"Worst service I’ve ever have experienced. They wanted to sell me the product, never told me that there was an early termination fee and another penalty for an initial offer they gave me. Had double charges every month, once for the oil they provided (which they never told me they were going to provide before coming. They just came without my knowledge and then I find a high amount bill) and another for an “automatic payment” for 500 that they never could explain. The didn’t even fix this issue and it kept happening every month even after I cancelled the service. Then having to call them is a hastié for the refund of the 500. Stay away of this company"

"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,"

This time again they were charging us for the defective part and exorbitantly for the service call under the pretext that we did not sign a maintenance contract with them.

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.

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

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.

Yes, geothermal heat pumps are worth the money. You can save about 70% on heating costs in the winter and around 50% on cooling costs in the summer with a geothermal heat pump compared to a traditional HVAC system. Over time, your savings on monthly utilities will pay for the cost of the geothermal heat pump installation. If you have an incredibly small yard, however, you may not have enough space for this type of system.

Most HVAC companies charge a flat service call fee of between $75 and $150, which includes traveling to your home and inspecting your system to find the underlying problem. Keep in mind that these prices only include diagnostics and the actual repairs will usually be billed separately. If you’re calling for routine service, the service call will be included in your inspection and tune-up, with the total sitting around $150. Your prices could be a little higher if you have a very large home with multiple condensers and air handlers, as inspections and servicing take longer.
