Importance Of Furnace Repair & Maintenance

The best way to avoid expensive furnace repairs is to have your furnace serviced regularly. Annual checkups by a licensed HVAC company can catch potential problems with your furnace early. Preventative maintenance will also ensure that your furnace is working efficiently, which will lower your monthly utility bills throughout the winter. Consider having your furnace serviced each year before you subject it to heavy use during the winter months.

During your furnace’s annual checkup, your AirPlus technician can:

  • Check the vent system, including the intake grills and filters, for leaks or blockages.
  • Inspect the heat exchanger for corrosion or cracks. A damaged heat exchanger is dangerous, as it can result in a carbon monoxide leak.
  • Check and clean the blower to reduce fire risk and prolong the life of the blower.
  • Check the burner and flame sensor.
  • Lubricate the motor and other moving parts to reduce stress on the unit and extend the lifespan, and check belts for signs of wear.
  • Inspect electrical components and tighten loose electrical connections.
  • Test thermostat calibration to ensure that your furnace is reading the temperature correctly.
  • Test safety controls.
  • Clean, check, and replace filters if necessary. A dirty air filter can cause a number of issues like insufficient airflow and wear on other components.

What’s wrong with my gas furnace? My gas furnace won’t turn on!
If your gas furnace won’t turn on, check:

  • The furnace switch, which should be located on or near the furnace and looks like a light switch, to see if it is turned off. If so, switch it on and wait a few minutes to see if the furnace starts.
  • The circuit breaker for your furnace to make sure it hasn’t been flipped. 
  • Your thermostat. Be sure it is set to heat (not cool) and that the temperature is set above the current temperature in your home. Some thermostats run on batteries, so be sure the problem isn’t simply that the batteries need to be changed. My gas furnace turns on, but the air isn’t blowing out correctly.

Check your filter to see if it is clogged or dirty and needs to be replaced.

My gas furnace is blowing out cold air.

  • Check that your furnace is being supplied with gas. If you have your own tank, check to make sure it isn’t empty. If you aren’t sure, you can check for a faint gas smell right after the air system turns on.
  • If your furnace has a pilot light, check that it is lit.
  • Check that your air filter isn’t clogged.
  • If your furnace uses an electric ignition source, check the igniter. When the furnace comes on, you should be able to recognize your igniter as a red glow underneath the furnace. If you hear a clicking noise when you turn on the furnace, but there is no red glow, this could indicate that you need to replace the igniter. 

If your furnace still isn’t working, or you need help identifying the problem, call AirPlus.

How much will it cost to fix my home furnace?

The average cost for furnace repair in the United States is around $250 to $400, but this varies widely depending on the specific repair work as well as the brand of your unit, and could be upwards of $1,000. For cheap furnace repair near Falls Church, VA that is reliable and fast, call AirPlus.

Some of the most common furnace repairs include:

Blower Motor Repair
The blower motor cycles the air from your furnace, through your ducts, and around your home. Blower motors need regular maintenance, and can fail because of too much dust in your heating system or from overheating. Blower motor repairs should always be performed by a licensed professional.

  • The average cost to replace a blower motor is around $450.
  • The average cost to repair a blower motor is around $150.

Igniter Repair
Igniters serve as an alternative to pilot lights on most newer furnaces, and are common culprits behind furnaces blowing out cold air.

  • The cost to replace an igniter is usually $300–$400.

Thermostat replacement
Your thermostat is what tells your furnace whether or not it needs to turn on, so while it may seem like a simple part of your furnace, it is important to be sure it is working properly.

  • The average cost for a replacement thermostat is $50–$200, depending on the type of thermostat you buy.

Flame Sensor

The flame sensor makes sure your furnace has fired and will shut down your furnace if it isn’t burning to prevent a gas leak. If your flame sensor goes bad, it may shut down your furnace unnecessarily, even when the furnace is igniting.

  • The cost to repair or replace your flame sensor can range from $80–$250.

Heat Exchanger

Your heat exchanger is one of the most important parts of your furnace, as it is the part where your air is actually heated. A cracked or damaged heat exchanger can be dangerous. In the event of a problem with your heat exchanger, turn your furnace off immediately and call a licensed repairman.

  • Average cost for simple repair of a heat exchanger is around $100.
  • Heat exchanger replacement cost can vary from $500–$1,200

Oil Furnace Repair & Maintenance Near Me

How do I know if my oil furnace is broken?

Strange noises coming from your furnace can alert you to a problem, such as knocking, rattling, or high-pitched noises. Your furnace may also need repairs or maintenance if heat isn’t flowing properly or heating stops altogether. Some repairs need to be addressed by an HVAC professional, but there are steps you can take at home to resolve some common problems yourself. For fuel oil furnace repair near Falls Church, Virginia, call AirPlus at (571) 470-7235.

  • Make sure your thermostat is working. Some thermostats run on batteries, so be sure the problem isn’t simply that the batteries need to be changed. Make sure the fan mode is set to automatic, so the furnace will turn on when it needs to, and that it is set to “heat”. You can also open the thermostat and make sure it isn’t clogged with dust.
  • Check the oil supply. Check the gauge to make sure you have oil in the fuel tank. You can also check directly using a dipstick if you suspect your gauge isn’t working properly. Don’t let your oil level get too low, or this can cause problems for your furnace.
  • Check the filter. If your filter is clogged or dirty, try changing it and see if the problem persists. Remember to change your filter regularly. It is also possible that the ducts themselves could be clogged, reducing the airflow throughout your home. If you suspect this is the problem, call a professional to check and clean your ducts.
  • Check your breaker box. Be sure the circuit breaker for the furnace is on and hasn’t been tripped. If you turn it on and it flips again, the problem may be with the wiring or circuit capacity for your furnace. 

My oil furnace is making a strange noise.

  • A knocking noise coming from your oil furnace can indicate that you have air in the lines. You will need to “bleed the lines” to get the air out. This can be done yourself, but can be frustrating for nonprofessionals, and the method will differ depending on your specific unit. Be sure to refer to the furnace manual if you attempt DIY repair, or call a professional.
  • A clattering noise can be the result of a loose access panel on the furnace. If you find a loose panel, simply tighten it to solve the problem.
  • A high-pitched squealing noise might mean that the belt or blower motor needs maintenance. Be sure to shut your furnace down before you check either component. Check for obvious problems, like if the belt has slipped or is loose. Sometimes the belt just needs a few drops of electric motor oil in its oiling ports, but if it looks worn, the belt may need to be replaced. 

A grinding noise may be the result of a problem with your furnace’s motor bearings. If you hear a grinding noise, you should turn your furnace off immediately and contact a professional, as this is not a problem that should be addressed yourself and can be dangerous if not fixed right away.
