shantan singireddy

Lareik was amazing, fixed the clogged condensate line, and got our unit running amazing. About 2 weeks prior he also helped my parents save 4000 dollars, as he provided a second opinion. Another HVAC company told my parents that the entire unit had to be replaced, it is a two year old unit. Lareik diagnosed the unit, was able to find the issue was a bad capacitor, which he replaced all in less than 30 mins when the previous company spent over an hour diagnosing the unit.

Response from the owner:Hi, Shantan. Thanks for taking the time to share your positive experience. We truly appreciate it!

Excellent customer service from Brandon. He came out, fitting me into a busy day, but was able to finish before his next appointment.

I will definitely be working with Brandon again!

I recently had my A/C stop working. Brandon B. quickly diagnosed the problem and repaired my blower motor to bring my A/C back to blowing cold. In addition, the repair quote was less than other well known A/C companies in the Lutz area. FL Air Heating and Cooling just earned a new loyal customer. A++

Great service! I was late because I was at long term facility with my husband was just admitted a few days ago, we are both in a state of, so I never want to leave him there. I was so engrossed with his that I forgot my appointment. When I realized that I was going to be late I panicked and rushed home. When I got near my house I realized that the service worker was waiting for me. I got very emotional because he was very kind to me and he didn’t know anything about my husband’s new change of life. Boy, did I need that this compassionate moment!
Thanks and I will never forget it
