Air Filters & Purifiers 

Home Air Quality in Manassas, VA

Dust, smoke, pet allergens, pollen and other pollutants compromise your health and detract from your family’s quality of life. Over time, these contaminants build inside your home and expose you to pollutant loads two to five times higher than outdoor air. The Environmental Protection Agency reports that people spend about 90 percent of their time indoors, making indoor pollution a notable health risk.

You can turn your forced-air heating and cooling system into a whole-house air purifier with the addition of advanced filtration and sanitation equipment. Incorporated into the ductwork, supply-air filtration systems clean the air before it is distributed throughout the house. These include:

  • Extended media filters: Boxy filters up to 8” thick and consisting of pleated and compressed paper-like media that filters out particulates
  • Electronic filters: Devices that utilize high voltage current to charge particles which are then subjected to the opposite charge and collected from the air
  • Ultraviolet filters: Effective UV light devices that zap airborne bacteria and viruses

Any heating and cooling maintenance program includes cleaning or changing the air filter frequently. A dirty filter restricts air flow and puts a heavy burden on ventilation equipment. Your air conditioner or forced-air furnace performs more efficiently and lasts longer when filters are cleaned or changed every month.

I had a great experience with Parrish, and the head technician, Danny Shoop (the assistant was also very good). We had a number of plumbing issues that needed repair, and the work was completed to our satisfaction. I was impressed by Danny's professionalism, his work ethic, and the suggestions and recommendations he made. I will definitely use Parrish again.

Brandon did a routine inspection of our HVAC that we knew was reaching its replacement age. He was very professional and honest with his assessment and what needed to be repaired or replaced and why, complete with photos and diagnostics. He made sure I knew all my options and pricing (including cost savings) for the recommended parts and services. Very happy with Brandon’s service and Parrish in general.

My wife, Janice, worked with Alton Wallace to convert our fireplace from gas to electric, and Alton was wonderful! We’d never tackled a project like this before so we had some questions along the way, but Alton was very patient and willing to walk us through step-by-step. He was personable and very knowledgeable. We would definitely recommend Alton to future clients!
