Miranda MorganMarch 22, 2021.VerifiedMy home warranty company set up the appointment with Northvalley mechanical. I didn’t know anything about them. Their tech Brett came out, was on time and personable. Found the issue right away and got our system up and running within about 20 minutes. Super professional and spoke in terms I could understand. I’d definitely recommend these guys!Alan RussellMarch 18, 2021.VerifiedThe technician, Beau Halsey, was excellent: prompt, knowledgeable, and congenial. I will definitely call this company again when I need HVAC work.Thomas PottsMarch 12, 2021.VerifiedJonathan arrived early for the appointment, observed COVID standards while in my home and spent quality time performing the semi-annual maintenance on our HVAC system. He cleaned up everything after he was done, provided pictures of the maintenance and efficiently reported everything that was completed. Very, very professional! I have recommended this company to family, friends and customers, and will continue to do so! Top Notch!!!Joshua NaglerMarch 11, 2021.VerifiedThis company is very responsive. I called for maintenance as a new customer and they put me on the schedule right away. Tyre (sp?) was punctual, professional and thorough. I am very confident that my system is going to perform problem free. I highly recommend this company.Michael StobierskiFebruary 26, 2021.VerifiedGreat Service! HIGHLY RECOMMEND.Karissa NistedFebruary 1, 2021.VerifiedI've used North Valley Mechanical several times now, and I have signed up for routine maintenance under their Comfort Club maintenance program. They have saved me money several times, even coming out at no charge to check my system because I had recently signed up for the maintenance. The technician, Richaard, shows up on time, and is knowledgeable and courteous. The office staff are also responsive and friendly. I highly recommend North Valley Mechanical. 11/15/2020 Previous review Richaard from North Valley came to diagnose my a/c issue the day after I called my home warranty service. He was efficient, knowledgable and very helpful. He even made sure fingerprints were cleaned off before he left. I thought I had a ductwork problem and had previously been told by an AC company that I needed a very expensive repair job. Richaard showed me pictures and meter readings that proved this was not the problem. He saved me from unnecessary work. For A/C service I had a great experience with Richaard and North Valley Mechanical. I will use them again for any A/C needs.Dennis MitchemJanuary 1, 2021.VerifiedExcellent customer service. They shut down my swamp cooler at a very reasonable price. Chris, the tech, was friendly and efficient.Debbie StefaniDecember 14, 2020.VerifiedJonatan responded quickly to my call of no heat. He did what was necessary so I would have heat quickly & repaired the issue causing problem. He was friendly, neat, explained the repairs...couldn't be happier!Aaron KieselburgDecember 4, 2020.VerifiedJonathan was amazing!! So honest and fast, would refer them and specifically him to everyone!!!
