The worst in every way. No communication, overpriced...just awful. Not sure how they've gotten so many good reviews.

The three men who showed up today were Chris, Luis and Dan. They showed up in the timeframe that we were told. They repaired the AC on our roof and replaced the air handling unit. They were courteous and answered all questions. They checked our AC to make sure it was working properly. They cleaned up prior to leaving. read more

Nicholas Mechanical has made the hottest summer ever bearable. Of course our AC went out during the hottest week of the year. I called a few places, but Nathan was the only person that came out the day we called to figure out what was wrong. Turns out that we had two ancient units that pretty much needed to get replaced. Of course, I was nervous that we were going to get a bad deal, so we got several quotes for the replacement. Turns out, Nicholas Mechanical blew them all out of the water with their quote--it seriously wasn't even comparable. Not only that, but their communication was on point, they answered all our questions, gave us options, and helped us make an informed decision. They kept us in the loop the whole time and we couldn't have been happier with our choice to go with them. The installers were helpful, friendly, professional--and most importantly--QUICK!!! I 100% recommend Nicholas Mechanical to anyone that has any sort of AC issues! No only are their prices reasonable, but they do a fantastic job. read more

Professional. Punctual. Courteous. Reasonably-priced. Skilled. Knowledgeable. Qualified Experts. Responsive. Transparent. Honest. Based on personal experience, the above words are just some of the words we associate with Nicholas Mechanical HVAC. I cannot say enough good things about Nathan, Brandon, Alex and their team. We originally had 8 unqualified people sent by AHS, for a period of 2.5 months BEFORE they FINALLY allowed us to choose our own qualified experts. After looking through a handful of companies, I found Nicholas Mechanical HVAC on Amana's website and called them immediately. Nathan and I spoke briefly, and then Alex was patched in to obtain my information. Not only were they very quick to schedule an appointment for us, they made us feel like our issue was a priority. They were transparent and explained the process to us every step of the way, guiding us through the tedious process with AHS (our home warranty company). Nathan was present for every phone call we had with AHS, rooting for us all the way. What took AHS to diagnose for 2.5 months, took Nicholas Mechanical a mere moment to diagnose. What took AHS 2.5 months to replace, took Nicholas Mechanical a turnaround time of 2 day's time, as they needed to order the part and schedule time with us. Today, we will be enjoying our home heater after being without one for 2.5 months. Again, a big THANK YOU to Nicholas Mechanical HVAC, but an even bigger THANK YOU to BRANDON (for performing all the work) AND Nathan (for supporting us & even getting on the calls with us with the home warranty company). If you are looking for fast, immediate and reasonably-priced HVAC repairs (or anything else they offer), please PLEASE PLEASE do NOT hesitate to contact Nicholas Mechanical HVAC. Based on our experience with them this time around, we are definitely looking to use them in the near future for our system maintenance work. Thanks again, Nicholas Mechanical team! read more

We had issues with our A/C for three years, constantly leaking and irregular cooling. Two weeks ago we had a new unit installed by Nicholas Mechanical and it wasn't performing well, as often times anything new needs to be adjusted. We called yesterday to have someone come out. Javier came this morning at 8:00 am. It was so nice to have immediate attention. Unlike maintenance people we encountered in the past, he knew exactly what needed to be done. He was efficient, friendly and professional. Thank you so much Javier and Nicholas Mechanical. read more

We have used Nicholas Mechanical for several projects including replacement of entire HVAC system, duct work, repair service, and additional repairs over the past few years for two properties. They are extremely professional, responsive, and competent. Anytime we have needed HVAC service, they have been quick to respond and have resolved any issues. I would highly recommend Nicholas Mechanical for anyone needing HVAC service. read more

If you don't use Nicholas Mechanical, you are missing out! They are absolutely incredible and I'm pleased to work with this company. Alex and Nathan are so fantastic and have done so much for our Community. They deserve much more than 5 stars! read more

Nathan did a fantastic job. They were timely and very respectful of our house and two small dogs. He was nice enough to text me updates throughout the day on the progress of the installation and to let me know that my dogs were ok. Very much appreciated. I got home from work to a nice cool house and two very exhausted pups. Everything is working great. Thanks for the great job and awesome customer service! read more

Nicholas Mechanical HVAC - Heating & Air Conditioning/HVAC Near Me - Anaheim, California

The worst company. Dont hire these guys they dont know what their doing. The foreman has two years in the trade and thinks he knows what he is doing. They take days installing one unit. They have a guy. His name is Matt better check his duct installs. You pull on the duct and they fall apart. Always begging to lend him money to eat lunch. Simply dont waste your money. read more

From the first call to the final email, this company has been nothing but professional, friendly, and exceptional. Nathan and his team installed a new furnace and a new A.C. system, and I could not be more satisfied as a customer. They were here when they said they would be and they were able to install both very quickly. The estimate I was originally quoted felt fair for the quality I was shown and the professionalism of the team. I would recommend this company without one shadow of a doubt. read more

See all

They were great. I was so happy with how Alex (I think that was her) kept up with calling me and keeping me abreast with what was going on with my property :) She was on top of it!!! read more

I currently work as a Maintenance Coordinator for a property management company in O.C., and I couldn't be happier with Nicholas Mechanicals services. Ever since we started working with them, they have gone above and beyond to take care of our customers! I can say that this is a great company to contact for any HVAC servicing needs. I can say we've only had positive feedback from our tenants and owners regarding their professionalism and cost. Alex is a pleasure to work with and is reliable. She is a true asset to Nicholas Mechanical. read more

These guys replaced all of our ducts a few years ago and most recently I had to call them out for what ended up being some summer maintenance on my AC unit. These guys are on time, friendly, fair priced and always willing to answer any questions. I am happy to put my trust in their expertise when it comes to keeping my family cool during these warm months. Definitely recommend. read more

We have used this company in the past for various reasons from just servicing the ac to proper air flow solutions. My mother has had a bunch of issues recently with her a/c unit and it is so old it really needs replacing. She is in her 70's and this heat we have had recently has left her in a very hot home 82+ degrees. Not healthy for her or her pets and her home protection plan was dragging their feet so I called Nicholas Mechanical HVAC - They were absolutely awesome and brought her a temporary ac unit until they could come install a new unit so she is comfortable! Just wow! Amazing customer service and Nathan is awesome to work with! Such a pleasure on so many levels! Honest and reliable! read more

Thank you for coming out at shut short notice and helping fix our A/C. When I told them my daughter had a bad cough they made sure to be here as soon as possible and were always great at communicating! I highly recommend them and the guys were very polite! read more

Mr. Nichols, 40 years ago was the most honest man with his customers....and his son and grandson followed in his footsteps. If you want an honest company no need to look any more this is it. I love my A/C and my maintenance with this company is the best of the best. read more

Great experience with Nicholas Mechanical HVAC buying and installing a new AC unit. From the estimate process, to the communication, to the team...very professional and well run operation. We got another quote from Costco and felt like the sales guy was just pushing us into the most expensive AC unit he could. Not at all the case with Nicholas. They walked us through what they thought was the best bang for our buck specific to our house and needs, we really appreciated their feedback and felt like they were genuinely trying to help. Their whole team was professional, treated our house with respect, and had great communication. Will be using them for all our HVAC needs and recommending them to all our friends. read more

Very quick response and professional. Fix my AC before the heat comes. Highly recommend Nicholas Mechanical!

Awesome service and professionalism are the core principles of Nicholas Mechanical. Nathan and his team are one of the best I've had the pleasure to work with. His excellence in upgrading my current furnace and installing a new A.C. system exceeded my expectations. The team arrived on time and completed the job ahead of schedule. I highly recommend their services! read more

If you are looking for a great HVAC company, this is the company you want to go with!! I work for a property management company so we have an ongoing work relationship with this company and they have never let us down. Nathan and his team are very knowledgable and professional. Their communication is outstanding; I even refer him to my own friends and family. Thank you, Kelli with White Glove PM read more

Nathan was really a pleasure to work with. They put new ducting in the attic and installed a new furnace and AC as well. One big thing for me as I deal with businesses is Customer Service. That is sometimes a lost art in today's market. Nathan and his team are extremely professional, dedicated, and trustworthy. I could not be happier. Everything was very clear up front and any questions I had were easily answered. Nathan and his team were focused on my project 100% of the time and worked incredibly hard to provide an amazing finished product. Communication was always on point. I am referring this company to any and all that have HVAC needs. read more

Chris did an excellent job installing a smart thermostat for me. I had tried to do it myself and messed up the wiring a little bit. He was able to come in troubleshoot and complete the installation with no real difficulty. He was professional and courteous. I couldn't be happier with the service. read more

Here at APG Properties, we have been working with Nicholas Mechanical for over a year now, and have yet to find a better HVAC Service provider. One of the top issues for any Property Management company is finding a reliable HVAC company.

If you need an amazing HVAC provider, you don't have to keep scrolling through the reviews. Pick up the phone, and make the call now. read more

I highly recommend Nicholas Mechanical. It's been almost a year since they installed my AC unit I purchased from them. They were very thorough with information and quick to responding. I just had them out to maintenance my unit and again very pleased! Chris was the technician out today and he was so nice and informative. I appreciate a well ran business, reliable service, and great customer service. Thanks guys! read more

Ponderosa Property Management has been working with Nathan and his team at Nicholas Mechanical for well over a year and could not be happier. We have used many different companies but none of them come close to the service we receive from Nicholas Mechanical. They always look for a way to make a repair if possible before recommending replacement. Yes, there are "cheaper" companies but Nicholas is the most reliable and easy to work with HVAC company. Don't keep looking for another HVAC company, call Nicholas Mechanical. read more

To begin let it be known this review is based purely on outstanding customer service. I live in South Bend, Indiana and have never met or gotten work done from Nicolas mechanical. What I did do was spend a good part of my morning calling about more than a dozen HVAC companies across the country to get a questioned answered and none would take the time to answer my questions without me scheduling an estimate. One woman told me that there was no one that could answer questions about air conditioning units just because I could schedule an estimate. Nathan at Nicholas Mechanical clear on the other side of the country was literally the only person willing to take the time and help me make an informed decision without trying to force a free estimate down my throat, or treating me like a burden once they found out I wasn't purchasing. I appreciated that. Even assured I could call back in the future just to ask questions knowing that I'm 3000 miles away. I damn near want to fly him out just to hire him. If you ever make it out to Indiana or vice versa I'm buying you a drink or something. read more

This company is great! All of the workers were kind and very respectful of our home. They finished in record time and left the house as they found it, excluding the brand new heating and cooling unit, of course! The office communicated with us each step of the way and things evolved exactly as we were told they were to happen. I still have a little one at home so we were home most of the time that the installation was taking place. They were able to work around us and we felt very comfortable staying. read more

Our air conditioning broke on a 100 degree day. We called Nicholas Mechanical HVAC and they were accommodating and helpful! The technician that came out was beyond kind, respectful and just plain awesome! He quickly diagnosed the problem and was very helpful with explaining what the problem was. Thank you so much to this awesome company!! Highly recommend them for your Heating or air conditioning needs!! 5 stars isn't enough read more

Nathan and Nicholas Mechanical were absolutely superb! Nathan came in and took an extremely stressful situation and kept us at ease all the way through. He has attention to detail, super clean work and fantastic! read more

I have hired Nicholas Mechanical at our home when our air conditioner broke last year. And now just recently hired them for our offices in Yorba linda when the air conditioner went out. They came out immediately in the middle of a heat wave and took care of the problem. And now my husband has hired them for Repair and Maintenance for his Property Management Company. Service, Dedication, Professionalism and most importantly -- they have a Passion for their business which is nice to see in a Business Owner. Highly recommend them --- call them today! You will not be disappointed. read more

These guy are professional, responsive, friendly and got the job done quickly! Nathan was a great guy to work with. I will be recommending them to all my friends. Thanks for ending my 10 week long drier headache read more

There is no one else I would go to for heating or air conditioning needs. They work hard and are always willing to come back ASAP if there are any issues. On time and reliable and very friendly. You won't be disappointed! read more

Excellent first time experience with Nicholas Mechanical. The owner went above and beyond to help solve our problem. He showed excellent knowledge, and problem solving skills. We were very satisfied. Highly recommend. read more

Nathan and his team, Matt and Jason, installed a brand new cooling and heating system, complete with all new ducting in my home in Feb 2016. From start to finish, this team was professional, courteous and punctual. Nate was knowledgeable, attentive to my needs and to the issues we were having in my house. He gave me options and went over each detail patiently and thoroughly. Nate was never once late and always returned my phone calls and text messages promptly. The team was extremely efficient, and sensitive to the fact that I had a toddler in the house and finished the project on time as promised. By market comparison, he was also the most affordable! Over the last 2-3 months, our house has been unbelievably comfortable and the savings on my energy bills has made a HUGE difference :) I don't usually review anyone or anything, and the fact that I am writing this is evidence enough that I am extremely pleased with his service and professionalism. I would definitely use this company again for any heating and cooling needs and I would have given them 10 stars if I could!! I Highly highly recommend him! read more

Nicholas Mechanical installed a complete heating and cooling system in my home last April. They were fast, thorough, clean professional and friendly. The air conditioning unit worked perfectly throughout the summer. Matt came back this week to to do a routine system check and everything was fine. I would recommend Nicholas Mechanical to anyone looking for a thoroughly professional HVAC contractor. read more

I have only great things to say about Nicholas Mechanical. They replaced my mom's HVAC system 3 years ago and she was very happy with them so when my A/C broke down this summer, Nicholas Mechanical was one of companies I called for an estimate. First, they were able to get out the same day I called in the middle of our heat wave. Nathan wrote up 2 separate estimates...1 to repair the AC and 1 to replace the system. There was no pressure. Both estimates were very fair and reasonable and beat the other companies. In the end, we decided to replace our HVAC system since our old one was over 20 years old. While another company told me before they even wrote the estimate that they were scheduling 4 weeks out, Nicholas Mechanical was able to schedule or job within a couple of days. The crew was professional and courteous. They were here when they said they would be here and were continuously keeping me updated. They completed the job timely and cleaned up the job area. They followed up the next day to make sure we were happy and answered all my questions. I wish all contractors gave this type of service. read more

Nathan and George just completed a replacement of our heating and cooling system, including the ducts in the attic. We are totally satisfied with the job they did, as our house now either heats up or cools down much faster than it did before. Both they and their workers are courteous, punctual, and do exactly what they say they will do. After the job was done, Nathan put in several hours of his time to make sure that we got approval from the city. We would definitely recommend NIcholas Mechanical to anyone who needs work done on their HVAC system. read more

This company just installed two new AC /Furnace units and all new ducting in my du-plex down in Newport Beach. I was renovating the entire property and my architect did not have any plans written up for the AC and furnace. That didn't matter to Nate the owner. He guided us through what needed to be done and handled everything in a very businesslike and timely manner from beginning to end. His communication is what puts him at another level. He wont tell you what you want to hear but he will tell you what needs to be done. At the end of the day that's what any customer asks for. I would recommend him to everyone. read more

Our house had a 40 year old AC/heating unit and was in desperate need of an update. From quote to installation was just a few days. Nathan was great about getting us information in a timely manner and he and Matt were both wonderful on the actual install day... prompt, efficient, friendly and amazingly neat for such a messy job. I can't say enough about how easy they made the whole process, simply excellent. read more
