"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,"

Solar Panels questions, answered by experts
  • Installing a new electrical meter box

  • Replacing your meter base

  • Replacing your service entrance cable 

The cost to install or upgrade an electrical meter box ranges from $100 to $650, including $50 to $250 for the unit. The meter base passes the power from your electric company to your panel. The cost to replace a meter base is roughly $50 to $250. 

Service entrance cables are electrical cables with multiple wires, bringing power from electrical companies to residential buildings. The cost to replace a service entrance cable ranges roughly from $1,000 to $1,500.

Yes, going solar really saves money. In fact, according to some calculations, the average homeowner who switches from electric to solar power will save almost $2,000 a year on energy costs. While buying solar panels and switching to solar can be costly up front, the savings add up over time. If you can sell back extra energy or take advantage of tax incentives, your savings can be even higher.

Depending on the climate in your area, the best time to install solar panels is either winter or early spring. Summer is a fine time to install panels, too, but it tends to be the busy season, so prices may be higher and companies may have packed schedules. The installation process can take more time than expected between getting permits and finalizing a design, so start as soon as you can.

The average-sized home in the U.S.—around 2,500 square feet—will require between 15 and 34 solar panels to power the whole home. The specific number, however, will have less to do with home size and more to do with how much energy you use each year and the amount of sunlight in your region.

Solar panels should get at least four to six hours of direct sunlight daily. It’s even better if sunlight reaches panels between the peak hours of 10 a.m. and 3 p.m. This is enough to power a home, depending on your solar system’s size and energy needs. Remember that panels will generate some power under cloudy skies or in the shade, and many systems compensate for lower sun exposure by drawing energy from the grid or battery storage.
