Central A/C - Service or Repair
$6,165
They fixed my central unit and said there was a year warranty on the repair. Within a few months the central air unit failed again and they refused to fix it. Made excuses not to. Their own technician said it was their work that needed to be fixed. After spend thousands of dollars I am still without central air.

I hired SuperTech to replace an AC unit with a heat pump. Steven was very helpful and flexible in helping me pick exactly the right package for me (didn’t need emergency heat because we have oil as a backup). I got a nice credit for my old AC unit as well. Installation went smoothly, and they were very responsive when I had an issue with my thermostat shortly after (the new heat pump was causing a phantom error message to show up). Price and service were great - would highly recommend them!

It was great!!! Steven the owner was very helpful in terms of helping me pick out the right A/C unit and thermostat. Dili, who was coordinating things from the office, was very responsive through the process. On the day of the installation, Rick and Martin did a great job and were very friendly. There was a small complication at the end (the issue was related to some idiosyncratic wiring at our house -- our house was built in the 1950's), and Rick and Martin worked tirelessly to fix it and Steven the owner came to help out as well. Overall, it was a wonderful experience at a great price!

They managed to get a tech out to us for a *same-day* inspection. Did a great inspection, were quick during on-site time, and only charged us $70 for the inspection since we were passing repairs on to buyers (was an as-is sale). Stephen was our tech, and was very personable and understanding of (if curious about) some of the quirks of our place. Planning on calling them again for our new house when it's HVAC is due.

They did not show up for the first appt, and did not bother calling. I called them after the timeframe passed and that's when the said they wouldnt be able to make it out. We for the next day. This time they showed up and added Freon to the HVAC, and that was it. Turned out two weeks later we had the same problem because they hadnt detected the leak, so we had to call someone else out and pay more money. Would not recommend this company.

Work was done well, I believe cost was very high, should have been approximately half. I was also charged the deal price through Angie's list but that work was not performed (i.e. standard maintenance) .The estimated cost of the work performed was approximately $300, but I was in a pinch and wanted to get the job done.

Steven was great!! I am a first time homebuyer and we purchased a completely renovated rowhome. He even drew me a diagram to explain how the a/c unit gets cold air into the house. He clearly explained that we would pay a diagnosis fee (WORTH EVERY PENNY) and then we needed to vacuum the line, add free on, and do a pressure test. He basically finished our A/C install that the original contractor should have done. He also mentioned that he does HVAC inspections for I think $60. I wish I would've known this when I got my house inspected because the inspector I used said it was too cold to test the A/C. I will definitely be using Steven & his company again. Side note: I have two 60 pound pit bulls and he was great with dogs!

This guy goes above and beyond the call of duty when it comes to diagnosing the problem and fixing it right. Not only did he give us a great deal, but he kept my family safe from a disastrous situation that was occurring which we were unaware of. He kept coming back until the problem was completely resolved and that included working with the gas company to ensure a gas leak outside of the home was repaired. He actually came out at 10:30pm at night just so he could make sure the gas technician knew the full nature of the problem that he discovered. In the end, Steve installed a great new quality furnace for a fantastic price, and my family is safe in knowing Steve covered all aspects of the job with expert attention to detail. You can trust Steve with your repair. If I ever have a problem, he is my go-to guy for years to come. Thank You Steve!

I gave you all "5s" and here's my review of you and SuperTech: If you are located anywhere in the Baltimore Metro area and have a HVAC problem,do yourself a favor,contact Steven at SuperTech HVAC. His prices and services were superior to the 6 other HVAC repair companies I contacted. He is a perfectionist when it comes to his work. Have used him twice so far and would not consider using another HVAC contractor. Even followed up with me a week after he replaced my entire HVAC system to make sure I was happy and it was working properly! Most doctors doing surgical operations don't even do that anymore!"

The technician showed up as scheduled. He even called us on his way to our home. The diagnosis was quick and accurate. In addition, he patiently explained to us what the cause of the problem was and what needed to be done to fix. The quoted price was very reasonable. After our approval, he fixed the problem and provides warranty for parts and labor.

On a side note, he wore shoe coverings to protect our flooring and did a great job cleaning up afterwards.

Overall, the job was done very professionally, well exceeding our expectations. We could not have been happier. We have recommended this company to our friends and family.
