"I cannot recommend them enough! Very respectful professional men who truly care about the customer and quality of work. After my condenser was flailing and I was losing coolant they were able to do a temporary fix and checked on me as we waited for the new unit to come in. Especially in this heat it was very reassuring. You will get the best they have from them!"

Pam L.
"I contacted Misael because my air conditioner was taking forever to cool down my house. I had to get my air handler replaced because it was leaking refrigerant and getting worse each season. It only took 2 days for them to come out and install it, and they even stayed until about 10 pm to get everything installed, checked, calibrated, and start working. Would highly recommend for quick service at a fair and reasonable price."

"Misael came to our home with urgency when we told him that our A/C unit went out during the excruciating heat. We are beyond grateful that he was able to fix the problem for us in a timely manner and was knowledgeable about our A/C system. Now we know who to call for assistance in the foreseeable future. 10/10 recommend Fierce Mechanical!!"
