"This was the worst experience i have ever had with a company. They came and damaged my house and kept us without AC for days. They admitted to the extensive damage and went weeks before attempting to repair it. The services were never fully completed and they were paid over 90% of the job. I disputed the last 10% and provided overwhelming evidence of their negligence. And after a year their last ditch effort was to send collections letters. Don't walk, RUN from this company. I will provide pics and my my experience to anyone who is planning on using this company. Used to be family owned and was amazing. Second they sold it went downhill fast."

"They installed a minisplit cooling system, with 3 exchanges June 2021. Since then it is not operating the way it should. In my bedroom with the door closed at night on cool at 70 degrees the humidity goes up to 80%. I wake up uncomfortable, change it from cool to dry mode. The humidity will go down into the 50% range but the temperature drops down to 62 or less! So in cool or dry mode I can't get a good nights sleep! They come and look at it and tell me everything is fine. I'm going to buy a window air conditioner tomorrow which seems insane because i spent $10,000 on this minisplit AC system!"

Solar Panels questions, answered by experts

Removing solar panels can be straightforward, but it’s not necessarily a simple process. Your contractor needs to prevent damage—not only to your panels but also to your roof and electrical system. Many systems are wired into the main electrical grid, and you’ll need to hire a licensed electrician to disconnect it.

As long as your solar panels are properly installed without damage to your roof, they will not shorten the roof’s life span. Solar panels can act as a cover or barrier to your roof and help block external elements, such as debris, heat, and UV rays. Reduced exposure to the weather can extend your roof’s life.

Yes, you can connect an inverter directly to your solar panels without solar battery storage if your home is connected to the power grid. However, most pros don’t recommend a direct connection because solar panels don’t put out steady voltage. It’s always best to install a charge controller between your solar panel and your inverter to regulate the flow of energy and ensure a stable power supply.

Solar well pumps range from needing 200 watts of power to as much as 12,000 watts for heavy-duty pumps. Since the most common and cost-friendly solar panels are 100-watt panels, you’ll need between two and 12 panels. The average is between two and eight panels for standard pumps. Based on the average cost of solar panels ($1 to $1.50 per watt), you’d pay between $200 and $1,800 for your well pump solar panels—not including installation.

You can start narrowing your search for a reputable solar company by finding local, regional, and national companies that service your area and maintain positive reviews online. You should also check the Better Business Bureau’s (BBB) website to see if the company has complaints filed against them. Next, contact the remaining candidates and ask about installation timelines, warranty coverage, and financing options. Choose a company that offers a labor warranty that lasts at least 10 years and prioritizes cash purchases and solar loans.
