Heating Oil questions, answered by experts

DIY maintenance like filter cleaning is possible, but professional servicing ensures proper pressure, refrigerant levels, and loop performance.

Regular inspections, loop flushing, and checking heat exchangers help extend system lifespan.

Most maintenance checks take 2-5 hours, though extensive repairs may take longer.

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

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.
