Should You Call a Technician? Diagnose Furnace Repair Issues in 5 Easy Steps

Having a professional check your furnace at the earliest sign of malfunction can save you a lot of time, money, and complex repairs down the road. Here are some helpful tips on how to tell if it’s time to call a technician:

1. Check the Power 

If you’re experiencing furnace issues, the first thing you should do is check whether the furnace has power. If it doesn’t, you may be able to fix the issue yourself. 

If you have easy access to the breaker box, take a look to check that all switches are in the right direction. Someone may have accidentally turned them off, or a fuse may have blown. If so, a simple reset to the main furnace unit could be all you need to get the system back to proper function. However, be careful not to touch or mess with any of the electrical connections.

If your furnace keeps blowing its fuse, it may have loose wires or faulty parts that our team can rectify. 

2. Check the Thermostat

Next, check the thermostat. Is it working at all? Is it dialed in to the right settings, or has it switched modes accidentally? Digital thermostats can sometimes reprogram their settings without you realizing it, or your thermostat may have lost connection with the heating system.

In any case, try turning the thermostat up a couple of degrees to see what happens. If you aren’t sure how to change the settings and don’t have the thermostat manual at hand, you can find it online for free by looking up the make and model of the appliance.

Keep in mind that most modern thermostats have battery-powered digital components. Remove any old batteries and replace them with new ones to check if that changes anything. Make it a habit to replace all batteries twice a year — preferably, at the start of the summer and the start of the winter — to prevent common malfunctions.

3. Check the Pilot Light

If the thermostat seems to be working properly but the indoor temperature continues to drop, it’s possible that the furnace isn’t turning on at all. This often indicates a pilot light or electronic ignition issue.

Check to see that the pilot light is on. If the light is flickering or completely off, call a technician as soon as possible. You may also need to get a new thermocouple. A faulty pilot light will cause your furnace to work harder, resulting in unnecessary wear and tear and inflated energy bills.

4. Check the Air Filters

Air filters are critical to heating function. A clogged or dirty filter can create a draw on the furnace, causing damage to the unit and a decrease in indoor air quality. You should change air filters once every three months to ensure optimal furnace performance. If you are having difficulties locating or changing the filters on your own, our experienced technicians would be happy to help.

If none of the steps above seem to help, it’s time to call our experts at 888 Heating and Air Conditioning. We’ll inspect, diagnose, and fix your furnace in no time. Our technicians will arrive in fully stocked trucks with all the equipment they need to resolve most common furnace issues on the spot.

Furnace Repair in Denver FAQ

Read the answers to common questions we often hear in our practice:

It’s always best to call us as soon as you detect any glitches, but especially if you smell gas or see a yellow flame in the furnace.

All gas leaks are potentially deadly, so be sure to turn off the thermostat, get out of the house, and give us a call immediately. You should also call your local gas company to turn off the gas.

Likewise, a yellow burning flame (instead of blue) could be an indication that the gas isn’t burning properly and may be emitting carbon monoxide.

You should also call us right away if temperature changes are causing the heat exchanger of your furnace to crack. Even a miniscule crack can result in carbon monoxide seeping into your home.

Our technicians are trained in diagnosing and stopping gas and carbon monoxide leaks and fixing all types of gas furnaces. We also run a carbon monoxide check as standard protocol with every visit to ensure that your furnace is up to code. If you suspect a dangerous leak, call us right away — we offer emergency services six days a week during our extended business hours at no extra charge.
