I've found an excellent HVAC service provider in Diamond Air Services. Our initial call was answered promptly, and Anthony provided us with thorough knowledge and information about the services they offer. This decision turned out to be a game-changer.

The quote we received was very competitive, and the technician, Steve, came highly recommended by Anthony. The quality of work was exceptional, and our home benefited greatly from their expertise.

I've been dealing with Diamond Air Services since 2021 and I'm thoroughly pleased. Their team, led by Howie and Anthony, is outstanding. As a new customer in 2021, they installed my home's heating system and provided annual maintenance. The staff is friendly and efficient - it feels like one big family. They respond promptly to any issues, always professionally and with a pleasant demeanor.

The service was top-notch, with professionals who showed excellent courtesy and respect for my property.

We had a great experience with this company - they showed up promptly when we needed them most, fixed our AC in no time, and did it with integrity. We're extremely grateful for their honesty and expertise, especially during the heatwave.

I had a great interaction with Diamond Air Services from start to finish. From the initial call to their office, to the sales team and techs who installed my AC, everything went smoothly. They're worth recommending.

Diamond Air is top-notch. They're super professional and respond promptly. I've worked with them on my commercial properties, and they consistently offer the best value. Highly recommend for any HVAC needs.

The air conditioning issue persisted, with water dripping from the roof. It turned out the condensation trap was blocked. The repairman resolved the problem initially, but new leaks started soon after. What frustrated me was the lack of upfront pricing - he claimed he needed to identify the source before quoting a cost. His statement that it should be fixed and an invoice would follow seemed vague, leaving me wondering about potential expenses. A day passed before I received the invoice via email, which added to my uncertainty throughout the ordeal.

The team showed up on time, which was a big bonus. They were friendly and courteous, completing the work efficiently.

I recently hired this company for AC and furnace maintenance, and I'm satisfied with the results. Oscar took care of the job efficiently, including cleaning the outdoor AC unit and inspecting the attic for the furnace. He also replaced the second-floor filters. Overall, a solid performance from a reliable technician.

Bobby from Diamond Air Services did a great job identifying and fixing problems with our A/C unit. His prompt attention to issues ensured our home was comfortable again in time for the upcoming summer. We appreciate his professionalism and reliability.

Technician Oscar did an excellent job helping me with my issue, turned out it was nothing to do with the work done. Very honest and reliable company overall.

Howie and his team were excellent. They kept me in the loop with clear communication and upfront pricing. Despite a few bumps along the way, they resolved everything promptly. Would definitely recommend Diamond Air to anyone.

Anthony arrived promptly for the estimate, addressing my concerns about the condenser size in a small backyard. He explained it clearly using measurements and a ruler. The office staff, Jennifer, was friendly and responsive to our inquiries. Given the competitive quote, we began work the following week. Diamond Air's services have been satisfactory. We'll likely hire them again.

We're pretty surprised that we got such great results with Diamond without realizing it until the crew arrived. To set the scene, we were already shopping for a new air conditioner and furnace because our old one was barely keeping up, but we wanted to be ahead of the game. Our original AC unit was a 1976 Carrier, while the Goodman furnace was around 3 years old. The outside AC unit had a separate fan that was replaced about 10 years ago - it wasn't exactly a well-maintained Frankenstein's monster, but it worked every time without fail.

The problem was that our bill was astronomical whenever we used the AC. We researched 11 different companies and Diamond was the fourth one we contacted. What impressed us most was how Anthony handled the sale without trying to upsell us on anything we didn't need. Everyone else seemed to be pushing for a 5-ton unit or a smart thermostat, even though we already had one installed. Anthony was straightforward, honest, and took pictures of everything he showed us when he went up into the attic. He also worked closely with us to find brands that fit our needs.

When it came time for the installation, our expectations were low because we'd had some bad experiences with other companies before. We weren't expecting much, but what we got was completely different. The two guys who did the job, Will and Carl, seemed like they were married - they worked together seamlessly and communicated effortlessly. They took their time to troubleshoot and game plan, and it showed that they knew exactly what they were doing.

We have a concrete tile roof, which can be tricky to work on. Luckily, Mike was brought in to help with the installation, and he even read up on the best way to handle the tiles from the tile company. The job itself was impressive - the furnace closet was insulated to perfection, and it looked like a work of art.

What really impressed us was how attentive Anthony and his team were. They made sure everything ran smoothly, even dropping off lunch for the crew to keep their momentum going. We never felt rushed or hurried; instead, the job moved at a steady pace. The bosses even came by to check in on progress and make sure everything went according to plan.

We've been through some other companies before that seemed great on paper but turned out to be disasters when it came down to details. There were always errors on the estimates, important items left off, or people talking about things they clearly had no idea about. With Diamond, there was zero confusion - and that gave us peace of mind.

After every visit, Anthony and his team made sure to follow up and address any issues that arose from their previous visits. That kind of dedication is rare in this industry, and it's what sets Diamond apart.

We wish they were more than just HVAC guys because we know we won't find the same level of commitment with other projects around the house. At least for our significant purchase, everything went as it should, and that's thanks to Diamond's honesty and expertise. If you're in the market for HVAC services - whether it's installation or repairs - we highly recommend Diamond. They offer great service, fair prices, and a level of dedication that's refreshing in an industry where honesty is often hard to come by.

Our only regret is not discovering Diamond sooner - but at least now we know what we're getting when we work with them.

We hired Diamond Air Service to install a new AC system in our office. They did an outstanding job. The initial quote was thorough and presented professionally, covering everything needed. The technicians were courteous, prompt, and kept the workspace tidy. Communication throughout was smooth and the project was handled with great care. We're extremely satisfied and would wholeheartedly recommend Diamond Air Service for their top-notch service and quality workmanship.

Jose did a great job fixing the issue quickly, within 30 minutes. He was extremely friendly and explained everything clearly, answering all my questions. His professionalism was top-notch.

Baran, Christian, Jose, and Oscar provided top-notch service installing a new unit in just one day, exceeding my expectations entirely.

They've delivered again - twice, actually. Had an AC that wasn't cooling and they responded quickly, addressing the issue with a live person soon after. Great service from Jose; he sorted it out fast enough to save me from a scorching heatwave.

I don't often write reviews, but Diamond Air has set a high bar. From the initial phone call to the final inspection, their service was exceptional. Our outdated HVAC system had been struggling for months, and we finally decided to get it checked when it just couldn't keep up with the heat.

Diamond Air arrived promptly, and what struck me most was their meticulousness and openness. They didn't just diagnose the issue – they explained why the system wasn't working efficiently and walked us through our options without pressuring us into unnecessary upgrades.

We ended up replacing the system, and the difference is remarkable. The house feels cooler, cleaner, and more balanced than ever. The hot spots are gone, and it's finally comfortable throughout. It's clear they prioritize doing things right and helping people feel at home in their own space.

As a local, family-run business with genuine kindness, Diamond Air has earned my trust. If you're undecided about who to call, this is the team you should consider. They instilled confidence in our investment and genuinely improved our home's comfort.
