What a crook of a company. I scheduled an appointment for 9:00 AM, yet the technician showed up at…read more8:20 AM. At that exact time, I was getting ready to call and cancel because I had already troubleshooted the issue myself and confirmed my system was working normally, so the service was no longer needed. When I originally called, the only fee mentioned was a $120 diagnostic fee. There was no mention whatsoever of a no-show fee or a travel fee. Now they are trying to force me to pay a $59 travel fee, even though the technician arrived before the scheduled appointment time. To make matters worse, this fee was not explained to me until after they had already shown up. Completely unprofessional and misleading business practices.

After consulting with the Service Manager who was patient and answered all our questions, we felt comfortable in our decision to go forward with this company. In addition to their good reviews and ratings, their price was even better than the competition. The workmen were experienced, efficient, knowledgeable, on time and very neat and the installation was done in one day. I highly recommend this company if you're looking for good value and high quality service.

Honestly, I didn't hire these guys because to even get an appointment you have to open an account…read moreso that they can fill out a ticket and send someone your way. The person who answered the phone wouldn't take my cell phone number so they weren't able to call me to even see if a tech was available. I'm pretty sure that this was just an answering service and not someone in the office. I'm a contractor myself and this is exactly the reason I don't have an answering service. Pro tip for the business owner: When someone calls they want to have answers. I pick up my cell phone so I can talk to my customers, answer questions, and tell them when I'm available ... And not surprisingly, I get a ton of work because I'm the only person who answered my phone. I don't serve this area, but you can find me on Yelp; feel free to call me if you want to chat about how to improve your customer service.

They didn't show, so I called and they said they'll be running a bit late, he said he'll be at my place by noon. Noon came and gone, I tried calling, they don't answer their phones. These guys were no-call, no-show! I can not recommend them to anyone who needs HVAC. These guys are extremely unreliable just like Gen 3 electric and Filippone Electric. Trust me and go with larger companies bc they are professionals for a reason, and time is a valuable commodity ONLY you and I know what your "fake professionals" truly did. You wasted my Time, and time is a valuable commodity. Yes, u are the clowns and goons that are doing this area a poor service. Your actions already noted who you clowns are.

When we needed a new HVAC, we got an estimate from Frederick that was $1000+ over the estimate from another long-time, reputable local company. But out of loyalty to Frederick, we politely asked if they would shave $200 off to come *slightly* closer to this other quote. We actually hate haggling, but had read that you're expected to, for new HVAC. Can't hurt, right? They responded. Had they just said, "No, that's not possible due to XYZ," we would have hired them and paid the full price. But instead the rep explained why it wasn't possible, and then, in a polite but insulted tone, *rescinded their bid*, essentially telling us they would not be doing the job either way. All over a request for $200 off a $7000 job. We were stunned. Needless to say, we haven't called them for anything since, and we're the kind of easy-going, non-complaining customers contractors usually like to have. We got our HVAC at the other place and it's running fine, a few years later. Owner, if you're reading this: I get that you're doing well enough that you don't need to accept anyone's attempt to haggle, and can charge a lot more than the competition. Good for you. I'm purposefully not giving you a 1 star because I don't believe in trying to hurt someone's business. But talk to your guys about not reacting in a personal way to long-time customers. The reaction we got was really uncalled for. Maybe the guy was having a bad day, but you have to leave that behind when you're interacting with a customer, especially an established one. He could have just said "No, we can't do that, but let me know if you want to proceed with us." We would have.
