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.

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. I highly recommend Twintech for your cooling or heating needs. They stand by their products and a pleasure to deal with.

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.
