Georgy from Diamond HVAC arrived on time as scheduled and he immediately figured out what the issue with my hvac was. He started the system and never made me spend any additional money that was not required. My system is old and needs replacement eventually, but he said it’s good for a few months until I do my house remodel in a couple of months anyway. I would highly recommend their service. As a realtor, I’ve used them on client sites as well and they have always turned out to be professional and reliable.

Diamond HVAC did an incredible job cleaning and doing some maintenance on a two zone mini split at one of our properties. The coils were baked in dust and cat hair, and when these guys finished, everything looked brand new!

They showed up on time, were very professional, and resolved the issue while being the most reasonably priced out of 5-6 other companies I contacted. I'll definitely be calling them in the future!

Their team was very professional. Compared to the other two companies that wanted to charge me over 5000 dollars to replace the furnace these guys did a through inspection and charge a very fair rate. They do very honest and good work. I would recommend this company to anyone who has HVAC problems.

I give my best recommendation to Diamond HVAC!!! We were looking for the best person to install a ducted mini split system in our back house that our daughter just moved into. We completely replaced the gas furnace back there and he did it while saving us money with a specialized solution. He was a great pleasure to work with and have around for the few days he was here.

After the project was done everything was cleaned up. The mini split system he installed is working just fine and I enjoy using it when the heat wave comes around the in the afternoon cause I can just sit around and chill with a nice cold drink in my hand, while the cold air hits me.

I wholly recommend DiamondHVAC for all your HVAC needs! It was 90 degrees and our AC stopped working. Diamond HVAC was able to fit us in on the same day (when all other companies that responded to our inquiry couldn't fit us in until the next day.) The owner, Georgy, showed up on time and was very knowledgeable. He took his time to explain what the issue was and luckily had the part that was needed in his truck. It took him less than an hour to finish the work and get our AC back up and running (and a total of 2 hours from the time of contact to having our AC repaired!) We appreciate the swiftness in getting our AC repaired and the excellent customer service. Thanks again, Georgy & Diamond HVAC!

What can I say about Diamond HVAC? Let start off with the customer service, from phone call to the project being finished they were always informing us and making sure that we were kept in the loop at all times. Which is very important because this year has been a big one for us when it comes to renovation and adding a new HVAC system for our home. We needed to install a 3 ton unit because the airflow of the house was not reaching the far end of the house so they were able to add ventilation system throughout. To make sure it reached to the backside of the house, our home is about 3800+ sq ft so you know we needed two units. Beyond blessed to have found Diamond HVAC, will be using them and recommending them in the future.

When my old furnace stopped working, I had Diamond HVAC come & fixed the problem. However, they strongly recommended to replace the 38 year old furnace & they showed the danger of CO2 leaking. After thinking about their advice & two quotes from bigger outfits (their quotes were very high & unreasonable), I got the quote from Diamond HVAC & decided to go with them.

They came & did an amazing job with finesse & solid work. Along the way they explained each step of the installation process.

I would give them a 7 star out of max 5 stars.

Excellent professionals.

Georgy and Nick was so helpful. They showed up on time, cleaned the heck out of the system, and explained what needed to be done to keep the system in good shape.

My heater stop working and I got a quick response from Diamond. Georgy, the technician arrived within one and half hours upon request, and identified the issue that board needed to be replaced. The best thing of Diamond is that they have boards(all kinds of them) in their van and with a good price(less than $100). Georgy was able to replace the broken one with a new one and my heater was back on running again. Thank you Georgy, thank you Diamond.

Here you can find out answers for frequently asked questions

Our company offers a permit obtaining process for the installation of equipment. The process of obtaining a permit includes the preparation of all documents, passing the inspection and HERS test. Yes, you can apply for a permit yourself, but it requires some knowledge and skills to prepare all the documents correctly. As a rule, this process is entrusted to a company.
If any equipment emits carbon monoxide, even in small doses, it is harmful and dangerous to health and even life. If the equipment starts to emit small levels of carbon monoxide, it will increase carbon monoxide emissions. The main danger of carbon monoxide is that it cannot be felt. You can't rely on home carbon monoxide detectors, as they can't always respond correctly to emissions. Heaters should be checked with professional equipment for carbon monoxide emissions at least once a year before use during the winter season. When equipment emits carbon monoxide, then in this case we do only the replacement of equipment.

Maintenance includes checking the operation of the system, its condition, and recommendations for future maintenance. A complete list can be provided by our representatives.

HVAC contractors are trained and licensed professionals who know how to size, design, and install heating and cooling systems. They are trained in proper handling techniques, ensuring that your system is installed properly and functions efficiently for years to come. They also keep current on industry regulations and standards. What’s more, local building codes govern the installation of HVAC systems. Often, unlicensed contractors may not be aware of these codes and how they apply to your project.

Licensed contractors meet your needs while remaining compliant with these codes. Also, for an HVAC contractor to maintain their license, they must continue their education by participating in ongoing training provided by their employer or professional trade organization. It ensures that they stay informed on all current industry regulations and standards and know how to apply these to your specific situation.

When you hire someone with professional experience, you know they will do the job right the first time. These contractors have worked on all kinds of systems in all types of homes. It gives them experience and knowledge that you can’t get by simply reading an owner’s manual.

It saves you time and money in the long run because you don’t have to worry about redoing work if it is not done correctly. Additionally, when something goes wrong with your HVAC system, a licensed contractor can diagnose the problem quickly, saving you time and money. In addition, they can advise on future repairs or maintenance that you might need before issues arise.

Licensed contractors have years of experience installing and maintaining multiple types of HVAC systems in all kinds of homes and businesses. They know what types of systems work best in different situations and can recommend an energy-efficient unit that works for your home’s unique layout. Licensed contractors can also access quality parts and equipment from a trusted network of suppliers while the unlicensed ones do not have this option and use non-original parts.

From their experience, they have access to original parts that are not available at hardware stores or online retailers such as Amazon. Additionally, licensed HVAC contractors have all the tools necessary to complete your project correctly. It’s not only more convenient to hire a contractor who already has the tools he needs, but it also means you won’t have to spend money on equipment for just one job.

A licensed contractor must perform work that meets the standards set by the licensing board. In addition to the manufacturer’s warranty on your equipment, the contractor will offer a workmanship warranty on their installation. As a rule, in the case of a warranty claim on equipment, the manufacturer checks who installed the equipment. If the installation was performed by an unlicensed contractor, the warranty may be invalid.
