"First of all I wanna mention that my experience is similar to many people who have been serviced by j&s as it appears in their Yelp reviews. I had a working furnace that was tripping because of limited airflow, they practically forced me to change the furnace. Which, cost me $4000 and took over 2 weeks. Then the new one had a defective gas valve. Then the furnace kept tripping and stopped working even after changing the valve. I had to reopen the work order for the 3rd time. When they came they found out about the limited airflow from the dirty coil. They said they'll talk with AHS and get back to me, but what they did is they closed the request as completed. I had to call again to reopen the request. When they showed, up they tried to talk me into downgrading my filter. It was too late when I realized that the real issue was a dirty coil and/or duckt work not the furnace. Lastly, they sneakily updated the request to have a non covered item ($200 to change the air filter) this way,"

Heating Oil questions, answered by experts

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.

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

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.

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.
