Dycus Heating and Air Conditioning Customer Success Stories
Hear From Our Happy Customers
Steve, the gentleman that came out to fix my air conditioner. He was very professional, very nice, just a pleasant person to be around. And he fixed my air conditioner very quickly. And it hasn’t ran this smooth and cool in years. Completely happy with every aspect. I would definitely use Dycus air-conditioning from now on. And very reasonable price. I think it was half the price of my last visit from a different company. Thank you Mr. Dycus
Purchased a Bosch Heat Pump/ AC unit in 2023. The installation was a bit tricky and there have been a few issues with the unit since, but Dycus has always come out quickly and worked diligently each time to ensure the unit was working as it should and that I was happy with the result. Being a small business owner myself, service after the sale is paramount and Dycus excels in this area. The front office people and the techs are very professional and know their stuff. Very happy to write this review.
Been doing business with Dycus for years. Most recently was just a service on a rental property but the tech did a thorough inspection and service, then called me directly. He advised me of the condition of the unit and made reasonable recommendations for its ongoing functionality. The Dycus team including office staff are professional and trustworthy.
We had an absolutely fantastic experience with this company! Doug went above and beyond to make sure everything was done perfectly. He was professional, knowledgeable, and incredibly friendly throughout the whole process. He took the time to explain everything to us and made sure we were comfortable with how everything worked before he left. The quality of the work was outstanding, and it was clear that Doug truly cares about his customers and takes pride in what he does. I would highly recommend this company — and especially Doug — to anyone looking for heating and cooling services. Thank you so much for the amazing job!
I am grateful for the expediency and professionalism of the service call to get my A/C working on a rather hot day. Steve was courteous and pleasant to work with. He took the time to explain things and I thoroughly enjoyed his proactive demeanor. He is an asset to your organization. I will definitely do business with Dycus again.
