We got an estimate of $31,000 from another HVAC company to fix and replace units in my business. Turns out, the units did not need to be replaced and were fixable and endend up costing us roughly $5,500 with Air Dynamics! Super professional, knowledgeable, great to deal with and will not rip you off, please call them first! Will be recommending them over and over and using them whenever I need. Thank you soooo much for saving us so much money!
