    Status:
    Answered

    On September 22 My outside unit the fan was not turning on I called them because they installed the heat pump so I trusted them to fix it. I called them and they came out and attempted to reinstall the blower at my hone but was unable to.  So he took the part with him and said they would call when the part came in.  That never happened.  I had to constantly call them and every time I called I was given excuse after excuse. They never called about a date to install so I called them and they said they ordered the part and should be here Wed. They received the order but the box was empty which is extremely suspicious.  They didn't even bother to ask the warehouse why they delivered an empty box.   I had to call off work for them to install the part but when they came out they found another issue with the defrost panel.  So again they were unable to fix it and had to order another part.   I have paid over 600 dollars for a portable AC unit to cool myself during this time.  When he came to put freon in the unit he saw that the cylinder was also bad  so that would cost me another 800 dollars more. They continued to put the blame on everyone else and take no responsibility for the amount of time and money I have spent trying to get this resolved.  I have been more than patient.  They also tried to hot wire the blower motor to my breaker box and I told them no. I cant use the heat or the AC I have to use emergency heat.   Wendy the receptionist was very unprofessional.   She told me that her workers should not have to work around cat feces and I do not own a cat. So now my emergency heat is not turning on and now they tell me they still do not have to correct part and have no idea when it will be here. The manager said he didn't know anything about the situation but said it would be 2 weeks but no one told me that,  As of now nothing has been done.

    When I called I asked for them to come take a look and tell me what they thought was wrong with my ac. That information was obviously not forwarded to the technician. When he came he stated it needed Freon. I asked if that was the issue, oh yeah. Ok, Im not an hvac person. So took his word. I said it runs constantly and never shuts off. Oh this will do the trick. Hmm well then he asked do you want dye. What is dye I asked. It basically does their job for them as they cant see a leak with the naked eye. So $477.09 later and still at the same spot I was before I even called!!!! This was done on a Friday, I called Monday morning asking if the dye could be checked sooner then the 2 weeks he said to call back to have someone come out and look. The lady says no and that I had to wait the 2 weeks for the dye to work through the coils. I said let me guess another charge? Yup, cause we are coming out?!? Really??? First the technician did not say a word about another service charge, 2nd this dye is doing your job. 3rd $477.09 and still no difference then before! But oh yup thats my problem!! All I wanted was to find out if the system was to small for my place! I already had someone come out a week before them. I just wanted a 2nd opinion and didnt tell them because I didnt want them to care less or didnt do their job. Also didnt want to tell them what the previous guy said because i wanted them to think for themselves! Anyways the lady referred me to their customer complaint guy. Didnt hear from him so i called mid day the next day. Spoke with him. He says Ill call you back after I speak with my boss ok. Calls me back and says Ill have another technician come out and take a look at the unit and measure (this was after I told him what the first hvac *** said) this was Thursday a little after 10am that this last guy came. Friday passes and nothing, Monday comes still nothing so late afternoon Monday I had my husband call. Check their fb page.

    We have a full hvac service department that responds to calls in the order they are received. This customer requested a service call, not an estimate. The unit was low on freon. Advised the customer that freon could be added and coil cleaned plus dye added if she'd like to see if it could be repaired instead of replaced. She gave the go ahead to continue. Standard procedure is to wait two weeks for the dye to work it's way through the equipment. Customer did not want to wait two weeks. As a courtesy to customer, we sent the first available technician to do an INSPECTION of the entire hvac system at no charge. The customer was informed of our recommendations. After our experience with this customer, prefer to no longer do any work for them as we do not subject our employees to hostile work environments.
