"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."

"The contractor sent to my house was NOT a licensed electrician. I was told a free quote was 39.99, that turned to 59.99 when I got the estimate and it was waaaaaay over priced and then wanted me to pay a fee to get a warranty for their work! I would have expected a warranty on his work should have been given to me! I needed the job done right away, he was pleasant and courteous but never again with this company."

Percolation Tests questions, answered by experts

In the event of suspected or confirmed asbestos contamination on the body, it is imperative to take immediate measures to reduce health risks. To avoid further exposure, carefully remove contaminated clothing and shower thoroughly to remove any asbestos fibers. Seek prompt medical attention, and inform your healthcare professional about your suspected asbestos exposure. Since asbestos-related health issues can take years to surface, regular medical check-ups are advised for anyone with a history of exposure.

Professional testing is advisable to ensure safety regulations are met, and accurate results are obtained using certified methods.

Often found in old insulation, tiles, and roofing materials in pre-1980s buildings.

When learning how to test for asbestos in a popcorn ceiling, you have an option for a DIY job or to hire a professional tester. You can purchase a kit at a hardware store and use personal protective equipment while doing the test. If you don’t want to risk any potential exposure to asbestos, hire a professional asbestos testing company instead.

If you think you’ve touched asbestos, do not put on a mask. This is important because you may take the asbestos fibers on your hands on trap them in the mask. Make your way to a sink and wash your hands thoroughly. Remove any clothes and seal them in a bag, then take a shower. Call your doctor and let them know you’ve been exposed to asbestos, and make sure you see them as soon as possible. The reason you keep the clothes is in case anyone wants to confirm the presence of asbestos.
