Install Boiler questions, answered by experts

It costs homeowners between $5,000 and $12,500 to install a new HVAC system. This number varies, as each home has its own heating and cooling needs. Even a home with the same footage and number of occupants will have different HVAC requirements based on the number of windows, the climate, and how often the occupants use the system. 

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.

The best time to buy home heating oil is in the summer when the demand is lowest, as the prices are usually lower. However, waiting until the summer to buy is often unavoidable unless you install a separate storage tank. If you have the space for a second tank, you can expect to pay between $1,000 and $4,000 for the oil tank replacement or installation, depending on the capacity and location. You could quickly recuperate these costs, though, by stocking up on heating oil in the summer and avoiding deliveries in the winter when prices are highest.

Yes. In many cases, switching from an old furnace to a high-efficiency boiler can help you save money over time. You can also save money by switching from an electric boiler to a gas boiler, which costs much less compared to the energy bills an electric boil can create. Boilers are often (but not always) more efficient than furnaces, too. Then there are discounts, rebates, and incentives that can help you save on the initial costs.

It is almost always more affordable to repair a radiator than it is to replace one. The average radiator repair cost is around $150, and it’s typically about ten times as expensive—around $1,500—to replace a radiator. A repair usually takes under an hour, too, while a replacement can take several hours, making it less of a time commitment to repair one.
