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

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

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.

The most obvious downside is the high upfront cost of buying and installing one of these systems. Additionally, sometimes the system can take a longer time to heat than alternatives like a boiler. Also, if something goes wrong with the geothermal pump, repairs are often significantly more expensive than repairing traditional, above-ground heat pumps.

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