Very reliable

Raul was very personable and professional. He called in advance to confirm and came back as promised the next day to fix our dryer after his initial diagnosis.

Price was the highest of all contractors I asked for a quote from. Not at all competitive with other companies for the same product and service. Definitely recommend getting multiple quotes from different contractors before selecting a company. Edit: to answer below, the reason for one star is because the job was not to repair something. It was to replace. All the other contractors were quoting for the same replacement. The actual price will not be lower than your quote will it? Price gouging is not a good business model

Our washing machine was rattling and making a lot of noice so we did a google search for repair service. We found out during this search that Certified Mechanical has the designation of Google Guarantee which means (Businesses with the 'Google guaranteed' badge are screened, and are guaranteed to get the job done right or your money back with a lifetime cap of $2,000. ) Anthony the owner of the establishment sent a repair technician and the charged us for $99 to see visit out place and diagnose the problem. The repair was going to be costly so we decided to purchase a new washer and dryer. We called Anthony to provide us with quotes of 3 brands and see which one was in stock and we decided to proceed with the brand that was available and in stock. (This was not our 1st choice but we had did not want to wait 2 weeks plus) We understand the supply chain issues and low inventory and wanted the delivery and install to be done within 3 days. The only thing that I would say is that Certified Mechanical had to outsource the installation of the machines to another trade but we are happy with Certified Mechanical that the trades assigned to install the machines did a good job. Thank you Google for screening the vendors as it sure helps in make a decision and thank you for the $2000 guarantee.

Ronnie's definitely a magician, in the best way possible. I work in the property management field and had an issue with a high end commercial dishwasher. Ronnie was on time, professional and informative. He was able to not only fix our machine but leave it functioning better than it was pre breakdown. Keep guys like this around, your sanity and your wallet will thank you.

Thank you for your excellent service as always. Ronnie is so knowledgeable and good to work with. Always a pleasure!

Absolutely happy with the service that was provided. It was professional, quick, and honest. Anthony was able to come and access the problem with my fridge and was able to fix it within 15 min. Whoever requires any kind of repair, Anthony and his company is the company you need to contact. Unfortunately I previously had hired another company and they simply scammed me and didn't fix anything. Disappointed that I didn't find Anthony sooner. I would give more than 5 stars if I could.
