I called Cold Cloud Mechanical today based on their excellent Yelp rating for two issues: a…read moresuspected freon leak in my living room mini split, and water leaking from my son's bedroom unit after about 20 minutes of use. Technician Arsen handled the bedroom unit well. He found the drain hose was clogged and mounted too low, cleaned it out, adjusted the mounting height, and confirmed it drained properly over a 2-hour test. The living room unit is where I'm disappointed. A technician from my home warranty company had already confirmed the unit, less than a year old, was completely empty of freon. Arsen couldn't initially find the leak and charged me to vacuum and recharge the system, with no warranty since the source was unconfirmed. During that process, he found the actual leak in a copper line under the house. Once identified, he refused to go into the crawl space to fix it and said no one else at the company could either. That doesn't add up: just months ago, five workers from another company spent a full week under the house for a seismic retrofit, moving freely through the entire crawl space without issue, including the area where this leak is now located. I offered to pay extra for him or anyone else to complete the repair and was still turned down. Instead, he recommended replacing the entire unit for $5,000, which doesn't make sense for a nearly-new system with one identified leak point. I'm now out the cost of a recharge that didn't fix anything and came with no warranty, and I still have to find another company willing to go under the house and finish the repair Arsen already diagnosed. I appreciate the diagnostic work, but a company that installs mini splits should have someone who can access a crawl space to tighten a fitting. Choosing an upsell over a specific, identified fix is why I can't rate this higher. Update: The owner, Alex B., responded to this review quickly and personally came out to fix the leak. He accessed the crawl space without any issue, repaired the fitting in a few minutes, vacuumed and recharged the system, and tested it to confirm stable freon levels and cold air output. It's a straightforward fix, which makes it more frustrating it wasn't handled this way from the start, but I appreciate the owner stepping in directly to make it right. Updating to 5 stars for the responsiveness and quality of the resolution.

Fixed the issues but not the smoothest experience and prices felt very high. I guess it's normal to…read moremark up prices but when you know how much these AC parts cost the prices feel kind of crazy. Ended up paying $1,300 to replace a transformer, capacitor and fuse and to hose the outside unit down with water. Also wanted to charge almost $500 to "chemical wash" the unit, which is something I know you can do yourself pretty easily. I know most places charge the same but it all feels so much like a scam when these parts are all no more than $40-$50 each max. When booking I also go left on read when messaging via Yelp and had to call 2 hours later for them to actually book and send a confirmation. Then they said the tech would text 30 minutes before arrival and they did not, and when I told them I was expecting a text heads up they said they "didn't receive these instructions".

I am so happy we found Robert Hall and Sons!…read more We had a very old, but still working, HVAC system. This summer, after going through our warranty company for a check-up, the technician ended up blowing our compressor. We then spent four visits trying to get the AC working again. It never did. Unfortunately, we realized too late that we had been completely scammed. While trying to get it fixed in August, we were also ghosted by another company right in the middle of a heatwave. Needless to say, I was stressed and overwhelmed. At that point, we decided to replace the entire system because we no longer trusted putting more money into repairs. That is when we called Robert Hall and Sons. Mike came out for an estimate, and right away, we felt like we were in good hands. He patiently answered all of our questions and, true to his word, we had a written estimate a few hours later. The estimate we received was beyond reasonable. After we submitted the signed contract, we were scheduled for installation about a week out. A few days later, I saw that another extended heatwave was in the forecast. After everything we had just gone through, I was not prepared to go through it again without working AC. I explained the situation to Mike, along with our HOA requirements, and he worked with us to make sure everything could be done as quickly, quietly, and efficiently as possible. His crew was amazing. They worked quickly, but thoroughly, and had the entire system installed in under three hours. I honestly could not believe how smoothly everything went. I cannot stress enough how professional Mike has been throughout this entire process. After the nightmare we had just experienced with other companies, it was such a relief to finally deal with someone who was honest, responsive, and did exactly what he said he would do. We now have a new HVAC system, a cool house, and peace of mind. Most importantly, we trust that if anything does go wrong, Robert Hall and Sons will be there and make it right. I would absolutely recommend Robert Hall and Sons. After everything we went through this summer, finding a company we can actually trust means everything.

If you're having any HVAC issues, definitely put Manny's HVAC on the top of your list to call…read more My AC stopped blowing cold air in this heatwave. Jerry diagnosed that it was a low capacitor and freon leak, and that the fan motor was not broken like others have said. Other companies needed me to purchase additional parts to get it fixed but Jerry was able to get my AC working the same day. My HVAC unit was nearing it's end of life so I was also comparing bids on what made the most sense for my condo. Jerry offered to temporarily 'lend' us a new capacitor and pumped freon into my system at no charge while I made the decision whether I wanted just the fix or to replace my system. If I decided to just go with the fix, I would pay for it of course, but if I went with replacing the system, they would just take back their capacitor and reclaim the freon. This was a hugely appreciated gesture. Their HVAC replacement proposal was also very competitive. I ultimately decided to replace the system. The experience was pleasant from beginning to end. Cecilia is the one who helps schedule at the office, very friendly and responsive. Jerry was the technician who helped us diagnose the issue and coordinate the HVAC team. He was friendly, transparent, and always responded quickly to my texts/questions - great communication. The day of, the workers Juan, Victor and Andrew were very professional. Maintained constant communication the whole time, kept me updated on the process and what they were doing. They wore booties inside, protected the floor with tarp, and were just very careful in general. The installation of the unit itself is very professionally done, and they vacuumed everything and cleaned up afterwards. They even explained how to register the units for warranties etc. They were able to remove the old AC and install the whole new system the same day, roughly ~5-6 hours including the crane to get the units on/off the roof of the condo building.
