Excellent professional service. They were prompt and the pricing was fair. The manager “Elma” helped through the entire process with transparency. Their technicians (Bryan and Paya) were polite, hardworking, and experienced with the HVAC installation. Very happy with Yardz HVAC installation service.

Fantastic service, extremely efficient and very honest service. Someone quoted us five times more for the same service. I highly recommend this company and their staff is fantastic from the first phone. Call to the people who arrived here.

Incredible experience: Friendly office staff worked hard to get necessary parts, schedule repair/replacement quickly Service men are experienced, considerate, efficient, polite, and left the place spotlessly clean!

Yazd was fantastic. They were able to schedule me with a technician within a day and when they came out they diagnosed the problem immediately. Not only that, but they brought the exact part I needed along with them! They were in and out within an hour! Amazing service, very efficient and very easy to contact. I will recommend Yazd Mechanical to everyone I know!

20:53 24 Apr 25

YAZD recently installed an HVAC system in my home after the ancient one that was there when I moved in 3 years ago stopped working. I was impressed with the quality of work done by YAZD. They arrived on time and communicated well prior to and the day of the install. They neatly installed the new system. They cleaned up any mess and left the utility room nice and near when done. They had to come back the following Monday to complete one part of the work, but it was mainly to ensure that the system was working properly which I appreciated. I would recommend them to others.

16:06 23 Apr 25

I found Yadz to be professional, knowledgeable, prompt, and efficient. And I recommend them!

I had a great experience with Yadz Mechanical Service. They were incredibly accommodating and quickly understood the issue I was facing. Even though they recognized that the job had been incorrectly assigned to them, they still went out of their way to help—sending a technician who was not only punctual but also extremely kind and professional.Their customer support was excellent—prompt, responsive, and always willing to answer my questions. From the representatives on the phone to the technician who came out, everyone was knowledgeable, respectful, and genuinely helpful. It’s rare to find a team so dedicated to service.Highly recommended! 5 STARS !!

Prompt and easy to work with. Worked well with them while doing home warranty work. Would use them again for A/C repairs.

23:09 04 Mar 25

Really can’t say enough about how smooth everything went. I was quoted 3x more by one of the larger companies and told the part was back ordered for weeks vs the Yazd team who were far less expensive and were able to resolve same day!

14:46 28 Feb 25

Great job. Explained everything in detail.Finished the work fast and left the work site neat & tidy

04:17 25 Feb 25

Exceptional service and deep expertise—after working with YAZD's team for some time, we knew they were the right choice when it came time to update our AC, HVAC, and water heater. The entire process was handled with the utmost professionalism; they maintained cleanliness and organization from start to finish. If you’re looking for true professionals in the industry who are trustworthy and honest, look no further. Thank you, Elma and the team, for everything! After years of working with you and experiencing your excellent support, we’re confident in referring you as a top-notch company.

YAZD was the contractor sent out via my Home Warranty Co. to fix my AC that was out. He was professional, diagnosed the problem quickly, and what I loved the most was he educated me on what the issue was and what I need to do to maintain the draining system coming from the basement AC (it backed up and flipped the safety switch for the main unit). Customer service is a lost art these days. YAZD gave me hope. I will be using them again.

18:35 08 Jul 24

Iman came over to check our AC system since it wasnt cooling as efficiently as I thought it could. He was polite and professional. We went through AHS warranty service but this wasnt an issue. System was low on freon and Iman charged it up. He setup the supercooling to the exact right temperature and now the system is up and running in good fashion. Thanks Yazd Mechanical and especially Iman the technician.

Sean was dispatched the same day I called and took care of the problem immediately as he has the replacement part on his van. He was professional and nice!

01:35 25 Jun 24

We have used YAZD Mechanical several times over the last few years and every time they've been professional, thorough, explained things well, and transparent. We've been so impressed with their service, that we signed up for their HVAC maintenance plan.

Friendly, prompt and professional. Technician came quickly and fixed the problem very quickly.

16:31 13 Mar 24

Organized and professional! I had my old AC unit replaced and installed a new unit with modifications to my interior unit. YAZD technicians texted me with the appointment reminder, called 15min prior to the appointment and showed up right on time. Completed the installation within the promised timeline. And literally picked up and cleaned the area around the units outdoor and indoor. Great technicians and outstanding service.

The company came out the next day when my heater failed, ordered the part that day, received the part the next day, and installed the part the day after to return the heater to working condition. Quick and professional service.

Very professional, courteous, and accommodating. My heating system broke and we had no heat. Appointment was scheduled next day. I called them and requested same day apt since family member had movement issue. Understanding our situation, Yazd sent a qualified technician the same afternoon. Exceptional courtesy and professionalism. They are as reliable as qualified. Will call them again for any HVAC concerns. Thank you Yazd! Much appreciate your kind consideration.

17:31 06 Dec 23

I had my AC serviced recently by YAZD, the technician Sean responded very quickly and explained everything he did. The out of pocket expenses was more than I expected to pay but the service was outstanding and done in a timely matter.

20:03 11 Jul 23

I have used YAZD for over 5 years for my 2-level HVACs and always feel that their technicians and front office do an amazing job. They are well-trained, honest, never try to upsell, and will try to troubleshoot and repair whenever possible.

My AC went off on a Saturday and after my warranty company gave me their number, I took a chance to call on Sunday and was pleasantly surprised to talk to Sean who was very courteous and professional. He put me on the schedule for the next day and Iman the technician was very prompt, professional and provided a great service.

We had a problem with our AC and they came by so quick at the best price too. They were very professional and time efficient given it is summer time and probably a busy season. I highly recommend this company for fixing AC problems!!

18:50 12 Apr 23

YAZD provides excellent customer service. I’ve worked with them for years and greatly appreciate their speed, knowledge, value and professionalism. Most recently they diagnosed a problem with our AC unit quickly and accurately, and applied a solution that has us back to enjoying a temperature controlled house.

Yazd Mechanical is fantastic. We have now purchased three systems from them. The most recent was a replacement heat pump system install. Kudos to their team. The inside unit was in an INCREDIBLY tight and awkward space -- a VERY difficult space to work in, but they got it done. I find some of the other negative reviews on here difficult to believe as they don't represent my experience at all. Yazd has always provided great customer service, top notch communication, fair prices, and kind and courteous installation teams. We could not be happier.

15:25 13 Feb 23

This company has never let me down. This time it was my heat that went out on one of the coldest weekends this season. YAZD responded diagnosed the issue and called me back that same day to yet me know he was able to get the part and return the next day. He did and my heat is running again. No charge up or trying to get me to buy something I don’t need. These guys are solid and I trust them. You won’t regret giving them your business. I highly recommend their services.
