Save yourself time and nerves and find someone else! This company was recommended by a friend and I used Alex and Konstantin to service HVAC units on my rentals. They replaced condenser and coil unit in one of my rentals: offered 1 year service warranty and 10 years on the parts. Problems started 11 months later, when we had a leak in family room and master bedroom. Initially, we thought it was plumbing related, but it turned out it was AC leaked into the wall. House became a health hazard and tenant had to move out. I ended up replacing drywalls and flooring. Then hurricane Beryl came and we were out of power for 2 weeks. When finally we finished work and new tenant moved in, AC could not cool to the setting temperature (7-8 degrees above setting) and condenser runs non-stop. A clear sign of Freon leak. Alex did not want to come and told me he does not do a residential, but when I insisted, he stopped by and said the unit works properly with no leaks and freon pressure is 32 psi. 2 days later, AC did not cool again! We scheduled an appointment 3 days in advance and Alex was fighting me on the phone, coming up with excuses not to service the unit. read more
