Unique is quick to respond, efficient, and trustworthy. We have a great relationship with our HVAC service provider! Thanks for the good work!
I recently had the pleasure of hiring Unique Heating and Cooling to install a Bosch tankless water heater in my home, and I couldn't be happier with the experience. From the moment I contacted them, their customer service was exceptional. The team was fast, friendly, and very knowledgeable about the products they offer. They took the time to explain the benefits of the Bosch tankless water heater and answered all my questions thoroughly.
Our tech, Mitch was very professional! Arrived when he said he would, explained exactly what he was doing and made sure we had no questions before he left! Highly recommend Unique!
Milo came and diagnosed the problem with the cooling. He was able to fix it and make some recommendations. Very friendly and professional.
The best heating and air company! From the phone call through the visit, they are courteous and professional. On the day of the service, they call when they are on their way with the expected arrival time. Tech covers his shoes before walking in your door. They are friendly and very professional. Best decision we made when looking to have a new heating and cooling system put in several years ago. Highly recommend this company for all heating and cooling needs
I had a great experience with this company. While doing a routine maintenance of our mini split, the technician found an issue causing a refrigerant to leak. Dakota was prompt, personable, and professional. He told me upfront my expected cost and how long it would take to fix. I highly recommend their services and plan to use them again.
Well they tried but not hard enough. I had three different technicians and all three just told me that is how it is everything looks good. But it was not good. I finally had to call the best in St. Louis and they were here for 2 hours and now I’m very happy. They used a hose to spray the unit outside and my air is running just as it should be. My unit is only 4 years old. Sometimes it pays to go with the best!
Over the last couple years, I've worked with both Dakota and Gary at Unique. They are both professional, punctual, and personable. The company itself is very accommodating and easy to work with, always out the same day if you need them. They're great with call aheads so you you don't have to sit and wait, wondering when someone will arrive. Highly recommended!
Unique Heating and Cooling did repairs to our furnace after our home was struck by lightning. They were responsive and friendly and were able to do the repair for us quickly! We liked them so much, we used them again to have a whole home humidifier installed and we love it! We will continue to use Unique Heating and Cooling and have recommenced them to all of our friends and family! Thanks Unique!!
