When addressing internal furnace issues, it's important to recognize common problems and their potential causes. Here’s a breakdown of some key internal furnace issues and how they can be resolved:
1. Clogged or Dirty Filters
- Cause: Filters trap dust, dirt, and allergens, but when they become clogged, it restricts airflow.
- Effect: This can cause the furnace to overheat, reduce efficiency, and increase energy bills.
- Solution: Regularly replace or clean filters every 1-3 months.
2. Ignition or Pilot Control Issues
- Cause: Problems with the ignition system (electronic ignition or pilot light) can prevent the furnace from properly heating.
- Effect: This can result in intermittent heating or the furnace not starting at all.
- Solution: Check for loose connections, gas flow issues, or malfunctioning pilot controls. If unsure, consult a technician.
3. Blower Motor Malfunctions
- Cause: The blower motor pushes warm air through the duct system, but wear and tear or dust buildup can affect its performance.
- Effect: The furnace may run but won’t circulate warm air properly, leading to cold spots in the home.
- Solution: Have the motor cleaned and serviced regularly. In some cases, the motor may need replacing.
4. Limit Switch Failure
- Cause: A malfunctioning limit switch can prevent the blower from turning off, causing the furnace to overheat.
- Effect: This not only increases energy usage but also poses a safety risk.
- Solution: Have the limit switch tested and replaced if necessary.
5. Cracked Heat Exchanger
- Cause: Over time, the heat exchanger can crack due to stress and temperature fluctuations.
- Effect: A cracked heat exchanger can leak carbon monoxide, a dangerous and potentially lethal gas.
- Solution: If a crack is detected, the heat exchanger must be replaced immediately.
6. Thermostat Malfunctions
- Cause: A faulty thermostat may fail to communicate with the furnace, leading to improper heating cycles.
- Effect: The furnace may not turn on or off at the desired temperature.
- Solution: Check thermostat settings, replace batteries, or consider upgrading to a programmable model.
7. Dirty Burners
- Cause: Burners that are dirty or misaligned can cause inefficient combustion.
- Effect: This reduces heat output and can lead to safety hazards like gas leaks or carbon monoxide emissions.
- Solution: Have a professional clean and inspect the burners.
8. Frequent Cycling
- Cause: If the furnace frequently turns on and off, it may be due to improper airflow, thermostat issues, or an oversized unit.
- Effect: Frequent cycling reduces efficiency and puts additional wear on furnace components.
- Solution: Address airflow problems, check thermostat calibration, or consult an expert to ensure the furnace is appropriately sized.
Conclusion
Preventative maintenance and regular inspections can help avoid many of these internal furnace issues. Scheduling annual furnace tune-ups will ensure your system runs efficiently and safely, especially during peak usage seasons.

They've cleaned my furnace a couple of times and mentioned that the hot water tank standards were going to change soon so I decided to change mine out.
There were a few challenges during the process but the installers handled the problems without missing a stride! I now have really hot water again!

Customer service and knowledge is priority in this industry, and Twintech has it. I've dealt with their team for maintenance and a furnace replacement. They're accommodating and make great recommendations, and came through at a great price over the big guys in the industry. They'll be my next call when I need service or maintenance.

I decided that the noises and age of the existing furnace which was old and not very efficient to replace it. Gave Greg a call and Grant and Greg got to work on it. Because of supply issues with the current heating type that would be an easier install Greg convinced me to change the location of the system and it would provide me better service for heat and efficiency. I had skeptical but went ahead anyway putting trust in Greg And Grant. Greg, Grant and Mitch came through and in 2 days had completely relocated my heating and A/C system. I can honestly say Greg was right my old house has been warmer and more evenly heated as it ever was. For anyone reading this rather long winded review can take my word for it, Twin Tech can take care of your needs.

I called Twin Tech when my air conditioning stopped working. Greg came over to diagnose the issue - the same day. He was able to diagnose the issue and resolve it quite quickly. Although it was a quick fix, Greg was very thorough in explaining the issue and provided great advice. Not to mention, I felt very comfortable having Greg in my home - which I consider very important when hiring a service provider. Twin Tech will be my go-to from now on. Thank you!!

Great Team! Furnace broke in the weekend, Bob visited same day and Greg installed new one on Monday. Team was professional, respectful and knowledgeable. Installation went very well, Greg found solutions to challenges, like hiding new conduits in the ceiling. Looks nice and new furnace is working great. Five Stars.

I used Twintech to install a new furnace for my home. Bob was terrific in explaining the sizing options and why the 2 stage furnace was the best option for me. Greg did a great job installing, clean and on time. Finished work looks great but the best part is how it works. The 2 stage heating is so much more comfortable. I run the fan continuously to keep the indoor air clean. Great investment! Would highly recommendTwintech!

Im going to start this by saying Im a very particular customer. My background is in mathematics and mechanical engineering so I have an eye for detail and a respect for technical knowledge.
Greg had already done an AC inspection and replaced a water heater tank and there was no question in my mind who to deal with replacing my rickety old furnace after it got pooched.
Bob dropped in ahead of time and clearly (and knowledgeably) outlined all technical, price and operational options.
Greg showed up on time, on the agreed date and did a fantastic job. (The OLD furnace was a house of horrors and was installed in a keystone cops sort of way- careless.)
The work Greg did was HIGHLY PROFESSIONAL and FAR MORE FUNCTIONAL than what I had.
Im also a musician with many instruments so maintaining predictable humidity/temperature is extremely important to me. Greg recognized this as did Bob. You NEVER feel like youre being brushed off.
In summary, if youre looking for PROFESSIONAL, QUALITY results by an EXPERIENCED, THOUGHTFUL team
(that also happen to be FRIENDLY and ATTENTIVE ) then youve come to the right page!!

A young man by the name of Mitch came by tonight and he was so nice explained everything he was quick he was clean he turned off the lights even when he left the furnace room its just above and beyond Twin Tech always delivers and I just found out about them last year and I will use no one else but thanks again Mitch you are fantastic

I had a problem with the Furnace (Armstrong ultra V) and Greg diagnosed it on the phone. Even told me what the issue was and I was able to fix it. This level of service from a Business that is almost unknown today.
If you require service, reach out to Greg. I will definitely use them in the future!
