Best Mechanical Equipment in Phoenix AZ

I loved how professional and customer service care this guy was. He knew his job and how to explain things.

Eric Smith did a great job. He diagnosed the problem with my water pressure, fixed it, and showed me what was going on every step of the way. Very nice, personable, and friendly. Highly recommend Goettl and Eric.

This company is amazing. Their work is stellar, they show up on time, and really go out if their way for your needs. It is clear customer service is their main goal. I will never use anyone else.

Wonderful service. Frank went above and beyond. Highly recommend

Reece, Sam, Mario and Jesse were amazing! Everyone was very professional, helpful, communicative, and made the whole experience from quote to installation easy and stress free! I highly recommend this company for any HVAC needs. It’s nice to do business with people of honesty and integrity!

Goliath Mechanical was the best team yet!! Larvell one of their technicians came out to my house and explained everything to me!! I was super happy with this experience. I recommended them to all my family and friends!

Treats their employees like day labors.

Reckless driving.

I can only give a perfect 10 to my experience with Prestige Mechanical LLC. From purchase to installation the results were a smooth transition from beginning to end.

My name is Jose Padron Martinez and I worked for GRAZAK MECHANICAL. This company is the worst company I have ever worked for. The Director of Operations Steve Stahl is unprofessional and made racist comments about Mexicans during employee meetings. I gave my lead Charlie the reasons why I had put my 2 weeks notice and it included Steve Stahl making racist and disrespectful comments about Mexicans. As a result I was let go early for putting my 2 weeks notice and with the reasons behind it being the racial discrimination and the comments Steve Stahl made. This company does not offer equal opportunity. Todos mis Hispanics Por favor no vayan a applicar o a trabajar por esta compania el director de operaciones Steve Stahl es racista contra los Mexicanos y no respeta a los trabajdores. Esta empresa es la peor que eh trabajdo Por. Les repito esta empresa no respeta a los mexicanos y a sus propio trabajadores.

Ive had a lot of issues with this company... but the one I cant get passed is.. they didnt set up the common wire to my Nest tstat.. just so when the battery died they could get another dollar charging me for that fix. I fixed it myself.. and found shady HVAC companies do this to scam costumers.

Our experience with Pro-Tec refrigeration was terrible. We hired them to fix a commercial freezer, that was operating, but wouldn't reach sub-zero temps. After their tech worked on it, the unit would no longer reach temps below the high 30's rendering it completely unusable. I contacted the office the next day (Sat.) and was promised that a technician would be at our place of business first thing Tuesday morning. No one showed up and we have been unable to get a return call. However, Pro Tec did charge our credit card over $1200. We were never given an invoice, any supporting docs or shown any old parts. I called another company and their tech was out the following day and completed the original repair, but also repaired the damage apparently caused by the Pro Tec (which is why it would no longer reach freezing temps after his 'repair'). I understand that people make mistakes, but Pro-Tec's complete lack of customer support and follow through, after the sale, is completely inexcusable in my book.

Great service and great business.

Great group of guys and excellent customer service! Quality and consistency of work was so stellar that that I decided to work for them myself after being a customer for 3 years.

The office staff got technicians out immediately. The techs were very experienced and made sure they fixed the problem. When they needed to refer us to another company to take care of an issue staff followed up with a call to assure we had been taken care of.
