"Tri State was prompt—they had a tech out within hours when our 20-year-old HVAC broke down. The repair estimate was $800–$1,200, and they also sent a salesman, Mike, to discuss replacement. Mike was courteous and knowledgeable, but, when we sat down to review the quote, the sales process turned into a bad car-buying experience. They started at $34,000, then "discounted" to $29,300—$10,000 -$12,000 higher than other quotes for the exact same unit. Even factoring in their warranty, they remained $8,000–$10,000 overpriced. Mike also claimed they were a four-generation family-owned business, but I later found out they’re owned by Sila Services, a Goldman Sachs private equity firm—which feels misleading. To their credit, canceling was easy (though I hadn’t signed a financing agreement or put money down). Bottom line: Get multiple quotes. Their pricing was excessive, and the sales tactics felt manipulative."

We promise accurate quotes that don’t change, and offer an on time service guarantee, with exceptional communication. Our company is committed to being as environmentally friendly as possible by utilizing multiple donation and recycling centers.
"Everything went very smoothly. Sam, the plumber, and is highly professional and knowledgeable. He replaced 3 faucets, 2 sink plugs, two valves, and two supply lines. Sam inspected the p traps, and he added adhesive where it was necessary. Sam also took a look at my two year old hot water heater, and he assessed my water supply to this unit. We discussed performing a complete drain, and check of the components of the heater at a later date. Sam also advised me that a toilet in the basement should be replaced with a more updated commode. We rarely use this toilet, but it's 35 years old. I felt comfortable speaking with Sam. I did not sense he was doing a sales pitch."

"Brad and company did an OUTSTANDING job replacing our A/C units, heat pump, furnace, and hot water heater, and they had the lowest price of the several local companies who provided quotes and provided higher rated equipment! The workers are all friendly, professional, and cared for our home like I do; they left nothing for me to clean or pick up, even offered to run the vacuum in the rooms where they worked! Everything was tested before they left and Brad spent time with my wife and I explaining the functions of the new equipment. They did an absolutely PERFECT job!"

Solar panels are fairly low-maintenance, but they do need occasional attention. A quick wash a couple of times a year and a yearly professional inspection help maintain efficiency. Watch for cracked glass, loose wiring, or hail damage; small fixes cost far less than waiting until output drops. If a panel is badly shattered, replacement—handled by a licensed pro—is often the smarter call.
Most panels last 25 to 50 years, so replacement is rare. Swap them out only when output drops noticeably, the warranty has run its course, or storm damage makes repairs impractical. Track your production data; if efficiency continues to slip even after minor fixes, it’s time to consult a solar installation professional and consider replacing a panel.
Homeowners are accountable for solar panel repairs unless their system is under a leasing agreement. Warranty coverage may reduce repair expenses for specific components. Warranty protection covers repairs when panels fail due to installation errors or unexplained issues. However, if a unit cracks due to an impact, the homeowner is responsible.
Always contact your installer and review your warranty before initiating repairs. Many manufacturers offer warranties ranging from 10 to 20 years. Inverters have a 10-year warranty, panels carry a minimum five-year workmanship warranty, and the overall system is protected for 25 years.
