K&S sent a technician the same day with no extra charge and the technician stayed until the central heating worked again. He replaced the igniter and the circuit board. It was pricey (approx. $550) but he also could have charged more, considering a family cannot live without heat in MN. The...

Jim was very prompt and reasonably priced. It would have taken me much longer to fix the door myself and I didn't feel like risking a trip to the ER (these springs have very high tension). I think it only took Jim about an hour plus he oiled the garage door so that it sounds much quieter. I was...

Heating Oil questions, answered by experts

You can expect a geothermal system to last for years. According to the Department of Energy, the underground infrastructure for the heat pumps lasts about 25 to 50 years, which includes the pipes buried in the soil. The actual heat pump itself has a life span of around 25 years.

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

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.

Leaks, poor airflow, reduced efficiency, and loop blockages are common problems requiring service.

A geothermal heat pump system will take about 10 years to pay for itself, and it has a life span of anywhere from about 25 to 50 years. Installing a geothermal heat pump will cost about $14,250 upfront, but it can reduce your energy bills by around 65% when compared to a conventional HVAC system.
