It was done as promised.I had checked out the different brands and this band has a good rating. What sold them is it was the best price for heating with air. We were replacing a propane heater and the air was basicly a bonus.

Heating Oil questions, answered by experts

You need to service an HVAC system about twice per year, with a service including an inspection and basic maintenance. It’s best to schedule maintenance in the spring (after the furnace has been running and before the AC kicks on) and in the fall (after the AC worked hard all summer and before winter’s first chill arrives).

Regular HVAC services will keep the system working as efficiently as possible, saving you money on utilities and larger repairs. HVAC maintenance costs around $250 per visit, while bigger repairs from forgotten upkeep could cost thousands.

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

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

Service costs range from $200 to $1,500, depending on maintenance needs, system age, and labor.

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