"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."

Plumbing Heating Companies questions, answered by experts

In the United States, a depth of 36 inches (three feet) for underground water lines is the accepted industry standard. This depth varies from location to location based on local conditions. In areas with colder winters, they may be buried deeper to prevent frozen well water pipes : This is usually at least six inches below the frost level. The International Plumbing Code calls for a minimum of 12 inches below grade.

Ensure there’s a way to flush out excess water from the generator. There will either be a bin you can pull to dump water down the drain or a simple button if your generator is hooked up to a drainage pipe. 

 Ideally, you’ll want to drain after every shower, but there will be a mark on the generator that shows how much water it can hold. Failing to drain the generator can lead to automatic shut-offs or damage.

Choosing the right plumbing materials involves balancing durability, cost, and suitability. Common materials include copper, PEX, and PVC.

An outdoor water valve typically has a round or oval handle that you can turn to control the water flow. It may be located in a protective box or pit near the property line, where the main water line connects to your house.

Although air in your water lines won’t affect the overall quality of your water, it will lead to problems with your well water system if not addressed. Over time, too much air in your water lines can create blockages in your pipes, cause insufficient water flow to your taps and appliances, loosen pipes, and potentially damage important components of your well including your well pump and pressure tank.
