Extremely friendly and professional. Reasonably priced and knowledgeable. Will use again and would recommend.
5 Diamond reps and owner have serviced our AC downtown in a highrise for the last 3 years. They are always honest, polite, and respectful.
It took us a little while to get connected playing phone tag but I am glad it worked out as this company is on it. I am huge on customer service and they are on top of it. Brent was amazing servicing our A/C as well as explaining a few things I had questions on. I would definitely recommend them to anyone looking to have work done!
Super helpful and really nice. I actually got to talk to real live person on the phone and I got an appt the very next day. Nick was friendly and informative and fixed the issue in under an hour. I've hired a lot of HVAC people so even by comparison they were great. Nick was late but was very apologetic and didn't charge us for some replacement fuses that we needed.
I would definitely call them again!
A great 5 star company. They are my go-to for San Diego AC install and repair. Most recently they serviced my ductless mini split system that was having problems.
These guys are awesome. I had an appointment scheduled out a week in advance but an emergency left me in a tight spot. Carlos was wonderful over the phone and worked extremely hard to get me a same day appointment (!!!!). Within an hour, I had Brent and Shelby at my house. They were able to find the problem and correct it within an hour. They even took the extra step to show me what was wrong and took precaution to protect my flooring. They then helped me reinstall the nest which included anchors and drilling which was a HUGE help. I highly recommend them--very quick, very honest, thorough and straight forward company. Thanks again!!
Great Communication and Service! From start to finish, 5 Diamond kept me informed every step of the way. Justin was courteous and kept me informed of all the repairs. It's nice to have a contractor that keeps you informed and does what they promise to do. Highly recommended!
I'm not one who used to write reviews, but Carlos and his team go above and beyond for their customers. Not only are they prompt, clean and honest (big plus), but they are efficient and cheerful. They answer all my questions, and are responsive about pre/post communications. Very professional, and Great people!
Great company and excellent service. Scheduling was easy. They are very friendly and helpful both on phone and in person. Ready to go "extra mile". Fixing my A/C was fast. They found a wall unit that was suitable for my parents to use. They were very considerate and thoughtful. Thank you!
I had an excellent experience w 5 Diamond.. my AC has now been serviced and is running efficiently..and I only contacted them last week! That's pretty unheard of in this type of industry. I also appreciated the time Justin spent showing me the functions of the AC Unit and what to keep an eye on.. he even made sure the water overflow sensor was actually working.. oh and he was on time and very pleasant too.. thank u!!
The technician arrived exactly on time, surveyed my HVAC system and gave it a clean bill of health. I would definitely call them again for service.
These guys replaced a wall furnace for me. This was a very last minute appointment just a couple of days before Christmas. They were fast, professional and had the new furnace installed in no time at all. Competitive pricing and really great customer service! I can't sing their praises loud enough! A++ service all the way :)
Have used them a couple of times for different services, always excellent customer service from beginning to end. Definitely recommend them.
Had a great overall experience! The technician Brent was on time, thorough and did a great job explaining everything. Will definitely use them again!
Scheduled a maintenance inspection on the mini-split units in my home. Carlos was very professional when scheduling the appointment. The technician arrived on time and did a thorough job of cleaning and getting the units ready for the winter months. He tested the units and everything checked out great. The technician was also very professional and knowledgeable. That's all you can ask for -- good people and good service!
Excellent service. They made time to come out the next day after I requested a quote. I wish I could remember the name of the tech who came by but he was very friendly and efficient t. He explained exactly what he was doing and why and identified the problem immediately (a burnt out fuse). I would absolutely recommend this company.
I was very happy with the customer service, prompt service, work, price and overall professionalism. When another company wanted to take advantage of me and my lack of knowledge about A/c and heating, 5 Diamond came through and fixed my a/c. The repair guy was as nice as can be, explained his work and was honest. I can't say enough great things about this company. Don't bother with any other company, this is the one you need for the job!
Working with Carlos and Nick was a great experience. I would refer them anytime.
I totally recommend 5 Diamond for your heating issues. They were prompt to come out and check out my unit. My unit was over 50 years old, they even attempted to find parts, which was a nice touch. When it was beyond repair, meaning no parts on the horizon, they had a replacement unit ready for me and at a great price!! I cannot complain...excellent , prompt and professional service all the way. Fast, friendly, knowledgeable....im very happy with their service.
We could not be happier with our choice of 5 Diamond. Carlos and the entire group were great. We had 3 Fujitsu Mini splits installed and an old wall heater taken out. The job took a few days to complete and everyone that worked on it was friendly and courteous. The installation looks great and we are extremely happy with the product and the work they did. At the time of installation they were unable to test the units ( we were having the house rewired at the same time) so we did have a small problem with the condensation lines once the units were up and running. It of course happened on Labor Day weekend. We contacted them after hours and left a message, the next a.m. they were out there to start fixing the problem. It ended up taking 2 days of the long weekend to resolve but they were there to make sure it was takin care of. Trust me when I tell you I will never use anyone else except 5 Diamond for our HVAC needs!!!
This company has fantastic customer service! I purchased a Groupon for an ac tune up. Carlos called me back to schedule an appt next day. Daniel, the technician, came to my house and was courteous, prompt and professional. He answered all my many questions thoroughly and patiently. Will definitely call them again if my ac or furnace acts up!
This is a great company. Phillip came out and fixed a problem with my old HVAC unit that had been plaguing me for awhile. It was a tricky one, and he figured it out and got my AC up and running again. They were on-time, fast, friendly, and the price was right. They saved me a lot of money. I highly recommend 5 Diamond!
Love this company! Nick helped us out today. Called in the evening & they called back first thing in the morning. They were able ro get right over to me even in this heat wave! Super friendly & knowlegable. He honored the Groupon price for the visit. Will definitely use these guys again. Paying was a snap with the app they have. Great experience all around.
These guys are the best. On time, super friendly professional service! From the text message showing the tech who will be arriving at your door to your final super satisfied handshake, they set a standard that few, if any, can match. Fast and thorough. Definitely the company to choose when needing any of their provided services!
Purchased a Yelp Deal Booked via Yelp Eddie arrived early in the designated window. Very friendly and professional. I highly recommend their service. I used the Yelp certificate and the price was right!
So I purchased a carrier AC / heating mini split for a jaw dropping low price from a vendor. I decided to install it myself since it did not seem too complicated. Eventually, I saw the need to hire an electrician to complete the wiring. However, the unit would not work after the electrician finished. So I called Carlos and he quoted me a reasonable price to finish the job. Phillip came over and realized that the electrician had not wired 2 wires properly. After fixing that issue, my AC worked perfectly. Very happy customer.
Ryan and Nick were great! Got to my home on time with all the correct tools, were very friendly, extremely professional! Fair priced and gave great advice! My AC is running great and house smells amazing! Thanks so much guys!
Absolutely the finest service I've found locally. Used the more well known companies before and they were good, but these guys have by far the best service, attitude, and price. They repaired my home AC compressor under warranty even though they were not the original installers. They went above and beyond to get it done early and within my travel schedule. The price was way reasonable and fair. Nick and Carlos have a good shop going and I encourage anyone needing HVAC services to call and let them bid your job.
We have an older AC unit in our house that we wanted to have a good once over to make sure we could keep it running a bit longer. I sent a few messages out on yelp and Carlos got back to me within 30 minutes of sending my message. I got texts to confirm my appointment and a text that my tech was on his way and his name. Nick came out and did a thorough inspection of my unit, the compressor and all the stuff i know nothing about :) He took the time to answer every one of my questions as well as a few random ones. He recommended some filter change schedules and also gave me a few options to get new ones since they are an odd size. These guys are top notch and I could not recommend them more.
I had problems with my furnace. I contacted 5 Diamond and Carlos returned my call and made arrangements to assess my furnace. He was very informative re: my issues and presented options. I opted to purchase a new unit and Nick and Carlos came out to assure the furnace would be installed as planned! Now, several days later the new furnace is functioning very well. Highly recommend this company. Thank you! Missy B.
Had Nick come out to La Jolla to fix our heater. Everything throughout the process was extremely well communicated and I never felt as though I couldnt understand what was being done in my home. On top of that Nick was one of the kindest people Ive ever had the pleasure of doing business with. Defintely recommend this place
These guys are life savers! Over the holidays, I'd installed a Nest thermostat. I did it myself, meticulously following directions. But it wasn't heating like it should. I called one of the big-name HVAC services (you probably know their TV jingle), but they didn't work on Nest equipment. So I got 5 Diamond's number from the list of service pros on the Nest website. Carlos answered on the first ring and said they could fit me in today! Nick showed up right on time and couldn't have been nicer or more helpful. He explained my system to me, so I would understand what he was doing and why. It took some detective work to figure out the issue, including getting up on the roof, but he fixed it. And the charge was very reasonable. This is a small outfit with no fancy TV jingles--just prompt, competent, reasonably priced service. I will definitely use them again!
I had an air conditioner at a rental unit stop working. Carlos got back to me within an hour or two, with the most competitive price I saw (of about 7 bids). The tech, Eddie, showed up early in the designated window. He quickly diagnosed the issue, fixed some damage that he didn't charge me for, and went and picked up some parts. Eddie returned quickly and completed repairs. Total cost was under what I expected. The tech was polite, friendly, and worked quickly. I am 100% satisfied. I will use them again.Update in 2018: We have used this service three more times on three separate properties. Always A+ work and low cost.
Very impressive company, great experience!!! Total package... from business relations to system installation expertise to courteous personnel to quality of equipment (York) to fair installed price. My experience dealing business with Carlos is amazing. Very professional, sales support is impressive, and turn around time for replying to my questions is very quick. He tries to call me after every email to discuss further the transaction with much more clarity.And then, on the technical and installation side...Nick and Kelby are the best!!! Nick is very knowledgeable, highly technical, very experienced, and most of all courteous, friendly, and professional. Project finished ahead on estimated completion time.
5 Diamond crew was efficient and friendly. Spent the day installing an air conditioner. Really appreciate the professional job and great customer service. Would definitely use this company again.
Nick has been out to the house twice. Great guy and very honest. The first time to give us a second opinion on an expensive quote. He didn't try to up sell us and let us know our system was working fine. He recommended some upgrades but we held off. A year later we thought our system was broken again. We got a large quote from a competitor for a new system from. We then called 5 Diamond for a second opinion. Nick recommended that we add a return to our system and told us we didn't need a new system. This was a fraction of the cost of a new system. We took the leap of faith and went with Nick's recommendation. Our system is running 100x better. We didn't think our system could work so well. Great team.
Can't say enough about these guys! Nick came out and gave us a great deal on central a/c. No upselling, very honest, and just such a really nice guy. Showed up on time on installation day on time and ready to go. The crew of Nick, Justin, and Eddie worked hard and were all so friendly and courteous. They didn't just install - they had meticulous standards and double checked everything. I wish I could give 10 stars!!! Highly recommended.
My AC wasn't working properly, I was so stressed, I called and spoke to Carlos, who set up my inspection appointment. Nick was the technician who came out to diagnose the issue, he then fixed my AC at the same time, and he didn't try to charge me anything extra. He was extremely helpful, knowledgeable, friendly and super awesome! I will be referring all of my friends and family to them as these guys are pros and they don't try to rip you off. Thanks Nick for making my Friday! I guess I won't be melting this coming weekend!! :)
I found 5 Diamond through Amazon Home Services. Although we didn't end up using them for our actual work, the customer service was great. Friendly phone call response , and in person check in from Carlos within 24 hours. We needed help finalizing the install of our mini-split AC unit, and making sure it was installed to code. It was clear they knew what they were talking about - a welcome relief after working with another provider that came 6 times and still could not finish the job! I would definitely call them back if I need AC help in the future.
All dealings with Carlos, Nick and their staff were prompt, friendly and very professional. They quickly diagnosed our problem and quoted us a fix that we found to be very reasonable after doing some research. They helped us with financing and that went quickly as well. It was a big job and they stayed late and got it all done in one day. I highly recommend 5 Diamond!
I had a very positive experience with 5 Diamond! I needed someone to install my Ecobee and Carlos was incredibly helpful in setting up my appointment and he gave it to me on the same day. The installation was very quick and the technician was very courteous! Would definitely recommend and hire them again in the future! Keep up the good work!
Hands down, has to be one of the best companies I have ever used! My wife and I are expecting our first child so we needed an AC unit in our house ASAP. After shopping around and getting treated terrible by other AC companies we came across 5 Diamond. Carlos and Nick were friendly and understanding to our situation, they personally came out to do the pre-inspections. After deciding what would work with our budget , they were prompt to start the job. During the instillation they showed up on time, were polite, and even brought us breakfast. Everyday they did a walk thru going over, with complete detail, what was happening so we never had a question to what was going on. The units installed were put to the test this week with a heat wave and temps in the 100s. We were ice cool and so thankful we decided to get the mini split system installed , and so fast !!!Like I said before, I have never worked with a better company and highly recommend them for the job. Not only did they walk away with a outstanding working system and flawless craftsmanship, but with my friendship.
It all started with a Groupon to check why our furnace wasn't blowing hot air and to perform a tune up on our lagging AC unit. It ended with the recommendation of replacing our entire 30 year old HVAC system. We didn't anticipate the full enchilada being necessary but it made sense to upgrade and get a fully functioning and much more efficient system. Carlos was extremely communicative and professional, as were his assistants. He worked with us on price and brand we desired, and even had his crew start at 6am on installation day to get the job done in a timely fashion and that worked better for our schedules. Talk about commitment to the customer! While we haven't had the chance to use the AC yet, we've been happy with the furnace during this recent "California cold snap". Thank you Carlos for your professionalism and workmanship. Will be recommending 5 Diamond to friends and will be back ourselves for our heating and cooling needs!
I wish there were 10 stars to give 5 Diamond. My AC went out in the mist of a heat wave on Saturday. Carlos returned my call the same day and offered to bring me a portable unit until my appointment day. They gave me a fair price on replacing the 1988 condenser. Nick even lowered the price once they started working and noticed I didn't need certain parts. I'm always particularly impressed with servicers who give you a fair price and even lower it if they see they can save you money.
My a/c had been out for a month and couldn't handle the heat wave we had. They were quick to send a technician out to attempt to assess the unit. The first guy wasn't confident and the next day Nick came out. He was extremely knowledgeable and helpful. Nick answered all my questions, explaining everything and what needed to be done. Great service.
Excellent service. Very nice, pleasant and professional. Had a complicated AC issue that they were able to solve in a timely manner.
They installed new HVAC for our condo. Great job, very professional and knowledgeable. Very competitive price. Highly recommend them.
We had a 20 year old A/C system needing replacement and we were also looking to replace our old noisy whole house fan. We shopped 5-6 other companies and decided on 5 Diamond based price and professionalism. Carlos, Nick, Brent, Shelby, Justin and the whole crew were all awesome from the start (during the quote process) all the way through the finish with installation completion. We are very happy and I would definitely recommend them to any of my friends...H. DeckerI would like to shout out to 5 Diamond and mention we shopped quite a bit and that these guys were really respectful, kind, helpful and available during the sales and quotes, measurements, and install of our 5 ton 16 seer AC System/Furnace with Nest thermostat and whole house Quiet Cool Stealth fan and sound dampening closet lining. Our needs included permit, a bit of framing with texture and moving the house fan control switch placement. They met our low pricing needs along with a goal to save money on our monthly utility bill. They did their work in a friendly and professional manner. Very pleased they were quick and kept everything neat and clean. We are certain that we have just received the biggest bang for our buck with 5 Diamond...Grins and smiles to these guys!R. Decker
We are overseas and our rental unit ac was causing issues. We own a property in downtown San Diego which means ac units are tied to the building and their cooling towers. Our previous company let me know that they no longer service those types of ac units. OK no big deal, until you realize that a majority of ac tech companies do not touch this type of system... Well after multiple contacts and stress we found 5 Diamond. Carlos was prompt and extremely helpful thru the whole process while we are overseas and helped fix the ac for our tenant.
Best service I have ever encountered in this business! Justin the tech was on time, professional yet friendly! Offered good advice and let me ask him a 100 questions. He checked the system inside and out. Checked the temperatures and went back through the house to make sure my vents were all functioning properly! Knowledgeable and courteous!!You are lucky to have this gentleman on your staff! Bravo. Job well done. I will recommend to everyone I know and call back when/if I need service. An honest HVAC company !! Who knew!!
These guys are awesome! Had two jobs done by them and both times I was happy with the outstanding work done. They came in and fixed a horrible AC installation done before purchase of my new home. And also save the day when that same AC went out. I recommend these guys if you are looking for quality work for a decent price!
