"Unbelievable!! Our AC went out last evening and so I called this morning at 8am, having no expectations of having anyone out to service the unit until next week at the earliest. I spoke with Jeremy, who contacted Dan [who has been out previously] and by 10:40am Dan has worked his magic and the house is cooling! It just doesn't get any better than that! They have my complete trust and unwavering loyalty! Thanks Harmonic!!

"Daniel has serviced my HVAC equipment on several occasions. He has always been prompt and thoroughly explains the service he is performing. On this specific trip, he pulled and cleaner the blower cage. All work was completed promptly and a shiny like new blower cage was installed. The furnace runs much quieter now. The bid on the blower cage was completed t the quoted price which was 25% less than was quoted by a competitor. I continue to recommend Harmonic based upon their knowledge and great service!"

"If you are looking for an HVAC company for your repair. Stop right here and look no further. These are the only people I trust to work in my home. The are friendly, courteous, punctual and they fix ONLY WHAT NEEDS FIXING. I have used them several times. They fix issues no matter how little or inexpensive they are. They don't break stuff on purpose or replace parts that don't need replacing like SO MANY other places. My first experience with them tells the story. My AC stops working. I call the first place which tells me there are several items that need replacing. Quoted $4000. I call Harmonic and Daniel shows up. In very little time he finds a broken wire chewed on by mice. Charged $100 for a service call. Right there tells you how trustworthy Harmonic is. Highly, Highly recommended."

"Fantastic Chris. We know that everyone's Furnace & A/C will need replaced EVENTUALLY. Until then, we hope to earn your trust and help make your home "Smarter, Healthier, and More Efficient" in the process. Remember to tell friends about our 3 "Rock*Star Maintenance Plans" that make that annual Furnace & A/C maintenance cheaper, save money on Furnace & A/C repairs, and even provide credits toward a new Furnace or A/C replacement when that time eventually comes. Until then, enjoy the season, and thanks again for the great 5-Star review. "

"It's definitely time to replace that hot water heater. Sometimes the water quality leads to the requirement for more frequent maintenance of our hot water heater and our humidifier. Our "Rock*Star VIP" maintenance plan would be perfect to clean and maintain that hot water heater, as well as the furnace and air conditioner every year. Its the best way to keep it working properly and last longer. "
