If you are looking for a HVAC Contractor, a Plumbing Contractor, or an Electrical Contractor to provide you with great service, you've come to the right place. We provide heating services, air conditioning services, plumbing services, and electrical services to our customers in Frederick and the surrounding Counties, the Pan Handle of West Virginia, and Northern Virginia, from our offices located in Frederick MD. With 3 generations of experience in providing heating, air conditioning, plumbing, and electrical services, we are dedicated to providing the best possible products and services for you, and your family.
"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."

"🚨 Avoid Len the Plumber – Negligent & Unsafe! 🚨 I hired Len the Plumber to install a brand-new water heater, but it failed after two weeks. They promised quick service but left us without hot water for days. Worse, the first technician concealed a serious fire hazard—the heater’s electrical components had actually caught FIRE and burned! A second technician finally admitted the fire risk, meaning my family could have been in grave danger. This is pure negligence and completely unacceptable. They replaced the heater but only after multiple delays, zero accountability, and putting our safety at risk. 🚫 DO NOT trust this company with your home’s safety! 🚫"

Additional DBA - JCF Inc .
"Jimmy showed up to my home during a time when my thermostat was not working. That issue was fixed. He sold me a services contract and told me when he returned to services the units, he will cover the pipes outdoors. I purchased the contract for twice per year maintenance. I scheduled with him for a specific date. Appointment was confirmed but Jimmy did not show. When I called, he it appears that he forgot my appointment and he rescheduled saying he could not work in the rain. He rescheduled for a few days after and one of his workers showed up (Carlos). The guy showed up looking like he was someone who does not want to work and unprepared. So, I asked him if he has filters and he said know. Jimmy's workman did not bring filter, so I offered him filters I had stored. I asked him if he bought things to cover the pipes at the back, he said no. I called and left a message for Jimmy. Carlos was so rude and unprofessional. I was so scared of him and the way he was behaving. Carlos then said he would NOT do any service. IT WAS A WASTE OF MY TIME. He did return my money. BUT I will not recommend him. Will NOT use him again. As woman I will not hire again. Customer services was poor, reliability and punctuality poor."

Although solar panels are usually at roof level and manufactured to withstand the impact of small airborne debris, they still get damaged and or need maintenance work from time to time. Broken glass from rocks, large hail, or a fall (loose bolts on the mount) are the most common reasons for a repair. Equipment with extensive damage costs less and is more efficient to replace than it is to fix, especially if the equipment is near the end of its lifetime. In this scenario, or if you need roofing work done, you will need to hire a solar panel removal service.
The units themselves are tough and often last beyond their expected lifespan of 25 years. Newer models can last up to 50 years. You'll only need to replace solar panels if they break beyond repair, don’t perform well, or lose efficiency as they approach their end-of-life.
Unless you are leasing your system, you are responsible for maintenance and repairs. However, if certain parts are under warranty, you may have a significant amount of coverage on them. If a panel fails due to an installation error or without explanation, your warranty may cover it. If the unit cracked after an impact, you may be responsible for repairs.
Call your installer and read your warranty before you do any work on your equipment. They will have useful insight into your coverage, service limitations, and options. Many manufacturers offer a 10 to 20-year warranty, while inverters themselves usually have a 10-year warranty. Panels should have a workmanship warranty of at least five years, and your general system should have a warranty of 25 years.
