Job Locations and Reviews
Arrived at customers home to address no cool. Customer stated that the air is coming out but not cooling. I did look over the history as well and then proceeded with inspection. Upon inspection, I found that both units were running as far as than motors further inspection into the condenser showed that the compressor was not operating. I didn’t check the capacitor and found that it was dead rated for 45MF but was reading at 18. I replaced the capacitor temporarily just to further diagnose the unit I found that the system appears to be low on refrigerant as well as the compressor itself is slightly over. The over ramping of the compressor is due to operating a dead capacitor or an undetermined amount of time. The unit itself is also heavily impacted on the outside and is struggling to breathe. Assumption line also has essentially no insulation on it. The system is also an R 22 system. This refrigerant type has been phased out, and we currently do not carry R 22 in order to refill the
Came out today to complete one system HVAC, not maintaining temperature for the upstairs. Upon arrival, customer stated he had had several companies come out, and the system is still doing the same thing. Upon customers approval performed full system diagnostic and found carrier 2 1/2 ton heat pump/air handler for the upstairs. Upon evaluation, found that the compressor valves are bad, this is from the TXV sending liquid refrigerant back to the compressor. Also, upon evaluation found large amount of biological growth inside the system, no TE standard flood protection, no UV protection. It appears that the system for the downstairs and upstairs were swapped on initial build due to the upstairs and downstairs are the same square footage and the downstairs has a two car garage and the downstairs system is a 3 ton with only 2 1/2 tons of airflow. The upstairs system has low return airflow, but has 3 tons of supply airflow. At this time recommended updating the system with the correct size

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

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
