Air Quality and Filtration System Cost: HVAC Contractor Guide
HVAC contractors should charge $500-$1,500 for whole-house air filtration system installations, $400-$1,200 for UV germicidal light systems, and $1,500-$3,500 for advanced air purification systems like iWave or REME HALO. Media filter cabinet upgrades run $200-$450 installed. Indoor air quality is a high-margin add-on category with 50-70% profit margins on most products.
Indoor air quality (IAQ) has become one of the fastest-growing revenue categories in residential HVAC, driven by health awareness, allergy concerns, and the post-pandemic focus on clean indoor air. For HVAC contractors, IAQ products offer exceptional margins — many are quick installations with high perceived value. This guide covers pricing for every IAQ product category and strategies for making air quality a core part of your business.
Media Filter Cabinet Upgrades
The simplest and most common IAQ upgrade is replacing the standard 1-inch filter slot with a 4-5 inch media filter cabinet. These cabinets accept high-efficiency pleated filters (MERV 11-16) that capture far more particulates than standard 1-inch filters. Wholesale cost for a media filter cabinet (Honeywell F100, Carrier FILXXFNC, Aprilaire 2410) runs $80-$150. Replacement filters cost $25-$50 each and should be changed every 6-12 months. Installation takes 30-60 minutes: cut into the return air duct, install the cabinet, and seal all connections. Total to homeowner: $200-$450 installed. The margin on media filter upgrades is excellent — 60-70% profit on a 30-minute job. Make this a standard add-on in every system replacement proposal and offer it as an upsell during maintenance visits. "Your 1-inch filter only catches large dust particles. A 4-inch media filter captures allergens, pet dander, and mold spores that your current filter misses."
UV Germicidal Light System Pricing
UV-C germicidal lights installed in the ductwork or near the evaporator coil kill mold, bacteria, and viruses that pass through the HVAC system. There are two main types: coil-sterilization UV lights that mount near the evaporator coil to prevent mold growth on the coil surface (run 24/7), and air-sterilization UV lights that mount in the return duct to kill airborne pathogens as they pass through. Wholesale costs run $100-$400 depending on the model and UV intensity. Popular brands include Fresh-Aire UV, Honeywell UV, and RGF REME. Installation takes 30-90 minutes: mount the UV lamp, wire it to a power source (typically the furnace transformer or a dedicated outlet), and verify operation. Total to homeowner: $400-$1,200 depending on the unit and installation complexity. UV bulbs need annual replacement ($50-$100 wholesale), which creates recurring revenue — add bulb replacement to your maintenance plan as an included or discounted service. UV lights are an easy sell for homeowners with allergies, asthma, or visible mold on their evaporator coil.
Whole-House Air Purification System Pricing
Advanced whole-house air purifiers go beyond filtration and UV by actively treating the air throughout the home. The most popular products are bi-polar ionization systems (iWave, GPS Needlepoint) and photo-catalytic oxidation systems (REME HALO, Fresh-Aire APCO). Wholesale costs for these systems run $400-$1,200. Installation takes 45-90 minutes: mount the unit in the supply plenum or return duct, wire to a 24V or 120V power source, and verify operation. Total to homeowner: $1,500-$3,500 depending on the product and installation. These systems have the highest margins in the IAQ category — 55-70% profit is typical. The selling point is whole-house coverage: "Unlike portable air purifiers that only clean one room, this system treats every room in your home through your existing ductwork." Be prepared to address customer questions about ozone generation — modern ionization and PCO systems produce negligible ozone, but some homeowners have concerns. Carry manufacturer documentation on ozone compliance testing.
Electronic Air Cleaner Pricing
Electronic air cleaners (EACs) use electrostatic precipitation to capture particles — they charge airborne particles and then collect them on oppositely charged plates. Popular models include the Honeywell F300, Carrier GAPAA, and Trane CleanEffects. Wholesale costs run $300-$700. Installation is straightforward — they mount in the same location as a media filter cabinet but require a 120V electrical connection. Installation takes 1-2 hours. Total to homeowner: $800-$1,800. The advantage of EACs over media filters is that the collector plates are washable — homeowners save on replacement filter costs over time. However, EACs require regular cleaning (every 1-3 months) to maintain effectiveness, and some models produce trace amounts of ozone. EAC popularity has declined somewhat in favor of ionization systems, but they remain a viable mid-range IAQ option. If offering EACs, make sure to educate the homeowner on the cleaning requirement — unwashed plates reduce effectiveness to near zero.
Ventilation and Energy Recovery Systems
Modern homes are increasingly airtight, which saves energy but can trap pollutants, CO2, and excess moisture indoors. Energy recovery ventilators (ERVs) and heat recovery ventilators (HRVs) exchange stale indoor air with fresh outdoor air while recovering 70-85% of the heating or cooling energy from the exhaust air. Wholesale costs for residential ERV/HRV units run $500-$1,500 depending on airflow capacity (100-300 CFM). Installation is more complex than other IAQ products: you need to connect the unit to the existing duct system, install fresh air intake and exhaust ducts to the exterior, wire the controls, and balance the airflow. Installation takes 4-8 hours. Total to homeowner: $2,000-$5,000. ERVs and HRVs are ideal for homes with humidity issues, new construction with tight building envelopes, and homeowners who report persistent stuffiness or condensation on windows. These are premium installations that showcase your expertise and generate excellent margins.
Building IAQ Into Your Sales Process
The most successful HVAC contractors make IAQ a standard part of every estimate and service call. Include an IAQ section in every system replacement proposal with at least two options: a media filter upgrade ($200-$450) and a whole-house air purifier ($1,500-$3,500). Frame these as optional add-ons, not upsells. During maintenance visits, use a simple IAQ assessment: check filter condition, inspect the coil for mold, note any musty odors, and ask about allergies or respiratory issues. If any issues are present, recommend the appropriate solution. Stock IAQ products on your trucks — a media filter cabinet, a UV light, and a bi-polar ionizer cover 90% of residential IAQ needs. Having products available for same-day installation dramatically increases conversion rates. Track your IAQ attachment rate (percentage of installations and service calls that include an IAQ product) — top HVAC companies achieve 30-50% attachment rates, generating $200-$1,000 in additional revenue per job.
