Signs Your Furnace Is Not Heating Evenly

Posted On: November 28, 2024

Signs Your Furnace Is Not Heating Evenly

If your furnace isn’t heating your home evenly, it could indicate underlying issues that need attention. Uneven heating not only affects comfort but can also increase energy bills. Here are some common signs your furnace might not be heating evenly and potential reasons why:


1. Cold Spots in Certain Rooms

  • What it means: Some areas of your home remain cold while others feel adequately heated.
  • Possible causes:
    • Blocked or improperly adjusted vents.
    • Inadequate ductwork design or leaks.
    • An aging furnace struggling to maintain consistent output.

2. Inconsistent Airflow

  • What it means: Airflow from your vents varies across different rooms.
  • Possible causes:
    • Dirty or clogged air filters reducing overall airflow.
    • Issues with the blower motor or fan.
    • Closed or partially closed dampers in the duct system.

3. Thermostat Discrepancies

  • What it means: The temperature on your thermostat doesn’t match the actual feel in your home.
  • Possible causes:
    • A malfunctioning thermostat.
    • Poor thermostat placement (e.g., near drafts or heat sources).
    • Zoning issues if you have a multi-zone heating system.

4. Frequent Cycling

  • What it means: Your furnace turns on and off more frequently than usual.
  • Possible causes:
    • An oversized furnace that heats up too quickly.
    • Dirty sensors or faulty components causing short cycling.

5. Unusual Noises

  • What it means: Strange sounds like banging, rattling, or whistling occur when your furnace runs.
  • Possible causes:
    • Loose or damaged ductwork.
    • Problems with the blower motor or fan.

6. High Energy Bills

  • What it means: Your energy costs spike without a significant change in usage habits.
  • Possible causes:
    • The furnace working harder to maintain uneven heating.
    • Air leaks or poor insulation exacerbating inefficiency.

Solutions to Address Uneven Heating:

  1. Inspect and Clean Your Furnace: Replace air filters regularly and have the furnace professionally serviced.
  2. Seal Ductwork: Check for leaks or gaps in your duct system and seal them to ensure even airflow.
  3. Balance Vents: Adjust vent settings to redirect airflow to cooler areas.
  4. Upgrade or Replace Equipment: Consider upgrading to a zoned heating system or replacing an old, inefficient furnace.
  5. Schedule a Professional Evaluation: An HVAC technician can diagnose the root cause and recommend tailored solutions.

Addressing these issues promptly will not only improve comfort but also extend the lifespan of your furnace and save on energy costs.

by Eric Y, Greenbank on Twintech Heating and Cooling

Dave was great in helping me get the proper units for my property, as well as getting them installed. The installers arrived when they said they would, and completed the project on time, and professionally. If I needed another furnace, I would use Dave again.

by Ed B., Whitby on Twintech Heating and Cooling

I have known Greg and Grant Dainty for many years and have used their company for my house and business. I recommended them also for my parents and sister and they all have been very satisfied with the quality of work for a reasonable price. I just recently had them install a new HVAC system in an older house and was very pleased with their work. Craig in Pickering. After meeting with various heating and air conditioning contractors I was referred to Twin Tech Heating and Cooling through a family member. Greg and Grant arrived at my home and provided me with an estimate and a plan as to how they were going to remove and replace my furnace and air conditioner. On the day of install Greg and Grant arrived at my home on time and were very professional and extremely courteous as to any questions or concerns that I had. The removal and install was truly professional and the attention to detail was exactly what I was looking for. I’ve seen many installs from other contractors and I couldn’t be any happier to have had such a clean looking install. The sheet metal work, ducting and venting all look fantastic. Upon completion Greg and Grant left me feeling extremely happy and very fortunate of a job well done. Thanks again Twin Tech!!

My old furnace had finally broken down for the last time when contacted twintech to have a new furnace installed…They were prompt, knowledgeable and very reasonably priced. They did such a great job i tell all my friends and family about this company.

To whom it may concern, I recently had TwinTech (Greg and Grant Dainty) replace my furnace and service both my gas fireplaces and air conditioning unit. They were professional, courteous and very fair in their pricing. I would gladly recommend TwinTech to anyone needing work done. I can be contacted at 905-626-XXXX.

by Blair N. - Toronto on Twintech Heating and Cooling

My Fiancé and I have relied on Twintech Heating and Cooling now for the better part of the last 10 years. In that time, Greg has installed a furnace, an air conditioner, and a heat-pump at our residence in Toronto. In each instance Greg and his team were a pleasure to deal with. They were courteous and professional throughout the whole process and the quality of their work is first rate. Our experiences have always been extremely positive and we have referred his services numerous times to our friends and family. Without hesitation, I would recommend Greg and TwinTech Heating and Cooling to anyone looking to service or replace their existing heat/AC equipment

We are very happy to recommend this company to everyone. Our furnace broke down on Sunday morning. We phoned them and before noon Grant the owner showed up. He worked on the furnace for about a hour not wanting to give up to fix the problem. The furnace was 17 years old. I was the one talking about replacing it. End result was the next day it was all done. On the Sunday Bob came over with heaters to warm up the house. We decided to replace the water heater at the same time. Thanks Grant for the excellent work. Thumbs up.

by Linda on Twintech Heating and Cooling

Right on time. Explained how to work the HRV in a different way so the house would not be so dry. Changed my whole house water filter for me as well. Friendly, helpful, caring service!

by Robert Rogers on Twintech Heating and Cooling

Very pleased with the professional service that TwinTech Heating and Cooling provided in replacing my furnace. I got several quotes from different service providers. Their price was excellent and they explained the features very well. We are very glad we went with TwinTech and highly recommend their services.

by Robert Mizuno on Twintech Heating and Cooling

We were new homeowners in need of a second opinion. TwinTech Heating & Cooling were Amazing and professional. Very knowledgeable and great service all around. Recommend to anyone looking for honest and reliable services. Treated with respect and care. Thank you Greg, Mitch and Bob!

by Ruth on Twintech Heating and Cooling

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 did not need a new furnace. TwinTech did not push to make an unnecessary sale and saved me from a huge expense. Bob and Mitch were extremely professional and above all honest! I definitely recommend TwinTech!
