There are a lot of factors that don't include your furnace that could be preventing heat from getting to all rooms in the home and that affect your comfort. If some of the rooms throughout the house are hot and some of them are cold, and you can't get consistent heat around the property, the problem may not be the furnace itself but instead the ventilation system. You need to call a licensed heating and cooling professional and ask about the following things to get to the bottom of the problem.
Open Vents and Blocked Cold Air Returns
The vents that deliver heat throughout the house can sometimes get closed. Not only will this make a room cold, but then more air goes to other areas and it can make other areas hot. If you don't realize that a vent is closed, because it's in a room you don't go in or it's a vent that isn't easily managed, this could be the source of the problem.
The same situation can occur with a cold air duct return. If the cold air can't pass and move throughout the house, this can cause a lot of issues as well because the air can't travel as needed. You could have heat jam somewhere in the ducts.
Dirty Duct Problems
You don't want to have dirty duct problems in the home or clogs in the ducts. When you have dust, dirt, clogs, and other concerns, the following issues should be considered:
- Poor air quality because of pollutants in the air
- Airflow problems and blocked air
- Fire hazard
- Dry air
Talk with the HVAC professionals about having the ducts cleaned well to check for problems and to clean the air that flows throughout the house.
It's recommended that you have your filters changed and your furnace tuned up on an annual basis, and your filter may need to be replaced more often than that. Have the furnace inspected while it is maintained and cleaned to see if there are problems causing airflow or heat inconsistencies in the living space.
If your house is hot and cold and it is uncomfortable to be in different areas because of the temperature changes, it's time to get an expert to the property so you can see what is going on. You don't want to end up with a heating problem that leaves you sweaty or chilled. Ask your local HVAC contractor about heating repairs to learn more information.
