RESIDENTIAL BUYER BEWARE. In 2018 my very old AC unit was on it's way out and so we looked into…read morereplacing the unit. Doing our due diligence of obtaining multiple quotes we found Mike and Black Diamond. We ended up using them as we thought we had a good feel from them and the price happened to be the one right in the middle. Mistake. Fast forward to 2023 and suddenly there is no more cool air. Uh oh. After asking around and speaking to Mike finally someone came out to check it out and long story short filled it with freon and was told to monitor for a leak. Well it worked great all summer long but by this summer no more cold air. Here's where the problem starts. In 2023 there was a little hemming and hawing about coming out to fix because they were busy and said we were out of warranty which isn't true. Now in 2024 we faced the same thing only worse. As a single woman I tend to get more of the runaround from male businesses, I'm also going to school and working, so pretty busy and asked my Dad to contact him. We got a date, June 20th, on the books for them to come out and fix the leak etc. Well June 19th rolls around, and I'm told the next day appointment is to be cancelled due to a Covid out break at a facility they are under contact with. Ok. Well i was going out of town. So I was told just text when I'm back. No, with a dog and 3 kids this needs to be on the books. So I'm asked for 7/3 which I can't do and schedule for 7/1. On the 1st I'm told they aren't coming again, only this time it's because they didn't finish their Friday or weekend work. But he'll be here 7/3, never took it off the calendar. Suspicious of not ever actually scheduling the appointment on the 1st much? Well guess what its 7/3 and I sent a text and my dad called and no show. No response. Ghosted. This was literally as short as I could make this review. There many details to the interaction in 2023 and 2024 that could be spoken about but you get the point. They don't care about the residential units and people they've worked with or following through on warranties. It's not about integrity or being a business of its word. For Black Diamond It's all about the contracts they have with big companies or developments and money. We will be complaining to states licensing board and BBB.

Our heater and air conditioning were functioning properly, but we received a flyer from a…read morewell-known company offering a low-cost inspection of our unit. Wanting to be responsible, we decided to contact them for the service. When the technician arrived, the heater was working, but a few minutes later, it stopped. What a coincidence! The young technician remarked on how fortunate we were that he was there to diagnose the issue. He inquired about the age of the unit, and when we told him it was 22 years old, he said it was no surprise that it had stopped working. He proceeded to check the unit and listed several problems: it needed a new ignitor ($458), a cleaning of the blower ($510), a new blower motor ($1,100), and a new control board ($1,376). The total for all of this came to $3,444! He then suggested that instead of spending that money on repairs, we should consider investing in a completely new unit that his company could install for about $25,000. We told him we would think about it. Afterward, we decided to call Fairview Heating and Air Conditioning. They sent out Keanu, a nice, intelligent, and honest young man. We explained our issue with the heater not functioning. Keanu quickly removed the back of the unit and, within seconds, said, "I know why your unit isn't working. The gas lever is turned off!" We were shocked--how could that have happened? I immediately turned on the gas valve. When Keanu then checked out the unit, everything cycled properly and he was able to verify that everything was working normally -- just like it was before the big company's visit. Keanu was very knowlegable and explained to us -in terms we could actually understand- how our system works. Needless to say, we have found ourselves a new heating and air conditioning company!

I was a new homeowner in 2022 when Vic (the owner) and his company, Elite Comfort Systems, saved my…read morefamily (including the feline members) from sweltering in 100+F degree weather by diagnosing and repairing my air conditioner. Since then, they've serviced the almost 22 year old system at my home, nursing it along. With each semi-annual "check-up" service, they advised me on what I needed to do, and what could wait. When funds were tight, they suggested stopgaps to help. Because of this history, when Alex showed me that my heater was leeching carbon monoxide into my home, I knew I could trust him. While I waited for my appointment, I was provided with space heaters gratis. This IS an independently owned business, and they treat customers like family. Ozzy (Osvaldo) and Anthony installed a new heat pump and air conditioner for me last week. They were at my home three days. Not only were they professional, friendly, and polite, they were also respectful of my home--taking time EVERY day to cover my carpeted areas, covering their boots as they came into and exited the house, and cleaning up any installation debris before they left each day. Ozzy and Anthony discovered that a part of the original system was not going to work as efficiently with the new system (the dampers) given the difference in the size. Ozzy explained the difference to me, noted the cost, and the pros and cons. He didn't pressure me to upgrade the items but he made sure I had enough information to make a decision. At the end of the installation, Ozzy took the time to show me how to use the new digital thermostat controls and gave me tips on how to use the system economically. He provided me information on how to follow up if there were ever any problems. Just like other times, Vic called a few days later to see how things were going (I missed the call, but still...so so kind and thoughtful). It's a lot of money to replace your entire HVAC system, no matter which company you use, but hiring one where you know you can trust the company. Simply put, you'll never have worries about trusting Elite Comfort Systems.

Their technicians are always friendly, professional, and, most importantly, highly skilled. They perform a thorough inspection and maintenance of the entire system, taking the time to clean and check everything carefully. When they're finished, the air is noticeably colder and smells fresher. Unlike some companies that rush through the job, Blue Star takes the time to do the work right. What I appreciate most is that they never try to upsell parts or services that aren't needed. Their honesty, attention to detail, and quality workmanship have earned my trust, and I highly recommend them to anyone looking for reliable HVAC service.

Jeff was proud of his employee and the longer I stayed on the call, it was evident where Colton gets his excellent customer service. Blue Star will be my first call for my future HVAC needs.

Terry, the technician, is kind & respectful. He comes to do the routine check up on our home system throughout the year before big weather seasons.

Short version: Terry, Trevor, and Ricardo did a fantastic job! Professional, punctual,…read moretrust-worthy, and accommodating. I cannot say enough positive things about the job they did and how well organized and efficient they were. I would highly recommend them for anyone in need of HVAC work. Long version: I had Oakley heating and air come by to evaluate and change my central air conditioning, zoning of the house (upstairs and downstairs), and put a mini split system in the garage. It was a three and half day job! Even though it was a large project, I felt involved in every step. The removal, installation, and zoning went without a hitch. The crew was nice enough to wear shoe covers and cover the house with blankets as to not cause any damage or bring dirt into the house. A big plus was that Terry was respectful of my time and my love for cars. It rained on the days of installation and he asked if it was alright if I parked my cars outside in the rain so they can stage the large equipment. It was refreshing to see they were not just interested in doing the job, but also to take care of the actual homeowners. Again, I could not recommend Oakley Heating and Air!
