    Marwan responded within an hour to our home. He fixed the heater switch etc so my family wouldn’t be cold during the late May and early June gloom days. He’s very professional, knowledgeable and reasonable. I highly recommend him!

    Our AC unit in the attic started leaking through our ceiling on Sunday in the heat of summer in mid August, we contacted Marwan and he was there at 8 am the next day! He was on time, courteous, professional, and thorough. He explained everything very clearly. He needed to order parts to complete the repair and was back by 8 am the next day to install them. AC is now working great. I would use him again in a heartbeat!

    Marwan is wonderful. He shows on time, works hard until job is done. It was 102 degrees that day and he installed hvac system. Very reasonable price also. Highly recommend GMC heating and cooling. Upland ca.

    Mario (Marwan) was kind and very professional! He found the issue with my AC and completely fixed it in about 10 minutes. He knows his work and is great at it! I will be using GMC heating&cooling from now on!
