    Very honest and fixed my carrier AC right away. Another company came earlier in the day and said I needed a whole new condenser and that it was gonna be about $6000 or more. I called GRC and they sent Mario a.k.a. super Mario and when I explained everything to him, he changed the capacitor and it started working. Very thankful for luck calling them today.

    Our HVAC system stopped working in the middle of the summer. I tried few other HVAC services, none of them could point out the exact issue or be able to fix it. All of them suggested to replace the system, which would have been a huge cost. Then I got the reference of GRC Mechanicals and this was the best thing that happened. Folks here are very professional, specially Joe & Rob. They are experts at diagnosing complex systems and fixing them. Our system needed a part replacement and Joe went an extra mile to procure it. He showed genuine concern and kept us informed regularly about the shipment status. Their pricing is reasonable and transparent and they give you a fair estimate upfront to the best of their understanding.

    I purchased my home back in 2021 and have worked with countless contractors and companies through various home renovation projects over the years. I can say without a doubt that GRC is on a completely different level when it comes to professionalism, expertise, and organization.<br> We recently had GRC install two 5-ton heat pumps along with an additional mini-split system. Before deciding on GRC, I shopped around and received estimates from several different companies. GRC was the only company that took the time to explain every single detail, requirement, and technical aspect of transitioning our home to a heat pump system. They didn't just throw numbers at us; they truly educated us on what to expect and engineered a tailored solution.<br> On top of their technical expertise, the administrative process was completely effortless. They went above and beyond by researching every single rebate and incentive available for our project and handling the entire application process on our beh
