Our floor drain started to back up whenever we'd do laundry. Summers was able to get a plumber out…read moreto us right after the weekend, since it wasn't urgent I didn't mind waiting a couple days anyway. Our arrival window had to be moved back a little, but I was updated when I called to check in, no big deal there. Everyone I spoke to was polite, courteous and professional. Our drain needed a quick cleanout and we can do laundry again with no issues. We'll definitely call them with any future plumbing problems.

Summers sent Jason and helper out to hook up the natural gas line to our new pool heater. Jason did…read morean excellent job, making sure that all codes were followed and the installation was leak-free. He even came back out after we had the electric install finished to make sure that the installation was complete and safe, at no additional charge.

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?

Matt is awesome. He is my go to for all HVAC needs. I've had him come out to 2 of my homes now…read more He's kind, honest, and very knowledgeable. The first time he came out, my furnace was not heating. He took the time to teach me how to "fix" it myself. It was a simple clean. He also taught me how to read the diagnostics to determine what's wrong, which has been super helpful in the small quick fixes I can now do myself.

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.
