"Contacted Tully's to have a service rep come out to discuss a problem with a heating/cooling issue in one room in our home. On 7/23/2010 Bow from Tully's came out and checked out our issue and discovered the ducting to this room was too small and explained the problem with me. Bow gave me a price to do the upgrade to the proper size ducting as well as adding an additional floor register to this room to correct the problem and I agreed to the price. Bow also discussed with me, via my request, about their yearly maintenance program on the furnace and A/C equipment. I also agreed to that as the price is very reasonable for what they do and peace of mind. Work was performed on the 28th which was very quickly scheduled (thank you Laura from the office) when Bow came back out and replaced the ducting with the larger size and installed the additional floor register. Bow's work is very professional, clean and neat and there was very little in the way of clean up when he finished. Now that room is nice and cool like the rest of our home and I'm sure it will be nice and warm this Winter and we will have no need for the portable heater that we had to use last year in there. I am happy to be a satisfied Tully's customer! Thank You Tully's!"

Install Boiler FAQs, answered by experts

If you go to turn it counterclockwise and it won’t turn anymore, it’s open. Like most other valves, you should be able to turn a radiator valve counterclockwise (to the left) to open it and clockwise (right) to close it. To close a radiator valve, turn it clockwise until you meet some resistance and can’t turn anymore, but do so carefully to avoid breaking the valve.

If you want to have hot water in your home and part of your plumbing system, you'll need a hot water heater. An alternative may be to heat water as you use it, such as by boiling what you need on the stove. But that's much less efficient and takes considerably longer than hooking up a water heater. Another option is to rely on appliances, such as a dishwasher or washing machine, that heat the water themselves.

All modern boilers are condensing boilers because they’re the most efficient type. Instead of extra heat leaving through the flue, these boilers trap the heat and use it to heat the house. Whether you choose a combi boiler, system boiler, or regular boiler, you can opt to get a condensing system. If you have an old boiler that’s not a condensing boiler, it’s a good idea to get an upgrade.

Generally, an oil furnace is considered safer than a gas furnace for several reasons. While both types of furnaces can produce carbon monoxide, a leak in an oil furnace is easier to detect due to the smell. Oil furnaces also don't connect to a gas pipeline, which reduces the chance of a fuel leak. Most importantly, heating oil is not combustible, whereas natural gas is highly flammable. This means there is a much lower risk of combustion or explosion with an oil furnace. However, an oil furnace can still pose a fire hazard if it tips over.

DIY is not recommended due to safety risks and technical expertise required. Hire licensed professionals.
