Arrived at customers home to a no cool. Customer explained that a lightning storm struck the house knocked out the system. Upon initial inspection, I found that the blower motor was blown and transformer. Both components were replaced and air handler was back online. With those aspects fixed and power now going to the outdoor unit. I then found that the control board was bad as well. I replace the control board and found that the control board that was just purchased was bad out of the box. For the time being, I have bypassed the control board to allow for system operation and cooling, but I will have to return in order to replace the board with a functioning board

Our water heater began leaking, we called on Saturday and were able to get an appt for Monday. Martin called and gave us his ETA and arrived exactly when he said he would.

Technician was amazing. Made sure I was happy with everything he was doing and was very helpful in every way possible.
I was very concerned about my AC unit, thinking the worse. I appreciate Mark taking me through my options, the first time everything was explained in depth . I appreciate his knowledge and the truth.
Excellent experience and fast service!
Excellent Service
While being serviced I also had a “class in session” moment with my technician Mark Hilson😂. He taught me a lot about how to treat my system better as a first time home owner. I was doing an awful lot of things wrong and neglecting my poor system until it got fed up and left my family to die😩. He was a second opinion btw because I didn’t feel comfortable with the other company and I was right! They tried to get me out of $2000 to do absolutely nothing that was gonna fix the problem! All my system needed was a good cleaning and now we are back in the AC. This company is the most reliable and trustworthy I’ve run into. Thank you! Will be doing further business in the very near future.
Very through and explain to us in great detail what the problem was
