heating up are dirty filters, a pilot light that has blown out, or a malfunctioning thermostat. Additional factors may involve ignition problems, issues with the gas valve, the blower motor, or other internal components.

2. Heat Keeps Turning On and Off (Cycling): Frequent cycling, characterized by repetitive on-off heating, can result from a damaged fan limiter, a grimy flame sensor, or a faulty thermocouple. If you observe this pattern, it is advisable to contact a local heating and cooling expert.

3. Blower Fan Does Not Turn Off: Typically, the fan limit switch might be set to “manual override,” but the cause could also be a short-circuited wire in the thermostat or at the fan limit switch.

4. Noisy During Operation: A buzzing noise emanating from the furnace might point to an electrical issue. If a loud noise occurs during startup, there could be a condition called “delayed ignition,” a serious problem where an excessive amount of natural gas accumulates in the combustion chamber before igniting.

5. Carbon Monoxide Detector Going Off or a Sulfur Smell Around Furnace: Carbon monoxide, a byproduct of natural gas combustion in furnaces, is typically contained within the heat exchanger and then vented through the flue to the outdoors. Smelling a sulfur odor, excessive condensation on windows, soot stains, or smoke stains around the furnace might indicate a potential gas leak of carbon monoxide.

6. Performance Does Not Improve Even After Changing the Air Filter: Dirty filters can obstruct airflow, causing the furnace to work harder to distribute heat. Changing furnace filters every three months is recommended, but clogged filters can sometimes lead to damage of the limit switch, which controls the fan.

7. Malfunctioning Thermostat: A furnace not turning on or failing to regulate temperature could simply be an issue with the thermostat or a flame sensor.

8. Issues with Ignitor or Pilot Light: This could result from a defective thermocouple or a gas furnace valve that is obstructed.

9. Burning Smell: During periods when the furnace remains unused, dust and dirt tend to build up on internal components. Upon initial use of the furnace, the scent of burning dust might be noticed. However, if this odor persists, it could indicate a larger problem with the furnace.

10. Utility Bills Keep Going Up: Incorrect temperature regulation by the thermostat or blockages caused by clogged vents or dirty air filters can lead to increased natural gas consumption and, subsequently, higher energy bills.

Why You Need a Furnace Tune-Up From Our HVAC Technicians

While there is no bad time to have a service provider visit for a furnace check-up, you may want to get it done sooner than later. A furnace tune-up will ensure that your furnace is ready for winter well before temperatures begin to drop.

You probably aren’t thinking about your furnace during the summer when your heating and cooling system is pumping out cold air, but this is the absolute best time to have a furnace checkup. This will allow you to identify any broken or worn parts before they cause further problems, improve your efficiency and indoor air quality, and enjoy a more comfortable home throughout the colder months.

Stop Furnace Problems Before They Ever Occur With Scheduled Annual Maintenance

Investing in annual furnace maintenance should be a priority because it can help you save money during the lifespan of your furnace.

It is natural for a certain amount of wear and tear to happen in the winter months when the furnace is running consistently. This can make the furnace lose efficiency and increase your energy bills.

In addition, annual maintenance will reduce the chances that you will need repairs and prolong the life of your furnace. Replacing your system with a new furnace can be a costly and unwelcome expense. The best way to avoid any emergency services and keep your home safe and comfortable is with regular maintenance.

How to Tell if Your Furnace Needs Cleaning

If your furnace is dirty, that means that dirt and grime are being spread throughout your home.

While you should have your furnace cleaned every year, you can also be on the lookout for signs that it is time to call the heating & air conditioning professional to come out for cleaning.

  • Is your air filter dirty, even after changing? If the answer is yes and it is already full of dirt and dust after a few days, your furnace needs to be cleaned.
  • Are your energy bills rising? If the answer is yes, a dirty furnace could be to blame because it is working harder to heat the home; therefore, it needs to be cleaned for better energy efficiency.
  • Is the color of the burner flame yellow or orange? If the answer is yes, then you need to take action immediately because a clean flame will actually be blue.

Without a thorough cleaning, your furnace could start releasing carbon monoxide into the home. This odorless gas can be deadly, so it is imperative that you call a furnace professional as soon as you notice that the flame isn’t burning blue.
