Problem 1: Thermostat Issues
A malfunctioning thermostat is often the simplest issue to fix. Check if the thermostat is set to “Heat” and the temperature is above room temperature. Replace the batteries if necessary, and ensure the wiring is intact. A faulty thermostat may require professional replacement. Learn about upgrading to a smart thermostat for better control and energy savings.
Problem 2: Furnace Won’t Turn On
If your furnace isn’t turning on, check the power supply. Ensure the circuit breaker isn’t tripped and the power switch near the furnace is on. If the problem persists, there may be an issue with the wiring or control board. Contact Eco Temp HVAC for a professional diagnosis.
Problem 3: Furnace Blowing Cold Air
Cold air from your furnace can indicate a pilot light issue or a problem with the burners. For newer furnaces, inspect the electronic ignition system. A clogged condensate line can also cause this problem. If troubleshooting doesn’t resolve it, our team is here to help.
Problem 4: Insufficient Heating
Poor heating performance is often caused by clogged filters, dirty burners, or a malfunctioning blower motor. Replace the air filter and clean the burners to improve airflow. For deeper issues, schedule a maintenance plan with Eco Temp HVAC.
Problem 5: Clogged Air Filters
A clogged air filter reduces airflow and forces your furnace to work harder, leading to inefficiency and potential damage. Replace filters every 1-3 months, depending on usage and type. Visit our air quality solutions page for advanced filtration options.
Problem 6: Noisy Furnace
Noises like banging, squealing, or rattling often indicate mechanical issues. Loose panels, worn belts, or dirty burners could be the culprits. Tighten screws and clean components, but call a professional if the noise persists.
Problem 7: Short Cycling
Short cycling occurs when the furnace turns on and off too quickly. This can result from a dirty flame sensor, an oversized furnace, or a clogged filter. Clean or replace the flame sensor and check the filter. Our replacement experts can help if your furnace is improperly sized.
Problem 8: Pilot Light Won’t Stay Lit
A faulty thermocouple or a draft near the furnace may extinguish the pilot light. Ensure the thermocouple is clean and properly aligned. If the issue persists, schedule a repair service with Eco Temp HVAC.
Problem 9: Gas Smell
If you smell gas, turn off the furnace and evacuate your home immediately. Contact your gas company and a professional HVAC technician. Gas leaks are serious and require prompt attention.
Problem 10: Old Furnace
Furnaces over 15 years old are less efficient and more prone to breakdowns. Upgrading to a high-efficiency furnace can save you money on energy bills and improve home comfort. Explore our furnace installation services for expert assistance.
