KDC Air & Heat, LLC BBB Business Review

What Customers are Saying

Great, trustworthy company! Very knowledgeable, and efficient My schedule for repair work was so limited but they were able to work with me and to help make repairs convenient. Appreciate their professionalism and kindness. Would definitely recommend!

-Donna R.

I am absolutely in love with this company and their workers. They came out and checked everything out, cleaned the unit, and made sure my unit was in working order because my house was getting in the 80s with how hot it was outside. Unfortunately, it took a couple of times out to figure out that I needed a new air conditioning unit, with all of the follow-up visits not costing me anything. They came and installed my new unit yesterday! They were super polite and efficient, taking their time to get it done right and even clean up their mess before they left. I got my first good night's sleep in almost a month! THANK YOU!!!!

-Milisa G.

Very knowledgeable and professional.

-Mark F.

Responsive. Professional. Competitive. Knowledgeable. And no drama! It's the exceptional contractor that is all of the above but KDC is, making this a very easy review to write. I did my homework and now have two geothermal heat pumps installed in Louisiana, and one new HVAC company. I can rest assured knowing that KDC is well set up to handle service for many more years to come.

-William (Bill) S.

Very professional A/C service, showed up on time with 5 people and completed the work FAST. Kenney has all the newest equipment and diagnostic tools to find the problems FAST, that saves you money. KDC even has the coolest looking trucks. Kenney's people are the BEST, don't waste your money elsewhere!!!!

-Billy D.

Very knowledgeable and quick response time.
