"Technicians were courteous and polite, performed replacement of my 4 inverters and communicated with Enpase for recognition all within one hour. I highly recommend this group."

"They were very thorough and professional. Very personable."

"Never contacted me"

"The amount of times this company has no call, no showed for a problem with a unit they just installed is uncanny. Not to mention I was grossly overcharged for a service they aren’t even providing. Zero class. Zero accountability. Zero stars."

"This is the latest after HARP has been out to try and fix an AC system they installed. Mind you 4 different technicians have been to the property and none seem to have been informed on the repair or what it would take to fix it. I had another AC company come out an inspect the unit HAAP installed. This is what the report stated: ent to look at heat pump system in the apartment. Outside I found the condenser line set to be kinked, uninsulated, the wrong size and the system to already have dye added to the system so someone has tried to leak check the system. The problem with the dye is that it should never be used in a system because it contaminates the refrigerant and the oil in the unit, these actions have taken years off the operation of the unit. Inside starting at the thermostat to be wired incorrectly which may be a leading cause to why the system is running incorrectly. Also found that part of the ductwork was cut out of the way by the previous company and they did not put the duct work back together and in fact just covered the whole on the end of the duct. The line-set is wrong as it is suppose to be 3/8 3/4 line-set and it is only 1/4 1/2 line-set which leads to less life of the system and improper running of the system. In order to fix the system we would have to reclaim any refrigerant from the system and then un do the brazed connections, run line hide, drill out the building pull new thermostat wire and a new line-set between the two units, braze pull a vacuum, charge the system and then re wire the system. Also this would not insure proper running of the system because the system has already been damaged from the improper installation Task # EHR-100 RRL-160 RRL-170 LNS-110 LST-100 Description Rewire Low and/or High Voltage - Indoor Equipment : - Sometimes, an event occurs which may damage the wiring to a component in your system. There are two types: high-voltage (running motors, for example) and low voltage (usually running indoor thermostats). Repairing the damaged wiring will allow voltage to operate inside of the indoor unit. Add Initial lb of R-410A Refrigerant : - The refrigerant system is a "closed-loop system" meaning that it does not require being "topped off" like a gas tank. In fact, in most cases, the refrigerant in the system will actually last longer than the system. If the system requires additional refrigerant to be added, it usually means there is a leak in the system. It is important that the leak is located and repaired before the refrigerant is added. This is for the initial pound of refrigerant in order to start diagnosing the system, however, more may be necessary. Add R-410A Refrigerant Each Additional lb : Additional refrigerant was necessary. Refrigerant Handling Lineset - 50 Foot : The lineset is the copper tubing that connects the indoor coil for the air conditioning unit to the outdoor condensing unit. Sometimes it is possible to re-use an existing lineset. We recommend replacing the lineset where accessible. In some situations when the old unit fails it can contaminate the tubing. Reconnecting the tubing to a new system can shorten the life of the equipment. Repair Line Set : - If the line set is leaking refrigerant or has other issues, such as a kink in the line, repair may be an option, instead of replacement. includes pump down of system, pressure test, vacuum and testing the system. additional refrigerant NOT included. No one from HARP will return my calls at this point. My next step is to take them to Court to get my money back and find a reputable AC company that can perform the work and actually have technicians that know what they are doing. AVOID THIS COMPANY AT ALL cost. They are rip off artist."
