Heating Oil questions, answered by experts

Yes, technicians check refrigerant levels, loop performance, and system calibration for peak efficiency.

Your HVAC manufacturer will give you instructions on how often you should service your system. Have your unit professionally serviced at least once a year when in doubt. 

Heat pump systems are different because they provide heating and cooling solutions for your home. In this case, you should have it serviced at least twice a year.

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

Yes, including optimizing settings and suggesting upgrades if needed.

For most systems, an annual HVAC system service is more than enough. Some homeowners prefer a twice-a-year visit to ensure the system is ready for the upcoming summer and winter seasons. If you need to call an HVAC pro more often than this, it may be time to check if your system is getting old enough for a replacement.
