The focus at Polar Bear Jack's Heating and Air Design LLC is for complete customer satisfaction on every job. We believe in offering products and services that we know will give our customers the performance and reliability that we would require for our own homes.

"The guys did not miss a day--they came when they said they were coming. Every day they cleaned up the mess before leaving, including sweeping out the garage (which always has leaves & dirt anyway). All of the guys were friendly and treated our home with respect 100% of the time. They all did their jobs well. There were a couple of specialists and some "worker bees." They answered lots of questions from us as they went along and were not intimidated that we watched what they were doing."

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.

NATE-certified technicians may charge slightly higher service fees compared to non-certified technicians. This is because NATE certification signifies a higher level of expertise and professionalism, often leading to more efficient and effective HVAC repairs and installations. While the upfront cost may be marginally higher, NATE-certified technicians can potentially save you money in the long run by reducing energy consumption, preventing frequent breakdowns, and extending the life span of your HVAC system. When looking for a local HVAC company to hire, it never hurts to ask about NATE certifications.

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.

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.

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