Common Furnace Problems We Repair
Most furnace issues start with a symptom you can feel: no heat, weak heat, high energy bills, strange noises, or a furnace that never seems to stop running.
Common causes include:
- Dirty or clogged filters that restrict airflow and strain the system
- Faulty thermostats that keep the furnace from reading the home correctly
- Weak airflow caused by blocked vents, duct issues, or blower problems
- Ignition issues that prevent the furnace from starting
- Dirty flame sensors that cause the system to shut off too soon
- Blower motor problems that keep warm air from moving through the home
- Blocked vents or registers that make certain rooms harder to heat
Many of these problems can be repaired without replacing the entire furnace. CAP Heating & Cooling identifies the cause and recommends the fix that makes the most sense.
Furnace Not Working?
Start With A Clear Diagnosis
CAP Heating & Cooling starts by identifying the source of the issue. Then we make the repairs needed to get your heating system working again, improve performance, and help your home feel comfortable.
1. We start with what you’re noticing.
No heat. Weak heat. Cold rooms. Short cycling. Strange noises. Burning smells. Higher energy bills.
2. We inspect the furnace and controls.
We check the thermostat, ignition system, flame sensor, blower motor, safety controls, and visible furnace components.
3. We check airflow and filtration.
We look at the filter, vents, registers, and airflow problems that can make your furnace work harder than it should.
4. We explain what’s happening.
You’ll understand whether the issue is a repair, a maintenance problem, or something more serious.
5. We make the right fix.
Our goal is to get the heat back on, improve performance, and help your home feel warm again.
Can Dirty Filters, Dust, Or Airflow Problems Affect Your Furnace?
Your furnace doesn’t work alone. It relies on clean airflow moving through filters, vents, and ductwork to heat your home efficiently.
Excess dust is one of the most common contributors to furnace wear, reduced performance, and mechanical failure.
When filters are dirty, vents are blocked, or ductwork is full of buildup, your furnace has to work harder than it should.
Dirty Filters
Most
furnace filters
should be changed every 30 to 60 days for the best results. Regular filter replacement helps protect your system, improve airflow, and support better indoor air quality.
Dust & Debris Inside Ductwork
Air ducts should typically be cleaned every three to five years. If you have pets or recently completed a renovation project, more frequent cleaning may make sense.
CAP’s duct cleaning systems use HEPA filtration that captures 99.9% of contaminants in our vacs and negative air machines.
The Advantage Of Looking At The Whole System
CAP Heating & Cooling looks beyond the furnace itself. We consider the equipment, filters, ductwork, and airflow together to identify what’s affecting heat, efficiency, and the air you breathe.

Commonly Asked Questions from Medford Homeowners
Why is my furnace running but not heating my house?
One of the most common furnace issues. Causes can include thermostat problems, dirty filters, ignition issues, restricted airflow, or failing components, all of which require professional diagnosis.
Can a dirty air filter cause furnace problems?
Yes. A clogged filter can restrict airflow, force your furnace to work harder, and even cause overheating or system shutdowns. Replacing filters regularly is one of the simplest ways to support furnace performance.
Why are some rooms in my house colder than others?
Uneven temperatures can be caused by airflow restrictions, ductwork issues, blocked vents, dirty filters, or HVAC system performance problems. A professional inspection can help identify the root cause.
How often should a furnace be serviced?
Most manufacturers and HVAC professionals recommend annual furnace maintenance. Regular inspections can help identify worn components, improve efficiency, and reduce the likelihood of unexpected breakdowns during the heating season.
