"We needed our boiler replaced and had multiple companies come and look at the job. We ended up selecting Sila as we read good reviews on the company. Sila surpassed our expectations. The tech who performed the install (Gage) was on time, communicated the entire process to us from start to finish and did a tremendous job. He also made sure to clean up afterwards and was very professional. We would absolutely hire Sila again!"

"We installed a Fujitsu mini-split A/C and heat pump because installing duct work was not an option. The entire process from getting a quote to completing the installation couldn't have been any better. Joe went over the full scope of the project including the ramifications if any additional work was needed. I don't think one could find a better HVAC company than Airco!"

Customers say: Super punctual

"I purchased a new dishwasher and installed it myself. Well, not completely. I ran into some difficulties with the hot water supply line. I called Milltown on a Sunday hoping to get on the list for Monday. Amazingly I got a call on Sunday evening. They came on Monday and not only installed the hot water connection, but also replaced an old leaky hot water shut off. This was in an almost impossible position to access, but he did it in a few minutes. Since he was there I asked him if he could repair a troublesome flush mechanism on one of my toilets. I had other plumbers work on this with limited results. He diagnosed the problem quickly and I'm happy to say it continues to work very well."

"The technician and electrician were both very respectful, knowledgeable, provided all options, were open and honest about why they recommend the service chosen, helped in obtaining the financial services, walked me through the entire process. The technician went above and beyond making sure the. After the water heater install was completed he performed a safety inspection on my heating system, cleaned the debris from the flute into the chimney, made a few tweaks here and there to make sure my system was performed to his satisfaction. I was extremely appreciative of his care, concern and professionalism."

"I would like to recommend Robert from Wotton Heating for your next heating needs. Robert is an incredibly knowledgeable and pleasant tech. I recently moved to my first home and the home heating system was a huge concern to me so i reach out to Robert. As soon as he arrived he was educating me on how the system works and how to maintain it. He answered every question that i had and also provided me with local fuel distributors in my area. He did a great job serving the unit i highly recommend him. Thank you Robert!"

Install Boiler questions, answered by experts

Hydronic and standard electric baseboard heaters differ in how they operate, their cost, and their performance. Standard convection heaters use electric coils to heat the air directly, while hydronic heaters warm a contained liquid like water or oil, which then radiates heat into the room.

In terms of cost and efficiency, hydronic heaters usually have a higher upfront price but are more energy-efficient and cheaper to run over time. This is because the heated liquid retains warmth, allowing the heater to continue providing heat for a while after the thermostat turns it off. In contrast, electric heaters provide heat more quickly but are less efficient.

Ultimately, the better choice depends on your priorities. If you need a room to heat up fast and have a lower initial budget, an electric heater might be suitable. If long-term energy savings are more important and you don't mind a slower heat-up time, a hydronic heater is likely the better option.

Since your boiler keeps you warm and provides hot water to your home, you’re likely to notice issues with heating in your living space right away. The most obvious sign that your boiler is breaking is not getting any heat or hot water. You might also hear some odd sounds coming from your boiler during operation, the flame in your gas boiler is not blue, the pressure is inconsistent, or your boiler is using more energy than it should. If you notice any of these signs, be sure to call a pro right away.

Oil boilers provide reliable heating, efficiency, and long-term cost savings compared to electric options.

When winter rolls around, and you turn the heat on for the first time in a year, it’s normal to sense a light odor. This could smell a little like burning because some dust has gathered in the heating unit over the warm months and will fade away shortly after. However, there are some smells you should watch out for and take caution around: an egg-like sulfur smell or an electrical burn odor would indicate there’s something wrong. Turn it off and call a professional for maintenance as soon as possible. 

The main difference between an outdoor wood furnace versus an outdoor wood boiler is what each appliance is heating. An outdoor wood furnace burns wood to create heat, which warms the air and moves it through the ducts in your home. An outdoor wood boiler uses the heat from burning wood to warm water, which goes through pipes to radiators in the home.
