Ductwork Services FAQs

How often should air ducts be cleaned?

Air ducts should be cleaned every 3-5 years under normal conditions. Clean more frequently if: you have pets that shed, family members with allergies or asthma, recent renovations, visible mold growth, or pest infestations. Signs you need duct cleaning include: visible dust from vents, musty odors, increased allergy symptoms, or inconsistent airflow.

How much does emergency HVAC service cost?

Emergency HVAC service typically costs 1.5-3x normal rates. After-hours calls (nights/weekends) usually run $150-$250 for the service call plus parts and labor. Holiday rates can be higher. Many companies charge $100-$200 diagnostic fees for emergency calls, applied to the total repair cost.

How do I relight my furnace pilot light?

For most furnaces: 1) Turn the gas valve to "Off" and wait 5 minutes. 2) Turn it to "Pilot." 3) Press and hold the reset button while bringing a lit match or lighter to the pilot opening. 4) Once lit, continue holding for 30-60 seconds. 5) Release and turn the valve to "On." If it won't stay lit, the thermocouple may need replacement—call a professional.
