"I’ve been a loyal Snell customer for years, but this recent experience was deeply disappointing. After our AC failed in August, Snell diagnosed a leaking evaporator coil. We chose to replace the system through them, and the salesperson took time to evaluate the setup in advance. However, on installation day, the crew arrived without the correct ductwork and had to make adjustments on the fly. Unfortunately, the adjustments were poorly executed: • The Aprilaire humidifier was mounted on sloped ductwork rather than a level surface, contrary to manufacturer specifications. • The hole for the humidifier was cut inaccurately. • The drain line was left kinked in multiple places. Aprilaire support later confirmed the humidifier was not installed correctly and warned this could lead to water backing up into the system — a concern I had raised with the installers before they left. Despite multiple follow-up attempts, I received no meaningful response. I was told my concerns would be escalated, but no one followed through. This was a major investment, and I now feel I need to bring in another HVAC team to correct issues that should have been resolved from the start. I’ve recommended Snell in the past, but I can’t in good faith do so now after this experience."

Additional contact - Judy Shaw. Award winning.

"i have been using Shaw for 10 years and they have installed all my AC. i have told them that they do a good service but overcharging. they replace a dual run start device which should cost between $150 to $250 (hardware cost $30) for $500. it is upsetting to see them taking advantage of old clients."

FAQs for septic system repair projects in Ashburn, VA

Leach field failure can often occur due to a lack of proper maintenance, hydraulic overload, or environmental factors. When too much water enters the septic system—like running multiple large laundry loads back-to-back—it can overwhelm the leach field. Regular professional inspections, ongoing maintenance, and spacing out high-water-use activities help prevent failure.

A septic tank shows repair needs when noticeable symptoms arise around your home. Noticeable signs include strong sewage odors at fixtures, recurring pipe blockages, pooling water or damp patches near the leach field, and areas of unusually bright green or spongy grass. These indicators confirm that deteriorating components or clogs exist. Monitoring such signs and scheduling timely professional inspections prevents further costly damage.

Adhering to a strict, scheduled maintenance plan prevents septic system repairs. An annual inspection and a pump-out every three to five years safeguard your system’s performance. Additionally, only flushing waste and toilet paper, installing drain filters, keeping nonapproved items out of the system, and avoiding excessive water use help maintain your septic system’s health and efficiency.
