"I requested help on Angi on Wednesday and was set up with a Friday appointment. Received a call from Old Skool telling me they could come to my house on Wednesday. Frank came to the house, diagnosed the issue, didn't try to upsell me with things I didn't need. He told me he thought he could have a new AC unit to install on Friday and they are here, on Friday, installing my new AC unit. Everyone at Old Skool is professional and courteous. The price was competitive and not only will I use Old Skool again, but I will recommend them to others. You won't go wrong with Old Skool!"

"These guys were professional and prompt. They answered all my questions and explained everything step by step. No question was dumbed to them. I hired them because my air condition was not blowing cold. They found a leak and we were losing refrigerant. Could have been repaired and refrigerant replaced but my system used an outdated refrigerant and pricey. Strive for Service installed a new Goodman air conditioning compressor and coil. Everything was great and the price was reasonable and I checked. I I I Will definitely hire again!"

They arrived on time, explained everything clearly, and completed the job quickly without cutting corners.

They took the situation seriously, made sure everything was installed correctly, and gave me peace of mind knowing my family and I were safe again. Their workmanship was top-notch, the pricing was fair, and the entire process was smooth and stress-free. I highly recommend Air Bros Mechanical LLC to anyone looking for a trustworthy and reliable HVAC company. Thank you for the outstanding service!"
