Is My Furnace Heating Unevenly?
Posted On: February 4, 2025
If your furnace is heating your home unevenly, it could indicate a problem with the system or other factors affecting heat distribution. Here are some common causes and potential solutions:
1. Clogged or Dirty Air Filters
- Cause: A dirty filter restricts airflow, making it harder for warm air to circulate evenly.
- Solution: Replace or clean the air filter regularly (every 1-3 months).
2. Blocked or Closed Vents
- Cause: If vents are blocked by furniture, rugs, or other objects, airflow can be disrupted.
- Solution: Make sure all supply and return vents are open and unobstructed.
3. Thermostat Issues
- Cause: A malfunctioning or poorly placed thermostat (e.g., near windows or heat sources) can cause uneven heating.
- Solution: Check the thermostat settings and placement; consider upgrading to a programmable or smart thermostat.
4. Ductwork Problems
- Cause: Leaky, disconnected, or poorly designed ductwork can lead to heat loss and uneven distribution.
- Solution: Inspect the ducts for leaks or damage and seal them with duct tape or mastic sealant. A professional HVAC technician can help if the ductwork is severely damaged.
5. Furnace Size and Age
- Cause: An undersized furnace may struggle to heat your home evenly, while an oversized unit may short-cycle, leading to uneven temperatures.
- Solution: Have an HVAC professional assess whether your furnace is appropriately sized for your home.
6. Insulation and Drafts
- Cause: Poor insulation or drafts around doors and windows can cause some rooms to be colder than others.
- Solution: Add insulation where needed and seal gaps around windows and doors.
7. Zoning Issues
- Cause: Larger homes may have difficulty maintaining even heat if there’s no zoning system.
- Solution: Consider installing a zoning system or using space heaters in problem areas.
If you're still experiencing uneven heating, it may be best to have a professional HVAC technician inspect your system.

On one of the coldest days of winter, our furnace stopped working. Our regular furnace company came and told us we had a CO2 leak and shut us off. Their quote for a new furnace was way too high and they couldn't even install it on the same day. TwinTech was recommended to us by a friend. We called and spoke to Dave who was very nice and knowledgeable. Grant showed up a short time later and a new furnace was installed the same day with no troubles at all. Best of all, we received a higher-end furnace than what was offered by our previous company and at a cheaper price. I would recommend TwinTech with no hesitation at all.

Great sales member named Dave came in told us some amazing items and how they would be priced installed an all. We couldnt believe it! The next day the ac was installed, that day one employee named Greg told us that our furnace was working way to hard and was causing us to use way too much gas. So two days later they came in an installed a new furnace!

They removed and discarded old furnace. Installed new furnace. Installed air intake pipe, that had never been installed by builder, no charge. Replaced loose hose on floor with hard pipe and rerouted it to drain, no charge. Almost 33% cheaper then quote from Enercare, which was the company we dealt with and had insurance with for 8 years. No yearly fee for cleaning/insurance, saves 300 a year. Courteous, professional, fast, and friendly. My wife and I have been recommending them to everyone we know and meet, and will continue to do so. Thanks for everything, Twintech!!!

Finally! An honest company with highly knowledgeable and informative staff. Had a furnace service and found multiply errors in our system from an amateur installer. Very fair price to correct problems and will definitely use again.
