I had such a great experience with SuperTech HVAC Services in Timonium! Alfonso and Jason were amazing—so friendly, patient, and knowledgeable. They took the time to explain how my furnace works and made sure everything was running perfectly before they left. It’s so nice to have technicians who genuinely care and don’t rush through the job. I really appreciate their honesty and professionalism. I’ll definitely call SuperTech again and recommend them to anyone who needs HVAC service.

I have been a satisfied customer of Super Tech Services for approximately five months. I always get good service from them. The office personal are always friendly and helpful. Even if it is something as simple as a reading on the thermostat that I don't understand. A great BIG shout-out to Ebony for always being so friendly and helpful.

We’ve had a good experience with SuperTech HVAC. Alternatively, we’ve had some crap experiences with other HVAC services. Thankfully, SuperTech staff were excellent. 1) Communications around pricing for a full replacement of our upstairs system were clear. 2) Administrative Staff were reliably prompt, friendly and helpful. 3) A follow-up walk-through with the Supervisory Staff to review the operational considerations of the installation went well. 4) And finally, the installation of our maximum efficiency heat pump went really smoothly. I’m relieved to have established a maintenance and support relationship with SuperTech. I’m very happy to provide our family’s recommendation.

Alfonso is great to work with. He obviously knows his stuff and he is personable and friendly besides. Today he "fixed" our furnace just by walking in! Yesterday morning it was making all kinds of screeching noises but was perfectly quiet when Alfonso came today and I turned it back on.
