"On a recommendation, I called Marcucci to recharge a wine cellar AC unit. When the service man came out, he quickly advised that the type of unit I have couldn't be open or recharged in a reasonable manner. OK, but that could have been determined at the phone call by asking me what kind of unit it was (an experienced service man would have known this). They charged $150 for the 15 min service call to tell me that. Not happy."

Learn about Sandium's whole-house approach and the road to healthier air and lower bills.

"I get why Sandium has great reviews. They're install services are great and since 99% of systems probably work reliably for years that's the extet of dealing with them. But their after service support has been awful and if you're stuck with a system that fails prematurely then good luck. We paid $40k+ for a brand new Samsung heat pump system and all new ductwork last year. One of our attic air handlers died on Dec 11 taking out our bedroom zone and leaving us with nothing but space heaters for our bedrooms during our first winter with the brand new system. Took till early Jan to finally get it fixed which left us with space heaters over the holidays. Seems crazy to me when we paid a very significant premium for sandium over other competitors truly believing they were the best. Once the temporary fix was in the technician realized that the bearing failed because the cabinet was deformed. That could only have happened in original transit. They ordered a new air handler which took 3+ months to arrive. Now I'm being told this can't be installed till June or July because they're too busy. Given the system is likely to fail when under load this means there's a pretty good chance I'll lose cooling during a heat wave before they can get the new unit in. I'm by no means excited to get this new unit in as it'll be very disruptive and require removing our existing closet built ins but it has to be done. This whole situation is incredibly unacceptable. To take 6-7 months to fix a brand new system is crazy to me. I've really tried to be patient on this and it pains me to leave this review but hopefully anyone who reads this can see how unacceptable this situation is. I'm not even going to get into the back and forth with Samsung and the supply company since I made the check out to sandium and so they should be responsible for the system. When you hire an hvac company, turn around time for fixing things matters. I totally get that things can go wrong but the response to things going wrong matters. Sandium is too busy with new work to bother with that. It's not like fixing this is a favor to me. It's getting my system into the condition it should have been in on day 1."

"Ezra and Charles are very friendly and personable. That is, when they want to take your money. What good is a 12-year warranty if you start ignoring your customers at 2 years. I needed my HVAC replaced. Because the HVAC sits on my roof, I decided to redo the roof too. Ezra and Charles came out and were really friendly so I immediately had a good impression of them. Even though it would’ve been cheaper to go with a roofer and a separate HVAC company, I decided to go with Landmark Construction Crew, aka Landmark Energy Upgrades. I figured it would be a more seamless process for one company to do both. I got this done in December of 2016. The thing with a roof is that you don’t know if it’s a good job or not until it rains so I waited to write a review. Around January 2018 ( a little over a year later ) we got some much needed rain but unfortunately, I had a leak coming from one of my vents. I emailed Ezra and he sent out a roofer. The roofer came, looked at the vent, jumped up on the roof for ten minutes and said he was done. Months later, it rained again, it leaked again, I emailed Ezra again. I decided to take a closer look at the vent and noticed that there was sunlight in the ductwork. I figured sunlight equals gap somewhere. When the roofer came, I told him and he said it’s nothing, probably just a reflection, without even taking a look. Then the roofer tells me that the next time there is a leak, I need to call the HVAC guy because it’s not a roof problem. I couldn’t believe it so I told him that HIS company IS the HVAC guy!! I used one company to do the roof and the HVAC so there is NOBODY else to blame. So, he jumps back on the roof and was done and gone in 10 minutes. About a month goes by and the rain is back and so is my leak. It’s 2019 so it rained a lot this year. Good for California, bad for me. So, I emailed Ezra again. After a few weeks, no reply. So, I email him again with pictures, a few more weeks go by and no reply. So, I call him and he picked up the phone. He sounded surprised to hear from me (probably didn’t recognize my phone number) and I start telling him about the leak. He said he didn’t get my emails but just text him my address and he’ll send somebody. A couple of weeks goes by and nothing. So, I text him again and after weeks and weeks of waiting, no reply. I’ve emailed, called, and texted so, at this point, it’s very obvious he’s avoiding me. If you are looking for a friendly company that is willing to take your hard-earned cash then Landmark is for you. But if you’re looking for a company that is accountable for their work then look elsewhere. I know I am."
