Furnace Repair Service

North Texas winters at times can be brutally cold. During these times the last thing you want to worry about is your furnace not working. If you find your furnace has shut down or stopped blowing cold air, fixing the problem may be a simple fix.

We have listed below some items to check prior to calling your heating repair contractor.

1. Check the Air Filter and Change If Needed

We mention this all the time but with everyone’s busy schedule it is the one thing we find that people neglect to change. If the furnace filter is to dirty, it will reduce or even block air flow to the furnace.

A dirty filter causes these problems:

• Reduces volume of hot air blown out– Blocked or reduced airflow equals less air the furnace has to supply your air vents.
• Furnace shuts off – With the lack of airflow your furnace has to run longer to heat your home, the heat exchanger overheats or safety switches overheat, causing the furnace to automatically shut down.

A dirty filter can also cause a buildup of soot, dirt, dust and pollens in the furnace, causing your furnace to run inefficiently and reducing the life span. Check the air filter regularly and especially if you are experiencing issues.

2. Check your thermostat

If your furnace isn’t coming on or not maintaining the temperature to keep you comfortable, check the thermostat.

• Make sure the thermostat to “heat” and not “cool.” (You never know if someone accidently changed the settings)
• Increase your thermostat about 5 degrees above room temperature to see if your furnace comes on. (Remember: Your furnace may have a time delay, so do not worry if it does not come on immediately.)
• Replace the batteries.
• Open the thermostat exposing the connections and gently blow out any dust or debris. (We recommend you make certain what thermostat you have and following any manufacturer suggestions before trying this.)

3. Make sure all Furnace Doors are on and Secured

If anyone has been working on or performing maintenance on your furnace, they may not have secured all the doors properly. If it’s not secured properly, a safety door switch will prevent the furnace from running. .

4. Check You Ductwork

If most of your home is heating properly but you have some rooms that are colder than others you may have an issue with some of the ductwork.

If your ductwork has manual dampers, make sure they are fully open to the rooms in question. Manual dampers are typically connected directly to the furnace plenum. You can check the internet to determine how to adjust your particular damper (if a damper is installed.)

If some of your rooms are still cold, your ductwork may have leaks, tears, or cracks allowing hot air to escape in your attic. Follow the ducting feel around for any airflow escaping to the attic. These leaks are not only reducing the airflow to the desired room, it can also increase your electric bill and pull dust and pollutants into your home creating poor air quality. If you find these leaks we recommend they be sealed with a mastic sealant.

5. Has the Gas Valve has not been turned off

Like with the furnace doors not being secured, someone may have shut the gas valve to do a repair or maintenance and forgot to turn it back on. If it’s off, no gas is getting to the furnace allowing it to work. Simply turn it back on (the handle should be parallel with the gas pipe.) and you’re good to go.

6. Check the Breakers and Electrical Switches

Someone may have shut the electrical power to do a repair or maintenance and forgot to turn it back on or someone came out of the attic and flipped the switch off. Since a gas furnace is only 110 volt, typically it is a controlled by a simple light switch. Simply turn it back on and the system should start working.

The steps above are a few options to try if your furnace stops working. These could save you some money without having to call your heating repair company.
