Troubleshooting Your Furnace Until a Columbia HVAC Company Can Get to You

columbia plumber, columbia air conditioner, columbia hvac, troubleshooting your furnace

It’s cold, your furnace just quit on you, and every Columbia HVAC company you’ve called is booked. Or maybe your furnace died at 3 am on a Tuesday or 3 pm on a Sunday, and you’d rather not pay the after-hours rate. 

Either way, what you need is some solid, practical tips to (hopefully) get your furnace cranking again—so you don’t have to put your kids to bed in their snowsuits. Even if you’re willing to do that, we’re guessing you’d rather not have almost frozen plumbing pipes.

Follow these tips to see if you can get your furnace to fire up again:

  • Make sure the furnace is turned on. “Well, is it plugged in?” seems like a ridiculous question—but given how many Columbia HVAC “repairs” involve flipping a switch, it’s worth asking. Check the thermostat to make sure it’s actually turned to heat, and then make sure the furnace itself is turned on and the breaker isn’t tripped.
  • Check your thermostat settings. Your thermostat tells your furnace when to turn on and off, so it’s worth having a look. Does it need fresh batteries? Did the schedule get changed somehow? Does it need a good dusting? Also, try setting the thermostat to five degrees above room temperature to see if your furnace kicks on.
    1. See if the furnace is getting power. Turn your thermostat fan switch from “auto” to “on.” If you hear the fan kick on, you’ll know the unit’s getting power. If the fan doesn’t come on, you have an electrical issue somewhere.
    2. Try cycling the power. We know, we know: “Turn if off and back on again” seems to be standard advice… but that’s because it (sometimes) works! Head to your thermostat, flip the switch to the off position, and wait 30-60 seconds. Then, cross your fingers, turn the switch back on, and see what happens. If that doesn’t work, temporarily set your thermostat to “beach weather” so it’s not trying to cycle your furnace on and off while you’re troubleshooting.
    3. See if the gas valve is turned on. Yes, yet another switch to check. If you have a gas furnace, it can’t get the fuel it needs to operate if the switch is off. 
  • Check your furnace filter.  This is one of the first things our technicians check, because homeowners are busy and don’t often think about their filters. Even a small amount of build-up can cause dirt to accumulate on the blower, which can cause the furnace to overheat and shut down. So, with the furnace switched off, pull your filter and check its condition. If you don’t see any visible debris, check for tears or holes. If the filter’s in any sort of rough shape, replace it. If you don’t have a spare on hand, gently vacuum any visible gunk from the filter, place it back in the unit, and try firing it back up. (And ask Alexa to order you some filters!)
  • Check the pilot light. If you have a gas furnace with a pilot light, see if it’s still lit. If it’s not? You guessed it: Simply re-light it. 
  • Close the blower door. If you recently did some preventive maintenance (gold star for you!), you may not have closed the blower door all the way. Your furnace won’t run unless that’s securely latched.
  • Check the air intake. Aaaand now you get to bundle up and head outside. Furnaces draw in air from the outside, warm it, and circulate it through your home. If the air intake is clogged by debris or snow, it will cause your furnace to overheat and turn off.

If none of these tips get your furnace running again—or if you’re just not comfortable trying to DIY your repair—we’re happy to help. Just give us a call.

I had a clogged drain that needed professional assistance. MasterTech was able to get Devin out to my house to fix our issue in record time. Devin was great and very professional and made sure the issue was fixed, the work area was clean and that I was satisfied with his work before he left. I highly recommend MasterTech.

When I called, the phone was answered by a pleasant service representative that remembered me and was understanding to my immediate need. MasterTech Plumbing tech Chad was very professional and friendly. He kept me informed of all what was wrong and didn’t try to up sell anything. I really appreciate Chad’s skillful knowledge. The quality of his work is exceptional. I know I can rely on Chad and MasterTech Plumbing.

Josh is great! He is the one who usually comes to our house. He installed an overhead tank toilet, which is a tricky and time-consuming job. He overcame many obstacles and stuck with it until the job was completed and done right. Price was also good. MasterTech has always taken care of all our needs in a prompt and professional manner. Emergency service has always been rapid too.

We had to have emergency service today, Saturday. A serviceman was here in less than an hour. The repairs were made quickly, the charge was not over the top, even though it was not a work day, and the individual was friendly and courteous. We have learned to expect this kind of service from Master Tech. Thank you.

I recommend MasterTech. They show up when they tell you they will show up. They provide a comprehensive estimate and also a good explanation of the work that need to be done. Their work is good quality. They usually have the needed parts on their truck so they can do the task in a timely manner. They clean up the work area after the job is finished,

A great experience. First, on time, service tech was sent out when promised. Second, quick assessment of the problem (faulty sump pump). The tech not only quickly replaced the pump, but he made an alteration that will make it easier whenever a replacement has to be made. Bottom line, a most professional service. Certainly would recommend Master Tech to folks needing their service.

MasterTech is so great to work with. They're quick, clean, do great work, and have fair pricing. But the best thing about MasterTech is their people. Whoever is responsible for their human resources does a terrific job of selecting and/or training them. They're so friendly and provide excellent information and customer service. I highly recommend MasterTech!

Previously I had not been impressed with master tech. However, their technician Dillon not only fixed my emergency pipe break at 1am on a holiday but also saved me as a customer. This was the best service I have ever had at my home. He arrived promptly at 1am. Provided a couple of options on how to fix my problem both in the short and long term and quickly made repairs. He also has provided advice on how to address issues related to the water damage caused by the busted pipe. This was one of the most positive bad situation we have had as homeowners. Thank you Dillon and mastertech.

I had to change my appointment at the last minute and they were able to accommodate my new availability without any hesitation. My tech was really professional (Dillion). I got a call and a text to let me know he was on the way. He fixed my problem quickly and was so friendly. This is the second time that I have had to use a plumber and I will use Master Tech again since I have an old house with old plumbing.
