Cost guide # Air Duct Cleaning Companies Cost in Largo, FL: What to Know Cost guide · Updated October 31, 2026 · [Compare 8 local businesses](https://servicescoutlocal.com/florida/largo/air-duct-cleaning-companies/) Short answer Prices for air duct cleaning companies in Largo depend on the size of the job, materials, access and permits. The most reliable figure is a written quote: ask two or three local businesses to price the same work, and compare what each one includes. ## What changes the price - **Size and scope:** the bigger the job and the more trades involved, the higher the price. - **Materials and finishes:** premium materials can change a quote more than labour does. - **Access:** narrow side gates, rooftops or tight lots take longer and need smaller equipment. - **Permits and inspections:** ask whether the permit fee is in the quote and who pulls it. ## Questions to ask each business 1. Is the price fixed, and what exactly does it include? 2. Who pulls the permit, and is the fee included? 3. How long will the work take, and when can you start? 4. What warranty do you give on the work and the materials? 5. Can I see your license number and insurance certificate? ## Local facts: air duct cleaning companies in Largo Public and government data - Cooling degree days per year (Annual cooling degree days (base 65°F), a measure of how much air conditioning a climate needs; NOAA station St. Petersburg International Airport (USW00012873), about 5 miles from the city center point.) 3,701 [NOAA NCEI, U.S. Climate Normals 1991–2020](https://www.ncei.noaa.gov/data/normals-annualseasonal/1991-2020/access/USW00012873.csv) · 1991–2020 normals - Days a year at 90°F or hotter (Average number of days per year with a high of 90°F or more; NOAA station St. Petersburg International Airport (USW00012873), about 5 miles from the city center point.) 94 [NOAA NCEI, U.S. Climate Normals 1991–2020](https://www.ncei.noaa.gov/data/normals-annualseasonal/1991-2020/access/USW00012873.csv) · 1991–2020 normals - Median home value (Median value of owner-occupied homes (ACS table B25077).) $229,100 [U.S. Census Bureau, American Community Survey 5-year estimates](https://data.census.gov/table/ACSDT5Y2024.B25077?g=160XX00US1239425) · 2020–2024 - Homes built before 1990 (35,721 of 46,806 housing units were built in 1989 or earlier (ACS table B25034, year structure built).) 76.3% [U.S. Census Bureau, American Community Survey 5-year estimates](https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US1239425) · 2020–2024 - Households in Largo (Occupied housing units (one household per occupied home), ACS table B25003.) 37,548 [U.S. Census Bureau, American Community Survey 5-year estimates](https://data.census.gov/table/ACSDT5Y2024.B25003?g=160XX00US1239425) · 2020–2024 - Atlantic hurricane season (An average season (1991–2020) has 14 named storms, 7 hurricanes and 3 major hurricanes.)
