Why Isn’t My Furnace Heating My Entire Home?
If your furnace seems to be producing heat inconsistently around your Sequim home to you, you’re not alone. Many homes have varied conditions from room to room, causing spotty heating or cooling.
On cold days, this can be a nuisance. You may be confined to only a few rooms in your home, or you might have to wear a coat and blanket just to function around the house.
Our team at Air Flo Heating Co wants you to be comfortable at home—you deserve to be! There are several reasons why your furnace may not be providing adequate warmth. Common issues include a malfunctioning thermostat, clogged air filters, or even more serious problems like a broken blower motor or a faulty igniter.
Understanding the potential causes of your furnace’s heating issues is the first step in getting your system back on track.
Why Isn’t My Furnace Heating?
Here are some of the most common reasons why furnaces stop heating effectively and guidance on what you can do to restore warmth to your home. Whether it’s a simple fix or a sign that you need professional help, being informed will help you make the right decisions for your heating system and ensure your home stays comfortable.
1. Poor insulation
If your ducts, windows, attic, or walls have poor or nonexistent insulation, you might have a problem. Heat is escaping, which can cause inconsistent heating. However, you can fix this relatively quickly.
Your heating, ventilation, and air conditioning (HVAC) professional can perform a thermal analysis in order to figure out which areas need insulation. A professional can install insulation within hours, and compared to other home improvements, it is relatively affordable.
2. Duct problems
Leaky or blocked ducts can lead to patchy heating. The insides of your ducts can have blockages, especially if they haven’t been cleaned recently. Leaks in your ducts are another enemy of even heating. If you think you might have leaky or blocked ducts, have a trained technician perform a thermal analysis and duct cleaning or repair.
Also, take a walk around inside your home to see if any registers or intake vents are being blocked by furniture or carpeting.
3. Thermostat problems
Try changing your thermostat settings. If your furnace is set to Auto, change it to the On setting. This will cause it to run consistently instead of incrementally, which may lead to more even heating.
Your thermostat might also have heat sensor issues or faulty wiring, which causes it to produce the wrong temperature reading. A professional can diagnose this issue.
4. Improperly sized furnace
When a furnace is sized incorrectly for your Washington home, it will usually produce poor heating. Undersized units lack the capacity to ventilate your entire living area.
Similarly, larger units short-cycle, leading to inadequate heating. One of our experts can perform heat load calculations to determine whether your system is the correct size.
5. Lack of maintenance
When you don’t schedule routine maintenance visits, your system can lose its finesse. Dirty coils, worn/unsecured belts, and clogged filters are common mishaps. Due to these issues, you’ll have a weakened heating system.
Routine maintenance saves you money. You can reduce your energy costs by up to 30 percent with seasonal tune-ups and professional maintenance. Regular HVAC maintenance can also reduce costly breakdowns by as much as 95 percent.
6. Wrong-sized filter
Good airflow is key to dispersing hot air throughout your Sequim home. If your filter is too thick for your furnace, it creates excessive resistance, leading to compromised airflow. You can have your technician perform a static resistance test to see if it’s the right size.
7. HVAC zoning
Some homes have varied heating needs for different rooms. Fortunately, with a zone control system, you can adjust the temperature settings in multiple areas. If you live in a home with multiple stories, large windows, or a furnished basement, zone controls may be the best solution.
