Is My Furnace Acting Up?

Posted On: November 22, 2024

Is My Furnace Acting Up?

If your furnace isn't functioning as it should, it can be frustrating and potentially costly, especially during colder months. Here are some signs your furnace may be acting up, along with possible causes:


1. Inconsistent Heating

  • Sign: Some rooms are colder than others, or your home isn’t reaching the set temperature.
  • Possible Cause: This could be due to dirty filters, a malfunctioning thermostat, or blocked vents. In some cases, your furnace might be too small for your home.

2. Unusual Noises

  • Sign: Banging, clanking, or whining sounds.
  • Possible Cause: Noises often indicate loose components, a failing blower motor, or ignition issues.

3. Frequent Cycling

  • Sign: The furnace turns on and off more often than usual.
  • Possible Cause: This might be caused by a dirty filter, a miscalibrated thermostat, or airflow restrictions.

4. Increased Energy Bills

  • Sign: Your energy bills are higher than normal without any changes in usage.
  • Possible Cause: A furnace struggling to heat efficiently often uses more energy. This could be due to worn-out parts, poor maintenance, or old age.

5. Poor Air Quality

  • Sign: More dust, dander, or dryness in your home.
  • Possible Cause: A dirty furnace filter or ductwork may be circulating contaminants, or your system may not be properly humidifying the air.

6. Pilot Light Problems

  • Sign: The pilot light is yellow instead of blue.
  • Possible Cause: A yellow flame may indicate poor combustion or a carbon monoxide issue. This is a safety concern and should be addressed immediately.

7. Strange Smells

  • Sign: Burning, musty, or chemical odors.
  • Possible Cause: A burning smell might mean dust is burning off, but persistent odors could suggest electrical issues, gas leaks, or mold in the system.

What to Do Next

  • Check Basic Issues: Replace the filter, check the thermostat settings, and ensure vents are open.
  • Call a Professional: If basic troubleshooting doesn’t resolve the issue, contact a licensed HVAC technician. They can inspect, repair, or replace your furnace if necessary.

Keeping your furnace well-maintained can prevent many of these issues. Schedule regular tune-ups to ensure your system operates efficiently and safely!

End to end service. From quote, overseeing installation, contacting and making arrangements for energy audit. Warranty program is comprehensive. Cleaned up mess of assistant walking through my place without proper indoor foot covering when I pointed out that I was not happy about footprints on my floors.

by Bob S in Pickering on Twintech Heating and Cooling

In April we hired Twintech Heating & Cooling to replace our 20 year old water tank & 35 year old air conditioner. We got 5 estimates for the job & decided to go with Twintech for the following reasons.

- The Sales Manager, Dave, was very personable & knowledgeable as all of our questions were answered. (We had a list of questions we asked each of the contractors when we got the estimates)
- We got 5 estimates for the job. All contractors verbally told us they had the required qualifications but Dave was the only one to physically show us their license & insurance documentation.
- Twintech carried the Napoleon air conditioner & we wanted to support Canadian industry as it is assembled in Barrie On.

Safety is important at Twintech as demonstrated when we discussed with Dave, the need to change our install date because of freezing rain. Access was required by navigating a set of outside steps & Dave identified that safety took precedence.
On the installation date, Greg, Peter & Grant showed up on time & methodically accomplished the removal & installation of both units. The guys did a great job cleaning up as well.

When the job was completed we mentioned to Greg that we were pleased with the work they had done & were going to have them come out & do our furnace inspection in Sept. Greg said we can save our money as he had inspected the heat exchanger on the furnace while doing the job & there was no need to have another inspection in Sept. We were very impressed with Greg’s initiative. This is top shelf service. Thank you Greg.

As the weather was too cool to complete a functional test of the air conditioner on the installation date, Dave made a follow-up call to us to see how things were going & Greg also came out to check the operation. No problems.

We are very happy we hired professionals like Dave, Greg, Grant & Peter & have no hesitation in recommending Twintech Heating & Cooling. They will now be our "go to" guys.

These guys are the best. From start to finish they exceeded my expectations and delivered a great product. They accommodated the nuances of my 100 year old home which was really appreciated. The install was easy to schedule and done fantastically. I’m so excited to have an efficiently heated and cooled home.

by Private User from Kitchener on Twintech Heating and Cooling

Twintech were fast and efficient contractors. It only took 48 hours between an initial home visit and complete installation. The workmen were polite and hardworking. The site was left clean with the old furnace etc. removed. They helped arrange an environmental assessment in order that I could receive the maximum rebate. They even called me within a week to determine if I was satisfied with their work and to reassure me that I could call them anytime I experienced heating difficulties or had any questions. I recommend Twintech for your heating problems.

by dlcarroll in Vaughan on Twintech Heating and Cooling

Courteous and professional service from initial consultation through to the installation. We highly recommend Twintech for outstanding service in the industry. Competitive pricing, professional and accurate advice, attention to detail, respect for their client's home and cleaning up at the completion of installation.

by TraceyG from Toronto on Twintech Heating and Cooling

Last night was the coldest day of the year so far and I woke up to my house being 54 degrees... I called Twintech at 2:45am and Greg was on site by 3:30am. The furnace required a part and he returned to his shop and came back to my home around 4:15am, furnace up and running by 4:30am. THANK YOU TWINTECH! Your service is second to none.

by Cristelle from Ajax on Twintech Heating and Cooling

After much research & getting 4 quotes, we hired Twintech team for our new furnace installation, prices were fair, they carried great product brands & more importantly installation was expertly done by one of the owners (Greg & his assistant Peter) which gave me an added piece of mind. Dave was very organized & answered all my questions in great detail, especially re: the Enbridge & Govt. rebate program.

by David from Pickering on Twintech Heating and Cooling

My old air conditioner was 20 years old and developed a Freon leak and it was more cost effective to replace rather than repair. There are a large number of heating and air conditioning companies available in my area so I contacted several for quotes. Twintech heating and cooling responded quickly to the inquiry I left on their website and their sales person Dave came by the following day. He was knowledgeable about the field and was able to show copies of the various refrigeration and gas fitting licenses along with workmens compensation, TSSA and other certifications. He also suggested a particular manufacturer and model of AC unit appropriate to my house and gave me a quote. Since the price was reasonable, service had been good and the reviews on the internet were also good, I decided to purchase an AC unit from them. Installation was quickly scheduled. They showed up on time, did a good job installing the new unit including some sheet metal work to get the new heat exchanger to fit in the furnace duct, and cleaned up afterward. In addition, they noticed that my existing AC was installed too close to the furnace exhaust (based on building code) and were able to mount the new AC the appropriate distance from the exhaust. Overall, they did an excellent job and were a pleasure to work with.

by LP from Pickering on Twintech Heating and Cooling

All interactions from sales to installation were Courteous and professional. The installation was seamless and the attention to detail including clean up was outstanding. I highly recommend TwinTech Heating and Cooling.

by David in Pickering on Twintech Heating and Cooling

Twintech's Salesman Dave arrived promptly was friendly and courteous, listened and assured us the installation would be completed according to our requests. The crew arrived early morning on May 11th, 2018 and worked through till late afternoon non-stop. They were very friendly, very professional, their expertise was excellent, their workmanship outstanding and the installation was completed in a timely and efficient manner. We were completely satisfied and happy with the quality of the work.

TwinTech is an excellent and honest company! I called them for a second opinion after being told by another company that I needed to replace my furnace. Turns out this was not the case at all!

I definitely recommend TwinTech!
