Why is My Furnace Not Heating Properly?
Posted On: October 29, 2023
However, here are some common reasons why a furnace may not be heating properly:
-
Thermostat Settings:
- Check if the thermostat is set to the desired temperature.
- Ensure that the thermostat is set to the "Heat" mode.
-
Clogged or Dirty Filters:
- A dirty or clogged air filter can restrict airflow, reducing the efficiency of the furnace. Replace or clean the air filter regularly, typically every 1-3 months.
-
Pilot Light/Ignition Issues:
- If your furnace has a pilot light, ensure it is lit. For newer models with electronic ignition, check for error codes or ignition issues.
-
Gas Supply Issues:
- Verify that the gas supply to the furnace is turned on. If you suspect a gas supply issue, contact a professional immediately for assistance.
-
Thermocouple Problems:
- A faulty thermocouple may cause the gas supply to the furnace to be shut off. This is a safety feature to prevent gas leaks. A technician can check and replace a faulty thermocouple.
-
Burner Issues:
- Dirty or malfunctioning burners can affect the heating efficiency. If the burners are not lighting or staying lit, it may require cleaning or adjustment.
-
Blower Motor Problems:
- If the blower motor is not working correctly, it can result in inadequate heat distribution. Check for unusual noises or lack of airflow.
-
Ductwork Issues:
- Leaks or blockages in the ductwork can reduce the efficiency of your furnace. Inspect the ducts for any visible issues.
-
Dirty or Blocked Vents:
- Ensure that all vents and registers are open and not blocked by furniture or other obstacles. Clean any dust or debris around the vents.
-
Electrical Issues:
- Check for tripped circuit breakers or blown fuses in the electrical panel that powers the furnace.
If you have checked these common issues and your furnace still isn't functioning properly, it's recommended to contact a licensed HVAC professional to diagnose and address the problem. Working with gas appliances and furnaces can be dangerous, so it's crucial to prioritize safety and seek professional assistance when needed.

On coldest night of the year our furnace quit. At 8:40 in the morning Greg arrived and gave us a diagnosis and a recommendation. By 2:30 we had a new furnace and were warm again. Great company. Great customer service. Good reasonable price.

Twin tech team was very efficient and prompt. They provided a quote within hours of request and got the job done on time. No disruption to home function. We would highly recommend this team. Job well done.

Our furnace bit the dust, and Twintech came out to troubleshoot and diagnose the problem within a couple of hours. Mitch was super helpful, patient, and answered all of our questions. When we decided to get the furnace replaced, the crew was over first thing the next morning and did a fantastic job. Not only did they complete the job in a few hours, but they cleaned up and respected our house as they went, and answered all of our follow-up questions. I've used Twintech for our HVAC needs in the past and will continue to do so. I'd recommend them to anyone, and it feels good to support a local, family-owned business.

Dave and the Twintech team were fabulous from day 1 and helped us through the process to identifying a new furnace and AC unit. This was our first time through this process and Dave did a thorough job explaining all the components and was very patience answering all our questions. Dave provided great insights and fair pricing.
The Twintech team did an awesome installation. Very clean and efficient. I would highly recommended their service.

We had a new Amana furnace installed by Twintech and we were very pleased with the installation. It is nice to have a warm house again.

Excellent job. Excellent service. Competitive price. Its rare to find a company with the knowledge and professional results we have experienced with Twintech. The clean and neat installation with attention to detail and drop sheers to respect our property is a clear indication of Twintechs high level of integrity. The 1-1/2 gas line upgrade they did for our pool 3 years ago was awesome. Can't say enough. Thank-you Twintech.

Twitch did a great job with the installation of our new furnace. I really appreciated their honesty and I could trust what they were telling me. Another company tried to suggest significantly more work at a greater cost claiming it was necessary to meet current building code. Twintech is very fair. All staff I meet were friendly, polite and trustworthy. I would recommend Twitch for a furnace.

This is a professional team that's easy to deal with. I would strongly recommend them

Very professional firm from start to finish!
They removed the old oil tank and furnace. They installed air conditioning and a new propane furnace.
Professional installation, on time and no mess.
Very pleased with their work and would highly recommend the company. Our house is three stories so they spent the time to do all the calculations to make sure we would have great performance on each floor.
Thank you again!

Upon a routine yearly maintenance, it was discovered there was a leak in the heat exchanger and a I needed a new furnace. I know nothing about these things and was completely stressed out. The company I had the maintenance plan with quoted me a huge number to rent a furnace, I just wanted to cry. Then I spoke to Dave at Twintech. He was so knowledgeable and calming, provided me a fair quote and within a few days I had an amazing crew show up to my house and install my new energy efficient furnace! I have already recommended these wonderful people at Twintech to a good friend of mine. Thank you Twintech!!
