Rose Rivera CEO of AARD Changing The Industry

Rose Rivera had the courage and tenacity to pursue a career in an industry dominated by men – she founded AARD Mechanical Air Conditioning & Heating. While her achievements are certainly commendable and her actions often groundbreaking, she is far from a solitary player. She has encouraged other female contractors to join the field, so that even more women can be bold and unafraid of entering into new – or existing – industries.

Honest Pricing For Honest Work

At AARD Mechanical, we believe in providing the best possible customer service for all of our clients. Whether you need a simple fix or a full-on replacement, you can count on us to offer competitive prices that you can feel good about. We fully support our customers investing in their homes, which is why we make sure not to break the bank so that they can rest easy.

You don’t need to worry about our team members trying to convince you to pay more for additional services. They are heating and cooling experts, not salespeople. 

Real Problems, Real Solutions

We know that things don’t always go as planned and we know that not everyone is an expert when it comes to heating and cooling issues. Fortunately, we are more than happy to offer you solutions that work. Instead of offering you quick fixes, we will let you know what needs to be done in order to overcome the situation and avoid any later reoccurrences. If there is something wrong with your systems that is likely to cause more problems down the line, we will let you know and also offer you any additional solutions that we can to keep your home at the right temperature for many years to come.
