The estimate I received included a full furnace replacement I never requested, totaling over $25,000. When I asked for a revised AC-only quote, Kevin declined via text message citing workload. No explanation was offered for why a simple quote revision could not be provided. Disappointing experience from a company with such a "strong" local reputation.

Mark is a one-man operator who consistently provides top-notch customer service. I've used his services on many occasions, and he is always responsive, on time, and excellent with follow-up, consistently delivering a truly great customer experience. If, for any reason, a job is beyond his scope, he is completely upfront about it. Even if a repair takes more than a day, Mark will keep you updated on his availability and any parts that are on order. I would not hesitate to call or contact Mark for any of your HVAC needs. He absolutely deserves a full 5 stars.

Our AC stopped working last week. Contacted Rocky HVAC. The rep came out the next day. He was very…read morehonest and helpful to explain our options. We got a great deal on a whole new HVAC system. It came with a 10 year warranty on labor and parts,most others only offered 2 years on parts and 1 year on labor. We got a money off from BGE and next years taxes too to really help cover the costs. The installers showed up early. They were very professional and helpful. They did a great job with the installation. They went above and beyond,they fixed things that we didn't even have to ask them to fix. Rocky HVAC made the whole experience better than I thought it would be.

The HVAC installation itself was done well, and I was satisfied with the work performed by the…read moreinstallation technician. My concern is with how the required county inspection was handled by the owner. I was charged an additional $500 for the inspection, even though the county's actual permit and inspection fees are less than half that amount. The explanation was that the additional charge covered scheduling the inspection and having someone present, which I was willing to accept. However, the person they sent arrived late, was not the installer, and did not appear familiar with the installation. When the inspector asked questions, he was unable to provide useful answers. Considering the amount charged, I expected someone knowledgeable about the job to attend and properly represent the company. I raised these concerns directly with the owner, but instead of acknowledging the poor handling of the inspection or taking responsibility for the situation, he avoided addressing the issue. Because the inspection charge and arrangements came directly from the owner, the experience left me feeling that the additional cost was not handled transparently or professionally. These are the types of business practices that prevent me from becoming a repeat customer, despite the installation itself being completed well. I recommend that anyone hiring this company confirm in writing whether permits and inspections are included in the original quote, the exact amount of any additional charges, and who will attend the inspection.

Compressor was in bad shape (nothing I did). Unit under a 5-yr warranty. Vincent said that it would NOT be honored by the manufacture (Goodman) because it was "damaged." What! In the same breath, he offered to "sell" me one of his units for $2,500. I spent $5,600 already. Why offer this? Then, he gave me a week to answer. Through another tech, the compressor WAS found to be under warranty, and I was able to get that put in by someone else. He scammed me and thought I was a fool to buy a unit from him when I had already paid for a unit that was under warranty. Why tell me mine was not under warranty when it was. That's unprofessional, disrespectful, rude, unthoughtful, inconsiderate and appalling to me! This is not how business is done. He tried to act like he was helping me, but this was the worse business transaction any company could make. I would never recommend him to anyone. I'm sure someone has been through this same type of experience with him too!! TELL IT!!!!! He doesn't deserve to be in business!! This smells SCAM! If I could rate no stars, I would. Also, he did not do his due diligence as far as my duct work being compatible for the units he put in as well as the thermostat. An awful experience!!!!!
