HEP’s indoor air quality team brings a breath of fresh, conditioned air to Philadelphia homes. Dust, pollen, and pet dander hide in your HVAC pathways all year, forcing the system to work harder and recirculating irritants with every cycle. Our meticulous duct cleaning service removes built-up debris from every register to the main trunk line, restoring free airflow, trimming utility costs, and making each room instantly cleaner and more comfortable.
Unlike one-size-fits-all crews, we pair NADCA-certified technicians with powerful negative-pressure vacuums and live camera inspections, so you see the difference before we seal the vents. While on site, we test for leaks, sanitize with EPA-approved treatments, and fine-tune your heating and air conditioning equipment—all in a single, convenient visit. Ready to clear the air?

FAQs
Why is duct cleaning important for indoor air quality in Philadelphia homes?
Philadelphia’s mix of old housing stock, humid summers, and cold winters can cause dust, pollen, soot, and moisture to build up inside HVAC ductwork. Over time these contaminants circulate through your living spaces, triggering allergies, aggravating asthma, and leaving visible dust on furniture. Professional duct cleaning removes this buildup, helping your heating and cooling system deliver cleaner air, reducing odors, and limiting the spread of mold spores and bacteria common in our region’s damp basements and crawl spaces.
How often should I have my air ducts cleaned or inspected?
The National Air Duct Cleaners Association (NADCA) recommends a full cleaning every 3–5 years for most homes, but Philadelphia properties with pets, smokers, recent renovations, or residents with respiratory conditions may benefit from more frequent service—sometimes every 2–3 years. Even if a full cleaning isn’t needed, we advise an annual visual inspection when we perform your HVAC tune-up so we can spot mold, excessive dust, or pest activity early.
What signs indicate that my HVAC ducts may need professional cleaning?
• Visible dust puffs or debris coming from supply registers when the system turns on. • Persistent musty or smoky odors even after changing filters. • Uneven air flow or rooms that stay dusty despite regular housekeeping. • Increased allergy or asthma symptoms among occupants. • Recent construction, water damage, or rodent/insect infestation in the home. If you notice one or more of these issues, schedule an inspection to determine whether a thorough duct cleaning is warranted.
What does your duct cleaning process involve and how long does it take?
Our NADCA-certified technicians arrive with a high-pressure negative-air machine, HEPA vacuums, and rotary brush tools. 1. We protect flooring and furnishings, then cut access ports in the supply and return trunks. 2. The system is placed under negative pressure so loosened debris is pulled safely into a sealed HEPA filter. 3. Agitation tools scrub each branch line; specialized whips and brushes dislodge dust, pet hair, and microbial growth. 4. We treat contaminated sections with an EPA-approved antimicrobial (optional) and reseal all access points. 5. Registers and grilles are washed, and the blower compartment is vacuumed. A typical Philadelphia rowhome or twin takes 3–4 hours; larger single-family homes may take 5–6 hours.
Will duct cleaning lower my energy bills and improve HVAC performance?
Clean ducts support better airflow, allowing your furnace or air-conditioner to reach set temperatures more quickly and cycle off sooner. The U.S. Department of Energy estimates that 20–30 % of conditioned air can be lost through duct leakage and blockages. By removing obstructions and verifying your ductwork is properly sealed, you may see a 5–15 % reduction in energy usage as well as less wear on motors, blowers, and coils—extending equipment life.
How much does professional duct cleaning cost in the Philadelphia area and what factors affect pricing?
For most rowhomes, townhomes, and small single-family residences, expect to spend $400–$700. Larger homes with multiple HVAC systems can range from $700–$1,200. Price is influenced by: • Total number of supply and return vents • Presence of additional systems (e.g., basement and attic units) • Degree of contamination (mold, soot, construction debris) • Accessibility of ducts (finished basements, tight crawl spaces) • Optional add-ons such as dryer-vent cleaning, antimicrobial fogging, or installing high-efficiency filters.
