"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."

"We had an absolutely fantastic experience with X&M Heating and Cooling! From start to finish, Richard was beyond responsive, professional, and genuinely a pleasure to work with. You don’t always expect replacing major home systems to feel stress-free, but Richard made the whole process smooth and even enjoyable. They replaced our AC/Furnace (Condenser, Coil Pack, and Heater) as well as our hot water tank—a big job—and the crew knocked it out of the park. Everything was installed with care, attention to detail, and a clear pride in their workmanship. Richard took the time to explain what was happening every step of the way, which gave us total peace of mind. What stood out most, though, was the responsiveness. Whenever I had a question, Richard was quick to answer, patient, and genuinely friendly—it felt like working with a trusted neighbor rather than just a contractor. If you’re looking for a team that does top-notch work - don't look any further."

"Excellent customer service. Excellent finished product. West Shore Home came to install a shower in one bathroom and bathtub/shower in another bathroom. Their customer service is top tier! They took extra caution to ensure they didn’t damage or disrupt my home or other furniture as they carried their equipment in and out of the house. They encouraged me to see the progress as they worked. (Nothing to hide is always a good thing.)

Boiler Repair questions, answered by experts

Leaks, pressure loss, air in the system, burner failures, and thermostat malfunctions are common problems that require professional repair.

Regular maintenance includes annual inspections, filter changes, and checking for leaks or pressure inconsistencies to improve efficiency and longevity.

If your home uses more than one gas appliance, you'll continue to use gas, even outside of the heating season. Your water heater, gas stove and oven, and gas dryer will all use some gas, although typically much less than a furnace. Additionally, those appliances may also have a pilot light that is lit continually, using a small amount even when no one is at home.

Each has its pros and cons, but hydronic heaters typically cost less to use than electric heaters, and they’re slightly more efficient than electric options. On the other hand, a hydronic heater usually takes a bit longer to heat up a room than an electric heater. The “better” choice depends on your needs and budget.

Radiators are a popular home heating choice in older homes, but they are becoming less common in new-construction homes. According to a 2022 report by Elements Visual Capitalist, only around 1.3% of new single-family homes have radiators and similar heating systems, such as baseboard heating.

While they may not be as popular as they once were, radiators today come with more energy-efficient features that can make them practical for modern homeowners.
