My young daughter had a technician come out... who said her thermostat was broke…read more Okay he replaced it and got it running. Thermostat was only a year old, but how can you prove it worked, you have to trust the technician especially when there's no air conditioning and you just want it running. While out checking the unit he noticed a corner bent and started telling her a stupid scenario of a dog rubbing up on the unit and peed all over it and to get it cleaned out it would be somewhere over $1,000. Come on, what lengths of lies you sales people go to. I told her to stay away from you guys and would recommend someone else. I would not recommend Anderson at all. It's hard to find honest heating and cooling technicians. Anderson is not one of them.

Stay away from this business! My entire cooling and heating system was left in an inoperable state…read more I called for a diagnostic of the air conditioner today because cool air isn't coming from the vents. I was told the diagnostic would cost $149. I asked to be informed of any repairs that had to be done. Technician checked the system and recommended replacing unit. We discussed replacement unit and cost. I was ready to pay deposit. In the next 10 minutes I was told that the model I selected is old and not available. New model costs $1000 more. I asked for a proposal to decide later. Technician told me that the visit costs $396. He said that he fixed air conditioner that was not working. He never told me that he is fixing anything. Through our the visit it looked like he was figuring out the problem. I talked to the owner and we agreed that any repairs that were done will be undone so that I do not have to pay for repairs. Then the technician removed all the wires from the board making both heat and fan unusable. He did not just undo the "repairs", but made entire system unusable including fan and heat which were working before his visit. See the photos to show what was done!

Reply to 2 reactions from Harmonic on my 1 star review…read more 1. A. & K. claimed A. fixed my heater Tuesday; lie. Bad customer service. Harmonic deserves 1 star, but all the starts below 5 are NOT indicated on the Google graphic of the numbers of review stars 1-4: false. 2. I never promised a review pull-down for a discount. My husband & I have better things to do than having an "agenda" as Harmonic accused. My husband was on a business trip. 3. I never called for an emergency repair. I did not switch from repair to cleaning & maintenance. I asked A. if C & M was possible afterward, unaware of 2 more with no heat. Harmonic called me "selfish" for this. 4. Any possibility A. and K. have unconscious biases towards people like me? They accused us of "manipulating" what? To save a few hundred bucks, while we spent in the tens of thousands at Harmonic's better former (aquired) company) you imagined up? 5. How could Harmonic accuse me of lying about my pain. Because I was able to and had to carry my 10 lb dog for a short moment because of her barkin? Why do I even have to explain my chronic severe back pain and mostly failed back surgeries and weak immune system? 6. I had no "agenda," but getting my heate fixed. I am not playing any "game" as accused. I am standing up for myself. 7. K.'s statistics on the number of my Goole reviews are false. 8. A. & K. are the ones who were "aggressive, harsh, unethical, disrespectful, and manipulative." Stop projecting and gaslighting. I wish I would remember to record conversations when I am alone with a person like A. Why did K pull down his absurd replies on Google?

I needed a humidifier installed in new construction home. I'm extremely pleased with my experience…read more They explained things patiently and thoroughly. When they came for the install, they informed me that the original humidifier was not the best fit. Rather than installing it just to get the job done they paused. They recommended a different option that was actually a lower cost and that they would have to come a different time to install it. This shows their dedication to customer satisfaction and making sure the customer has the best product to address their needs. Highly recommend them.

As a fellow small business owner, I feel obligated to warn others about our experience with this…read moreHVAC/R contractor. Over more than a decade of managing vendors, this has been hands down the most disappointing and unreliable company we've dealt with. We initially entrusted them with all our heating, cooling, and refrigeration needs. Unfortunately, what followed was poor communication, subpar service, and a complete lack of accountability. When issues came up--which happened frequently--they were more interested in deflecting blame than fixing the problems. Over a year, they raised our service rates by 25% without any notice or explanation, and when I reached out to ask about it, they never responded. I also requested several quotes that were never provided. As a busy business owner, I shouldn't have to chase down contractors just to give them our business. Even worse, they billed us for services that were clearly not performed. I verified this myself--twice--and one time had to bring in a third-party HVAC tech to confirm (with photo evidence) that a rooftop unit hadn't been serviced as claimed. Despite being presented with clear proof, they refused to acknowledge or resolve the issue. After nearly two months of delays and rescheduling for a correction that never happened, we finally hired another company to finish the job. Their refrigeration work was even more troubling. They miscalculated and mis-sized a walk-in freezer, resulting in a system we had to completely replace. They relied on bad measurements and passed critical sizing calculations to a supplier instead of doing it themselves. Even when I showed them accurate specs from the equipment manufacturer, they pushed back with excuses instead of taking responsibility. To make matters worse, they submitted a bid to replace our walk-in cooler and freezer with dimensions that were entirely off. Had we accepted the quote, the units would've physically not fit the space--basic measurement errors that would have led to a major installation failure. The most aggravating part of all this has been their tone: dismissive, defensive, and utterly lacking in professionalism. If you're considering this company, I urge you to think twice. When things go wrong--and they very well might--you'll be on your own. You deserve a vendor who respects your time, your business, and takes pride in getting it right.
