Common heating problems — causes and fixes
Furnace won’t start
Cause: Faulty thermostat, power issues, or ignition problems.
Fix: A technician will verify power and thermostat settings, test ignition and safety switches, and repair or replace faulty components.
Weak or uneven heat
Cause: Dirty filters, failing blower motors, or ductwork leaks.
Fix: Filter replacement, blower inspection, and duct sealing restore airflow and improve comfort.
Strange noises from the system
Cause: Loose parts, worn bearings, or clogged burners.
Fix: Tightening hardware, lubricating moving parts, and burner cleaning eliminate noise and prevent further damage.
Frequent cycling or short cycling
Cause: Oversized/undersized equipment, thermostat placement, or airflow restrictions.
Fix: A proper diagnostic will reveal whether a simple repair or system adjustment is needed — Kelvin technicians focus on correcting root causes rather than treating symptoms.
These are the typical issues Kelvin HVAC Services addresses during heating repair calls, and their certified technicians follow a systematic approach to diagnose and resolve each problem efficiently.

DIY tips before the technician arrives
While some repairs should always be left to pros, here are safe steps homeowners can take to possibly restore heat or reduce damage until help arrives:
- Check the thermostat — ensure it’s set to “heat” and the temperature is above room temperature.
- Replace or clean the air filter — a clogged filter can restrict airflow and cause short cycling.
- Check circuit breakers — confirm the furnace’s breaker didn’t trip.
- Clear the area around your furnace and vents — good airflow helps performance.
If these steps don’t help, call a licensed technician — especially for gas-related systems — to avoid safety risks.
