Simple Troubleshooting For Your Furnace
Posted On: October 1, 2024
Here’s a straightforward guide for troubleshooting your furnace:
1. Check the Thermostat
Ensure your thermostat is set to “heat” and the temperature is higher than the current room temperature. If it's battery-operated, check the batteries as well.
2. Inspect the Furnace Switch
Locate the power switch, which often looks like a regular light switch near your furnace, and make sure it’s in the “on” position.
3. Check the Circuit Breaker
If the furnace isn’t turning on, check your home’s electrical panel for a tripped circuit breaker. Reset it if necessary.
4. Change the Air Filter
A clogged filter can restrict airflow, causing your furnace to overheat or not work efficiently. Replace it if it’s dirty or clogged.
5. Ensure Proper Airflow
Make sure that your air vents are open and not blocked by furniture or other items. Proper airflow is key to keeping your furnace running smoothly.
6. Inspect the Pilot Light or Ignition System
If your furnace uses a pilot light, ensure it’s lit. If you have an electronic ignition system, check the furnace manual for reset instructions.
7. Check for Gas Supply
Ensure the gas valve to the furnace is open. If you smell gas, turn off the furnace immediately and call a professional for assistance.
8. Examine the Furnace Flame
If the flame is yellow or flickering instead of blue, this could indicate a problem with combustion. Call a professional if this occurs.
9. Look for Error Codes
Many modern furnaces have a diagnostic system that will flash error codes if something’s wrong. Check the manual to decode any lights or beeps.
10. Call a Professional
If these steps don’t resolve the issue, it’s best to call a certified technician for a more thorough inspection and repair.
Regular maintenance, such as cleaning the furnace and replacing filters, can also prevent many of these issues from arising.

Reasonable price and the workmanship was prompt and timely and the employees were great to deal with.
May 2, 2020
The sales process was friendly, informative, and very consultative. They worked hard to earn our business by taking a careful look around our home to assess our needs, providing a lot of information about the product, and answering all our questions and finding the right solution for our home at a competitive price. They prepared us very well for what to expect on installation day, and the installation went very smoothly - no surprises, all very professional! They gave us a call after installation to ensure we were happy with the work. We're very happy that we chose to work with TwinTech to get our new furnace.

When our old oil furnace finally broke down we decided it was time to finally convert to natural gas and finally install central air conditioning at the same time. Knowing it was going to be a significant investment for us, we wanted to make the right choice. Twintech came highly recommended by a friend and we were not disappointed. From the first contact with the salesperson, until the final touches on the installation, we were so pleased with their service. Everyone from the company was so friendly, efficient and a pleasure to deal with. Best of all, the cost was very competitive. We would certainly recommend Twintech to anyone requiring HVAC work in their home.

Mitch from Twintech came out for our annual furnace inspection. We found him to be friendly, conscientious & he left the work area clean. We were also very impressed with the thoroughness of the job he did. This is the 2nd job weve had Twintech do for us & have been very happy with the results for each. We highly recommend this company. Thank you, Mitch, Dave & Greg.

Work was done on schedule, professionally, according to quote and with minimal inconvenience to building users. Very happy with the end result. The only area for improvement from my experience - need more timely quoting process.

The team was great! Very knowledgeable, professional and extremely helpful. A few days after install the unit didnt seem to be working, user error, but within minutes of contacting them..on a Saturday.. a tech was on the phone troubleshooting with us.

During the hottest week in the summer our old A/C decided to call it quits. I called Twintech Heating & Cooling after receiving a referral from a family member; came highly rated for being an honest, family-run business, who appreciates their customers. Dave was able to accommodate my hectic schedule and book a late evening appointment to walk through the specifics. Greg and Mitch arrived exactly on time a few days later, were very polite and friendly, and within a couple of hours had a new unit up and running. I also received a follow-up call to ensure we were happy with the Amana.
