"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."

"I called last week to schedule a time to have someone come in and install a chandelier. Also discussed troubleshooting a switch for a bedroom ceiling fan. They recommended I have a new switch in hand before they came out. The day of I got a courtesy call when they were on their way. Nick arrived right on time. I showed him both issues. He was friendly and professional. He wore an N95 mask for protection the whole time so it felt very safe. He replaced the switch and receiver for the fan and it’s working as expected. He installed the chandelier, and checked the height before finishing up. He cleaned everything up well. Total cost was $275 for both tasks. I highly recommend them. I have used them before and will use them again."

"I had a new electrical line I wanted to run for a display light attached to a grandfather clock in our foyer. I also requested a switch be added to our wall panel by the front door to operate it. The job involved seeking a route for running wire behind the ceiling and drywall from our basement to the first floor of the house. The installation was complicated and obviously required a healthy amount of expertise in all respects. The work was accomplished with a minimal amount of mess (two small holes) and the quad switch panel added by our front door operates flawlessly. During the same visit they also replaced four decorative ceiling light fixtures and repaired a bad electrical outlet to boot. The workers were fast, efficient and friendly (even to my dog). I can't say enough about this company to do this justice. Very satisfied with my decision to give them a call."

Heating Oil questions, answered by experts

Most maintenance checks take 2-5 hours, though extensive repairs may take longer.

An evaporator or swamp cooler is a common alternative for small spaces. These coolers blow moist air into a space to help cool it down. They are more affordable than misters and use much less water. However, coolers will not have the same cooling effect as misters, cannot help plants survive the heat, and only reach a small area.

Geothermal systems provide energy efficiency, lower utility bills, and long-term sustainability with minimal environmental impact.

DIY maintenance like filter cleaning is possible, but professional servicing ensures proper pressure, refrigerant levels, and loop performance.

HVAC systems usually last between 10 and 30 years, with most having a lifespan of around 20 years. Factors that impact a unit’s life expectancy include which brand you choose, how often you use it, and how well you maintain it. To make sure yours lasts as long as possible, make sure to keep it clean and schedule an annual service with an HVAC technician.
