I couldn’t be happier with the service I received for my AC repair. From start to finish, the experience was outstanding. The technician arrived on time, was professional, and quickly diagnosed the issue with my system. What impressed me most was how thoroughly everything was explained—no confusing jargon, just clear and honest communication about the problem and the repair options. The work was completed efficiently, and my AC was back up and running the same day. The difference in performance was immediate—cool air flowing strong and evenly throughout the house. On top of that, the technician took the time to check the entire system to make sure everything else was in great shape. It’s rare these days to find a company that delivers both quality work and excellent customer service, but they did exactly that. I highly recommend them to anyone in need of HVAC service. I’ll definitely be calling them again for maintenance and future needs.

⭐⭐⭐⭐⭐ Absolutely Fantastic Service! Mario, the owner, was absolutely fantastic from start to finish. He showed up exactly within the timeframe he promised, listened carefully to the issue I described, and quickly got to work troubleshooting. He pinpointed exactly what needed to be repaired and fixed it efficiently. What impressed me most was how he went above and beyond — checking other parts of the AC system and making a few minor repairs at no extra cost. That level of care and attention to detail is rare these days. I would highly recommend Mario to anyone needing AC repair services. He’s professional, knowledgeable, and clearly cares about doing the job right. If you want quality work and great customer service, Mario is the one to call!

Mario was super knowledgeable. He explained in detail my issues and actually gave me three options to make a decision. Mario fixed my problem in a very timely manner, leaving no mess. I would highly recommend JM Mechanical to friends and family. Thank you again Mario

We had another company come out, we didn’t feel comfortable with their recommendations. JM Mechanical came out, gave us an honest repair with good pricing.

Phew we have air now. On time with a smile. Got right to work, and resolved it all. Pricing was reasonable for a 12 year old unit.

FAQs

  • What should the customer know about your pricing (e.g., discounts, fees)?

    Our pricing is beyond reasonable compared to current market rates. We offer the same repair as the larger companies, at a more affordable price. How? We’ve been in the industry since 2008, allowing us to get the best rates on material. We past the cost down to you the client.
