Humidifiers

Humidifier Repair & Maintenance in Manassas, VA

Have you noticed dry air in your Northern Virginia home during a recent winter heating season? Your heating system raises indoor temperatures and lowers relative humidity. The result is indoor air that feels much drier than other times of year, and that dryness leads to more than discomfort. Dry winter air impacts your family’s health by causing itchy skin, dry nasal passages, dry hair and nails, more frequent colds, increased virus susceptibility and respiratory irritation that worsens conditions like allergies and asthma. Indoor air with low relative humidity may also damages home flooring and woodwork or precious furnishings.

A whole-house humidifier installed in your Northern VA furnace ductwork helps alleviate low relative humidity and restore indoor comfort to your family. These integrated humidifiers require minimal (once annual) maintenance, and they provide deliver humidity levels without the drawbacks of messy, portable units.

When portable humidifiers are not cleaned and maintained regularly—or they are overused—you may create a germ incubator or mold colony. Parrish Services installs leading whole-house humidifiers, along with air filters and air purifiers, to improve indoor air quality. The result is a fine-tuned humidity balance that keeps your family healthy and comfortable during heating season and beyond. Call (571)-650-1016 or connect online to request a humidifier installation estimate.

When choosing a whole-house humidifier, it pays to consult the certified pros at Parrish Services. Achieving comfort depends on correct humidifier sizing that suits your furnace’s heating capacity. Undersized humidifiers add minimal household comfort and oversized devices may deliver too much humidity. We’ll install a humidifier that creates that “just-right” heating and moisture balance.

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!
