Power From Space
Power From Space
Lets be honest, Solar Companies don't have a great reputation. They charge too much and sometimes don't properly customize a system to a specific location and don't always deliver what they say they will. Power From Space was started because I have a passion for designing systems that meet each specific customer's individual needs for a price better than the larger companies. As a Sole Proprietor Electrical Engineer that also enjoys hands on work I have installed dozens of high quality and safe systems and I'm proud of each one of them. If you have a sunny roof our ground space near your home and have been thinking of investing in solar I'd be glad to evaluate your location, find out your needs and goals, and give you a proposal if I find the location suitable for solar. I make sure your solar project has a good payback for you even without the federal tax credit and over the life of the system you will double or triple your initial investment!

Horizon Services is the Heating Company Your Friends and Neighbors Call to Keep Warm All Winter Long!
"I wouldn’t be writing this Review if one thing would have happened, TALK TO ME. Don’t place the answering service in the position of telling a Customer that the Supervisor has left for the day at 2.45p on a Thursday. Especially when the Horizon repairman had just fried our whole cooling system, including the thermostat!! What started with a bad fan motor in a new AC system that was only 3.5 years old in a $10,000 system, for which we had waited 4 days for the new motor to be installed. Add to that the fact that the repairman told me he would be at our home at 8.30a and didn’t arrive until 11.30a - after having to use a vacation day to wait at home for them to arrive. Then telling me this will be ‘quick’ all I have to do is switch out the motor by mounting it and plugging in the new one. Hours went by, nothing. He comes in to test the thermostat and it is non-responsive. He tells me to get new batteries, which I did. Then asks me, “these are new?” To which I say, ‘of course’ - you watched me take them out of the box. Then he goes out to his truck for the next 1.5hrs, supposedly speaks with his Supervisor and comes in and tells me that he has fried the system. I reply by saying I will be calling a senior person to speak with them. Called 4 times and never spoke with anyone. Each time I waited on hold for an extended period of time. Each time, I was then told by the answering service that someone would call and never did. Then at 2.45p I am told “everyone has left for the day” and no one would be calling. This was a Thursday, I had been home all day and no one would speak with me. We remain without an AC system, no plan, no calls - - nothing!!! If I could rate them a ZERO, I would,"
