Heating Oil questions, answered by experts

Costs depend on system age, type, labor, and whether part replacements are necessary.

It’s a better use of energy (and your money) NOT to run an ERV system all the time. Most experts recommend that you cycle your ERV system on and off throughout the year. However, the recommended advice could change based on your climate, the number of people in your home, the size and style of your home, and your heating and cooling system. Contact a local pro for more specific advice.

HVAC systems usually last between 10 and 30 years, with most having a lifespan of around 20 years. Factors that impact a unit’s life expectancy include which brand you choose, how often you use it, and how well you maintain it. To make sure yours lasts as long as possible, make sure to keep it clean and schedule an annual service with an HVAC technician.

Yes, many providers offer organic or eco-friendly treatments. Confirm availability with your contractor.

If a geothermal heat pump is installed correctly, then you shouldn’t have to worry about having a backup heat source such as a furnace or oil boiler. However, there are geothermal systems installed that include a backup in case the heat pump fails due to extreme cold. This is simply a backup heat pump you’ll likely never need and not an alternative heat source.
