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

If a geothermal heat pump is installed correctly, then you shouldn’t have to worry about having a backup heat source such as a furnace or oil boiler. However, there are geothermal systems installed that include a backup in case the heat pump fails due to extreme cold. This is simply a backup heat pump you’ll likely never need and not an alternative heat source.

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.

While it's generally safe to stay in a home with a coolant leak if your home is properly ventilated, it's important to have a professional come out to assess the situation right away. You should evacuate your home if you notice any powerful fumes. Additionally, you should leave your home if you are experiencing headaches or dizziness.

There are three main types of heat pumps. An air-source heat pump system is the most common and has two parts—an indoor air handler unit and an outdoor heat pump unit. A ductless heat pump system functions similarly to an air-source heat pump system but doesn’t need ductwork to distribute the air. A geothermal heat pump system pulls heat from the ground to help heat your home.

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.
