"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."

"They charged $98 to come give me an estimate for swapping our a shower valve cartridge, which was fine, but the pricing they provided was completely unreasonable, $1,000. They were unwilling to provide any detail for the price. I ended up buy the part myself for $30 and replaced it in 30 minutes."

Boiler Repair questions, answered by experts

Not every type of baseboard heater needs to be bled. Hydronic baseboard heaters need to have air removed at least occasionally, but electric or gas versions that don’t use water at all don’t need to be bled. There are no pipes or valves on these models to worry about, nor any central boiler. Instead, they use heating elements or other methods to supply direct heat to a room.

Clean regularly, check for leaks, and schedule annual inspections for safety and efficiency.

The best way to save money on home heating oil is to get large deliveries in the summer months when the prices are lowest. However, this method will only work if you have a separate storage tank or an unusually large primary tank. You can sometimes save money by opting into a delivery contract, as some companies offer set prices that they believe will sit at the average cost over the contract term. If the price of oil rises, you could enjoy some savings, but keep in mind that you might also pay a bit more if the price decreases.

There are many signs and symptoms to look out for that can indicate that your HVAC system needs repair, including the following:

  • Your indoor air is uncomfortably hot or cold.

  • Your energy bills suddenly increase without explanation.

  • Your AC is blowing warm air or not blowing air at all.

  • You notice leaks around your HVAC equipment.

  • Your equipment makes unusual noises during operation.

  • You notice strange odors coming from your equipment.

  • You notice that the humidity in your home is higher than normal.

  • The thermostat no longer seems to match the actual temperature.

Blockages can occur for various reasons, primarily linked to the accumulation of debris or substances within the heating system. Common causes include the buildup of sediment, rust, or mineral deposits inside the boiler or its pipes, hindering water flow and heat transfer. Additionally, air pockets or trapped gasses can impede circulation. In central heating systems, sludge or corrosion within radiators can obstruct the flow of hot water. External factors like frozen pipes in winter can also lead to blockages. Regular maintenance will help prevent blockages and ensure efficient boiler operation.
