Fast. No none sense. Got the job done. Professional Highly recommend. Although I would suggest watching out for the Angi platform. They wanted money in advance for customer guarantee service and quoted me $1,000.00. The work was less than 30 mins and the part was $349. Angi felt like a money-grabbing backdoor fraud. Work with 411 on your own and leave Angi out of your business.

Was very responsive throughout the process. Called us back shortly after sending request for quote via Home Advisor. Came within the two hour window offered the very next day and completed the job without delay. Technician repaired our Central AC during a historically hot stretch of weather and did not oversell us on having to upgrade or replace our unit which was refreshing.

I thought work was to expensive for the time involved repairing the A/C. Time involved less then 45 minutes. It came out to $17.00 per minute. Repair done replace plastic module $359.00, put A/C gas into canister cost $406.00. Other than the cost work was OK.

Sayed called promptly, showed up on time, quickly diagnosed the problem, and completed the repair quickly and efficiently. He worked with me (the home owner) to cycle power when needed, and was understanding about needing to take a few minutes to turn some things off before cycling the power. I would definitely hire him again and would, in fact, call him FIRST. Well done and thank you!

Try to get a quote ahead of time. What was great was speed of arrival and knowledge of problem and ability to fix it quickly. Yet the price was high. Though the work was great! Would I hire them again? Yes I would! Absolutely! Would I get clearer on a price quote up front? Yes I would. Do I reccomend them - Yes!

On one of the hottest days, Mr Opeyany came out and discovered that our air conditioning system was rather complex. He returned the next day and communicated with the vendor representative and after an hour plus, was able to get the system running again. He also let us know what we hadn't been doing in the past re maintenance and what we will need to do in the future. We found him honest and direct in his communication. We would recommend him whole heartedly.

I had my A/C capacitor go out on me during the peak of a heatwave. I got on all the apps to find a hvac company that could come out asap to fix it. 411 heating and AC called me back immediately after reaching out and setup an appointment for the next morning. He showed up on time, was very professional and had great tips for me on how to do some preventative maintenance on my unit to extend its lifespan. I would recommend them and use them again!

The work was completed less than 24 hours after contacting HomeAdvisor! He arrived on the dot of the front end of the estimated arrival time, was very nice, and completed the work at a very good price. I couldn't rate him highly enough! Six stars???

Very efficient, very polite. Job was completed without any mess or inconvenience, and the inspector said it was very well done. The red tape surrounding the permit was horrendous, due to the city's overworked application site, and I would have liked more help with it, but all in all, very accommodating.
